CodeDescriptionPossible cause / Hint or Solution

C52 Wrong trucktype Wrong trucktype selected / # 22 is probably entered incorrectly / Check # 22. If #24=1, then #22=1

C80 Steer servo - Home reference error

C81 Steer servo - Home reference error

Reference sensor receives incorrect signal. [S65] Faulty reference sensor [S65] / Inspect the sensor cabling.

Defective home reference sensor [S65] / Low voltage feed to reference sensor. 12 V between cables 95-97 / Inspect the cabling to the reference sensor [S65] Check condition of [F50]

C82 Steer servo- drive current warning

C90 Communication problem with the expansion unit (Expansion unit 1)

C91 Communication problem with the expansion unit (Expansion unit 2)

C92 Programming warning (Expansion unit 1)

Steer servo drive current is exceeding 80% of maximum. Steering activity may be too intensive See also code E132

Verify the voltage supplied to the unit (A36: POWER SUPPLY 24VDC) and check that the CAN cabling is OK

Verify the voltage supplied to the other expansion unit and check that the CAN cabling is OK.

Incorrect programming of expansion unit “SEU” 1 [A36]. The truck travels at creep speed. / May have been caused by incorrect allocation of an output during adjustment of the option parameters (16 to 19). Verify all settings of any option parameters...

C93 Programming warning (Expansion unit 2)

Incorrect programming of expansion unit “SEU” 2. The truck travels at creep speed. / May have been caused by incorrect allocation of an output during adjustment of the option parameters (16 to 19). Verify all settings of any option parameters.

E101 Transistor regulator [A1] incompatible with the type of truck

E104 Brake switch transistor output in transistor regulator [A1] shorted

E106 Digital output fault or field current limit

An incorrect transistor regulator type has been installed. / Verify that the correct transistor regulator type has been installed.

Defective transistor regulator [A1] / Check cables and magnetic coil to the brake [Y1]

Attempting to drive more current than specified from outputs.

OR problem regulating field current. Internal transistor regulator fault. [A1]
