 (Detailed  procedures  on  troubleshooting  of  the  compressor  system  can  be  found  in 

“Compressor 

Information (APPENDIX-A)”. 

 

Fault 

Possible cause 

Remedy 

Not functioning 

Control box or electrical 

connection faulty 

Have control box or electrical 

connection repaired. Incorrect 

rotation direction Phases reversed 

Reconnect 

Incorrect rotation direction 

 

Hoses are connected wrongly 

 

Reconnect supply and return hoses 

Screw compressor system 

has difficulty starting 

 

Flow and pressure not 

insufficient 

 

Inspect 

Drive transmission ratio too fast 

Check flow and pressure 

Star-delta switchover incorrect 

Set 

Compressor is flooded with oil 

Check 

System has not been 

depressurized yet 

Check, depressurize if necessary 

Ambient temperature too low 

Check viscosity of the oil 

Oil filling too viscous 

Check viscosity of the oil 

Pressure losses at 

filter cartridges 

Excessive pressure loss at 

air-oil separating element 

Replace air-oil separating element 

Combistat switches off 

due to excessively high 

temperature 

  

  

  

  

  

Oil shortage 

Check the oil level in the oil 

reservoir, fill if necessary 

Oil filter soiled 

Replace oil filter cartridge 

Oil thermostat faulty 

Replace oil thermostat 

Oil cooler soiled 

Clean oil cooler on air side, clean 

on oil side if necessary 

Incorrect setup 

a) Room ventilation 

b) Exhaust air obstructed 

c) Thermal short-circuit 

Follow recommendations for 

installation of the compressor 

system 

Combistat defective 

Replace combistat 

Safety valve blows off 

(at a permissible operating 

pressure) 

Safety valve defective 

Replace safety valve 

Air-oil separating element dirty 

Replace air-oil separating element 

Compressor system does not 

switch off automatically, control 

valve operates intermittently 

Check the solenoid valve, replace 

if necessary 

 

 

Oil in compressed air 

 

 

 

Operating pressure and 

delivery quantity is not in the 

permissible range 

Check pressures 

Oil exhaust system 

contaminated 

Clean oil extraction system 

 

Air-oil separating element faulty 

Check air-oil separating element 

and replace if necessary 

Oil level in oil reservoir 

too high; possibly 

excessive condensate 

Observe oil level marking; drain 

and replace if necessary
