FAULT TROUBLESHOOTING GUIDE
Before troubleshooting gun and control unit problems, flush the gun with solvent and purge
with air. Some of the tests will require high voltage to be applied to the gun, so the gun must
be empty of paint and solvent.

Fault Description Solution
Cable Fault (CF) The Cable Fault indicates the con-
trol unit does not detect a high
voltage section on the end of the
cable. The fault typically occurs at
a high voltage trigger. 1. Check for loose wiring between the pc
board connector and the high voltage sec-
tion by pulling on each wire. Repair if nec-
essary. Insure both connectors are secure
and re-test for CF fault.
2. Replace high voltage section or send unit
in for repair.
3. Send unit in for repair.
Ground Fault (GF) The Ground Fault is typically
caused by a ground connection
problem, and can create a safety
hazard. It can occur without high
voltage and will not reset. 1. Check for loose wiring between the pc
board connector and the high voltage sec-
tion by pulling on each wire. Repair if nec-
essary. Insure both connectors are secure
and re-test for GF fault.
2. Adjust the setpoint to 20kV and turn on the
high voltage. A GF fault indicates a faulty
pc board - replace.
3. Replace high voltage section or send unit
in for repair.
4. Send unit in for repair.
Over-Voltage Fault
(OU) The Over Voltage Fault indicates
the output voltage exceeds the
design specifications. It typically
occurs during a high voltage trig-
ger. 1. Check connections using two finger pull
test to ensure they are connected.
2. Replace the pc board.
Boot Fault (bF) The Boot Fault indicates that the
microprocessor has detected the
gun on-off switch in the on posi-
tion during the start-up sequence. 1. Turn off the voltage controller, turn the gun
on-off switch to the “off” position, turn on
the voltage controller.
2. Send system in for repair.
