Changing the Settings of the Monitoring System
Use the following procedure to change settings of the parameters:
Select the "Service/Monitoring System" screen on Cat ET.
Highlight the desired parameter. Then click the "Change" button in the lower left corner of the screen.The "Change Monitor System" screen will appear.
Change the "State" of the parameter.
Set the "Trip Point" and the "Delay Time" according to the "Allowed Values" that are displayed 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.Note: If a factory password is required, the "Enter Factory Passwords" screen will appear. Refer to Troubleshooting, "Factory Passwords" for information that is related to obtaining factory passwords.The new settings will be effective immediately.Default Settings of the Monitoring System
Examples of the default settings for the parameters are listed in Table 1. The values may have changed. Use the Cat ET to determine the programming for your engine. Many of the items can be reprogrammed in order to accommodate the requirements of individual sites.

Shutdown On     Factory     20 °C    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 5 seconds, the event becomes active and the event is logged.
