DIAGNOSTIC STATUS CODES

SX TRANSISTOR CONTROL Page 36

TRACTION	DESCRIPTION OF
STATUS CODE	STATUS
-65	The line coil current is too high
	during the run mode
MEMORY RECALL	CORRECTIVE ACTIONS
YES
	SYMPTOM
Circuits valid	Control will not operate.
for	POSSIBLE CAUSE
Traction	- Shorted line contactor coil
Controller	- Short between wires connected to
	line coil (wires #10 and 24)
	If line coil resistance is correct:
	Defective control.
	• Replace controller unit.

CAUSE OF STATUS INDICATION

This status code will be displayed when the current limit in the line coil is exceeded during the run mode. The line contactor will drop out and the key switch will have to be recycled to reset the control.

TRACTION		DESCRIPTION OF
STATUS CODE		STATUS
-66	The field current exceeds the
	current limit of the field transistor.
MEMORY RECALL	CORRECTIVE ACTIONS
YES
	SYMPTOM
Circuits valid	Control will not operate
	•	Line contactor opens
for	POSSIBLE CAUSE
Traction	•	Shorted field F1 to F2
	• F1 or F2 terminals shorted to battery
Controller		positive (B+)
	•	F1 or F2 terminals shorted to battery
		negative (B-)

CAUSE OF STATUS INDICATION

This status code will be displayed when the field transistor exceeds its specific current limit. The line contactor will drop out and the key switch will have to be recycled to restart the control.
