POSSIBLE CAUSE
Tow Switch switched from "Tow" into
"Run" while vehicle is moving.
1. Stalled motor.
2. Motor encoder failure.
3. Bad crimps or faulty wiring.
4. Problems with power supply for the
motor encoder.
5. See Monitor menu » Motor: Motor RPM.
1. Dual Drive fault: see Dual Drive manual.
1. Dual Drive fault: see Dual Drive manual.
1. The Supervisor has detected a mismatch
in redundant readings.
2. Internal damage to Supervisor
microprocessor.
3. Switch inputs allowed to be within
upper and lower thresholds for over 100
milliseconds. (for recurring errors, check
the switches for moisture).
1. The main OS is not compatible with the
Supervisor OS.
1. Internal controller fault.
Appendix B
SET / CLEAR CONDITIONS
Set: Tow Switch (SW_4, Pin10) opens while the
vehicle speed is above the parameter Zero Speed
Threshold.
Clear: Cycle Keyswitch
Set: No motor encoder movement detected.
Clear: Either cycle KSI, or if parameter LOS Upon
Encoder Fault = On and Interlock has been cycled,
then the Stall Detected fault is cleared and Encoder
LOS fault (code 93) is set, allowing limited motor
control.
Set: Mismatched redundant readings; damaged
Supervisor; illegal switch inputs.
Clear: Check for noise or voltage drift in all switch
inputs; check connections; cycle KSI.
Set: Incompatible software.
Clear: Load properly matched OS code or update
the Supervisor code; cycle KSI.
Set: Internal controller fault detection.
Clear: Cycle KSI.
