DIAGNOSTIC STATUS CODES
SX TRANSISTOR CONTROL
TRACTION
DESCRIPTION OF STATUS
STATUS CODE
The field current exceeds the current limit
-66
of the field transistor.
MEMORY RECALL
YES
SYMPTOM
Control will not operate or is sluggish on
Circuits valid
start up. Line contactor opens.
for
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)
TRACTION
DESCRIPTION OF STATUS
STATUS CODE
Capacitor (1C) voltage too high during
-76
pedal up regen braking.
MEMORY RECALL
YES
SYMPTOM
Line contactor opens and closes, then
Circuits valid
opens and can only close by opening
for
and closing the key switch.
Traction
Controller
POSSIBLE CAUSE
Defective control.
•=
Batteries are overcharged.
CORRECTIVE ACTIONS
CORRECTIVE ACTIONS
Replace controller unit.
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.
