1) May occur as alarm in MAN and AUTO.
2) Shutdown at prelubrication. Alarm during operation.
3) HPO/HPC only.
4) The shutdown Low oil pump pressure during operation applies to SAB 80. The shutdown is only activated at a discharge pres-
sure level below 16 bar.
5) Shutdown relay can be deactivated.
NA = Not available
