Troubleshooting
Low or Fluctuating Output
PROBLEM
Low Output
32
CAUSE
1.
Worn spray tip.
2.
Verify pump does not continue to stroke when
applicator is turned off.
3.
Filter clogged (If optional filter is installed).
4.
Material hose length. Longer hose length
reduces sprayer performance.
5.
Pump hopper adapter connections.
6.
Electrical supply with volt meter. Meter must
read:
210-255 Vac for 220-240 Vac models;
85-130 Vac for 100-120 Vac models. Low
voltages reduce sprayer performance.
7.
Extension cord size and length; must be at least
1.0 mm2 (12 awg) wire and no longer than 90 m
(295 ft). Longer cord lengths reduce sprayer
performance.
8.
Leads from motor to pressure control circuit
board for damaged or loose wires or connectors.
Inspect wiring insulation and terminals for signs
of overheating.
9.
Low stall pressure.
SOLUTION
1.
Follow Pressure Relief Procedure
Warning, then replace tip. See your
separate gun or tip manual.
2.
Service pump. Check piston and intake
valves for wear or obstructions.
3.
Relieve pressure. Check and clean filter.
4.
Replace with hose length less than
specified maximum.
5.
Tighten any loose connections. Replace
pump hopper adapter if cracked or
punctured.
6.
Reset building circuit breaker; replace
building fuse. Repair electrical outlet or
try another outlet.
7.
Replace with a correct, grounded
extension cord.
8.
Be sure male terminal blades are
centered and firmly connected to female
terminals. Replace any loose terminal or
damaged wiring. Securely reconnect
terminals.
9.
Turn pressure control knob fully
clockwise. Make sure pressure control
knob is properly installed to allow full
clockwise position. Try a new transducer.
