INJECTOR GP-FUEL 2225972 - Caterpillar

A programmable engine monitoring system is provided. The Electronic Control Module (ECM) can monitor parameters. The ECM can initiate an action if a specific parameter for engine operation exceeds an acceptable range. Three possible actions from the ECM may be available: "", "DERATE" and "SHUTDOWN". All actions are not available for some parameters. The Cat® Electronic Technician (ET) is used to select the actions from the ECM. The Cat ET will program the level for monitoring and the delay times for each action.Note: The parameters must be programmed with the Cat ET when the customer requires any of the parameters to be different from the factory settings.Monitoring system parameters must be programmed with the Cat ET. In order to program the monitoring system parameters, select "monitoring" from the Cat ET menu. Screens in Cat ET provide guidance through the steps for programming in order to select the "OFF//DERATE/SHUTDOWN" options that are available for the selected parameter. Screens in Cat ET also provide guidance for changing "/DERATE/SHUTDOWN" setpoints. Some parameters will require a password to be programmed. Refer to the Cat ET and the Troubleshooting manual for additional information on programming the monitoring system parameters. The engine monitoring system is enabled after the engine is started. When the engine rpm exceeds a point that is 50 rpm below the low idle speed the ECM checks the parameter levels. The ECM checks the parameter levels in order to determine if the levels exceed the setpoints for the monitoring system.Any action of the monitoring system will log an event. These actions are "", "DERATE" or "SHUTDOWN". A warning event will still be logged if the setpoint is exceeded and these actions are turned off.Any failure of a sensor will result in the disabling of the corresponding portion of the monitoring system. There will be an active diagnostic for the failed sensor, but an event is not logged. Refer to Troubleshooting for additional information on sensors.
