ES On/Off switch is not turned
OFF (O).
Turn OFF (O).
Did not wait long enough for
voltage to discharge.
Wait longer before touching
electrode with grounding rod.
Check for bleed resistor failure.
Air pocket in fluid line leaves fluid
near gun isolated.
Determine cause and correct.
Purge air from fluid line.
Voltage isolation system failed.
Service voltage isolation system.
Voltage still present at
gun after following the
Fluid Voltage Discharge and
Grounding Procedure, page 39
.
Grounding cylinder not operating.
See
Test Cylinder Resistance, page 50
Replace if needed.
ES On/Off switch is OFF (O).
Turn ON (I).
Gun air pressure too low (ES
indicator is amber).
Check air pressure to gun;
minimum 45 psi (0.32 MPa, 3.2
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
.
Fluid leaks from the packing (2c)
and causes a short.
Clean the packing rod cavity, or
replace the packing rod. See
Faulty alternator.
See
ES HI/LO switch is on LO (Smart
guns only)
Check switch actuation; replace if
needed.
Poor wrap.
Spilled paint, dried paint, or other
contaminants inside the WB100
Enclosure, causing a short circuit.
Clean interior of enclosure.
ES On/Off switch is OFF (O).
Turn ON (I).
ES or Hz indicator is not lit.
No power.
Check power supply, alternator,
and alternator ribbon cable. See
Power Supply Removal and
Replacement, page 66
