“Engine running” conditions
- RPM > Engine params: Starting RPM or
- Analog input Oil pressure > Engine params: Starting POil or
- D+ terminal active and Engine params: D+ function = ENABLED or
- Active Binary input RunIndication1 or
- Active Binary input RunIndication2 or
- Active Binary input RunIndication3 or
- Vgen > 15 V (any phase).
“Still engine” conditions
- Engine speed (RPM) = 0 and
- AI: Oil press < Starting POil and
- D+ terminal not active and
- BI: RunIndication 1 and 2 and 3 = not active and
- Generator voltage < 15V (all phases) and
- Generator frequency = 0 Hz and
- if all above conditions are fulfilled, additional 2s delay is necessary to confirm “still engine”
NOTE:
If any of the functions not used (e.g. BI RunIndication3 not configured), it’s state is omitted in the evaluation.
This is not valid for RPM comparisons, this condition is always active.
