SEAL ASSEM. 3G2286 - 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.
Programmable features monitor the following conditions:
Coolant temperature
Inlet air temperature
Engine oil pressureProgrammable 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"
"Warning/Derate"
"Warning/Derate/Shutdown""Warning"
The "DIAGNOSTIC" lamp and the warning signal (red lamp or buzzer) 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."Warning/Derate"
The "DIAGNOSTIC" lamp turns "ON" and the warning signal (red lamp or buzzer) is activated. After the warning, the engine will derate rpm and power. The warning lamp will begin to flash when the derating occurs.When the engine is fully derated, the engine power is limited to 90 kW (120 hp). The vehicle speed is limited to 72 km/h (45 mph)."Warning/Derate/Shutdown"
The "DIAGNOSTIC" lamp turns "ON" and the warning signal (red lamp or buzzer) is activated. After the warning, the engine will derate rpm and power. The engine will continue to derate rpm 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 coolant loss, there will be a 10 second delay in order to verify the condition. The system will derate the engine rpm for 40 seconds before the engine will shut down if the engine has been programmed to shut down.If there is a signal for low oil pressure or for coolant temperature, there will be a two second delay in order to verify the condition. The system will derate the engine rpm for 30 seconds before the engine will shut down if the engine has been programmed to shutdown.Engine Shutdown Override Switch (If Equipped)
Note: This option is available only for the C9 Mass Transit Bus Engine.The operator can override a programmed engine shutdown if the cause of the shutdown is low oil pressure, high coolant temperature, or low coolant level. The driver may use the engine shutdown override switch in order to safely park the vehicle before the engine shutdown. When the driver pushes the engine shutdown
