Operation and maintenance manual

The engine will be derated if the engine exceeds
preset operational limits. The engine derate is
achieved by restricting the amount of fuel that is
available for each injection. The amount of this
reduction of fuel is dependent on the severity of the
fault that has caused the engine derate, typically up
to a limit of 50%. This reduction in fuel results in a
predetermined reduction in engine power.
““Shutdown””
The orange warning will turn “ON” and the red
shutdown lamp will also turn “ON” . After the warning,
the engine power will be derated. The engine will
continue at the rpm of the set derate until a shutdown
of the engine occurs. The engine can be restarted
after a shutdown for use in an emergency.
A shutdown of the engine may occur in as little as 20
seconds. The engine can be restarted after a
shutdown for use in an emergency. However, the
cause of the initial shutdown may still exist. The
engine may shut down again in as little as 20
seconds.
If there is a signal for high coolant temperature, there
will be a 2 second delay in order to verify the
condition.
If there is a signal for low oil pressure, there will be a
2 second delay in order to verify the condition.
For information on the operation of the warning
lamps and the shutdown lamp, refer to this Operation
