Traction
POSSIBLE CAUSES
• Shorted field F1 to F2
Controller
• F1 or F2 terminals shorted to battery
• Binding line contactor
• Visually inspect tips, clean them with a
• Blown FU1 fuse.
• Noise
• Confirm that all inductive

TRACTION
STATUS CODE
The armature current exceeds the
-67
armature transistor limit.
MEMORY RECALL
YES
SYMPTOM
Control will not operate.

POSSIBLE CAUSE
Traction
• Shorted motor armature A1 to A2
Controller
• Power cables may be shorted to
each other (Measure at control
terminals)
• A1 to A2 terminals may be shorted
to battery positive or negative
DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
positive (B+) or to battery negative (B-)
solvent.
loads/accessories are suppressed.
DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
CAUSE OF STATUS INDICATION
This status code will be displayed when the field
transistor exceeds its current limit. The line contactor
will drop out and the key switch will have to be
recycled to restart the control.

CAUSE OF STATUS INDICATION
This status code will be displayed when the armature
transistor exceeds its specific current limit. The
control is reset by recycling the key switch.
