TEE 7X2459 - Caterpillar

Configuration parameters concern various engine features. Some parameters can affect the performance of the engine. Most of the parameters may be programmed with a Caterpillar Electronic Technician (ET) service tool. Some of the parameters require a password in order to be programmed.Note: For information on programming the parameters, use the appropriate Cat ET service tool and see the Service Manual, "Troubleshooting" module.Some parameters may not be available on all applications. If a parameter is not available the Cat ET service tool will indicate that the parameter is “unavailable” when the parameter is selected.The following parameters are programmed at the factory to “0”:
"Crank duration"
"Maximum number of crank cycles"The “0” settings prevent the Electronic Control Module (ECM) from engaging the starting motors. The settings must be reprogrammed before the engine will crank.Program both the primary ECM and the backup ECM.Ensure that these parameters (if equipped) are "Enabled/ON": "Air Shutoff", "Ether Control" and "Pilot House EMS". If the engine does not have these options, ensure that these parameters are "DISABLED/OFF".If the engine is equipped with prelube, the "Engine Prelube Duration" must be programmed to a value that is greater than “0” seconds. Otherwise, the prelube pump will not cycle. If the engine is not equipped with prelube, the parameter must be programmed to “0”.The engine will have either jacket water aftercooling or separate circuit aftercooling. The correct configuration of the aftercooling system must be programmed.No password is required for programming a new ECM during the first 100 hours of service life. This 100 hour “free configuration” feature enables the customer to tailor the programmable setpoints to the requirements of the installation. Exceptions are "Fuel Limit" and "Personality Module Mismatch".Parameter Descriptions
"Injector Codes"
Note: The injector codes are not part of the "Configuration" screen on the electronic service tool. "Injector Codes Calibration" can be found under "Calibrations" in the "Service" menu on the electronic service tool.The injector code is a number that is found on each of the unit injectors. The ECM uses this number to compensate for manufacturing variations between individual injectors. If you replace any of the unit injectors, you must reprogram the code for the new injectors. Also, if you replace the ECM, you must reprogram all of the injector codes."Fuel Ratio Control"
The "Fuel Ratio Control" limit controls the amount of fuel to air ratio by limiting the rack as a function of boost pressure, engine speed and altitude. The "Fuel Ratio Control" function permits an offset to be applied to the calculation for the altitude. The offset changes the fuel to the air ratio to a richer mixture or a leaner mixture."Rated Fuel Position"
This parameter is used to limit the engine power. A factory password is required to change this setting.Direct Fuel Control Mode
The "Direct Fuel Mode" allows the use of an external governor to control engine speed.The governor-to-engine interface is identical to that of the large line of Woodward “EG-XXX"” electrohydraulic actuators. These electrohydraulic actuators use the same drive signal and input impedance.Only governors that have been designed to
