Set-up
3) SAB 120→151, SAB 193→355, SAB 193 H→355 H, SAB 157 HR and SAB 273 S
4) SABflex and SABCube (same default value as for timer 31 Start unload)
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, SAB 193→355, SAB 193 H→355 H, SAB 157 HR and SAB
273 S
2) For SAB 120→151, SAB 193→355, SAB 193 H→355 H, SAB 157 HR and SAB 273 S
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.
1. SAB 120-151, SAB 193-355, SAB 193 H-355 H and SAB 273 S, timer is adjustable
2. Other screw types, fixed 300 sec.
17. Superheating low
During start the shutdown for low superheating is delayed for the stated time. No delay during normal
operation.
18. Superheating high
During start the shutdown for high superheating is delayed for the stated time. No delay during 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.
