STRAP 7W4975 - Caterpillar

Parameter Settings of the Engine Monitoring System
The default settings for the parameters are programmed at the factory. The delay time, trip point, and available ranges are listed in Table 1. Some parameters are not programmable in the field. These parameters and the applicable trip points are listed in Table 2.The parameter settings for the engine monitoring system can be viewed on Caterpillar Electronic Technician (ET), the Messenger display panel.Viewing or Changing the Settings of the Monitoring System
Use the following procedure in order to view the parameter settings and/or change the parameter settings when you are using Caterpillar Electronic Technician (ET):
Select the "Service/Monitoring System" screen on Cat ET. Note: Ensure that you select the correct ECM for the parameters that are being changed before continuing.
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 Testing and Adjusting, "Factory Password - Obtain" for information that is related to obtaining factory passwords.The new settings will be effective immediately.The Messenger display panel can also be used to change the following monitoring system trip points:
Low and high system voltage
High coolant temperature
High engine oil temperature
Low and high catalytic convertor intake gas temperatures
High catalytic convertor outlet gas temperature
High catalytic convertor differential gas temperature
Engine overspeed
High inlet air temperatureThe Trip Point and the Delay Time ranges are displayed in the lower half of the Messenger display screen.Parameters for the Programmable Monitoring System
