14. Filter diff. high
During start and operation the shutdown for high filter differential pressure is delayed for the
stated time.
1) For all compressors except SAB 120→151 and SAB 193→355
2) For SAB 120→151, SAB 157HR and SAB 193→355
15. Oil temp. low
During start the shutdown for low oil temperature is delayed for the stated time. No delay
during normal operation.
16. Oil temp. high
During start the shutdown for high oil temperature is delayed for the stated time. No delay
during normal operation.
17. Superheating low
During start the shutdown for low superheating is delayed for the stated time. No delay dur-
ing normal operation.
18. Superheating high
During start the shutdown for high superheating is delayed for the stated time. No delay dur-
ing normal operation.
19. Disch. pressure, overload
If the discharge pressure is higher than the alarm limit in the time stated, the compressor will
stop and an error message will appear. See also 3.2. Limiting functions.
20. Current overload
If the motor current or power is higher than the set point in the time stated, the compressor
will stop and an error message will appear. See also section 3.2. Limiting functions.
21. Motor start
When the compressor starts, the motor guard must issue a feedback before the timer expires.
If not, an error message will appear.
The green light diode above the start key
will flash until feedback has been received.
Then the light will be steady.
22. PMS (Starting request) feedback
After the control has issued a starting request, it must receive a feedback within the stated
time. If not, an error message will appear.
23. F. F. Pump start
In case the motor guard of the full flow pump/Cooling FAN has failed to issue a feedback with-
in the stated time after the starting signal, an error message will appear.
24. Oil pump start
In case the motor guard of the oil pump has failed to issue a feedback within the stated time
after the starting signal, an error message will appear.
