Problem
Possible Cause
Corrective Action
2. Voids in powder
pattern
Worn nozzle or deflector
Remove the nozzle and deflector.
Inspect and replace them if
necessary.
Plugged powder path
Disassemble the powder path and
clean all parts.
3. Loss of wrap, poor
transfer efficiency
Electrostatic voltage insufficient
Increase the electrostatic voltage.
Dirty or broken electrode
Clean or replace the electrode
(contact tip).
Resistor, multiplier, or IPS control
unit failure
Check the multiplier/resistor probe
assembly with a megohmmeter for
208
−
312 megohms at 500 volts. If
the reading is out-of-range, check the
resistor probe separately.
Poorly grounded parts, hangers, or
conveyor
Check the conveyor chain, rollers
and part hangers for powder buildup.
Clean them and check for
one megohm or less resistance
between parts and ground. For best
results, resistance should be no more
than 500 ohms.
Failed resistor in optional nozzle
extension
Check resistor with a megohmmeter
for 18
−
22 megohms at 500 volts.
4. No kV output from
spray gun
Damaged gun cable
Check the continuity of the cable
wires, from pin to pin. Replace the
cable if any opens or shorts found.
Malfunctioning voltage multiplier
Use the optional shorting plug and a
megohmmeter to check the continuity
and resistance of the
multiplier/resistor assembly for
208
−
312 megohms at 500 volts. No
burn-throughs or arc tracks should be
visible on any gun parts.
Failed gun resistor
Check the resistor with a
megohmmeter for 153-187 megohms
at 500 volts. No burn-throughs or arc
tracks should be visible on any parts.
Malfunctioning IPS control unit
Repair or replace the control unit.
Failed resistor in optional nozzle
extension
Check resistor with a megohmmeter
for 18
−
22 megohms at 500 volts.
