Monitoring System
(Engine)
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:
• Coolant temperature
• Intake manifold air temperature
• Intake manifold air pressure
• Oil pressure
• Pressure in the fuel rail
• Fuel temperature
• Fuel filter differential pressure
• Water in fuel
• Engine speed/timing
• Atmospheric pressure (Barometric pressure)
• The Inlet pressure and outlet pressure of the NOx
reduction system
• The differential pressure within the NOx reduction
system
• Temperature of the NOx reduction system
• The amount of soot in the Diesel particulate filter
