This is the first of fourshutdowns allowed by the engine.Note: The genset controller’s 10-minute run timelimitation is still active within the 180-minute engine runtime limit. Thus, up to seventeen restarts by the gensetcontroller are possible within the 180-minute enginecontrolled run time.■ The engine may be restarted, but the run time islessened to 30 minutes. At the 30-minute mark, theengine shuts itself down. This is the second of fourallowed shutdowns. The genset controller’s 10-minuterun time limitation is still active. Thus, up to threerestarts by the genset controller are possible within the30-minute engine controlled run time limit. On the fourthshutdown, the engine controller will lock out the engine.The engine can only be unlocked by a Cummins servicetechnician.
