SECTION 6
Table 6-1: Troubleshooting Guide
SYMPTOM
Compressor Shuts Down With
Air Demand Present (continued)
Compressor will not build up full
discharge pressure
Line pressure rises above
unload P2 pressure setting on
Excessive Fluid Consumption
Pressure Relief Valve Opens
Repeatedly
Liquid Water in Compressed Air
Service Line
PROBABLE CAUSE
P1 is less than 10 psig (0.7 bar)
(P1 low display)
Air demand is too great
Dirty air filter
Pressure Regulator Out of
Adjustment
Defective Pressure Regulator
Broken Sullicon Spring
Leak in control system causing
loss of pressure signals
Defective solenoid valve
Defective blowdown valve
Ruptured Sullicon control
diaphragm
Plugged control line filter.
Clogged return line strainer or
orifice
Separator element damaged or not
functioning properly
Leak in the lubrication system
Excess fluid foaming
Fluid level too high
Defective pressure relief valve
Water Vapor Condensation From
Cooling and Compression Occurs
Naturally

REMEDY
First, check starter wiring. If discharge
pressure is above 10 psig (0.7 bar) was
connections from transducer. If adequate,
replace transducer.
Check service lines for leaks or open valves.
Check for filter maintenance message on
clean element if required.
Adjust regulator according to control
adjustment instructions in the Maintenance
Section.
Check diaphragm and replace if necessary (kit
available).
Replace.
Check for leaks.
Check that Sullicon control lever is moved to
NO LOAD mode. Repair or replace if
necessary (kit available).
Check that sump pressure is exhausted to the
atmosphere when in the OFF LOAD mode.
Repair or replace if necessary (kit available).
Replace.
Clean or repair if necessary.
Clean strainer (screen with o-ring replacement
kit available).
Clean orifice.
Check separator differential (plugged) dP1.
Change separator elements.
Check all pipes, connections and components
Drain and change.
Drain excess fluid.
Replace pressure relief valve.
Remove the water vapor from compressed air
prior to distribution through the air system.
Check operation of aftercooler and moisture
separator. Install a compressed air dryer sized
for the flow and dryness level required. (Note:
Filters may also be required to remove
particulates, liquid oil aerosols or for oil vapor
removal. Change cartridges as recommended
by the filter manufacturer.) Check all drain
traps routinely to insure their proper operation.
Maintain them regularly.
