TROUBLESHOOTING
Risk of electric shock.
Before interfering with the
equipment, first disconnect it
from the mains (remove the
power socket).
Working with pressurised
pneumatic components poses a
risk of injury.
Before interfering with the
equipment, vent the air tank and
the compressed air system to
zero pressure.
Troubleshooting may only be
performed
by a qualified
service technician.
Damage to the safety valve
could cause pressure to rise to
hazardous levels.
Never adjust a safety valve.
Malfunction Possible cause Solution
Compressor does
not switch on
No voltage in the pressure switch
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
Motor winding failure, damaged
thermal protection
Replace motor or windings
Capacitor failure Replace capacitor
Seized piston or other rotating part Replace damaged components
Pressure switch does not switch Check function of pressure switch
Controller malfunction
Check controller operation, check to
ensure software is present - replace
if damaged or upload the correct
program
RUN/STOP
indicator is not
green
Loss of connection between
controller and expansion module Check connection
– replace if
damaged
Power loss
Check mains voltage
Loose terminal in switchboard -
tighten
Check the primary power
connection - replace if damaged
Problem with electrical power
source
Main breaker is off
Controller or expansion module
malfunction Replace failed controller or
expansion module
Compressor often
switches on
Air leakage in pneumatic system
Check pneumatic system
– seal
loose connections
Non-return valve (SV) leakage
Clean non-return valve, replace
seals, replace non-return valve
Leak through solenoid valves once Clean the check valve - replace if
