Description
Possible cause / Hint or Solution
E107
Main contactor not activated [K10]
Problem with main contactor tips or cabling (open circuit). Contactor control wire not connected. Incorrect contactor output from the transistor regulator (switched off). / Inspect the main contactor tips. Check control wires to main contactor. Check contactor drive output goes {low}. [A1]
E108
Main contactor tips welded or open circuit in coil.[K10]
Main contactor tips welded. Contactor drive output in controller faulty (on) / Check main contactor tips Check contactor drive output goes {high}. [A1]
E110
Incorrect rotor current value. [M1, A1]
Defective transistor regulator [A1]. Can be caused by excessive moisture inside regulator. / Restart the truck.
E113
Unspecified steer servo fault
Control system has detected a fault condition but is unable to ascertain the exact cause. / Restart the truck.
E114
Steer servo phase error [A5, M6]
Loss of motor phase to steer servo motor. / Check internal motor cable connections in steer servo
E115
Steer servo start up error [A5]
Faulty Servo Internal logical fault Incorrect parameter settings. / Restart the truck.
E116
Steer servo checksum error [A5]
Can occur after new software has been loaded into truck. / Restart the truck.
E117
Steer servo communication error
Not used
E118
Command mode error
Not used
E119
Steer servo error during homing operation (Time out)
Home position (steering straight) not achieved within preset time. Home reference sensor [S65] not adjusted correctly Faulty reference sensor / Check reference sensor gap is adjusted correctly, check wiring to sensor.
E120
Error in steer servo potentiometer
Not used
E121
Steer servo error -steering angle value check
Defective steering signal potentiometer [R2] or cabling / Restart the truck. The sum of the voltages between cables 92-94 and 93-94 =5 V Recalibrate steering. See# 36 - Steer servo calibration on page 46
E122
Steer servo -reference supply out of range
Defective steer servo [A5] / Check voltage between wire nos. 91-94 = 4,5 to 5,5 V.
E123
Steer servo - Hall sensor fault
Intermittent contacts inside steer servo Defective steer servo [A5] / Check internal contacts in steer servo [A5].
E124
Steer servo - overvoltage [A5]
Fully charged battery and energy regeneration during hard reversing braking. / Restart the truck.
