Remedy
1.
No operating or control voltage
1.
Check fuses, main switch and supply line
Unit cannot be started
2.
Malfunction not acknowledged
2.
Acknowledge fault message
3.
Pressure reservoir not depressurized
3.
Wait until depressurized. Screw
compressor does not start up, when
reservoir pressure is > 0.8 bar/11.6 PSI
4.
Electric motor defective
4.
Check connections, winding, etc.
5.
Compressor defective
5.
Turn the compressor manually;
if required, replace
6.
Ambient temperature less than
+1 °C/ 33.8 °F
6.
Make sure that the ambient temperature
is not less than +1 °C/ 33.8 °F; install an
auxiliary heater, if required
7.
Remote control/timer has been
activated via terminal strip
7.
Deactivate remote control/timer
8.
Mains pressure is above the lower switch
set point
8.
Wait until the mains pressure has fallen
below the lower switch set poin
Unit stops during the
start-up phase
1.
Intake regulator only closes partly,
pressure builds up too quickly in the
pressure reservoir
1.
Fix intake regulator or, if required,
replace; check solenoid valves
2.
Short-circuit in the unit
2.
Determine and eliminate cause; replace
defective fuses
3.
Connecting terminals in the switch
cabinet are loose
3.
Check and re-tighten
4.
Oil too viscous
4.
Select the type of oil according to the
ambient conditions or install an auxiliary
heater
5.
Maximum motor switching cycles
exceeded due to too frequent manual
on and off-switching
5.
Avoid frequent manual on and off-
switching, let electric motor cool down
1.
Mains pressure sensor set too low
1.
Check, re-set
Unit does not reach the
set mains pressure
2.
Intake regulator opens only partly
2.
Fix intake regulator or, if required,
replace; check solenoid valves
3.
Excessive air consumption
3.
Reduce consumption or cut in a further
compressor
4.
Fine separator clogged
4.
Replace fine separator cartridge
5.
Air filter clogged
5.
Replace air filter cartridge
6.
Heavy leakage in the compressor
