Electrical Troubleshooting
* ES indicator light is off when the gun is triggered.
Problem Cause Solution
Poor wrap. ES ON/OFF valve OFF (0).* Turn ON (I).
Gun air pressure too low. Check air pressure to gun; minimum
40 psi (0.28 MPa, 2.8 bar) needed at
gun for full voltage.
Atomizing air pressure too high. Decrease.
Fluid pressure too high. Decrease.
Incorrect distance from gun to part. Should be 8-12 in. (200-300 mm).
Poorly grounded parts. Resistance must be 1 megohm or
less. Clean workpiece hangers.
Faulty gun resistance. See Test Gun Resistance on page
18.
Low fluid resistivity. Check fluid resistivity, page 14.
Fluid leaks from the packing (26d)
and causes a short. Clean the packing rod cavity.
Replace the packing rod. See page
29.
Faulty turbine alternator. Be sure the plug is in place on the
back of the power supply housing.
Remove and test the turbine alterna-
tor. See page 32.
The KV HI-LO lever is on LO. Check the lever actuation; replace if
needed.
ES indicator or voltage/current dis-
play is not lit. ES ON/OFF valve OFF (0).* Turn ON (I).
No power. Replace power supply. See page 31.
Voltage/current display stays red
(smart guns only). Gun too close to part. Should be 8-12 in. (200-300 mm).
Check fluid resistivity. See Check Fluid Resistivity on
page 14.
Dirty gun. Clean. See Operation Manual.
Operator gets mild shock. Operator not grounded or is near
ungrounded object. See Grounding on page 12.
Gun not grounded. See Check Electrical Grounding on
page 13 and Test Gun Resistance
on page 18.
Operator gets shock from workpiece. Workpiece not grounded. Resistance must be 1 megohm or
less. Clean workpiece hangers.
