“Engine started” conditions
-
Engine speed (RPM) >
Starting RPM
or
-
AI: Oil press >
Starting POil
or
-
D+ terminal active for minimum 1s or
-
BI: RunIndication 1 or 2 or 3 = active or
-
Generator voltage > 25% of
GenNomV
(any phase)
“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.
