INFO
Run coil can be activated from 1 to 600 sec. before crank (starter) will be executed. In the above example, the timer is set
to 1 sec. (menu 6150).
2.9.2 Start sequence conditions
The start sequence initiation can be controlled by the following conditions:
• Multi-input 102
• Multi-input 105
• Multi-input 108
This means that if, for example, the oil pressure is not primed to the sufficient value, the crank relay will not engage 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 set point 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.
The diagram below shows an example where the RMI signal builds up slowly and starting is initiated at the end of the third start
attempt.
