Traction
POSSIBLE CAUSES
Controller
•=Shorted field F1 to F2
•=F1 or F2 terminals shorted to battery
positive (B+) or to battery negative (B-)
•=Binding line contactor
•=Visually inspect tips, clean them with a
solvent.
•=Noise
•=Confirm that all inductive
loads/accessories are suppressed.
•=Excessive motor and control heating
(control is in thermal cutback)
CORRECTIVE ACTIONS
Replace controller unit.
CORRECTIVE ACTIONS
CAUSE OF STATUS INDICATION
This status code will be displayed when the voltage
input from the current sensor is too low (less than
1.43V, -350 amps) during running.

NO GRAPHIC FOR THIS
STATUS CODE
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.
