Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
Parameter Descriptions
Equipment ID
This parameter allows the customer to enter a description into the ECM in order to identify the engine's application. A maximum of 17 characters can be entered in the field.
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 into a replacement ECM.
ECM Serial Number
The serial number of the ECM that is stored in the ECM memory
Software Group Part Number
The part number of the flash file that is currently installed in the ECM
Software Group Release Date
The release date of the flash file that is currently installed in the ECM
Software Group Description
The description of the application for the flash file that is currently installed in the ECM
Rating Number
The rating number corresponds to the selected set of performance maps that has been selected for this application. There may be more than one set of performance maps that are available for this engine. All of the maps are resident in the flash file for the engine.
Rated Frequency
The line frequency of the generator set
Rated Engine Speed
The optimum speed of the engine
Rated Real Genset Power
The output power of the generator set in kilowatts
Rated Apparent Genset Power
The kVA rating of the generator set
Rating Configuration
The performance maps in the software
Test Spec
This is the engine's "Test Specifiction Number". Use this number to retrieve data that is related to the engine's specifications from the Technical Marketing Information System (TMI). The following information can be retrieved from TMI:
- "As shipped consists"
- "Engine test specifications"
- "Systems data"
- "Physical data"
- "Gasket kit data"
- "Reman parts"
- "Performance data"
A link to TMI Web can be found on the web site for the Service Information System (SIS).
Engine Acceleration Rate
This parameter defines the maximum rate of engine acceleration.
Low Idle Speed
This parameter defines the low idle rpm of the engine.
Engine Speed Droop
This parameter enables the engine to be operated in a load sharing system.
Droop/Isochronous Switch Enable
This parameter defines the installation status of a switch that is used to select droop or isochronous mode.
Droop Mode Selection
This parameter allows the customer to select droop or isochronous mode.
Remote Emergency Stop (E-Stop) Switch Input Type Configuration
This parameter sets the installation status and the configuration of the emergency stop switch.
Desired Speed Input Configuration
This parameter defines the type of signal that is used for throttle control. This parameter will be used while a valid signal is present at the expected input.
The following input types are available:
PWM - A Pulse Width Modulated signal (PWM) is received via terminal P1-66 at the ECM connector.
CAN Input - A J1939 signal is received via the CAN data link.
0 - 5 VDC - An analog signal is received via terminal P1-15 at the ECM connector.
Secondary Desired Speed Input Configuration
This parameter defines the type of signal that is used as a secondary throttle control. If the signal for this input becomes unavailable, the ECM will revert to this type of signal for the throttle control. Refer to "Desired Speed Input Configuration" for the input types that are available.
Fuel Enable Input Configuration
This parameter allows the selection for the type of input that is used to enable the fuel for the engine.
Secondary Fuel Enable Input Enable Status
This parameter sets the installation status of a secondary switch that can be used to enable the fuel for the engine.
Coolant Level Sensor
This parameter can be set to either "Installed" or "Not Installed".
Engine Oil Temperature Sensor
This parameter can be set to either "Installed" or "Not Installed".
Engine Oil Capacity
Program this parameter to the capacity of engine oil for the engine.
Maintenance Indicator Mode
The ECM records data that is related to equipment maintenance. The ECM will activate the maintenance indicator lamp when scheduled maintenance is due. The maintenance indicator lamp can be reset by actuating the maintenance clear switch. The maintenance interval may be based on operating hours or fuel consumption. The ECM provides information that pertains to maintenance intervals and the last maintenance that was performed.
PM1 Interval
This parameter allows the customer to define the maintenance interval if "Maintenance Indicator Mode" is programmed to one of the manual options. Refer to the Operation and Maintenance Manual for more information.
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 is used by the ECM to offset the steady state speed error when the steady state speed error is less than 20 rpm.
Governor Maximum Stability Factor
This parameter is used by the ECM to offset the steady state speed error when the steady state speed error is greater than 20 rpm.
FLS
This parameter represents the fuel system adjustment that was made at the factory in order to fine tune the fuel system to the engine. 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 has been installed. Factory passwords are required to change this parameter.
FTS
This parameter is another parameter that represents a fuel system adjustment that was performed at the factory in order to fine tune the fuel system to this engine. Only change this value if the engine is rerated or if a new ECM has been installed. Factory passwords are required to change this parameter.
Total Tattletale
The total tattletale counts the number of changes to system parameters.
