Operational Analysis
ENGINE SHUTDOWN
Following re-transfer back to the Utility source an “engine cool-down timer” on the controller starts timing. When the timer has
expired (approximately one minute), the controller will de-energize the internal run relay removing fuel from the engine. The following
events will occur:
•The DC circuit to Wire 14 and the fuel solenoid will open. The fuel solenoid will de-energize and close to terminate the fuel supply
to the engine.
•The controller’s logic will connect the engine’s ignition magnetos to ground via Wire 18. Ignition will terminate.
•Without fuel flow and without ignition the engine will shut down.
