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 Engine Parameters > Crank Timer . The maximum allowed
timer is 15 seconds.
- Genset AC voltage over threshold:
If the genset phase L1 AC voltage reaches Engine Parameters > Crank Cut Voltage , then
cranking is immediately stopped.
- Genset frequency over threshold:
If the genset phase L1 frequency reaches Engine Parameters > Crank Cut Frequency , then
cranking is immediately stopped.
- Genset rpm over threshold:
If the genset rpm reaches Engine Parameters > Crank Cut RPM , then cranking is immediately
stopped.
- Charge alternator voltage over threshold
Following setting is necessary: Engine Parameters > Charge Input Connected = 1
If the charge alternator voltage reaches Engine Parameters > Crank Cut Charge Voltage , then
cranking is immediately stopped.
- Oil pressure above threshold
Following setting is necessary: Engine Parameters > Crank Cut with Oil Pressure = 1
The crank cutting with oil pressure offers a programmable delay through Engine Parameters >
Crank Cut with Oil Pressure Delay . The parameter is factory set to 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. The sender may be disabled through
Controller
Configuration > Oil Pressure Switch Priority parameter.
If enabled, when oil pressure is detected, cranking is stopped after adjustable timer delay.
