Wiring Messages
The following are “wiring” HELP messages – problems have been detected which are likely due to
vehicle wiring issues:
FAULT: ENERGIZED VALVE - CHECK P5 WIRING! ____________ Flash Code: 3/2
FAULT: VALVE FEEDBACK HIGH - CHECK VALVE WIRING!_____ Flash Code: 3/2
There is a voltage on one or more valve outputs, when all outputs are off.
Check each valve output to trace where the invalid supply is coming from.
FAULT: CAPBANK VOLTAGE TOO HIGH - CHECK LINE CONT! __ Flash Code: 3/3
The voltage on the B+ stud of the controller (connected to an internal voltage stabilization
capacitor bank) is too high when the line contactor is off. B+ stud voltage should be
approximately 32 volts at idle.
Check the line contactor tips are not welded, and check the power wiring for errors.
FAULT: ENERGIZED LINE CONTACTOR - CHECK P5 WIRING! __ Flash Code: 3/4
There is a voltage on the line contactor coil output, when it is off.
Check wiring to the line contactor coil to trace where the invalid supply is coming from.
FAULT: MOTOR OVERLOAD! ______________________________ Flash Code: 3/5
The power protection circuits in the controller have activated to protect from extreme overload.
Check for short-circuit power wiring; check for a seized or shorted motor.
