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 turbines 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 applications and sites, the parameters may be reprogrammed with Cat ET. The screens of Cat ET provide guidance for changing trip points.Table 2 lists default examples of the values for the parameters. However, the values may have changed. Use Cat ET to determine the programming for your engine. The items can be reprogrammed in order to accommodate the requirements of individual sites.Use care when you program the trip points and the delay times. Ensure that the response of the ITSM is correct for the application. The monitoring system will accept any setting within the ranges.If the trip point for a shutdown is lower than the trip point for a warning, the warning will not be activated.
