TRACTION | DESCRIPTION OF | |
STATUS CODE | STATUS | |
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.

| DESCRIPTION OF | |
STATUS CODE |
| STATUS | |
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 | |
|
|
|
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.
