Problem Cause Solutions
The seeding shaft does not
rotate when the implement is in
working position!

Seeding shaft is not
switched on.

Forward speed is 0.

No linkage signal.

Switch on the seeding shaft,
the seeding shaft must be
switched on manually one
time at the beginning.

Check the settings for the
speed sensor
– see Point
6.3.4.

Check the speed sensor.

Check the linkage sensor.
A fill level sensor is installed,
but does not transmit!

No signal from the fill level
sensor.

The fill level sensor is
deactivated, see Point
6.3.2.

Adjust the sensitivity of the fill
level sensor (screw on the
rear side).

Reposition the fill level sensor.

Check the plug and cable.
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.

Deactivate the fill level sensor,
see Point 6.3.2.
No speed signal!

Speed signal is not
available on the ISOBUS.

Wrong speed signal was
selected.

Check the settings for the
speed sensor
– see Point
6.3.4.
No linkage signal!

Linkage sensor was not
detected.

There is no linkage signal
issued on the ISOBUS.

Check the signal source.

If external linkage sensors are
equipped, check them.

Magnet sensor: the sensor
and magnet must be precisely
opposite to each other when
in working position or in lifted
position.
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 (Point 6.3.4).
Spread rate in kg/ha or
seeds/m² is not being
displayed!

A valid calibration test
was not performed.

Values were retroactively
changed in the Calibration
test menu.

Perform a calibration test.

Load the seed type again from
the library.
