ROLLER GP-TRACK 1286898 - Caterpillar

Separate timers are used in the ECM for each response that is associated with a parameter. If a trip point is exceeded, the timer for that event is started.For example, the warning for "High Engine Coolant Temperature E017 (1)" can be set to 95° C with a five second delay. The timer starts counting if the coolant temperature exceeds 95° C. If the temperature is not reduced to less than 95° C within five seconds, the event becomes active and the event is logged.Conditions for Parameters
Some of the programmable parameters are dependent on the status of a ECM output before the parameters are allowed to function. Some of the parameters are allowed to function after the crank terminate relay has been energized for more than 30 seconds. Other parameters are allowed to function after the output for the fuel control relay is energized. Some parameters are not dependent upon any conditions.The conditions are designed to eliminate false events during start-up if the customer has programmed a delay time to zero. The conditions are listed in Table 3.

Conditions for Activation for Monitoring the Parameters
Parameter Condition
"Low System Voltage" None
"High Engine Coolant Temperature" The crank terminate relay is energized for more than 30 seconds.
"Low Engine Coolant Temperature" None
"Engine Overspeed" None
"High Engine Oil Temperature" The crank terminate relay is energized for more than 30 seconds.
"High Oil Filter Differential Pressure"
"Low Oil Filter Differential Pressure"
"High Fuel Temperature"
"Low Fuel Pressure" The fuel control relay is energized.
"High Engine Oil to Engine Coolant Differential Temperature" The crank terminate relay is energized for more than 30 seconds.
"Low Gas Fuel Differential Pressure" The fuel control relay is energized.
"High Gas Fuel Differential Pressure"
"High System Voltage" None
"High Inlet Air Temperature at Low Engine Load" The crank terminate relay is energized for more than 30 seconds.
"High Inlet Air Temperature at High Engine Load"
"High Fuel Pressure" The fuel control relay is energized. Use care when you program the trip points and the delay times. Ensure that the response of the ECM is correct for the application. The monitoring system will accept any settings within the ranges.If the trip point for a shutdown is programmed to activate before the trip point for a warning, the engine will shut down and the warning will not be activated.Programmable Parameters of the Integrated Temperature Sensing Module
The Integrated Temperature Sensing Module (ITSM) monitors the temperatures of the cylinder exhaust ports, of the inlets of the turbocharger turbine, and of the outlets of the turbocharger turbines.If a temperature exceeds an acceptable range, the ITSM can initiate a "" or "SHUTDOWN". Both of the responses are available for all of the parameters. Use Cat ET to perform the following activities:
Select the available responses.
Program the level for monitoring.
Program delay times for each response.Note: To initiate the responses, the ITSM sends commands to the ECM via the Cat Data Link. If the connection between the ITSM and the ECM is not correct, the ITSM cannot initiate any response.The default settings for the parameters are programmed at the factory. To accommodate unique
