Automatic Shut-down System

This unit is equipped with safety devices to automatically stop the engine in the event of low oil pressure, approximately 14 psi (97 kPa), or high water temperature, approximately 230° F (110° C), overspeed approximately +15%.The alarm lamps on the ECU illuminate to signify the reason for the shutdown.

NOTICE

Before inspecting generator, check that the Auto/ Manual switch is in the OFF/RESET position, and place all circuit breakers in the OFF position. Allow sufficient time for adequate cooling. When ready to restart, complete all steps in the Generator Startup Procedure section of this manual.
