Problem
Cause
Solutions
Fill level sensor is
constantly transmitting.
 Poor sensor setting.
 Poor sensor position.
 Adjust the sensitivity of the fill level
sensor (screw on the rear side).
 Reposition the fill level sensor.
No speed signal.
 Speed sensor was not
detected.
 Wrong speed sensor was
selected.
 Y cable (splitter cable)
incorrectly connected.
 Y cable (splitter cable)
defective.
 Check the settings for the speed
sensor, see chapters 8.4 – 8.7.
 Connect the Y cable properly, pay
attention to the markings/labels.
 Test without the Y cable (only
connect the speed sensor).
No linkage signal.
 Linkage sensor is not
detected.
 There is no linkage signal
emitted on the 7-pin signal
plug of the tractor.
 Y cable (splitter cable)
incorrectly connected.
 Y cable (splitter cable)
defective.
 Magnet sensor:
sensor/magnet incorrectly
installed.
 Check the linkage sensor.
 Connect the Y cable properly, pay
attention to the markings/labels.
 Test without the Y cable (only
connect the linkage sensor).
 Magnet sensor: the sensor and
magnet must be precisely opposite
to each other when in working
position or in lifted position.
The control box cannot
be switched on.
 Power cable is not properly
connected.
 No supply voltage.
 Defective fuse.
 Check the plugs.
 Check the polarity of the power
cable (pin 15/30 12 V +, pin 31
ground, pin 82 ignition on +).
 Switch on the ignition.
 Check the battery.
 Replace the fuse.
The control box is
switched off when the
motors are switched on.
 Battery is weak, supply
voltage collapses.
 Voltage drop due to poor
contact.
 Check the battery voltage.
 Check the contacts of the plugs.
 Check the power supply cable.
A forward speed of
0.0 km/h is displayed or
it keeps jumping back
to 0.0 km/h.
 Wrong speed signal detected
or selected.
 Check the speed sensor settings,
see chapter 8.4 – 8.7. If all of the
settings are on AUTO, then set the
first DIN 9684-1 signal to NO.
Spread rate in kg/ha or
grains/m² is not being
displayed.
 A valid calibration test was
not performed.
 Value was retroactively
changed in the Calibration
test menu.
 Perform a calibration test.
Spread rate is too high
or too low.
 Wrong speed.
 Linkage sensor switches
during operation.
 Seed properties have
changed.
 Check the hectare counter and
speed.
 Calibrate the speed sensor (not
required for GPSa sensor).
 Check the linkage sensor.
 Perform a calibration test.
 Reduce the fan speed for the
hydraulic fan.
