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.

4.8.4 Running feedback
Different types of running feedback can be used to detect if the motor is running. Refer to menu 6170 for se-
lection of the running feedback type.
The running detection is made with a built-in safety routine. The running feedback selected is the primary
feedback. At all times, all the types of running feedback is used for running detection. If, for some reason, the
primary choice is not detecting any running feedback, the starter relay will stay activated for 1 additional sec-
ond. If a running feedback is detected based on one of the secondary choices, the genset will start. This way,
the genset will still be functional even though a tacho sensor is damaged or dirty.
As soon as the genset is running, no matter if the genset is started based on the primary or secondary feed-
back, the running detection will be made, based on all available types.
