Trouble-s hooting
In the case of faults or warnings that are detected by the compressor control GD Pilot TS, please refer to the
chapter “Fault/warning table” in the operating instructions of the GD Pilot TS.
Malfunction
Possible cause
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
> 11.6 PSI (L30-L50) or
> 29.0 PSI (L30RS-L45RS)
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 33.8 °F
6.
Make sure that the ambient temperature
is not less than 33.8 °F; install an
auxiliary heater, if required
7.
Remote control/timer has been activated
7.
Deactivate remote control/timer
8.
Mains pressure exceeds the lower
switching point (L30-L50) or the
prescribed pressure (L30RS-L45RS)
8.
Wait until the mains pressure has fallen
below the lower switching point
Unit stops during the
start-up phase
1.
Suction regulator only closes part way,
pressure builds up too quickly in the
pressure reservoir
1.
Make the suction regulator viable,
replace if necessary, check the solenoid
valve
2.
System short
2.
Determine cause and remedy, replace
defective fuses
3.
Connection terminal in switch cabinet is
loose
3.
Check and tighten
4.
Oil is too viscous
4.
Choose type of oil which suits the
environmental conditions or install an
idle heater
5.
Maximum motor cycles exceeded due to
manually switching off and on too often
5.
Avoid frequent manual on and off
switching, let the electric motor cool
1.
System pressure sensor set too low
1.
Check, reset
Unit does not reach
the set mains
pressure
2.
Suction regulator only opens partially
2.
Make the suction regulator viable,
replace if necessary, check the solenoid
valve
3.
Air bleed too large
3.
Throttle the bleed or attach additional
compressors
4
Fine oil separator is dirty
5.
Replace the fine oil separator cartridge
5
Air filter is dirty
6.
Replace air filter cartridge
6
Large leaks in the compressor system
7.
Check the unit
