Changing the Settings of the Monitoring System
Use the following procedure to change settings of the parameters:
- Use Cat ET and select the "Service/Monitoring System" screen.
- Highlight the desired parameter. Then click on the "Change" button in the lower left corner of the screen.
The "Change Monitor System" screen will appear.
- Change the "State" to "On" or "Off".
- Set the "Trip Point" and the "Delay Time" according to the "Allowed Values" in the lower half of the screen.
- Click the "OK" button.
If a password is required, the "Enter Passwords" screen will appear. Enter the correct passwords and then click the "OK" button.
The new settings will be effective immediately.
The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always ON. This parameter cannot be turned off. If the system voltage decreases to the trip point or if the system voltage goes below the trip point, the ECM will generate a warning or a shutdown.
"High Engine Coolant Temperature"

Trip Points of the Engine Load for High Inlet Air Temperature
The trip points for these parameters can be programmed by the customer. The shutdown response is always ON. The shutdown response cannot be turned off. This feature provides a trip point between high engine load and low engine load. The trip point is used for events that involve high inlet air temperature. The trip point for the events is based on the engine load. The possible responses of the system include a warning or a shutdown.
If the load is greater than the trip point, the trip point for the "High Inlet Air Temperature at High Engine Load" event is used for the logging of the high inlet air temperature.
If the load is less than the trip point, the trip point for the "High Inlet Air Temperature at Low Engine Load" event is used for the logging of the high inlet air temperature.
"High Inlet Air Temperature at Low Engine Load"
The "Service/Configuration" screen of Cat ET defines the "High Inlet Air Temp Engine Load Set Point". The ECM can activate a warning or a shutdown if the inlet air temperature increases to the trip point or if the inlet air temperature exceeds the trip point during the low load operation that is defined.
"High Inlet Air Temperature at High Engine Load"

Separate timers are used in the ECM for each response that is associated with a parameter. If a trip point is reached, 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 reaches 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.
Some of the programmable parameters are dependent on the status of an 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 2.

| "Low System Voltage" | None |
| "High Engine Coolant Temperature" | The crank terminate relay is energized for more than 30 seconds. |

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, the inlets of the turbocharger turbine, and the outlets of the turbocharger turbines.
If a temperature exceeds an acceptable range, the ITSM can initiate a "WARNING" 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 3 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 programmed to activate before the trip point for a warning, the engine will shut down and the warning will not be activated.

Separate timers are used in the ITSM 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 the "High Exhaust Temperature" (E801 (1)) can be set to 655 °C with a 30 second delay. The timer starts counting if the exhaust port temperature of the number 1 cylinder reaches 655 °C. If the temperature is not reduced to less than 655 °C within 30 seconds, the event becomes active and the event is logged.
