 Contact customer service.
◯
X No motor speed (pump)!
 The flow sensor connection
(blue) is not or not properly
connected.
 The pump is running at its
minimum and cannot reach the
spread rate.
 Check the cabling.
 Reduce the speed.
 Increase the spread rate.
 Smaller nozzles.
 Fewer outlets.
◯
X Ground wheel not OK!
The control box is not receiving
any signals from the speed
sensor.
 Check the ground wheel,
sensor, cables and plugs.
 If a defects cannot be found
on the ground wheel that
explain the malfunction,
please contact customer

◯
X Speed too low (fan)!
 The speed of the hydraulic
fan is below the lower limit (set
in Point 5.10).
 The pulses/revolution
parameter is incorrectly set.
 Switch on the hydraulic fan.
 Increase the speed of the
hydraulic fan.
 Set the pulses/revolution
parameter correctly, see
Point 5.10.
 A speed sensor is not

 Wrong linkage signal.
 Invert the tractor linkage signal, see
chapter 8.9.
 Reposition the linkage sensor.
Seeding shaft does not
rotate when the
implement is in working
position.
 Seeding shaft is not switched
on.
 Forward speed is zero.
 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 chapters 8.4 – 8.7.
 Check the speed sensor.
 Check the linkage sensor.
The fill level sensor is
installed, but is not
transmitting.
 No signal from the fill level
sensor.
 Adjust the sensitivity of the fill level
sensor (screw on the rear side).
 Reposition the fill level sensor.
 Check the plug and cable.
