If the Warning/Derate/Shutdown mode has been
selected an
d the warning indicator activates,
bring the engine to a stop whenever possible. De-
pending on the application, special precautions
should be t
aken to avoid personal injury.
The engine can be programmed to the following
modes:
“Warning”
The “Warning” lamp and the warning signal (orange
lamp) turn “ON” and the warning signal is activated
continu
ously in order to alert the operator that one or
more of the engine parameters is not within normal
operating range.
“Warning/Derate”
The “ Di
agnostic” lamp turns “ON” and the warning
signal (red lamp) is activated. After the warning, the
engine power will be derated. The warning lamp will
begin t
o flash when the derating occurs.
The engine will be derated if the engine exceeds
prese
t operational limits. The engine derate is
achieved by restricting the amount of fuel that is
available for each injection. The amount of reduction
of fu
el 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
redu
ction in engine power.
“Warning/Derate/Shutdown”
The “Diagnostic” lamp turns “ON” and the warning
signal (red lamp) is activated. 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
af
ter 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

T
he engine may shut down again in as little as 20
seconds.
If there is a sig
nal for low oil pressure or for coolant
temperature, there will be a two second delay in
order to verify the condition.
For each of the programmed modes, refer to
Troubleshooting Guide, “Indicator Lamps” for more
