HOSE AS 1095760 - Caterpillar

System configuration parameters are parameters that are configured to specify the engine emissions levels, the power rating, and the specific application. Default values for the parameters are programmed at the factory. Some parameters may be changed in order to equip the engine for a specific application. The system configuration parameters must be reprogrammed if the Electronic Control Module (ECM) is replaced without using the "Copy Configuration" tool that is in Caterpillar Electronic Technician (ET). Reprogramming the system configuration parameters is not necessary if you update the ECM flash file. Certain configuration parameters are stamped into the engine information plate.Some parameters are protected by security passwords. Customer passwords or factory passwords may be required in order to change these parameters. Refer to Troubleshooting, "Customer Passwords" and Troubleshooting, "Factory Passwords" for details.Note: Factory passwords are only available to service technicians from an authorized Caterpillar Dealership. Customers of Caterpillar do not have access to the Caterpillar Factory Password System (FPS). If the parameters that are protected with factory passwords are changed without authorization from Caterpillar, the repair may not be covered under the Caterpillar warranty.Refer to Systems Operation/Testing and Adjusting, "Electronic Control System Parameters" for additional information.Table 1 is a list of the parameters that can be configured for G3520B Engines. The parameters are programmed into the ECM via the Cat ET. The values of the parameters can be viewed on the "Configuration" screen of Cat ET.ECM Identification Parameters
Equipment ID
The customer can assign an "Equipment ID" for identification for the engine application.Engine Serial Number
The engine serial number is programmed into the ECM at the factory. The number is stamped on the engine information plate.Timing Control
These timing parameters allow the customer to program ignition timing electronically in order to meet the needs for specific applications and installations.Note: The actual ignition timing at a given instance may vary from the desired timing value. This variance is due to variations in the engine speed, engine load, or detonation.First Desired Timing
The "First Desired Timing" is determined with the methane number of the primary fuel that is used. Use the Engine Performance Sheet, "Fuel Usage Guide". The ECM selects the "First Desired Timing" when the timing select switch creates an open circuit for terminal J1-20 at the master ECM.
Note: The desired timing should be determined by using the Caterpillar Software, LEKQ6378, "Methane Number Program" with the results that are from the fuel analysis. Use of only the data from the gas analysis can result in incorrect settings.Second Desired Timing
The "Second Desired Timing" is determined with the methane number of the alternate fuel that is used and the Engine Performance Sheet, "Fuel Usage Guide". The ECM selects the "Second Desired Timing" when the timing select switch creates a short circuit to ground for terminal J1-20 at the master ECM.If an alternate fuel is not used, enter the same timing value for the "Second Desired Timing" parameter that is entered in the "First Desired Timing" parameter.Desired Engine Timing Offset
This feature provides the offset of engine ignition timing to
