815279T Mercury REGULATOR, Voltage

System configuration parameters are parameters that affect emissions, power of the engine, and other features that define the characteristics of the engine subsystems. The parameters are preprogrammed at the factory. You may need to reprogram the system configuration parameters if the Electronic Control Module (ECM) is replaced and/or if you reprogram the engine rating. You do not need to reprogram the system configuration parameters if you replace the flash file. Caterpillar Electronic Technician (ET) can be used to view the values for these parameters. Certain system configuration parameters are stamped on the engine information plate.Parameter Descriptions
ECM Identification Parameters
Equipment ID
"Equipment ID" allows the customer to enter a description into the ECM in order to identify the installation. A maximum of 17 characters may be entered in the field. This parameter is only for reference by the customer. This parameter is not required.Engine Serial Number
Program the engine serial number to match the engine serial number that is stamped on the engine information plate.Note: When you are requesting factory passwords, always use the engine serial number that is programmed into the ECM.ECM Serial Number
The ECM serial number is stored in ECM memory. The ECM serial number can be accessed using Cat ET.Software Group Part Number
This parameter identifies the part number of the flash file that is currently installed in the ECM.Software Group Release Date
This parameter identifies the release date of the flash file that is currently installed in the ECM.Software Group Description
This parameter identifies the description of the application for the flash file that is currently installed in the ECM.Selected Engine Rating
Rated Power
This parameter specifies the rated power of the engine.Rated Peak Torque
This parameter specifies the rated peak torque of the engine.Speed Control
Low Idle Speed
This parameter specifies the low idle speed setting for the engine.High Idle Speed
This parameter specifies the maximum high idle speed that is allowed for the engine.Engine Configuration Parameters
Ether Solenoid Configuration
This parameter must be programmed to "Continuous Flow" for a continuous flow solenoid and valve assembly.Engine Retarder Enable Command
This parameter is enabled in order to define the installation status of compression brakes for the engine.Low System Battery Voltage Elevated Idle
This parameter enables operation of the elevated idle function if a low battery condition is detected by the ECM. Engine Warmup Elevated Idle Feature Enable Status
This feature allows a strategy for elevated idle to be enabled during cold engine operation.Engine Idle Shutdown
This feature is used to shut down the engine during periods of extended engine idling. This feature will save the engine from the accumulation of service hours and the feature will conserve fuel. Engine Idle Shutdown Minimum Ambient Air Temperature
The idle shutdown feature will not be enabled by the ECM unless the ambient air temperature is above this setting.Engine Idle Shutdown Maximum Ambient Air Temperature
The idle shutdown feature will not be enabled by the ECM unless the ambient air temperature is below this setting.Engine Idle Shutdown Enable Status
This parameter is used to enable the idle shutdown feature.Engine Idle Shutdown Delay Time
This parameter defines the idle time for the machine prior to an automatic shutdown of the engine.Engine Idle Shutdown Ambient Temperature Override Enable Status
This parameter is used to enable the shutdown parameters that are used for the minimum and maximum ambient air temperature. Delayed Engine Shutdown
Illustration 1 g02138396
Position of the keyswitch for an immediate engine shutdown
The operator can defeat the delay for the engine shutdown by turning the keyswitch past the OFF position. This position of the keyswitch will close the momentary contacts that initiate an immediate shutdown.Delayed Engine Shutdown Enable Status
This feature allows the engine to continue to run after the operator has turned the keyswitch to the OFF position. This feature allows time for components in the engine compartment to cool down to an acceptable level prior to shutting down the engine.Delayed Engine Shutdown Maximum Time
This parameter defines the maximum amount of time for the engine to run after the operator has turned the keyswitch to the OFF position.Aftertreatment Configuration
Factory Installed Aftertreatment #1 Identification Number
This number is stored in ECM memory. This number identifies the exhaust aftertreatment system for the engine ECM. This number is found on the Clean Emissions Module (CEM) identification plate.
