9.9.1 Error codes and troubleshooting
The table below describes the error codes that can be displayed with
the status light or read on the hand unit.
STATUS LED Text on hand
unit
Explanation Possible cause
LED off - No voltage or error in
the regulator.
Defective fuse, poor contact, not con-
nected, error in the regulator.
LED on - Error in the regulator. Error in the regulator.
1,1 ¤ ¤ CURRENT
SHUNT FAULT
Error in the built-in
current shunt.
Error in the rotor current sensor in the
motor monitor.
1,2 ¤ ¤¤ HW FAILSAFE CAN timeout in
power amplifier.
The motor monitor is reporting an
unexpected data loss from the tiller
arm head.
1,3 ¤ ¤¤¤ M- SHORTED Internal M- short
circuited to B-.
Problem with switch transistor in the
rotor circuit inside the motor monitor.
3,1 ¤¤¤ ¤ CONT COIL/FLD
SHORT
Voltage too high for
contactor feed or
short-circuited field
winding.
Attempt to extract more current than
the output device can manage.
Problem regulating the field current.
Internal monitoring error.
3,3 ¤¤¤ ¤¤¤ FIELD OPEN Open field winding. Shunt field open, defective cable,
defective motor monitor.
4,1 ¤¤¤¤ ¤ LOW BATTERY
VOLTAGE
Low battery voltage. 1. Battery voltage < 17 volt.
2. Battery poles affected by corrosion.
3. Loose battery or regulator connec-
tions.
4,2 ¤¤¤¤ ¤¤ OVERVOLTAGE Voltage too high. 1. Battery voltage > 33 volt.
4,3 ¤¤¤¤ ¤¤¤ THERMAL CUT-
BACK
