2.9.3 Running feedback
Different types of running feedback can be used to detect if the motor is running. Refer to menu 6170 for selection of the running
feedback type.
The running detection is made with a built-in safety routine. The running feedback selected is the primary feedback. All configured
running feedbacks are used at all times. If, for some reason, the primary choice is not detecting any running feedback, the starter
relay will stay activated for one additional second. 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 feedback, the running
detection will be made based on all available types.
The sequence is shown in the diagram below.
