Customer System Overview 3 Customer System Overview 3.1 Customer Configuration Parameters Customer configuration parameters are ECU software settings that the customer can change in order to suit the needs of the specific application. These parameters are changed within the configuration screen in Caterpillar Electronic Technician (Cat ET). If a customer has more than one engine that should have the same configuration, the Fleet Configuration option is available in Cat ET to save the configuration settings to a file and download the settings to all subsequent engines that are to have the same configuration settings.
Default values for these parameters are set in the factory when the new ECU is flash programmed for the first time. The customer configuration parameters must be reprogrammed if the ECU is replaced and/or the engine rating is changed. These parameters do not need to be reprogrammed if the ECU is re-flashed with a latest version of software flash file. Refer to the Appendix sections for customer configuration parameters and monitoring system parameters for a complete list of supported programmable parameters.
Further definition of each parameter can be found within the section of the document that defines a software feature that uses the parameter to support installation or operation of that specific software feature. Customer configuration parameters in legacy product that are no longer supported: • Direct Fuel Control Mode • Engine Oil Weight (C-9 Engine) • Engine Power Trim Notes on Programming Parameters 1. Changing parameters protected by factory passwords may void Caterpillar warranty. Consult Industrial Application Support Center contacts before changing. 2.In order for the programmed values to change, the key switch (switched power only) must be cycled off and on.
3.If there is an interlock error (personality module mismatch), then the programmed parameters will not change. It may appear that the parameters are changed, but they will not change until the “personality module mismatch” code is cleared. 3.2 Customer Component Overview Industrial engines offer a set of application features that can be specified by the customer to meet the application operating requirements. Application of these features requires a different set of customer installed components based on the features selected. Each installation requires the minimum set of customer installed components listed in Table 1.
Customer installed components for application specific features are listed in Table 2. See the section identified with each component for more information on component usage and requirements. A P P L I C A T I O N A N D I N S T A L L A T I O N G U I D E 15
