1General information

How to read this manual

Marks in the text

Note	Something worth knowing — an extra capability, a shortcut.
Warning	Something that must be remembered. Ignoring it costs work or damages equipment.

Access levels

Operator	The level the panel starts at after every power-on. Everyday work.
Agronomist	The commissioning settings and the resetting of the statistics. Needs a PIN, which is different for every panel and is given in the device passport.
Service	The profile, the readdressing of devices, the “Reset to defaults” items. Used by the service department.

What a press means

Short press	Press and release.
Long press	Press and hold until the panel reacts. Several buttons do something different when held.
Double tap	Two quick taps on the screen. On the home screen it does the same as holding “BACK”.
Two-finger tap	A tap with two fingers on the screen. On the home screen it does the same as “MENU”.

Terms

Rates and control

Rate	The target intensity the operator sets. The panel compares the actual intensity against it and reports a deviation that is too large.
Rate error	How far the actual intensity may stand from the rate before that becomes an alarm. Set per sensor group, in per cent.
Product application control	The panel does not judge the sowing at every moment: it starts watching only once the conditions for it are met — the implement is lowered and moving. Until then a silent section is not a fault.
Minimum alarm rate	The lowest intensity still counted as normal. Below it the section is reported, whatever the neighbours do.
Path interval	The stretch of the run over which skips, doubles and the other figures are gathered before they are redrawn. Set by the “Recalculation,m” parameter, which the panel renames “Recalculation,sec” when the seeding mode counts in seconds rather than in metres.
Manual lock	The operator can stop all product application by hand, with a long press of “HOME”. A hand icon on the home screen shows the lock is on.

Sensors

Section control sensor	The common name for a seed, dry fertilizer or liquid fertilizer sensor. One per section of the implement.
Seed sensor	Counts the seed passing one section. On a row-crop planter it also separates doubles and skips; on a grain drill it measures intensity only — the seeds arrive too close together to be told apart.
Dry fertilizer sensor	The same device, watching a granular fertilizer line.
Liquid fertilizer sensor	A flow meter counting the volume through one section.
Speed sensor	Measures the travel speed. Everything else — distance, area, every rate — is calculated from it.
Dispenser sensor	Watches that the dispenser shaft is turning.
Fan sensor	Watches the fan speed against a set minimum and maximum.
Pressure sensor	Watches positive pressure or vacuum, depending on how it is plumbed.
Hopper sensor	Reports when the product has fallen below the point where the sensor sits.
Work position sensor	Tells the panel whether the implement is lowered into work or raised for transport.
Marker sensors	Report which mechanical marker is down, so that the bout of the tramline rhythm can advance by itself.

Tramline

Tramline	A driving lane left unsown, made by shutting off one or several sections on chosen bouts.
Rhythm	The repeating sequence of bouts, with the bouts on which particular sections must not sow marked in it.
Bout	One pass of the implement across the field. The rhythm counts them and returns to the first when it runs out.
Tramline actuator	The device that shuts the sections off. One actuator controller carries three things: the actuator itself and both marker sensors.

Devices

HUB8 (input device)	An eight-channel hub for sensors that have no controller of their own. It watches them and reports them to the panel as if each were a device.
Electric motor controller	Drives one or two dispenser motors, or the liquid fertilizer pump. Motors and pump share one controller design — which is why a machine cannot have a pump without also having the controller that a motor would use.
SCM	Section Control Module — the interface through which a third-party navigation system can shut sections off.
microSD	The memory card, for reports, profiles and firmware updates. FAT16 or FAT32 only.

What is supplied

The minimum system is the Hectare ONE panel and the seed sensors — one sensor per section. Agriwelt seed sensors have their own controller and are connected to the panel directly.

Everything else is optional, and what a machine carries is written into the panel’s profile:

Pressure sensor	Up to three, for pressure or vacuum.
HUB8 input device	For sensors of the “open collector” kind — speed, hopper, fan, dispenser, work position, markers, Wilger flow meters.
Dispenser electric motors	With their controller, for applying seed or dry fertilizer to the rate.
Tramline actuators	Up to four.
Electric pump controller	One, for liquid fertilizer — UAN, micro-fertilizers and the like.

What the system does

Seed

• Applies seed to the rate the operator sets, through the dispenser electric motors — on row-crop planters and on grain drills.
• Watches the actual sowing against that rate and reports a section that falls behind.
• Reports a blocked or empty tube by its number.
• Counts seeds, doubles and skips — on row-crop planters.
• Accepts a section shut-off signal from a third-party navigation system.

Dry and liquid fertilizer

• Applies liquid fertilizer to the rate through the electric pump.
• Watches both dry and liquid lines and reports a section that falls behind or blocks, by number.

The machine around the product

• Hopper level, dispenser shaft rotation, fan speed, air pressure or vacuum, travel speed — each against its own limits.
• The sensors of an autonomous fan-drive engine: oil pressure, battery charge, ignition, fuel level, air filter.
• Working or transport position of the implement.

Tramline

• Creates the tramline with actuators or by stopping dispenser motors.
• Advances the bout by itself from the marker sensors.
• Keeps watching the sections that are shut off, so that a section leaking into the tramline is still reported.

Records

• Treated area, separated into what was sown and what was lost to skips.
• Detailed statistics of the run, and reports written to the memory card.
• Firmware of the devices in the system updated from the same card.

2Safety

This chapter holds the instructions that keep work with the Hectare One system safe. Read it before the panel is switched on for the first time.

Obligations and liability

Follow this manual. Knowing the basic rules and instructions for safe operation is the precondition for working with the system safely and without interruption. This manual is part of the delivery: keep it on the machine or in the tractor cab.

Warranty and liability. The general terms of sale and delivery of Agriwelt GmbH apply. Claims for warranty and for damage to persons or property are not accepted where the cause is one or more of the following:

• use of the system other than as intended;
• improper installation, commissioning or operation;
• disregard of the instructions in this manual on commissioning, operation and maintenance;
• unauthorised modification of the equipment.

Intended use

The Hectare One system is intended solely for use as a monitoring and control device for sowing and for the application of dry and liquid fertilizer on agricultural machines — mounted and trailed seed drills, planters and cultivators.

Following every instruction in this manual is part of intended use.

Any other use is not intended use. The manufacturer is not liable for damage arising from it; the risk is borne by the user alone.

General precautions

Besides the instructions in this manual, observe the national safety and environmental rules that apply where the machine is worked, and the safety instructions of the implement and of the tractor.

The operator’s workplace

The system is operated by one person, from the driver’s seat of the tractor.

Working safely with the system

The panel is not only an indicator. It drives machinery. The dispenser electric motors, the liquid fertilizer pump and the tramline actuators are started by commands from the panel, and several of those commands work while the machine is standing still.

Before approaching the implement, stop the machine, switch the tractor ignition off and take the key with you. Do not rely on what the panel shows: a device whose control has been switched off reports nothing about its state.

Handling the panel

• Do not subject the panel to impact or heavy vibration, and do not drop it.
• Do not touch the screen with sharp objects; the touch surface is damaged by them.
• Do not open the housing. It is sealed and carries a pressure equaliser; opening it destroys the seal. Repairs are carried out by Agriwelt service only.
• Keep the harness connector, the GPS antenna connector and the memory card slot closed and clean when nothing is plugged into them.
• Do not clean the panel with solvents or with a pressure washer. A damp cloth is enough.
• Connect the panel only to a supply that meets the parameters given in the device passport. Reversed polarity and voltage outside the permitted range damage the electronics.
• Disconnect the panel before electric welding is carried out on the tractor or on the implement.

Warning symbols used in this manual

Safety instructions in this manual are marked with a signal word. The signal word says how severe the consequence is if the instruction is ignored.

Signal word	What it means
DANGER	An immediate threat with a high degree of risk. Ignoring it leads to death or to the severest injuries.
WARNING	A possible threat with a medium degree of risk. Ignoring it can lead to death or to severe injuries.
CAUTION	A threat with a low degree of risk. Ignoring it can lead to minor or moderate injuries.
IMPORTANT	No threat to people. Ignoring it damages equipment, or costs work that has to be done again.
NOTE	Information that helps the operator get more out of the system.

3Control panel

Appearance

The seven buttons

The seven buttons are in a row under the screen. Press one with a fingertip. They are always in this order, left to right:

4Basics of the graphical interface

Everything you do on the panel happens through five things: the working screens, the menu, the context menu, the number pad and the windows that ask or tell you something. This chapter explains those five. What each screen holds is in its own chapter.

Switching on

After the power is switched on a splash screen with the logo appears. It stays until the panel has found every device connected to it — a few seconds — and then the home screen opens.

The working screens

Four working screens follow one another in a circle, and the “HOME” button steps through them. A fifth screen replaces the home screen on machines without seed sensors.

The menu

Press “MENU” on a screen that has one. The selected item is shown as black text on a light blue band. “UP” and “DOWN” move between items.

What you see	What it means
an arrow head on the right	The item opens another menu. Press “MENU”.
A value between - and +	Change it with “PLUS” and “MINUS”, right there in the list.
A value between -[ and ]+	Pressing “PLUS” or “MINUS” opens the number pad.
Nothing beside the name	The item performs an action. Press “MENU”.

The context menu

The context menu belongs to one device — a sensor, a motor. To reach it, hold “MENU” down on the home screen to enter the sensor setup mode, move to the device you want with “UP” and “DOWN”, and press “MENU”. The selected element is framed in white.

A long press on a device does the same without entering the mode at all.

Entering numbers

When a value is written between square brackets, changing it opens a number pad.

Type the value with the keys and touch OK. The panel refuses a value outside the permitted range for that parameter.

Windows that ask, and windows that tell

Every window the panel opens has the same shape: one box in the middle of the screen, a full-width coloured strip along its top with a word in it, the message under the strip, and the buttons — if there are any — along the bottom.

Read the strip before you read the message. Its colour and its word say what kind of window this is, from across the cab:

Yellow, “Confirmation”	The panel is asking. Two buttons — the green one confirms, the red one cancels. The “BACK” button also cancels. Nothing happens until you answer.
Blue, “Information”	The panel is telling you what happened. Some of these close by themselves, some wait for any button.
Red, “FAILURE”	An alarm. The text, the kind of device, and the addresses of the devices reporting it. See below.

Alarm windows

An alarm window holds three things: what happened, on what kind of device, and which devices — the addresses are listed when several identical sensors report the same fault at once.

Touch Close in the window	Closes this alarm. The next one in the queue appears.
The seven buttons	Only HOME works, and it lights up while the window is open. A short press closes the alarm, the same as the touch on Close; a long press closes every open window at once and returns to the home screen. The other six buttons are dark and do nothing.

5Home screen

The two modes of the home screen

The home screen works in two modes, and the buttons mean different things in each.

Mode	What it is for
Monitoring	The mode the panel starts in. The operator watches the application of the seed material and can change the target rate.
Sensor setup	Selecting individual sensors, taking them into control or out of it, opening their settings.

The buttons

Button	Monitoring	Sensor setup
HOME	Next working screen	Leaves setup, next working screen
HOME held	Locks and unlocks the product application control, with a beep. The hand icon shows the lock.	The same
BACK	The tramline bout menu, if the tramline is switched on. If a rate field is blinking, cancels the blinking first.	Leaves setup, stays here
BACK held	Calculates the minimum alarm level automatically, from the rate being applied. Only while applying. A double tap does the same.	—
MENU	The main menu. A two-finger tap does the same.	The context menu of the selected sensor
MENU held	Enters the sensor setup mode	—
PLUS	Raises the target rate. The first press selects a field and makes it blink.	Takes the sensor into control
MINUS	Lowers it, selecting the same way.	Takes the sensor out of control
UP / DOWN	Move between rate fields. Nothing if the machine has only one.	Previous / next sensor

The home screen of three machines

The same panel, three different machines. What the home screen shows follows the profile: every group of sensors and devices entered there gets its tiles, its columns, its rate field. The three screens below were taken on one panel, firmware 1.2.3, standing still — the target rates are set, the actual rates are zero.

The home screen at work

The same eight-row machine as above, seeding: simulated speed on the bench, seed flow imitated by the sensors themselves. Each column is one row; the tops of the columns move with every count, the letters and colours say what the row is doing. The picture is a series of frames from the panel, about seven seconds apart.

The line: the twenty-four-row drill at work

The second machine — twenty-four seed rows and twelve fertilizer rows — seeding at 12 km/h with the flow imitated by the sensors. The series starts with the columns below the line and the red NOT UNDER CONTROL over both diagrams, then the target is lowered, the columns rise above the line and the monitor takes the rows under control again.

Forty-four rows at work

The third machine — forty-four seed rows in two diagrams, two hoppers, two dosing shafts — seeding at 12 km/h with imitated flow.

Ninety-six rows, three hoppers, two fans

The largest machine of the four: forty-eight seed rows and forty-eight fertilizer rows in two diagrams, three hoppers, three dosing shafts, two fans. Seeding at 12 km/h with imitated flow. The series starts with both diagrams below the line and NOT UNDER CONTROL; then the target comes down to the real rate, the columns rise above the line and the rows are under control again.

The home screen of a real machine

The screen below was shot on a machine with forty-eight seed sensors in two rows, two hoppers, two dispenser shaft sensors and one fan, while it was sowing.

The picture below was shot on a different machine — eight seed sensors, two dispenser electric motors, two hoppers, two dispenser shaft sensors, one fan — standing still, and shows the indicators along the top in more detail.

What is on it, from the top:

Element	On this screen
Travel speed	The large yellow figure at the top left. Yellow because the machine is standing still.
Hopper sensors	Two hopper icons, numbered. The first is green, the second red — that hopper is reporting an empty state.
Dispenser shaft sensors	Two round icons, numbered 1 and 2.
Fan sensor	The fan icon with its number, and the measured speed in rpm beside it.
Processed area	The hatched hopper icon with ha and the figure below the speed.
Actual seeding rate	The ear icon with ths/ha — thousands of seeds per hectare.
Memory card	The card icon at the top right, shown while a microSD card is inserted.
Diagram of the seed sensors	The eight columns, numbered along the bottom. The tolerance in force is written above the diagram.
Rate and spacing	The figures to the right of the diagram: the rate, and the seed spacing in s/m.
Manual lock indicator	The yellow hand at the lower right. It appears while the product application control is locked by hand.
General failure indicator	The red letter box below the hand. It reports a fault of the dispenser electric motors or of the tramline actuators.

The speed field

The field that normally shows the travel speed also carries the messages about the speed. They replace the figure and blink, about once a second, so that the figure remains readable.

What is shown	When
FASTER, on a red background	The travel speed is below the minimum set for the speed sensor.
SLOWER, on a red background	The travel speed is above the maximum set for the speed sensor.
IMITATION, in yellow	The speed is not being measured but simulated from the setting of the speed sensor. Nothing that depends on the speed can be trusted in this state.
Increase / decrease the imitation	The simulated speed itself is outside the permitted range. The message asks for the setting to be changed, not the travel speed.
A message about the sensor	One of the two speed sensors has failed, or the minimum and the maximum speed contradict each other.

The second home screen

The two electric motors are shown along the middle strip with their numbers, their load and their state.

The icon of each motor alternates, about once a second, between the picture of the motor and the sign of its state — STOP for a motor that is not running, a red cross for a motor in a fault state. The two frames here were taken in the two different phases.

The green and red chevrons at the ends of the rate strip mark the direction in which the target rate will move when it is changed.

6Indicators of the home screen

How to read any indicator

Almost every indicator on the home screen follows the same rule. Learn it once and you can read an indicator you have never seen before.

What you see	What it means
Green icon	Normal. The device answers and its value is inside the limits.
Red icon, blinking	Alarm. The device answers, but the value has left the limits. An alarm window follows after the alarm delay.
The icon changing to a red ×	No answer from the device. The panel alternates between the icon and the × so that you see which device is silent. The value is shown as XXXX.
The icon changing to a white [!]	The device is in the profile, but its control has been switched off. Nothing about it is being watched. The value is shown as !!!!.
Yellow icon	Not a fault. A state you have chosen, or one that only needs your attention: implement raised, markers up, ignition off, application locked by hand.

Clock

The clock slot stands at the top left of the screen. It does not always show the time — it is one slot shared by several messages.

What you see	What it means
The time in white	Normal.
BAT in red, for about a second in every four	The internal battery of the clock is low. The clock still runs; replace the battery before it stops. Between the flashes the time is shown in red.
XX:XX in red, blinking once a second	The clock chip does not answer. The panel has no date and no time, and everything it records will carry the wrong one.
IMITAT in yellow	Speed imitation is switched on. The panel shows this instead of the time so that the mode cannot be forgotten.
The slot changes every few seconds	The trial period is running. On a loop of about eight seconds the slot shows the time left in blue as hours:minutes, then the word TRIAL, then IMITAT if imitation is on, then nothing. When the first row has no room for the clock, the whole loop appears only once every 30 seconds, and the sensor indicators show through in between.

Memory card

Shows whether a microSD card is in the slot. There are only two states: the icon is there, or it is not.

Speed

The travel speed, at the top left of the screen.

What you see	What it means
A number in white, e.g. 10.0	Normal. The speed is inside the permitted range.
SLOWER on red	You are driving faster than the maximum set for the speed sensor. Slow down.
FASTER on red	You are driving slower than the minimum. Speed up.
XX.X in red	No answer from the input device that carries the speed sensor.
A number in yellow with IMITATION	The speed is being imitated by the panel for testing. The real sensor is not used, and nothing you see about rates is real.

Product application locked by hand

A yellow hand, blinking, at the right edge of the screen. It means the operator has locked product application: the machine will not apply anything, however it moves.

To lock or unlock	Hold HOME down on the home screen. One short beep confirms the change.
While it is locked	The yellow hand blinks on the screen. Nothing else happens — there is no repeating sound.
When it is not locked	The icon is not shown at all.

Tramline bout

Shown only if the system has a tramline actuator. The number on top is the current bout, the number below it the number of bouts in the rhythm.

White, e.g. 1 over 3	The current bout is an ordinary one. The figure tells you how far you are from the next tramline.
Blinking	The current bout is the tramline bout. The rows of the tramline are being cut off.
Yellow	The bout will not change by itself. Either automatic bout change is switched off, or the sensor it depends on is missing, silent or not under control. The bout has to be changed by hand.

Fan

The rotation speed of the fan in revolutions per minute. Green is normal; red means the speed is above or below the permitted one; the × and the [!] have the usual meaning.

Hopper

The level of the seed material in the hopper. A full green hopper is normal; an empty red one means the level has fallen below the sensor and refilling is needed.

Metering unit

The rotation of the metering shaft. While the shaft turns, the icon animates; that animation is the fastest way to see that the metering unit is actually running. Red means there is no rotation, or the speed is not the one required.

Product rate by weight

Shown only when the dispenser motors are set up to apply products by weight. The indicator carries two numbers: the target rate on top and the actual rate below, in kg per hectare.

Target green, actual white	Normal. The machine is applying what was asked of it.
Target red, actual white	The actual rate is above or below the permitted deviation from the target.
The field is highlighted and the cursor blinks	Rate setting mode: only the target is shown and PLUS and MINUS change it. Touch and hold the field to enter this mode.
The field is highlighted but does not blink	Setting mode is on, but the cursor is on another indicator. This one shows its target and waits.

Dosing by weight is not possible

A red blinking product icon. It appears when the panel has worked out that the target rate cannot be held at any travel speed: the lowest speed at which the metering rollers can deliver the rate is already at or above the highest speed at which they can.

Pressure

The vacuum or the positive air pressure in the distribution system, in kPa. Green is normal; red means the pressure is above or below the permitted one.

The sensors of the autonomous fan drive engine

Oil pressure. Green is normal. Red means the oil pressure of the engine has fallen below the permitted level.

Battery charge. Green is normal. Red means the battery of the engine is not being charged.

Ignition. A green key means the ignition is on and the engine sensors are being watched. A yellow key means the ignition is off — this is not a fault, but nothing about the engine is being watched either.

Fuel level. Green is normal. Red means there is little fuel left in the tank of the engine.

Air filter. Green is normal. Red means the air filter is clogged and has to be cleaned or replaced.

Markers

The position of the markers. The icon shows which side is down.

Green, both arms down	Both markers are lowered.
Green, one arm down	Only that marker is lowered — the left one or the right one, as drawn.
Yellow, both arms up	Both markers are raised. Not a fault; on a machine that changes the tramline bout by the marker, the bout changes at this moment.

Implement position

Whether the implement is in the working (lowered) or in the transport (raised) position. Green is lowered and applying; yellow is raised and not applying.

Actuator failure

A single red icon that stands for all the electric motors and tramline actuators together. It is not shown at all while everything is in order.

Red	At least one actuator is in the alarm state.
White [!]	The control of at least one actuator has been switched off. No fault has been found — but that actuator is not being watched.

Liquid fertiliser pump

Depending on the equipment, the pump is watched by two or three indicators.

Rate, in l/min	The main indicator. Only this one can be selected in the sensor setup mode and only it has a context menu with the pump parameters.
Load, in %	How hard the pump is working. It disappears first if the home screen has no room for it.
Pressure, in bar	Shown only if the pressure sensor is fitted and switched on in the settings of the pump controller.

The rate indicator

Besides the usual green, red, × and [!] states, this indicator has two of its own:

• A yellow pump with STOP — application is locked by hand, or the implement is raised. The pump will not start when the machine moves.
• A highlighted target rate — there are no section flow sensors in the profile, so there is nothing actual to show. The figure is the target, not a measurement.

The load indicator

Green is normal. At 99 % and above the indicator turns yellow: the pump is at its limit and cannot follow a further increase in speed. Drive more slowly, or the rate will fall below the target.

If the controller reports no load figure at all, the indicator shows —- and blinks red.

The pressure indicator

Green is normal. Red means the liquid pressure is too high — reduce the travel speed, or raise the “Max pressure, Bar” limit in the settings of the pump controller if the line really can take it.

7Working screens — navigation

The working screens

The control panel has four working screens arranged in a circle, plus a fifth screen that stands apart and replaces the home screen on machines of a different type.

Screen	What it is for
Home screen	The main working screen: the diagrams of the section control sensors, the state indicators of the devices, the speed, the area and the rate.
Table	The readings of every section in figures, as a scrolling list. Several tables are available depending on the control mode.
Statistics	The results of the work by field: area, path, quantity of the products applied.
Motors	The state of the dispenser electric motors, and of the tramline actuators if the machine has any. Present whenever the profile contains at least one electric motor or one tramline actuator.
Alternative home screen	A second home screen for machines without seed sensors — see the separate section below.

The circle of the working screens

The “HOME” button moves from one screen to the next, always in the same direction, and returns to the home screen from the last one:

Home screen → Table → Statistics → Motors → Home screen.

The alternative home screen stands outside that circle: it is opened from the home screen with a swipe to the right and closed with “HOME” or a swipe to the left.

What the screens look like

Moving between the screens

Every transition can be made with a button, with a swipe of one finger across the screen, or with both. A swipe has to be a long one — a short movement is not recognised as a transition.

From	Action	To
Home screen	HOME, or swipe left	Table
Home screen	Swipe right	Alternative home screen
Table	HOME, or swipe left	Statistics
Table	BACK, or swipe right	Home screen
Statistics	HOME, or swipe left	Motors (Home screen, if the machine has none)
Statistics	Swipe right	Table
Statistics	BACK	Home screen
Motors	HOME, BACK, or swipe left	Home screen
Motors	Swipe right	Statistics
Alternative home screen	HOME, or swipe left	Home screen

The alternative home screen

It is opened from the home screen with a swipe to the right and closed with the “HOME” button or a swipe to the left. It is not part of the circle of the “HOME” button.

Action	Result
MENU, or a touch on the settings field	Opens the main menu
Swipe up or down over the rate field	Changes the seeding rate, within the permitted limits
A long press on an electric motor	Opens the context menu of that motor
HOME held down	Locks and unlocks the product application control, with a short beep

Two ways of doing the same thing

Almost everything on the working screens can be done either with the buttons or with a gesture. The table below pairs them, so that neither an operator who works by the buttons nor one who works by touch has to guess.

Screen	What it does	Button	Gesture
Table	Scrolls the rows	UP / DOWN	Swipe up or down
Table	Switches to the previous or the next table	MINUS / PLUS	Long swipe left or right with two fingers
Table	Asks whether to zero the readings	MENU, confirmed with PLUS	Tap with two fingers
Statistics	Scrolls the list. Holding the button down scrolls a whole screen at a time	DOWN / UP	Swipe up or down
Statistics	Changes the number of the field whose results are shown	PLUS / MINUS	Swipe left or right with two fingers
Statistics	Opens the menu of the screen	MENU	Tap with two fingers
Home screen	Calculates the minimum alarm level automatically	BACK, held down	Double tap with one finger
Home screen	Opens the alternative home screen	— none —	Swipe right

8The Table screen

The Table screen shows the readings of every section as figures, one row per section. It answers the question the diagram on the home screen cannot: which section exactly, and by how much.

Open it from the home screen with “HOME”. Leave it with “BACK”.

The three tables

The screen holds several tables. The corner tells you which one you are on — the number and the total, between a minus and a plus sign: those are the two buttons that switch.

Which tables your machine has

Table	Shown when
Seed counters	Always.
Rate per area Rate per distance	Only in the “Precise” seeding control mode.
Dry fertilizer	The machine has fertilizer sensors and the fertilizer control mode is not “Precise”.
Liquid fertilizer	The machine has liquid fertilizer sensors.

The columns

Column	Meaning
#	The number of the section.
sds/m	Seeds per metre, measured now.
Q.%	Singles — the share of correctly placed seeds.
Db%	Doubles — two seeds where one was intended.
Sk%	Skips — a gap where a seed was intended.
ks/Ha or sds/m	The applied rate: thousands per hectare in the first table, seeds per metre in the second.
%	The deviation of this section from the rate that was set.
seeds	In the counters table — the number of seeds this section has sown.

Working with the screen

What you want	Button	Or gesture
The next or the previous table	PLUS / MINUS	Long swipe left or right with two fingers
Scroll the rows	UP / DOWN	Swipe up or down
Zero the readings	MENU	Tap with two fingers
Go to the Statistics screen	HOME	Swipe left

9The Statistics screen

The Statistics screen is the report of the work: how far you drove, how much you covered, how much you sowed, and how evenly. It is kept separately for each field and survives the power being switched off.

Open it from the Table screen with “HOME”, or press “HOME” twice from the home screen. Leave it with “BACK”.

The report, from the top

The screen is one long list. Scroll it with UP and DOWN — hold the button and it moves a whole screen at a time.

Section	What it holds
Work on the field	Distance driven, area covered, operating time, average travel speed, and when the work started and ended.
Work without alarms control	The part of the same work that the monitor was not watching — driven with the control switched off or locked.
Speed control	How far and how long you drove outside the permitted speed range.
Seeding	The quality of the sowing as a whole — see below.
Fertilizing, Liquid fertilizer	The same for the other products, if the machine applies them.
Seed sensors	The same figures again, but for every section separately.

Reading the seeding block

Quality	The share of seeds placed singly, as intended. This is the number to judge the work by.
Doubles	Two seeds where one was intended.
Skips	A gap where a seed was intended.
Not sown	The share of the run when nothing came out at all.
Actual / Target	What was applied against what was set, in thousands per hectare and in seeds per metre. The percentage is the deviation.
Sown / Not sown / Unknown	The field split three ways in hectares, with a bar. Unknown is the area driven while the monitor could not judge — it is not a fault, but it is not proof of work either.

Section by section

This is where an uneven drill shows itself. One section with a lower quality than the rest, or a longer red part of the bar, points at that row: a blocked outlet, a worn disk, a sensor that needs cleaning.

10The Motors screen

The Motors screen shows the dispenser electric motors of the machine, one tile each, and the tramline actuators if the machine has any. It is the screen to look at when a row stops sowing and you want to know whether the motor is the reason.

It exists on any machine whose profile contains at least one electric motor or one tramline actuator. Reach it with “HOME” from the Statistics screen. Leave it with “BACK”.

Reading a tile

The colour of the symbol is the state. The value beside it is the driven shaft speed in rpm — or, in the “Precise” control mode, the seeds per metre measured by the seed sensor of that row.

Symbol	Value	State
Motor, green	the figure	Normal. The motor is under control and being driven.
STOP, yellow	the figure	The motor is serviceable, but the product application control is switched off. Nothing is wrong with the motor — the system is simply not applying.
Motor, red	the figure	The motor is in an alarm state. Look at the alarm itself for the reason.
×, red	XXX	No connection to this motor. Check the cable and the connector before anything else.
?, red	???	The monitor cannot tell what this device is: either another type of device answers at this address, or the controller has stayed in its firmware update mode.
!, outlined	!!!	The motor has been removed from control by the operator. It is not driven and not watched.

11Quick start

This is the order of getting ready. Your machine may not have every step — skip what it does not have.

Before the field

1	Calibrate the speed sensor. Everything else — area, rates, deviations — is calculated from the speed. A wrong speed makes every other figure wrong with it. “Settings” → “Seeding machine parameters” → “Speed calibration”, at Agronomist level.
2	Calibrate the metering rollers, on grain drills and on row-crop planters whose fertilizer dispenser is driven by an electric motor. From the context menu of each dispenser or motor, at Operator level, standing still.
3	Check the tramline rhythm, if the machine creates a tramline: Settings → Tramline.
4	Check the sensor parameters — the list is below.
5	Check each section: is it under control, is it applying. Both are set per section on the diagram.
6	Choose the field on the Statistics screen. For a new field, reset its statistics first.
7	Set the rates — seeding, dry fertilizer, liquid fertilizer.
8	Check the user level. It must be Operator.

Sensor parameters to check, by sensor type

• Speed sensor — “Min speed, km/h”, “Max speed, km/h”
• Dispenser sensor — “Period, s”, for each sensor
• Fan sensor — “Minimum, rpm”, “Maximum, rpm”, for each sensor
• Pressure sensor — “Minimum, Pa”, “Maximum, Pa”, for each sensor
• Liquid fertilizer pump — “Pulses per liter”, “Max pressure, Bar”
• Seed and dry fertilizer sensors — “Fraction”, “Correction”, “Recalculation,m” or “Recalculation,sec”. In the “Precise” or “Hybrid” mode also “Rate error,%”
• Liquid fertilizer sensors — “Rate error,%” and, without a pump in the profile, “Pulses per liter”. Wilger flow meters: red 8900, green 15500, blue 3400 pulses per liter.
• Electric motors, “Precise” mode — “Holes in disk”, for any motor in the group
• Electric motors, mass dosing — for each motor check “Weight, gr” divided by “Rotations” against the roller specification. The mass calibration fills both in; see “Calibration” in the “Sensor settings” chapter.

The four states of a section

On the diagram each section shows two independent things: whether the monitor watches it, and whether the machine applies through it.

Control	Application	What it means
off	on	Sowing, but nobody is checking this row.
off	off	The section is out of the work altogether.
on	off	Tramline: the row is deliberately not sowing and the monitor knows it.
on	on	Normal work.

Starting to move

1. Put the implement into the working position.
2. Row-crop planters: fill the dispenser disks — main menu, “Fill the disks with seeds”. Without it the first metres of every row are empty.
3. Grain drills: nothing to start. The metering motors sit in automatic rate mode and begin turning of their own accord as soon as the application control starts — which is the moment you move off. Move away briskly all the same: the rotor cells have to fill before the first metres are sown at the target rate.
4. Drive.

One short beep	The product application control has started. From now on the machine is being watched.
Three short beeps	The control has stopped.
Three short beeps every 5 seconds while driving	You are moving with the control locked by hand, or with the implement in the transport position. Nothing is being watched.

Automatic alarm level

On grain drills in “Flow” or “Hybrid” mode, let the panel find the alarm level itself instead of guessing it: hold “BACK” on the home screen before moving off. A double tap on the screen does the same.

The numbers on the diagrams are replaced by a flashing AUTO until the machine has driven enough to measure.

While working

Watch four things: the speed against the tractor, the fan and the pressure inside their range, the actual rate against the target, and that no sensor is alarming.

Table screen	How each section is doing right now.
Statistics screen	How the whole field has gone.

If the speed sensor fails

Switch on speed simulation in the sensor settings and drive on the simulated speed. In that state you control the application by hand: the manual lock, switched with a long press of “HOME” on the home screen. While it is on, the hand icon shows at the right edge and the speed reads zero.

12Filling the disks with seeds

Why the disks have to be filled

When the dispenser disks are driven by electric motors, they stand empty until the motors are switched on. Drive off with empty disks and the first metres of every row are sown with nothing: the disk has to pick up seeds and carry them round to the drop point first.

Filling turns the disks while the machine is standing still, so that seeding starts from the first metre.

Running the operation

1. On the home screen press the “MENU” button.
2. Select the “Fill the disks with seeds” item and press the “MENU” button.
3. The monitor asks for confirmation. Touch Yes on the screen. No, or the “BACK” button, cancels.

What the monitor does

The monitor takes the dispenser motors under its own control and turns each disk at 4 rpm of the driven shaft until the seed sensor belonging to that motor registers the first seed.

If no seed is registered within 1.25 revolutions of the shaft — about 19 seconds — that motor is stopped and marked as failed. A motor that is already in an alarm state is marked as failed straight away, without waiting.

Up to eight motors run at the same time. On a machine with more motors the rest wait their turn.

Reading the screen

Each dispenser motor is shown as a numbered tile along the top of the screen. The colour of the tile is its state.

Tile	State
dark grey	The motor is waiting its turn. Only eight motors run at once.
yellow	The motor is running, the disk is turning.
green	Done: the seed sensor registered a seed, the disk is filled.
dark red	Failed. The disk could not be filled. The letters under the number say why — see below.

Letters on a failed tile

The colour of the letter matters as much as the letter itself: red means a fault, white means removed from control.

Letter	Meaning
m red	A fault of the seed dispenser electric motor was detected during the operation.
m white	The motor is removed from control and cannot perform the operation.
g red	The seed sensor registered no seed at all while the disk was turning.
s red	A fault of the seed sensor was detected during the operation.
s white	The seed sensor is removed from control.

Finishing and aborting

When every motor has finished, the monitor gives three short beeps and displays “Operation complete.”; the button changes to Close. Touch it, or press the “BACK” button, to return to the home screen.

To stop the operation before it finishes, touch Cancel or press “BACK” — the motors stop at once and the monitor hands their control back to the seeding logic.

13Tramline rhythm settings

What you are setting

A tramline is the lane the sprayer will drive in later. You make it now, while sowing, by shutting off one or two sections on certain bouts so that nothing is planted where the wheels will go.

Which bouts those are depends on the width of your drill against the width of the sprayer. That pattern, repeating across the field, is the rhythm.

Example. A 6-metre drill and an 18-metre sprayer: every third bout must carry the lane, so the rhythm is three bouts long and the cut-off happens on one of them. The panel counts the bouts for you and shuts the sections off on the right one.

What the panel allows

Rhythms stored	Three. One is active at a time. Keep the patterns of the machines you work with and switch between them instead of setting up again.
Actuators in one rhythm	Four.
Cut-off bouts per actuator	Four. One actuator can cut off on up to four different bouts of the same rhythm.
Bouts in a rhythm	At least one.

Setting it up

1	MENU → Settings → Tramline. Set the Tramline item to Yes.
2	Open Tramline rhythm settings.
3	Choose the rhythm number with PLUS / MINUS, then MENU → Select. The word Active appears beside the number — without it the rhythm is stored but not in use.
4	Set the number of bouts in the rhythm.
5	Add an actuator: choose its number, then the bout on which it must cut the flow off.
6	Add more cut-off bouts for the same actuator if the pattern needs them — up to four.
7	BACK to the home screen. The rhythm indicator now shows the current bout above and the total below.

What a finished rhythm looks like

The two pictures below were made on a machine set up this way: forty-eight seed sensors, four dry fertiliser sensors, two tramline actuators, markers and a work position sensor, with a rhythm of three bouts in which actuator 1 shuts off on bout 1.

Moving to the next bout

The bout number can change by itself, or you can change it by hand. The menu is opened by a short press of “BACK” on the home screen.

Automatic

The panel can only switch bouts automatically if it has something to tell it that a bout has ended:

Markers in the profile	At least one marker sensor must be under control and answering. The change of the marker position ends the bout.
No markers	The implement position sensor must be under control and answering. Raising the implement out of work ends the bout.
Neither	Automatic switching is impossible. The menu offers only Next bout, by hand.

On top of that, the Auto switching parameter must be set to Yes, and the machine must actually have been applying and then stopped. All of it together — otherwise the bout stays where it is.

By hand

Select Next bout in the same menu and press MENU. Do it at every turn, and check the indicator on the home screen before starting the pass — the number above is the current bout, the number below is the total.

14Alarms and error codes

This chapter lists every alarm the Hectare ONE can show, what causes it and what to do. The alarms are grouped by the device that raises them. The text in the left column is exactly what stands on the screen — look for the words you see, not for a description of them.

When the monitor raises an alarm

A fault is not reported the moment it appears. The monitor waits: the condition must hold continuously for the time set in “Alarm delay” before the alarm window is shown.

Setting	Value
Where it is set	“Settings” menu of the home screen, item “Alarm delay”. Available at the Operator access level.
Range	2 to 20 seconds, in steps of 1 second.
Default	3 seconds. A value outside the permitted range is reset to the default automatically.

Two cases behave differently:

• Loss of communication is counted in polling attempts, not in seconds. The alarm appears after three consecutive failed polls of the device.
• Immediately after a sensor has been set up, alarms of that sensor are not processed at all for a short blocking period. This prevents a burst of alarms while a device is being configured.

How to read the tables

• Alarm text — the message displayed on the screen, quoted exactly. Where the message occupies two lines on the monitor, it is shown here on two lines.
• Description and troubleshooting — the cause of the message and the sequence of the operator’s actions.
• The red band at the top of the window says FAILURE! on every alarm, whatever the fault is. It is the title of the window, not the fault. The fault is the text under it.
• Two ways to close it. Touch the red Close button in the window, or press HOME, which is lit while the window is open; the other six buttons are dark. One touch or press closes one alarm, and the next in the queue appears. A long press of HOME closes every open window at once and returns to the home screen. The alarms of the panel itself carry the line “HOME - close message” in their text; the alarms of the sensors do not.

Any device: communication and device type

Alarm text	Description and troubleshooting
Connection lost	The monitor has received no answer from the device in three consecutive polls. This applies to sensors, actuators, controllers and the input device alike. • Check that the device is connected to the network. • Check the power supply. It must comply with the parameters specified in the device passport. • Check the cable and the connector of the device.
Wrong device type!	A device of another type has been detected at the address of a device of one type. The cause may be an incorrect setting of the system profile or the configuration of the device itself. • To solve this problem, contact the service support.

Rotation speed: fan and dispenser shaft

Alarm text	Description and troubleshooting
Low speed of rotation or High speed of rotation	The rotation speed of the fan or of the dispenser shaft is below or above the allowable one. The same two messages are used for both devices — the name of the device in the alarm window tells you which one it is. • Check the monitored component. • Check the sensor settings. • Check that the sensor is serviceable. • For the dispenser sensor, check that the movement speed shown on the monitor corresponds to the actual one. • For the dispenser sensor, carry out the calibration.
No rotation	There is no rotation of the dispenser shaft. Raised by the dispenser shaft sensor only. • Check the monitored component. • Check the sensor settings. • Check that the sensor is serviceable.

Hopper

Alarm text	Description and troubleshooting
Hopper empty	The level of the seed material in the hopper is very low. Refilling is required. • Check the filling of the hopper. • If the level of the seed material is above the mounting level of the sensor, check that the sensor is serviceable.

If this does not help, metering rollers of a different size have to be selected.

Access level

Alarm text	Description and troubleshooting
User is Agronomist! Alarms will not be shown!	The system has detected that the condition for the control of the product application is met while the “Agronomist” access level is activated. This message is displayed only once for the whole time of work with this access level. • For normal operation of the system, set the “Operator” access level in the settings.

Travel speed sensor

Alarm text	Description and troubleshooting
Speed sensor #1 failed or Speed sensor #2 failed	The alarm is registered only when the use of two movement speed sensors is selected in the settings of the system profile but the system registers movement from only one of them. • Check that the speed sensors are serviceable and eliminate the faults found. • Change the system profile so that only one movement speed sensor is used.
Error in settings of Min/Max	The minimum and maximum travel speed set for the speed sensor contradict each other, so the monitor cannot decide whether the current speed is admissible. • Check the “Min speed, km/h” and “Max speed, km/h” parameters in the settings of the movement speed sensor. The minimum must be below the maximum.

Dispenser electric motor controller

Alarm text	Description and troubleshooting
Motor jammed!	The controller of the electric motor does not register rotation when the electric motor should be running. • Check that the rotation sensor of the electric motor is serviceable, as well as its connection to the controller. Pay attention to the condition of the cable and of the connector. • Check that the metering mechanism is serviceable.
FAILURE	The controller of the electric motor has detected an atypical fault that requires the intervention of the service support. • To determine the error code, go to the “View sensors status” screen from the context menu of the faulty electric motor. The fault code will be given in the “Last fault” line. • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Short circuit	A short circuit has been detected. • Check the quality of the cable connection (the integrity of the cables and of the connector). • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Over current	An excess of current has been detected. • Check the quality of the cable connection (the integrity of the cables and of the connector). • Check the electric motor and the seeding mechanism for jamming. • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Under voltage	The supply voltage of the electric motor is below the allowable one. Operation of the electric motor is impossible. • Check the supply voltage. If the supply voltage is below the allowable one: • Make sure that the alternator is serviceable. • Check the tension of the alternator belts. • Check that the connection is correct. The power harness must be securely connected to the battery or to the alternator terminals in accordance with the required supply voltage. • Check the quality of the cable connection (a reliable electrical contact). If the supply voltage is in order: • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Over voltage	The supply voltage of the electric motor is above the allowable one. Operation of the electric motor is impossible. • Check the supply voltage. If the supply voltage is above the allowable one: • Make sure that the alternator is serviceable. • Check that the connection is correct. The power harness must be securely connected to the battery or to the alternator terminals in accordance with the required supply voltage. • Check the quality of the cable connection (a reliable electrical contact). If the supply voltage is in order: • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Over temperature	The electric motor has overheated. • Cooling of the electric motor is required. • Check that the controller of the electric motor is serviceable by replacing it with a serviceable one.
Device in bootloader!	The controller has stayed in its firmware update mode and is not running its working program. It cannot drive the motor in this state. • Switch the power off and on again. • If the message returns, the firmware update of the controller has not been completed. Contact the service support.

Liquid fertilizer pump controller

Alarm text	Description and troubleshooting
High pressure	The value of the measured liquid pressure is greater than the allowable one. • Reduce the travel speed. • In the settings of the pump controller, increase the value of the “Max pressure, Bar” parameter.
Pressure sensor failure!	The analogue signal from the sensor has gone substantially beyond the limits of the 4–20 mA working range. • Check the connection of the sensor to the controller. Pay attention to the integrity of the cable and of the connector. • Check that the sensor is serviceable. If it has failed, replace it with a new one.
Rate low	The liquid fertilizer pump controller cannot reach the set rate. • Check the readings of the movement speed sensor. The speed value must correspond to the actual travel speed and be relatively stable. • If the working load of the electric pump is more than 90%, try to travel more slowly. • If the working load of the electric pump is less than 90% or the value fluctuates strongly, increase the value of the “Product rate error,%” parameter in the “Settings” menu of the home screen. • Check that the pump is serviceable.
Rate high	The liquid fertilizer pump controller applies more than the set rate. • Check the readings of the movement speed sensor. The speed value must correspond to the actual travel speed and be relatively stable. • If the working load of the electric pump is less than 10%, try to travel faster. • If the working load of the electric pump is more than 10% or the value fluctuates strongly, increase the value of the “Product rate error,%” parameter in the “Settings” menu of the home screen. • Check that the pump is serviceable.

Reading the electric motor fault code

When the FAILURE alarm appears on an electric motor, the controller also records a numeric code. Read it out like this:

1. On the home screen, open the context menu of the faulty electric motor.
2. Go to the “View sensors status” screen.
3. Find the “Last fault” line.

The code says what the controller detected. Quote it to the service support together with the number of the motor. The table below decodes it; the same code is shown as Error code on the Registers-1 page of the Motors screen.

The fault codes

The panel shows only the number. The descriptions are those of the motor controller itself.

Command and parameter errors — the controller refused something the panel asked for:

Code	Description
-250	Invalid command
-251	Unexpected command
-252	Invalid command syntax
-253	Invalid command arguments
-260	Invalid number of arguments
-261	Specified index is greater than FFFFh
-262	Specified sub-index is greater than FFh
-300	Parameter does not exist
-301	Memory write operation failed
-302	Restore operation failed
-306	Parameter cannot be written
-307	Parameter cannot be read
-308	Parameter value out of range
-316	Version of the stored parameter set does not match the firmware version

15System settings

Access levels

The system has three levels. After every power-on the panel starts at the lowest one.

Level	What it allows
Operator	Everyday work. Some parameters cannot be changed and the statistics cannot be reset without a PIN.
Agronomist	Resetting the statistics, the seeding machine parameters, the rate error, and the rest of the commissioning settings.
Service	The profile, and the “Reset to defaults” items. Used by the service department only.

Switching the level

1. On the home screen press “MENU” — the home screen menu opens.
2. Select “Settings” and press “MENU”.
3. Select the “User” item and choose the level with “PLUS” / “MINUS”.
4. Press “MENU”. Going up a level asks for the PIN code; going down does not.

The PIN is different for every panel and is derived from the device code shown on the PIN entry screen. Take it from the device passport or from technical support.

Checking the profile

The profile tells the panel which devices, and how many of them, are in the system. A panel usually arrives with the profile already set. Check it before setting anything else.

Where to look: Settings → User → Service level, then back to the home screen menu → “Service” → “Profile”.

Then check the devices themselves on the home screen:

• No “Connection lost” alarm a few seconds after start — the panel has found everything the profile declares.
• No white indicators with an exclamation mark — nothing is left out of control.
• No red indicators with an “X” — everything answers.

Taking a sensor into control

1. On the home screen hold “MENU” for a few seconds — the panel enters the sensor setup mode.
2. Step to the sensor with “UP” / “DOWN”.
3. Press “PLUS” to take it into control, “MINUS” to take it out.
4. Confirm in the window that appears.
5. Leave with “BACK”. Repeat on the “Actuators” screen if the profile has actuators or electric motors.

The profile parameters

What can be set, and within what limits

Parameter	Range
Seed sensors	2 … 120. The menu lets you enter 1, but such a profile is rejected when it is saved.
Fertilizer sensors	0 … 60, and seed + fertilizer together not more than 120.
Liquid fert. flow sensors	0 … 60
Hoppers	0 … 9
Dispensers	0 … 9
Speed	No / Panel / Input device / Input device (2) — at most one speed sensor either way.
Fans	0 … 2
Pressure sensors	0 … 3
Implement position sensor	No / Yes
Markers	No / One / Both
Diesel generator sensors	Battery charge, oil pressure, ignition, low fuel, air filter — No / Yes each.
Seed dispenser electric motors	0 … 60
Fertilizer dispenser electric motors	0 … 30, and both motor groups together not more than 60.
Tramline actuators	0 … 4
Liquid fertilizer pump controller	0 … 1

When the panel refuses a profile

The panel checks the whole profile, not the single item being changed. It rejects a profile when:

• the hopper, dispenser and diesel-generator sensors together come to more than 12;
• they come to more than 10 while the pressure and fan sensors together come to more than four;
• the pressure and fan sensors together come to more than five;
• there are fertilizer motors but no seed motors, or fertilizer motors but no fertilizer sensors;
• there are electric motors or a liquid fertilizer pump but no speed sensor;
• liquid fertilizer valves and a pump controller are declared at the same time.

Saving and loading

For the current profile the panel can save all the settings and restore them later — useful for trying something out. Both items are in the “Profile” menu: “Save settings” and “Load settings”.

With an SD card in the slot it is better to use “Save to SD-card” and “Load from SD-card”: a profile saved that way carries its settings with it, so one panel can serve several implements.

The “Settings” menu

Item	Range	Level
Brightness, %	0 … 100, in steps of 10. At 0 the item reads AUTO and the panel sets the backlight itself from its light sensor, brightening quickly and dimming slowly. Any other value fixes the backlight at that level.	Operator
Volume	0 … 100, in steps of 10	Operator
Language	the installed languages	Operator
Buttons sound	No / Yes	Operator
Alarm delay	2 … 20 s	Operator
Rate error,%	3 … 20 %	Agronomist
Seeding machine parameters	submenu	Agronomist

Seeding machine parameters

Width, cm — the working width of the implement. The processed area is calculated from it, so it must be entered. Numbers are typed on the keypad: the digits, the backspace at the top right, OK to accept, “BACK” to leave the old value.

Mode of seeding and Mode of fertilizers — three modes each:

• Flow — seeds per second. For grain seeders.
• Hybrid — seeds per metre. Recommended for grain seeders.
• Precise — seeds per metre, and skips and doubles are counted as well. For row-crop seeders.

Mode of liquid fertilizer — Flow (litres per minute) or By area (litres per hectare). Shown only when there is no liquid fertilizer pump controller in the profile — with a controller the panel decides the mode itself.

Actuators to sensors mapping — which section sensors belong to which actuator or electric motor, so that they switch to tramline monitoring when that actuator shuts its sections off. A mapping is a range: a start number and an end number; equal numbers mean a single section. Up to four ranges may be attached to one actuator.

Tramline — the rhythms of the tramline. A submenu of its own.

The rhythms themselves are described in the chapter “Tramline rhythm settings”.

Speed calibration and Dispenser calibration — the two calibrations that need the machine to move. Both procedures are in “Sensor settings” → “Calibration”. Dispenser calibration carries a number beside it: the dispenser to calibrate, or 0 for all of them at once.

Reset to defaults — returns this menu to the factory values. Service level only.

Diagram settings

There are three of these menus — one for the seed sensors, one for the dry fertilizer, one for the liquid fertilizer. Each appears only when its own diagram is not in the “Flow” mode and its own sensors are in the profile.

Item	What it does
Skips & Doubles	Shows the skip and double bars over the last stretch of the path. “Precise” mode only.
Grid	No — only the rate line; Partial — only the tolerance limits; Full — both.
Scale S&D, %	The height of the skip and double bars, 5 … 50 % in steps of 5. “Precise” mode only.
Reset to defaults	Visible at the Service level only.

Change Date & Time

Set the fields, then choose “Set” and press “MENU”. “BACK” leaves them unchanged.

16Sensor settings

Reaching a sensor

1. On the home screen hold “MENU” for a few seconds. The panel enters the sensor setting mode and the selected sensor is drawn inside a white rectangle.
2. “UP” / “DOWN” move from sensor to sensor. “PLUS” takes the selected one into control, “MINUS” takes it out.
3. “MENU” opens the context menu of the selected sensor.
4. “BACK” leaves the mode.

A sensor tile can also be held down directly to open the same context menu.

What every context menu has

Information	Opens the status screen of this sensor.
Disable control / Enable control	Takes the sensor out of monitoring, or back into it. Asked for confirmation the first time in a session.
Reset to defaults	Returns this sensor’s parameters to the factory values. Service level only.

Between them stand the parameters of that particular sensor. Which of them are shown depends on the access level — the tables below give the level of each.

The status screen

Reached through “Information”. It shows what the panel knows about one sensor.

Button	Action
PLUS / MINUS	Next / previous sensor — the screen stays open.
UP / DOWN	Step through the active alarms of this sensor.
MENU	The context menu of this sensor.
BACK	Back to the sensor selection.

The screen carries: the channel (which sensor of the group), the address it answers on, its type and number, how it is connected, the state of the communication, a block of figures particular to that sensor type, and the list of active alarms.

Normal	The sensor answers.
Not controlled	Neither the communication nor anything else is being watched.
No connection	The sensor does not answer. Shown in red.
Wrong device type!	Something answers at this address, but it is not the kind of device the profile expects. Shown in red.
IMITATION	Only on the speed sensor: the speed is being simulated, not measured. Shown in yellow.

What each kind of sensor adds

Below the common lines every kind of sensor shows its own figures. They are drawn only while the sensor is under control, answers, and is of the expected kind.

Sensor	What the block shows
Speed sensor	The pulse frequency as F= in Hz; with two speed sensors, F1= and F2=. Under it the two speed limits, Min speed, km/h and Max speed, km/h. On a machine that doses a product by weight with electric motors the limits are the ones the motors can hold, narrowed by the two settings; a limit the settings cannot meet is written in red as an inequality. Without such motors a limit set to zero is shown as —-, that is, switched off.
Hopper sensor	Pin: and the level on the input, “0” or “1”.
Dispenser shaft sensor	The pulse frequency as F= in Hz, to three decimals.
Fan sensor	The pulse frequency as F= in Hz.
Pressure sensor	The pressure as P= in kPa.
Seed sensor, dry fertilizer sensor	Status: and one of eight states, listed below.
Liquid fertilizer flow sensor	Status: Working, or Working:Tramline while the section is in the tramline mode; under it Flow= and the rate in L/min.
Implement position sensor	Position: Working or Position: Transporting, and Pin: with the level on the input.
Ignition, oil pressure, battery charge, fuel level, air filter	Pin: and the level on the input, “0” or “1”.
Marker sensor	No block of its own: only the common lines.
Tramline actuator	Status: Pulled in, Pulled out, Working while the shutter is moving, or Unknown.
Dispenser electric motor	Status: Working, or Faulty while any alarm of the motor is active; then Last fault: with the controller’s numeric code, if there has been one. A universal controller adds the line IN1[ ] IN2[ ] IN3[ ] with the levels on its three inputs.
Liquid fertilizer pump controller	Status: Working or Faulty. With a fault, Last fault: and the code. Without one, three lines: Flow= in L/min, Load= in per cent, and the pressure sensor of the line — Pressure sensor: No if the machine has none, otherwise Pressure sensor= in Bar with the raw signal in mA in brackets; dashes stand for a value the controller cannot give.

The eight states of a seed or fertilizer sensor:

Status	Meaning
Working	Normal.
Working:Tramline	Normal; the sensor has been switched into the tramline control mode for the current bout.
Configuring	The sensor has received new settings from the panel and is applying them.
Calibration in progress	The sensor is running its initial calibration. It takes a few seconds.
Clogged	The infrared emitter of the optical channel is blocked, most likely by a blocked seed tube. Shown in red.
Light struck	Too much sunlight falls into the optical channel; the sensor may miscount. Shown in red.
Faulty	The sensor has failed and needs to be replaced. Shown in red.
Unknown	Another fault that cannot be identified. Shown in red.

At the bottom of the screen the active alarms of this sensor are listed one at a time, as Alarm N from M in red followed by the name of the alarm; “UP” and “DOWN” step through them.

Calibration

Four calibrations exist, and they are not variants of one procedure. Each writes different parameters, each is reached a different way, and two of them need the machine to move.

What it puts right	Where it lives	Level	Machine
Movement speed — the pulse count the speed sensor gives over a known distance	“Settings” → “Seeding machine parameters” → “Speed calibration”	Agronomist	drives 100 m
Dispenser rotation — “Wheel, pulses” against “Dispenser pulses”	“Settings” → “Seeding machine parameters” → “Dispenser calibration”	Agronomist	wheel and dispenser shaft turned together
Dispenser mass — “Weight, gr” and “Weight, pulses”	context menu of the dispenser sensor	Operator	standing still
Metering roller mass — “Weight, gr” and “Rotations” of one electric motor	context menu of the dispenser electric motor	Operator	standing still

Speed calibration

Everything the panel counts — area, rates, deviations — is derived from distance travelled. A speed sensor that is out by a tenth makes every other figure on the panel wrong by a tenth.

Before starting, set “Pulses” and “Diameter, cm” for the sensor. The calibration corrects the pulse figure; it cannot invent it.

The panel refuses to start and shows a red-headed box if:

“No speed sensor”	The profile carries no speed sensor.
“Connection lost with the sensor! Calibration canceled!”	The sensor does not answer.
“Sensor not controlled! Calibration canceled!”	The sensor has been taken out of monitoring.

The procedure.

1. Mark out 100 m on the ground and put the machine at the start.
2. Open “Settings” → “Seeding machine parameters” → “Speed calibration”. The panel shows “Pass 100m and press STOP” with a single “STOP” button.
3. Drive the marked distance and stop.
4. Press “STOP”.

The distance is fixed at 100 m in this firmware. The panel does not ask for it.

On success the panel shows “Done” and closes the box by itself. If the counter did not move it shows “FAILURE! The tractor did not move!” — which means the sensor gave nothing at all, not that it was inaccurate. Closing the box any other way gives “Calibration canceled!” and changes nothing.

Dispenser calibration — rotation

This one teaches the panel how many dispenser shaft pulses belong to one wheel pulse, so that it can tell a stopped shaft from a moving machine. It is the basis of “Rotation speed control”.

It can be run for one dispenser or for all of them at once — the menu item carries the number, and 0 means all.

Both the speed sensor and every dispenser taking part must be under control and answering. If any of them is not, the calibration ends with “Sensor not controlled! Calibration canceled!” or “Connection lost with the sensor! Calibration canceled!”.

The procedure.

1. Open “Settings” → “Seeding machine parameters” → “Dispenser calibration” and set the dispenser number, or 0 for all.
2. The panel shows “Calibration” and a progress bar. Turn the drive wheel and the dispenser shaft together — by hand, or by moving the machine.
3. The bar fills as the counters rise. It reaches 100 % when both the speed sensor and every participating dispenser have given at least 100 pulses. The bar follows whichever is furthest behind, so a dispenser that is not turning holds it at zero.
4. At 100 % the panel beeps once and shows “Stop rotation!”.
5. Stop everything. The panel waits until no counter has changed for two seconds, then writes the result and shows “Done”.

“To abort operation press BACK.” stands at the bottom of both screens and does what it says at any moment.

Dispenser calibration — mass

Reached by holding the dispenser sensor tile and choosing “Dispenser calibration(weight)” from its context menu.

The panel raises itself to Agronomist level for the length of the calibration and puts the level back on exit.

The procedure. The panel spells the steps out on the screen; they are repeated here because the screen has room for the wording but not for the reasoning.

The first screen lists the target rates in kg/ha of the products in use and marks the one this dispenser meters with > and <. Start with “Calibrate dispenser N” (or the “PLUS” key); leave with “Exit” (or “BACK”).

If the dispenser cannot be calibrated, the button is replaced by a red line naming the reason: “Not controlled”, “No connection” or “FAILURE”.

The second screen carries the filling instructions:

1. Weigh the empty container and write down the weight.
2. Fill the hopper with the product.
3. Place the empty container under the dispenser.
4. Start filling the rotor cells by rotating the rotor.
5. When the rotor cells are filled, go to the calibration.

Step 4 matters more than it looks: a rotor whose cells are still empty gives short measure for the first turns, and that error lands in the stored constant. Go on with “Go to calibration” (or “UP”), step back with “Cancel” (or “BACK”).

The third screen is the measurement. It counts “Impulses” and turns a rotor icon as they arrive:

1. Empty the container of product.
2. Place the empty container under the dispenser.
3. Rotate the dispenser rotor, filling the container as much as possible, but not less than 2 kg and not more than 60 kg.
4. Weigh the filled container.

The “Complete” button (or the “MINUS” key) appears only after more than ten pulses have been counted. “Cancel” — or “BACK” — asks “Are you sure?” before throwing the measurement away.

Finish, and the keypad asks for “Enter the difference of the filled and empty container in grams”. The figure must lie between 2000 and 60000 grams; the panel offers 10000. Enter the weighed difference, and the panel stores “Weight, gr” and “Weight, pulses”.

Electric motor calibration — mass

Reached by holding the dispenser electric motor tile and choosing “Dispenser calibration(weight)”.

Entering this calibration puts every electric motor on the machine — seed and fertilizer alike — into manual mode at zero speed. Leaving it puts them all back to automatic rate control. Nothing meters while the calibration is open.

The first screen shows the target rates as above, and under them the dosing speed window the current settings allow: “Product dosage speed limitation:” with “Min speed, km/h” and “Max speed, km/h”. If the minimum has risen above the maximum the block turns red and reads “Can not provide dosage!” — the roller fitted cannot deliver the rate asked of it at any speed, and calibrating will not repair that. Start with “Calibrate electric motor N” or “PLUS”.

The second screen prepares the rotor:

1. Weigh the empty container and write down the weight.
2. Fill the hopper with the product.
3. Place the empty container under the dispenser.
4. Start filling the rotor cells. The dispenser will perform 2 turns.
5. If the rotor cells are filled, go to the calibration.

Here the motor does the turning. “Fill the rotor cells” — or the “MENU” key — runs the shaft at the middle of the motor’s own “Minimum, rpm” and “Maximum, rpm” window, capped at 60 rpm, for exactly two turns of the driven shaft, then stops by itself. “Stop motor” (“BACK”) interrupts it. Repeat until the cells are full. Then “Go to calibration” or “UP”.

The third screen shows “Rotations” to one decimal and waits:

1. Empty the container of product.
2. Place the empty container under the dispenser.
3. Do the calibration. Fill the container as much as possible, but not less than 1 kg and not more than 60 kg.
4. Stop the motor.
5. Weigh the filled container.

“Calibration” — or “MENU” — starts the motor; “Stop motor” or “BACK” stops it. Run and stop as many times as needed: the turn counter keeps running total. “Complete” (or “MINUS”) appears once more than one full turn has been made.

The keypad then asks for the same weight difference, this time between 1000 and 60000 grams. The panel stores “Weight, gr” and “Rotations” for that motor.

The calibration stops itself and reports a failure if the motor stops answering, if the motor raises an alarm, or if ten seconds pass with no pulses from the rotation sensor — the last of these is reported as “No data from rotation sensor”. A jammed or unplugged rotation sensor therefore ends the run rather than quietly recording zero.

Seed sensors and dry fertilizer sensors

Both groups are the same kind of device and share one parameter set. Almost everything here is common to the whole group — only whether the sensor is under control — “Disable control” / “Enable control” in its context menu — and the product application are set per sensor.

The two target rates of this sensor — one for the flow mode, one for the by-area mode — have no menu item: they are set on the home screen with “PLUS” and “MINUS”, like every other target rate.

Liquid fertilizer pump controller

Parameter	Range	Level
Pulses per liter	100 … 10000	Agronomist
Pressure sensor	0 … 2 — which pressure sensor watches the supply line	Agronomist

Button input	0 … 3 — digital input of the motor controller used as a calibration button; 0 = none	Agronomist
Activation signal	0 / 1 — which state of that input counts as pressed	Agronomist

Numerator and denominator together are the gear ratio between the motor and the dispenser shaft.

“Minimum, rpm” and “Maximum, rpm” are not a safety limit but the window the rate controller works inside; the dosing speed window on the calibration screen is calculated from them together with the roller constant. “Button input” and “Activation signal” are described under “Calibration” above.

Maximum, Pa	0 … 10000, in steps of 100	Operator

Marker sensors

Parameter	Range	Level
Connected marker	Left / right	Agronomist
Signal “down”	Which state of the input means the marker is lowered	Agronomist

Hopper, implement position and diesel generator sensors

These are all discrete inputs — they report one of two states and nothing more.

Parameter	Range	Level
Activation signal	Which state of the input is the one worth reporting	Agronomist
Signal delay, sec	How long that state must hold before it counts	Agronomist

The hopper sensor has no parameters of its own at all — its context menu carries only the three common items.

The diesel generator group — battery charge, oil pressure, ignition, low fuel, air filter — are five of these inputs, each switched on separately in the profile.

Tramline actuator

The actuator has no parameter table of its own in the sensor menus: Cutoff position and Switch are set where the actuator is configured. Its rhythm belongs to the chapter “Tramline rhythm settings”, and the assignment of sections to it to “System settings”.

17Device configuration

Before you start

1. Disconnect every sensor from the communication cable connector of the panel.
2. Connect only the one device that is to be given a new address.
3. Switch the panel on. Alarms about lost communication appear — close them all.
4. Raise the access level to Agronomist: home screen → “MENU” → “Settings” → “User” → choose the level with “PLUS” / “MINUS” → “MENU” → enter the PIN.
5. Leave with “BACK”, choose “Service” → “Sensors Configuration”.

The pattern, once

All four menus work the same way, so it is worth reading once.

Item	What it is
Sensor address / Device address	Which device the menu is talking to. Leave it at AUTO and the panel talks to whatever single device answers. Pressing “MENU” on this item starts a search; each further press steps to the next device found.
New address	The address the device is to be given. Set it with “PLUS” / “MINUS”.
Set	Writes it. “Done” means the device accepted it.

Afterwards, every time: disconnect the device and connect it again, then return to the home screen and check that it appears where it should. Then set the access level back to Operator — or simply switch the panel off and on, which does the same.

Seed sensor

The address of a seed sensor can only be changed while the sensor is working normally. A tube sensor is ready as soon as it is connected. An open sensor has to sit on its bracket, or be held so that daylight does not fall into the optical channel — the gap between the two glasses. In direct light the sensor reports a permanent seed flow and does not accept the new address.

New address here is the number of the row, the same number the operator sees under the column on the home screen.

Pressure sensor

The same three items. The panel proposes the correct value for the first pressure sensor by itself, and each further sensor takes the next one — take the numbers from the data sheet of the system, they are not printed here.

HUB8 input device

The HUB8 carries several sensors at once, so its menu is longer: after the device address come the eight channels, in pairs.

Channel N type	What is wired to that channel.
Channel N address	Which sensor of that kind it is — hopper 1, dispenser 2, and so on.

A channel that carries nothing is left as it is. The type and the number together are what makes the sensor appear on the home screen under the right icon.

Tramline actuator

The actuator controller carries three things at once, and each has its own line:

• Actuator — the number of the tramline actuator itself, or No if this controller drives none.
• Input device, channel 1 and channel 2 — the two marker sensors of the bout, or No.

This is why one controller serves an actuator and both markers: they are three separate numbers on one device.

Electric motor controllers

The four kinds of device above are addressed from “Sensors Configuration”. The controllers that drive the metering motors are not: they have their own way in, their own choice of controller kind, and their own parameter set.

MENU → “Service” → “Electric motors”. Service level. The item opens the Motors screen, and each motor’s own menu leads on to its controller.

Choosing the controller kind

Four kinds are supported, and the panel offers them by number:

“1)universal”	The universal controller: two DC channels or one stepper channel on the same board.
“2)DC motor”	A DC motor controller.
“3)STEPPER fw0.006+”	A stepper controller, firmware 0.006 and later.
“4)BGxxCI”	A BG45CI motor with the controller built into it, on the older board.

The panel reads the kind back from the controller itself and opens on the one that answers. Choosing a different kind by hand is how a replacement board is set up, not a way to change what a motor is.

What each kind is given

Every one of these menus ends with “Set”, and “Set” carries a value of its own — the address group, 0 to 3. Nothing is written to the controller until “Set” is entered: the items above it change the numbers the panel is holding, not the ones the controller is running on.

Kind	What it is given
STEPPER	“Pulses” 1 … 8192 — the pulses one turn of the motor shaft produces; “Motor type” from a list; “Set”.
BGxxCI	“Pulses” 1 … 8192; “Set”. Nothing else — the controller carries the rest itself.
DC motor	“Pulses”, “Motor type”, the three regulator terms “PID kP”, “PID kI”, “PID kD” (0 … 65535, read as hundredths), “TURBINA” 0/1, and two speed–time pairs “TIME1”/“SPEED1”, “TIME2”/“SPEED2”; “Set”.
universal	The largest set, split over three menus: “Work mode”, “Inputs setup” and “Parameters”.

The universal controller’s “Parameters” menu holds:

Parameter	Range
“Motor type”	0 … 255, from the controller’s own table
“Pulses”	1 … 8192 per shaft turn
“Acceleration,Ms” / “Deceleration,Ms”	50 … 65535 — the ramp the drive is taken up and down over
“Minimum, rpm” / “Maximum, rpm”	0 … 65535 — the shaft speed window
“PID kP”, “PID kI”, “PID kD”	0 … 65535, hundredths
“!! Temp,*C”	0 … 200 — the temperature the controller alarms at
“I_peak,A” / “I_peak,mS”	the peak current and how long it may be drawn
“I_push,A” / “I_push,Sec”	the breakaway current and its time
“I_hilo,A” / “I_hilo,Sec”	the sustained-current threshold and its time
“Set”	writes all of it, at the chosen address group

Reading a motor controller

The Motors screen is also the diagnostic screen of a controller. It shows, live, what the controller reports about itself:

“Speed” / “Target speed”	What the shaft is doing against what the panel asked for. A gap that does not close is the first sign of a mechanical load the motor cannot carry.
“Error code” / “Act.posit.”	The controller’s own error number, and the position it counts itself at.
“Volt.mot.,mV” / “Volt.elec.,mV”	The voltage at the motor and at the electronics, in millivolts. They differ; a motor voltage far under the electronics voltage means the supply is sagging under load.
“Temperat.,C” / “Current,mA”	The controller’s temperature and the current it is drawing. Compare the current with “I_hilo,A” set for this motor.

Under those four lines the panel draws the controller’s status word — sixteen bits, with a legend naming each:

0  Enable 1  Error  2  Warn.  3  Moving
4  Reach  5  Limit  6  FolErr 7  HomDone
8  Toggle 9  CmdTgl 10 CmdErr 11 StpHalt
12 LimCur 13 LimVel 14 LimPos 15 LimSVel

At the bottom stand the fault counters this motor has collected on the chosen field — they are part of the field statistics, not of the motor:

“Jammed”	The rotor stalled and the controller had to give up or back off.
“Overcurrent”	The current went past its threshold for longer than the threshold’s time.
“Overtemperature”	The controller went over “!! Temp,*C”.
“Disconnects”	The controller stopped answering.
“Other”	Everything else the controller reported.
“In failure”	The distance in metres this motor spent in a fault state.

Each counter is white at zero and red once it is not. A red figure does not mean the motor is faulty now — it means it was, somewhere on this field, and the seed placed there is worth looking at.

Changing a controller’s address

Press “MENU” on the Motors screen. Two items, both Agronomist:

“Change address”	Gives the controller a new address.
“Configuration”	The controller configuration menus described above.

“Change address” opens three items:

1. “Motor address” — the address the controller answers on now. Leave it as found.
2. “New address” — the address it is to take. Take it from the data sheet of the system; the numbers are not printed in this manual.
3. “Set” — writes it.

The rest of the Service menu

“Service” carries fifteen items. Four of them are described above and elsewhere; the rest are listed here so that an engineer knows what he is looking at and, more to the point, what he should leave alone.

Item	Level	What it is
“Profile”	Service	How many of each device the system has. Described in “System settings”.
“Sensors Configuration”	Agronomist	Addressing the four kinds of device — the chapter above.
“Registers”	Debug	A raw register view. Not part of any documented procedure.
“Electric motors”	Service	The motor controllers — the section above.
“Serial number”	Debug	The serial number of the panel, entered once at manufacture.
“Count seeds always”	Agronomist	No / Yes — keep the seed counter running even when the panel would otherwise stop it.
“Enter key”	Agronomist	Enters the licence key that takes the panel out of the demonstration state.
“Set trial”	Service	Starts the demonstration period.
“Trial, hours”	Service	1 … 999 — how long that period lasts.
“Imitation mode”	Service	No / Yes — the panel works from simulated data. See the warning below.
“Display type”	Debug	Which display panel the firmware is driving. Set at manufacture.
“Launch updater”	Service	Restarts the panel into the updater to take firmware from the memory card.

Three further items — the tracker protocol and the two logging switches to the memory card — are present in the firmware but set to be never shown. They cannot be reached from the panel at any access level.

Debug is the fourth access level, above Service. The panel names its four levels “Operator”, “Agronomist”, “Service” and “Debug”. The three items marked Debug above are set at manufacture and have no field procedure behind them.
