Shutdowns
A shutdown secures the fuel and a shutdown secures the air to the engine. A fuel shutoff solenoid may be located in the fuel actuator. The fuel shutoff solenoid is energized. The injector is driven to the off position. This secures the fuel.The air shutoff solenoid secures the air. When this solenoid is activated compressed air flows to the air damper. The air releases a pin. When the pin is released, a spring closes the air damper. This secures the combustion air supply from the turbochargers to the aftercooler.Note: The air damper must be MANUALLY reset before the engine can be restarted. The Marine Engine Control Panel must also be reset with the "RESET" switch before the MMS will allow starting. The panel may not be reset until the engine has stopped rotating. Determine the cause of the shutdown and correct the problem prior to engine operation.
