Digital Feedbacks
If an external running relay is installed, the digital control inputs for running detection or
remove starter can be used.
Running Feedback
When the digital running feedback is active, the start relay is deactivated, and the
starter motor will be disengaged.
The diagram illustrates how the digital running feedback is activated when the engine
has reached its firing speed.
Remove Starter
When the digital remove starter input is present, the start relay is deactivated, and the
starter motor will be disengaged.
The diagram illustrates how the remove starter input is activated when the engine has
reached its firing speed. At the running speed, the digital running feedback is activated.
NOTE: The remove starter input must be configured from a
number of available digital inputs.
NOTE: The running feedback is detected by either the digital input
(see diagram above), frequency measurement above 32 Hz, RPM
measured by magnetic pick-up or Engine Interface communication.
