Electrical Troubleshooting
Problem Cause Solution
Poor wrap. Turbine air is not turned on. Turn on.
Booth exhaust velocity is too high. Reduce velocity to within code limits.
Atomization 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
29.
Low fluid resistivity. Check fluid resistivity, page 17.
Fluid leaks from the packing (8d) and
causes a short.
Clean the packing rod cavity.
Replace the packing rod. See page
41.
Faulty turbine alternator. Be sure the plug is in place on the
back of the turbine alternator hous-
ing. Remove and test the turbine
alternator. See page 47.
The KV switch is stuck on low. Check the switch actuation; replace if
needed.
No power. Replace power supply. See page 46.
No voltage or low voltage reading on
the gun ES display module
Damaged fiber optic cable or connec-
tion.
Check; replace damaged parts.
Turbine air is not turned on. Turn on.
Poor wrap. See causes and solutions under Poor
Wrap, above.
Operator gets mild shock. Operator not grounded or is near
ungrounded object.
See Grounding on page 15.
Gun not grounded. See Check Electrical Grounding on
page 16 and Test Gun Resistance
on page 29.
Operator gets shock from workpiece. Workpiece not grounded. Resistance must be 1 megohm or
less. Clean workpiece hangers.
