The warnings and the overspeed shutdown will continue to function normally. When the Engine Protection Override Switch is in the ON position, the engine will perform as though there are no active derates or no active shutdowns. If the engine has already had a shutdown, the engine can be restarted. The alarm conditions and the events will continue to function normally.When the Engine Protection Override Switch is placed in the ON position, an event will be logged in the ECM.
