NOTICE
The Engine Monitoring System is not a guarantee
a
gainst 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
