SEBU8726-03 35 Operation Section Monitoring System Indicator Lamps 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. Shutdown lamp Warning lamp Wait to start lamp Low oil pressure lamp (On solid) and engine oil reset lamp (Flashing) The following parameters are monitored: 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.
Coolant temperature Intake manifold air temperature Intake manifold air pressure The function of the wait to start lamp is automatically controlled at engine start-up. Oil pressure The low oil pressure lamp has two functions. Pressure in the fuel rail 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. Engine speed/timing Fuel temperature Atmospheric pressure (Barometric pressure) 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. 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 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.
Programmable Options and Systems Operation Aftertreatment Lamps For information on the aftertreatment lamp, refer to this Operation and Maintenance Manual, “Diesel Particulate Filter Regeneration”. 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. i04317185 Monitoring System 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. 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. 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.
