CAUSE OF STATUS INDICATION
-65
The line coil current is too high
during the run mode
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.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Shorted line contactor coil
Short between wires connected
to line coil (wires #10 and 24)
Insure that all inductive loads
are suppressed.
Incorrect line contactor coil.
Defective control.
Replace controller unit.

STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-66
The field current exceeds the current limit
of the field transistor.
This status code will be displayed when the field
transistor exceeds its current limit. The line

SYMPTOM
Control will not operate or is sluggish on
start up. Line contactor opens.
POSSIBLE CAUSES
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.
