KIT-SEAL 1933088 - Caterpillar

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 restarted following shutdown for emergency maneuvers, if necessary.
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 catalystProgrammable 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. Depending 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 "flashing". After the warning, the engine power will be derated. 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 percent. 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 and Maintenance Manual, " Monitoring System (Table for Indicator Lamps)". For each of the programmed modes, refer to Troubleshooting Guide, "Indicator Lamps" for more information on Indicator Lamps. For more information or assistance for repairs, consult your Cat dealer.
