FITTING 3B9054 - 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 Cat Electronic Technician (ET). Some of the parameters require a password in order to be programmed.Note: For information on programming the parameters, use Cat ET 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 will indicate that the parameter is unavailable when the parameter is selected. Table 1 is a list of typical configuration parameters.

( 1 ) Jacket water aftercooling or separate circuit aftercoolingThe following parameters are programmed at the factory to zero:
"Crank Duration"
"Maximum Number Of Crank Cycles"The zero settings prevent the Electronic Control Module (ECM) from engaging the starting motors. The settings must be reprogrammed before the engine will crank.Ensure that the "Air Shutoff" and the "Ether Control" parameters are "Enabled/ON" (if equipped). If the engine does not have these options, ensure that these two 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 zero seconds. Otherwise, the prelube pump will not cycle. If the engine is not equipped with Prelube, the parameter must be programmed to zero.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. Free configuration feature enables the customer to tailor the programmable setpoints to the requirements of the installation during the 100 hours. Exceptions are "Fuel Limit" and engine rating.Air Shutoff
Note: If equipped.The air shutoff uses a moving plate to block inlet air to the aftercooler. The engine stops because of the restricted air supply to the combustion chamber. The air shutoff only actuates for the following conditions:
The Emergency Stop button is pressed.
An overspeed shutdown occurs.Both of the air shutoffs must be reset before the engine can be
