The forage presses strongly
against the tailgate.
The floor conveyor can still
be switched on. The light
field (100%) will not flash.
• Check reed switch (14 – wagon full)
• Check the plug connections according to the circuit diagram
The knife frame opens too
far (up to the hydraulic
cylinders’ limit stop).
The cutterbar open indicato
light (M) will not light up.
• Check reed switch (10 – knife frame)
• Check the plug connections according to the circuit diagram.
The faults
• Pick-up up/down
• Articulated drawbar
up/down
• Knife frame open/close
• Tailgate open/close
can be checked as follows.
Manually actuate the corresponding solenoid(s).
Find out if the fault is in the hydraulic or in the electric system. Hydraulic
fault = see „Hydraulic System“ chapter.
Electrical fault:
• Check the plug connections according to the circuit diagram
• Check the coil and the iron core of the corresponding solenoid.
Values = see key to circuit diagram
• Check voltage on solenoid without and then with a consumer
connected (voltage drop = bad contacts).
Emergency operation
For manual actuation, the following solenoids must be actuated:
