POSSIBLE CAUSE
No voltage in pressure switch
Disconnected winding of motor, damaged
thermal protection
Faulty capacitor
Seizure of piston or another rotary part
Pressure switch does not switch on
Air leak in pneumatic distribution system
Leaking check valve
Greater volume of condensed liquid in
pressure vessel
Air leak in pneumatic distribution system
Worn piston ring
Contaminated input filter and prefilter
Dirty filter in the dryer
Defective solenoid valve
Damaged bearing of piston,
motor bearing
Loose or cracked spring
Devaluated or very polluted dessicant
low operating pressure
inoperative solenoid valve
clogged nozzle of the regenerating air
inoperative cooler ventilator
leak of white liquid through the solenoid
valve
defective solenoid valve
damaged damping substance in the
condensate vessel
damaged pressure hose
Check voltage in socket
Check fuse – replace faulty one
Loosen terminal – tighten it
Check power cord – replace faulty one
Replace motor or re-wind it
Replace capacitor
Replace damaged parts
Check the function of pressure switch
Check pneumatic distribution system – seal
loose joint
Clean valve, replace seals, replace valve
Drain condensed liquid
Check pneumatic distribution system – seal
loose joint
Replace worn piston ring
Replace contaminated filters with the new
ones
Change the outlet filter and inspect dessicant
Repair or change the valve
piston rod, Replace damaged bearing
Replace damaged spring
Change the dessicant and filters
reduce the air offtake, check the source
efficiency,
check possible leaks in the distribution
repair or change the valve
clean or replace the nozzle, use correct size
of the nozzle (see Product maintenance)
replace ventilator
energy
dismantle the chamber, replace drying
substance, bottom filter and sealing and
inspect tightness, apply soapy water onto O-
rings of the nuts
replace the valve
replace damping substance or the vessel
replace pressure hose
