†
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.
Cable Fault (CF)
Ground Fault (GF)
Over-Voltage Fault
(OU)
Boot Fault (bF)
Over-Load Fault (OL)
The Cable Fault indicates the control unit
does not detect a high voltage section on
the end of the cable. The fault typically
occurs at a high voltage trigger.
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.
The Over Voltage Fault indicates the
output voltage exceeds the design
specifications. It typically occurs during a
high voltage trigger.
The Boot Fault indicates that the
microprocessor has detected the gun on-
off switch in the on position during the
start-up sequence.
The Over Load Fault indicates the current
output has exceeded the overload
threshold. This fault is only active if jumper
17 is shorted. The overload threshold for
the 80102-21X units is set to 140 µA.
Check for loose wiring between the pc board connector
and the high voltage section by pulling on each wire.
Repair if necessary. Insure both connectors are
secure and re-test for CF fault.
Replace high voltage section.
Send entire unit in for repair.
Check for loose wiring between the pc board connector
and the high voltage section by pulling on each wire.
Repair if necessary. Insure both connectors are
secure and re-test for GF fault.
Replace high voltage section.
Send entire unit in for repair.
Check connections using two finger pull test to ensure
they are connected.
Replace the pc board.
Turn off the voltage controller, turn the gun on-off
switch to the “off” position, turn on the voltage
controller.
Send entire system in for repair.
This may indicate the paint conductivity is too high
(resistance too low) or the outside of the applicator
is contaminated with paint.
Current Limit
Fault (CL)
The Current Limit Fault indicates the
current output of the gun has exceeded
the maximum allowable output current. It
typically occurs with the high voltage on.
Clean outside of the applicator.
Replace barrel or applicator.
Send applicator in for repair.
