Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
Parameter Descriptions
"Rating Configuration"
The performance maps in the software
"Rated Real Genset Power"
The output power of the engine in kilowatts
"Rated Apparent Power"
The kVA rating of the engine
"Rated Frequency"
The line frequency of the generator
"Rating Number"
The Rating number corresponds to the selected set of performance maps for the application. This selected set of performance maps comes out of several unique sets of maps that may be resident in the flash file. The dealer and/or the OEM will need to select the appropriate rating tier, if more than one rating tier is present. The rating tier is A through E.
"Rated Engine Speed"
The optimum speed of the engine
"Engine Serial Number"
The engine serial number must be programmed to match the engine serial number that is stamped on the engine information plate. The engine serial number is not preprogrammed on a replacement ECM.
"Equipment ID"
This parameter allows the customer to enter a description into the ECM in order to identify the installation. A maximum of 17 characters can be entered in the field.
"Part Number of the Flash File"
The part number of the flash file is programmed into the software.
"The Release Date of the Flash File"
The release date of the flash file is programmed into the software.
"ECM Serial Number"
The ECM serial number is stored in the memory of the ECM.
"Total Tattletale"
The total tattletale counts the number of changes to system parameters.
"Low Idle Speed"
The parameter defines the low idle rpm.
"Engine Acceleration Rate"
The maximum ramp rate in order to reach desired engine speed.
"Engine Speed Droop"
This parameter allows the engine to operate in a load sharing system.
"Droop Mode Selection"
This parameter allows the customer to select droop or isochronous mode.
"Governor Gain Factor"
This parameter is used in determining the engine's rate of response to an engine load.
"Governor Minimum Stability Factor"
This parameter eliminates steady state speed error. The parameter is used by the ECM when the steady state speed error is less than 20 rpm.
"Governor Maximum Stability Factor"
This parameter eliminates steady state speed error. The parameter is used by the ECM when the steady state speed error is greater than 20 rpm.
"(FLS)" Full Load Setting
"FLS" is a number that represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information plate. Only change this value if the engine is rerated or if a new ECM is installed. Factory passwords are required.
"(FTS)" Full Torque Setting
"FTS" is similar to "FLS". Only change this value if the engine is rerated or if a new ECM is installed. Factory passwords are required.

Note: Compare the FLS and the FTS from the ECM with the values that are listed on the Engine Information Plate. The FLS and the FTS should only be changed because of a mechanical change in the engine. The use of the wrong parameters could cause damage to the engine. The use of the wrong parameters may also void the Caterpillar warranty.
