Fault Description Solution
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.
3. Send unit in form repair.
Over-Load Fault
(OL) 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 is normally
set at 10 µA below the maximum
output of the applicator. 1. 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. 1. Clean outside of the applicator.
2. Replace barrel or applicator.
3. Send applicator in for repair.
Feedback Fault
(FF) The Feedback Fault indicates
there is no current feedback or it
is incorrect. It typically occurs
with the high voltage on. 1. Securely attach a ground wire to the appli-
cator electrode.
2. Set the high voltage to maximum and place
a jumper across the flow switch.
3. The current reading on the control unit
should rise up to the maximum current out-
put. If it does not, send the applicator in for
repair.
