Fault messages:
The following reactions can be witnessed on the truck when a fault occurs:
W Warning lamp flashing
K Truck drives at creep speed
B Truck brakes to a standstill or remains stationary if not yet moving
R Current only achieves start of pump control
E All power stages without power
L Engine goes to low idling speed
F Release magnet de-energised, truck braking with brake jets (restrictors)
S Safety relay in the controller de-energised, all power stages without power
19 No calibration
20 Invalid truck code
21 Invalid engine type code
22 Invalid series code
23 Invalid series/special truck code
31 Both pot signals do not match,
and neither is 0 V
32 UPot1 too low or too high
33 UPot2 too low or too high
34 Both pot signals at 0 V
35 Inadmissible pedal code and not all inputs are open
36 Inadmissible pedal code and all inputs are open
37 Both inputs of the brake microswitch
have the same status
38 Brake switch S14 switching before 1S5
39 Both inputs of the seat microswitch
have the same status
41 10 V power supply is too low (< 8 V) whereas
battery voltage is too high (> 11 V)
43 Power stage supply interrupted
(eg fuse blown, relay oxidized)
44 Power supply can not be cut out by relay
(relay sticking, final relay stage leaky)
45 Release power stage not conducting or
output shorted against (-)
46 Release power stage fused or
output shorted against (-)
47 Release magnet resistance too high
51 Engine control element resistance too low or
power stage leaky
52 Engine control element resistance too high or
power stage defective or magnet shorted against (-)
53 Pump control element V resistance too low or
power stage leaky
