Operation and maintenance manual

Indicator Lamps
• Shutdown lamp
• Warning lamp
• Wait to start lamp
• Low oil pressure lamp (On solid) and engine oil
reset lamp (Flashing)
For information, refer to this manual, “Monitoring
System (Table for the Indicator Lamps)” for the
sequence of operation of the shutdown lamp and the
warning lamp.
The function of the wait to start lamp is automatically
controlled at engine start-up.
The low oil pressure lamp has two functions.
• The low oil pressure lamp is controlled by the
engine ECM. If low oil pressure is detected, the
lamp will be illuminated on solid. The reason for
the illumination of the low-pressure lamp should
be investigated immediately.
• Low oil pressure lamp flashing, an engine oil
change is required. The lamp must be reset, refer
to this Operation and Maintenance Manual,
“Engine Oil and Filter - Change” for more
information.
All lamps will illuminate for 2 seconds in order to
check that the lamps are functioning when the
keyswitch is turned to the ON position. If any of the
lamps stay illuminated, the reason for illumination
should be investigated immediately.
Aftertreatment Lamps
For information on the aftertreatment lamp, refer to
this Operation and Maintenance Manual, “Diesel
Particulate Filter Regeneration”.

Monitoring System
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
• Engine speed/timing
• Fuel temperature
• Atmospheric pressure (Barometric pressure)
• Water in fuel switch
• Inlet temperature of the diesel oxidation catalyst
• Inlet temperature of the diesel particulate filter
• Differential pressure in the diesel particulate filter
• The amount of soot in the diesel particulate filter
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 in order to
alert the operator that one or more of the engine
parameters is not within normal operating range.
““Derate””
The orange “Warning” lamp will turn “ON” and the red
shutdown lamp will be flashing. After the warning, the
engine power will be derated. The warning lamp will
begin to flash when the derating occurs.
