•
GE Sentry for Windows software can
be used to monitor control operation,
and it will display a value for the motor
amps that is less than 117
(corresponding to 2.3V), triggering this
status code.
TRACTION DESCRIPTION OF STATUS
STATUS CODE
Armature transistor did not turn off
-44
properly.
MEMORY RECALL
YES
SYMPTOM

CORRECTIVE ACTIONS
Replace controller unit.
CORRECTIVE ACTIONS
Turn tow switch off for 20 seconds
and then turn tow switch back on.
Replace controller unit.
CAUSE OF STATUS INDICATION
This status code will be displayed when the value of
motor amps is less than 117 (corresponding to 2.3
volts) with no current flowing in the motor circuit.
TROUBLE-SHOOTING DIAGRAM
CAUSE OF STATUS INDICATION
This status code will be displayed when, during
control operation, the armature transistor fails to turn
off. This will result in a PMT condition
