TROUBLESHOOTING
TROUBLESHOOTING
Risk of electric shock.
Before any of the following operations on the device, disconnect the device from
the mains (pull out the mains plug).
Risk of injury during work with pneumatic components under pressure.
Before any of the following operations on the device, it is necessary to decrease
pressure in the air tank and in the pneumatic system to zero.
Any operations concerning the troubleshooting may be performed only by
a qualified technician.
Malfunction
Compressor does
not switch on
The cabinet switch
does not switch off
the compressor
Compressor often
switches on
Low pressure in
the air tank
(compressor
running constantly)
Prolonged
operation of the
compressor
12/2022
Possible cause
No voltage in the pressure switch
Motor winding failure, damaged
thermal protection
Capacitor failure
Seized piston or other rotating part
Pressure switch does not switch
There is a compressor in the cabinet
that previously worked separately
(there is a jumper in the compressor
terminal strip)
Air leakage in pneumatic system
Non-return valve (SV) leakage
Large volume of condensed liquid in
pressure tank
Low compressor capacity
High air consumption of supplied
equipment
Leakage in pneumatic system
Low capacity of the pump
Pump failure
Dryer failure
Air leakage in pneumatic system
Worn piston ring
Dirty inlet filter
Solution
Check voltage in socket
Check circuit breaker switch –
switch to position switched-on „I"
Loose conductor from terminal -
repair
Check electrical cord – replace
defective cord
Replace motor or windings
Replace capacitor
Replace damaged components
Check function of pressure switch
Remove the jumper from the
terminal strip, see chap. 23.11
Check pneumatic system – seal
loose connections
Clean non-return valve, replace
seals, replace non-return valve
Drain condensed liquid
Check time of filling the air tank
Decrease air consumption
Use compressor with higher
capacity
Check pneumatic system – seal
loose connections
Clean / replace the pump
Clean / replace the pump
Replace dryer
Check pneumatic system – seal
loose connection
Replace worn piston ring
Replace dirty filter with new filter
