Monitoring System
If the Shutdown mode has been selected and the
warning indicator activates, engine shutdown
may take as little as 20 seconds from the time the
warning indicator is activated. Depending on the
application, special precautions should be taken
to avoid personal injury. The engine can be re-
started following shutdown for emergency ma-
neuvers, if necessary.
NOTICE
The Engine Monitoring System is not a guarantee
against catastrophic failures. Programmed delays
and derate schedules are designed to minimize false
alarms and provide time for the operator to stop the
engine.
The following parameters are monitored:
• Engine speed/timing
• Engine temperature and pressures sensors
• Atmospheric pressure (Barometric pressure)
• Fuel temperature
• Battery voltage
