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
contactor will drop out and the key switch will have
to be recycled to restart the control.

MEMORY RECALL

YES

Controller

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.
