Configuration Parameters
Configuration parameters concern various engine features. Some parameters can affect the performance of the engine. Most of the parameters may be programmed with an 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 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 ET service tool 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 “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.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 “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".Air Shutoff
Note: This is an optional feature.The air shutoff uses a plate that rotates on a shaft in order to shut off 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.
The operator manually activates the air shutoff with the emergency air shutoffs on the engine. It is necessary to activate both of the air shutoffs in order to shut down the engine.Both of the air shutoffs must be reset before the engine can be restarted.

Reset knob for the air shutoff
To reset the air shutoff, turn the reset knob to the "OPEN" position.Ensure that both of the air shutoffs are reset.Cold Cylinder Cutout
Note: This feature can be enabled or disabled with an
