Programmable Options and
Systems Operation
If the Warning/Derate/Shutdown mode has been
selected and the warning indicator activates,
bring the engine to a stop whenever possible. De-
pending on the application, special precautions
should be taken to avoid personal injury.
The engine can be programmed to the following
modes:
““
Warning
””
The orange
“
Warning
”
lamp will turn
“
ON
”
and the
warning signal is activated continuously to alert the
operator that one or more of the engine parameters is
not within normal operating range.
““
Derate
””
The orange
“
Warning
”
lamp will be
“
Flashing
”
. After
the warning, the engine power will be derated. The
warning lamp will begin to flash when the derating
occurs.
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 fuel reduction
dependents 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 be
“
Flashing
”
. 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. After shutdown the
red stop lamp will illuminate. The engine can be
restarted after a shutdown for use in an emergency.
A shutdown of the engine after been triggered is
immediate. The engine can be restarted after a
shutdown for use in an emergency. However, the
cause of the initial shutdown may still exist.
If there is a signal for high coolant temperature, there
will be a 2 second delay to verify the condition.
If there is a signal for low oil pressure, there will be a
2 second delay to verify the condition.
