Engine run time delay
Cool-down period
Inhibit run input applied
1 Battery voltage above
54VDC and finish charging cur-
rent below 30ADC
2 Engine temperature above
8°C
3 Start battery voltage above
12.9V and finish charging cur-
rent below 30ADC
This period ensures that no fur-
ther call to start conditions
occur prior to cool-down period.
Alternator output is reduced to a
minimal level to allow the engine
to cool down.
