In order to insure fast and reliable crank cutting, the unit uses various resources for engine running
condition detection.
Cranking is stopped when
at least one
of below conditions is met:
- Crank timer expired:
The crank timer is adjusted through programming menu. The maximum allowed timer is 15
seconds.
- Genset AC voltage over threshold:
If the genset phase L1 AC voltage reaches
Crank Cut Voltage
, then cranking is immediately
stopped.
- Genset frequency over threshold:
If the genset phase L1 frequency reaches
Crank Cut Frequency
, then cranking is
immediately stopped.
- Charge alternator voltage over threshold
Following setting is necessary:
Crank Stop with Charge = 1
If the charge alternator voltage reaches 6 volts, then cranking is immediately stopped.
- Oil pressure above threshold
Following setting is necessary:
Crank Cut with Oil Pressure = 1
The crank cutting with oil pressure offers a fixed delay of 2 seconds.
Both low oil pressure switch and oil pressure sender readings may be used for crank cutting.
The oil pressure switch is always used.
When oil pressure is above the Low Oil Presure Shutdown Limit, cranking is stopped after
adjustable timer delay.
