8. Oil flow
When prelubrication is initiated, a signal must be issued from the float switch before the timer
expires; otherwise an error message appears.
1) For SAB 202, SAB Mk3 and VMY Mk3.
2) For SAB 163 Mk1.
3) For SV 10/20 and FV 10/20
4) For SAB 283, SAB 355, GSV, RWF and SAB 330 B. (B is short for Booster, which can be
selected in the Config. menu).
5) For SAB 330 HP. (HP means Booster = No).
6) For SAB 120→151, SAB 157HR, SABflex and SAB 193→355 prelubrication is not used.
9. Oil flow switch delay, start
When starting a compressor, a time delay ensures that the oil float has time to lift.
1) For SAB Mk2 110/128/163 and SAB 80.
2) For compressors with prelubrication delay = 0 sec.
3) For SV 10/20 and FV 10/20
4) SAB 120→151 and SAB 193→355 (Not used)
5) SABflex and SABCube
6) SAB 157HR (Not used)
10. No oil/flow
During operation the oil float is allowed to be disconnected only for the time period stated.
1) For SAB 110, 128, 163, 202 and VMY compressors
2) For SV 10/20 and FV 10/20
3) For GSV/RWF
4) For SAB 80
5) SAB 120→151, SAB 157HR and SAB 193→355
6) SABflex and SABCube
11. Lubrication time/flow
After start-up of compressors with prelubrication pump, the pump will run for the time stated
after compressor start.
1. For SAB 202, SAB Mk3 and VMY Mk3, SV 10/20 and FV 10/20
2. For SAB 163 Mk1
12. Diff. pressure OK
For VMY Mk3, SAB Mk3, SAB 202, SAB 283 Mk1, SAB 355 Mk1, SV 10/20 and FV 10/20 the oil
pump will run for the stated time after the desired differential pressure has been reached. The
timer is also used for SAB 120→151, SAB 157HR and SAB 193→355 compressors if fitted with
oil pump.
13. Oil pressure low
During start the shutdown for low oil pressure is delayed for the stated time. No delay during
normal operation.
1) For SAB 202, SAB Mk2, SAB Mk3, VMY, SAB 80, SAB 283 Mk1, SAB 355 Mk1, SV 10/20
and FV 10/20.
2) For SAB 163 Mk1
3) SAB 120→151, SAB 157HR and SAB 193→355
4) SABflex and SABCube (same default value as for timer 31 Start unload)
