3.3 Trouble and remedy
For power supply, the set of cables with 16 A fuse and 2-pin socket outlet
included in the shipping package must be installed on the tractor.
Power supply should be by means of the original set of cables since a
corresponding cable cross-section is required.
A voltage converter is required for tractors with a 24 V system.
The forage wagon control
unit is without any function,
indicator light (P) does not
light up (3 seconds).
• Check fuse (8 = 16 A) in power supply cable on tractor.
• Check power supply cable for correct polarity.
• Check plug connections on key button housing and distributor box for
a tight fit.
• Check 2 bar switch (26 - NO contact, E).
The floor conveyor cannot
be switched on when
loading
• Check the oil supply from the tractor (has the directional control valve
been switched on, have the couplers been properly connected?)
• Check if the tailgate is fully closed (must be closed by pressure,
100% of light field must be Off).
• Check if a fault has been produced by manual switching of solenoid
(27), if a hydraulic or electric fault has occurred.
• Check the coil and the iron core of the solenoid (27).
• Coil resistance = 6.4 Ω.
• Check the voltage on solenoid without and then with a consumer
connected (voltage drop = bad contacts)
The floor conveyor cannot
be switched on when
unloading
• Check the oil supply from the tractor (has the directional control valve
been switched on, have the couplers been properly connected?)
• Check if the tailgate is fully open.
• The green indicator light (O) must flash.
• Check 150 bar switch (18 - NO contact, E).
• Check if a fault has been produced by manual switching of solenoid
(27), if a hydraulic or electric fault has occurred.
• Check the coil and the iron core of the solenoid (27).
• Coil resistance = 6.4 Ω.
• Check the voltage on solenoid without and then with a consumer
connected (voltage drop = bad contacts)
The tailgate will not close.
The indicator light (N) will
not flash.
The tailgate close pushbutton (F) must be pressed until the red indicator
light flashes in the key button housing.
• Check the bottom reed switch (15) on the tailgate, short-circuit cable.
• Check the plug connections according to the circuit diagram.
