Use of Cat ET
PC requirements for Cat ETFor information on connecting Cat ET to the engine Electronic Control Module (ECM), refer to your engine Troubleshooting manual.Recommendations for Programming the System Configuration Parameters
For descriptions of the parameters, refer to Systems Operation, "Electronic Control System Parameters". The values of the parameters can be viewed on the "Configuration" screen of Cat ET.Programmable parameters enable the engine to be configured in order to meet the requirements of the application. The system configuration parameters must be programmed when the application is installed. Perform this programming before the initial engine start-up.Data from a gas analysis and data on engine performance are required. The data determines the correct settings for the fuel quality and for the specific gravity of the gas. Incorrect programming of parameters may lead to complaints about performance and/or to engine damage.If an ECM is replaced, the appropriate parameters must be copied from the original ECM. The copy can be done with the "Copy Configuration" feature of Cat ET. Alternatively, the settings can be recorded on paper and then programmed into the new module.
Changing the parameters during engine operation can cause the engine to operate erratically. Erratic operation can cause engine damage.Only change the settings of the parameters when the engine is STOPPED.
Changing the Settings of the Monitoring System
For descriptions of the monitoring system parameters, refer to Systems Operation, "Engine Monitoring System".To change the settings of the parameters, use Cat ET and select the "Service/Monitoring System" screen.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.Refer to Systems Operation for the default setting for the system configuration parameters.
