POSSIBLE CAUSES
Controller
 Shorted field F1 to F2
 F1 or F2 terminals shorted to battery
positive (B+)

Confirm that all inductive
loads/accessories are suppressed.

Motor armature or field shorted to
frame.
Defective control.

Replace controller unit.
DESCRIPTION OF
STATUS
Replace controller unit.
CORRECTIVE ACTIONS
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.
