4.8.3 Start sequence conditions

The start sequence initiation can be controlled by the following conditions:
●

RMI 6 (oil pressure)

●

RMI 7 (water temperature)

●

RMI 8 (fuel level)

This means that if e.g. the oil pressure is not primed to the sufficient value, then the crank relay will not en-
gage the starter motor.

The selection is made in setting 6185. For each of the RMI settings, the rule is that the value (oil pressure,
fuel level or water temperature) must exceed the setpoint of setting 6186 before starting is initiated.

If the value in 6186 is set to 0.0, the start sequence is initiated as soon as it is requested.
