INDEX

5
The seeding controller has two programs:
1 – A seed counting program using optoelectronic sensors for precision seed drills (maximum 12 rows).
2 – A program including counters to count the area, time, distance and speed.
The device is made up of the following:
- A control unit installed in the tractor, which is used to enter data and control the seed drill. The unit generates
audio and visual alarms in the event of problems.
- Cable form connecting the control unit and the sensors.
- Optoelectronic sensors fitted on each seeding element.
- A rotation sensor installed on its support on the seed drill rotating shaft.
1 – Using the controller to count the seed with the optoelectronic sensors
When seed goes past the optoelectronic sensor, a pulse is sent to the computer, which determines and displays the
number of seeds per hectare for each row. If the value is less than 15% of the setting entered by the user, the
controller generates an audio and visual alarm. If the difference is less than 15%, there is no alarm.
While sowing seed with a diameter of less than 3 mm (e.g. rape seed), reduce the alarm limit so that the control unit
only monitors that seed is being delivered (no counting facility in this case).
2 – Using the controller for other counting functions
When the counter is displayed, an arrow is displayed above the corresponding symbol.
Counters are available for the following:
- seeded area and total area with the tool in the working position
- speed
- working time
- output per hectare
- distance.

ASSEMBLY INSTRUCTIONS
- 1 – Computer.
The computer is to be fitted with its support in the field of vision of the driver.
Keep a distance of at least one metre between the computer and transmitters (CB or other) or transmission antennas.
- 2 – 12 volt connection to the battery.
The computer must be connected directly to the battery. No other device may share this connection.
Protect the power supply with a 25-Amp fuse.
- 3 – Colours of connections
BROWN = 12V
BLUE = earth
- 4 – Cable form.
The cable form and sensors are installed in the factory.
For subsequent modifications, see page 25 for the wiring diagram of the unit.
- 5 – Optoelectronic sensors
The optoelectronic sensors are fitted on the seeding elements. The connection is made via a 4-pin connector.
When seen from behind, the row to the far left is row 1.
Wire colours:
WHITE = earth
BROWN = + 12 volts
GREEN = signal
YELLOW = signal for shunt connector
IMPORTANT:
- While modifying a seed drill, make sure to replace any BNN0082 ejectors with the BNB0083 model (different
ejection height) supplied with the control unit cell.
- Make sure that the seal is in place on the connector of the optoelectronic sensor. Keep the cables safe from
friction and other harmful influences.
- Handle the cell support with care. Any deformation would misalign the cells and lead to system
malfunctioning.
Ejector

- 6 – Rotation sensor.
The magnet is fitted on the hexagonal drive bar of the seed drill and must be
opposite the sensor. The sensor must be fitted at a distance of about 5 to 10
mm from the magnet (diagram opposite)
- 7 – Modifying the number of rows.
Proceed as follows to modify the seed drill, say from 8 rows to 6 rows:
- stop the control unit
- disconnect the optoelectronic sensor (4-pin connector) from the rows to
be removed
- replace the connector of the optoelectronic sensor with a shunt connector
(see page 25)
- on the control unit, change the number of rows, working width and
programming.
- 8 – Adding rows to the seed drill.
In order to add rows to an existing seed drill, you can add cells to the form, in accordance with instructions NT0006500
(attached).
PRECAUTIONS:
PRECAUTIONS FOR USE.
This devices is intended for farming machinery only.
Other uses are not covered by the guarantee.
ELECTRICAL PRECAUTIONS.
Before starting to work on the electronic system of the tractor or seed drill, first disconnect the seeding control unit
from the battery.
That is also indispensable during welding work on the tractor or tool.

UTILISATION
KEY DESCRIPTION.
The keys are of three colours:
Red keys: programming
White keys: information (value display)
Black keys: On/Off or modifying the number of rows while working
1 – Starting up the device: Start key
Use keys and to start up the device and switch if off.
When the device is turned on, the software version is displayed briefly. The unit then goes through the set-up procedure
and automatically displays the last function used before the unit was switched off.
If the power supply voltage drops below 9 volts, the device is turned off automatically.
If there is an electronic fault, the unit displays either HALP 00 or HALP 88
In that case, it must be returned for repairs.
2 – Programming the device: Programming keys
Keys “ +/- ”
Used to change the values of the programmed data.
For the electronic control box to calculate the various values displayed, the following data are required.
- pulses over 100 metres
- working width
- number of rows

9
Working width key
- press the « working width » key
- display the value with keys « + / - »
- press Enter to save or validate
Then check the working width by pressing
« the working width » key once again :
Example:
You have a 6-row drill with 0.45 m spacing, i.e. a working width of 2.70 m,
- press the working width key
- display 2.70 m using key + or -
- press Enter to validate

10
Pulses over 100 metres key
This key is used to enter the number of pulses the rotation sensor indicates over a distance of 100 metres on the
computer.
There are two ways of entering this information:
1 ) The theoretical value of the pulses over 100 metres is 64 for our seed drills
-press the Pulses over 100 m key
- display the value using keys « + or - »
- press « Enter » to save
2) You want maximum precision in all land (soft, light etc.):
- reset the number of rows to zero (see page 11)
- measure an accurate distance of 100 metres and mark it out.
- place the machine opposite the first marker.
- press the Pulses over 100 mm key and at the same time.
- cover the 100-metre distance at the normal working speed.
- press Enter when you go past the 2nd marker to save the setting.
