C18 Marine Auxiliary Engines Caterpillar

System configuration parameters are parameters that affect emissions and power of the engine applications. Default values for the parameters are programmed at the factory. Some parameters may be changed by the customer in order to suit the needs of the specific application. System configuration parameters consist of "Selected Engine Rating Parameters", "ECM Identification Parameters", "Security Access Parameters", "Engine/Gear Parameters", "I/O Configuration Parameters" and "System Parameters". The "ECM Identification Parameters" must be programmed if the ECM is replaced and/or you reprogram the engine rating. If a new personality module is flashed, it is not necessary to reprogram the "ECM Identification Parameters". Proper values for these parameters are available on the electronic service tool. Certain configuration parameters are also stamped on the engine information plate.

Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.

Parameter Descriptions

"Rating Configuration"

The "Rating Configuration" is defined by 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

"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.

"Engine Serial Number"

Program the "Engine Serial Number" to match the engine serial number that is stamped on the engine information plate. If the ECM is replaced, the engine serial number from the engine information plate must be programmed into the new ECM.

"Equipment ID"

"Equipment ID" allows the customer to enter a description into the ECM in order to identify the vessel. 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.

"Personality Module Part Number"

The "Personality Module Part Number" is the part number in the Caterpillar system that indicates the software version that currently resides in the engine ECM.

"Personality Module Release Date"

The "Personality Module Release Date" is the date of release for the software in the personality module.

"ECM Serial Number"

The "ECM Serial Number" is stored in the memory of the ECM. The "ECM Serial Number" can be accessed by the use of the service tool.

"Total Tattletale"

The "Total Tattletale" parameter counts the number of changes to system parameters.

"Low Idle Speed(optional)"

"Low Idle Speed" is the minimum allowable operating speed for the engine.

"Engine Acceleration Rate"

"Engine Acceleration Rate" is the maximum ramp rate in order to reach desired engine speed.

"Engine Speed Droop"

The "Engine Speed Droop" determines the change in the reduction of engine speed at full load from the engine speed at no load. Droop can be adjusted for stability of engines with different rates of speed changes. "Engine Speed Droop" allows the operator to equalize the load between engines that are operating in parallel.

"Droop Mode Selection"

"Droop Mode Selection" allows the customer to select either droop or isochronous mode.

"Governor Gain Factor"

The "Governor Gain Factor" is a parameter that is used in determining the engine's rate of response to an engine load.

"Governor Minimum Stability Factor"

"Governor Minimum Stability Factor" functions in order to eliminate 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"

"Governor Maximum Stability Factor" functions in order to eliminate 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. Factory passwords are required.

"FTS" (Full Torque Setting)

"FTS" is similar to "FLS". Factory passwords are required.

"Injector Codes"

Note: The injector codes are not part of the "Configuration" screen on the electronic service tool. "Injector Codes Calibration" can be found under "Calibrations" in the "Service" menu on the electronic service tool.

The injector code is a number that is found on each of the unit injectors. The ECM uses this number to compensate for manufacturing variations between individual injectors. If you replace any of the unit injectors, you must reprogram the code for the new injectors. Also, if you replace the ECM, you must reprogram all of the injector codes.

"Customer Password # 1"

This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.

"Customer Password # 2"

This parameter allows the customer to lock out certain parameters by entering a password. Customer passwords must be used to unlock any parameters that are protected by customer passwords before the parameter can be changed. Factory passwords are required if this password is lost.

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.

Monitoring System

The monitoring system determines the level of action that is taken by the ECM in response to a condition that can damage the engine. When any of these conditions occur, the appropriate event code will trip. The following table represents the conditions that are monitored and the programmable trip points for each of the conditions:

The "Low Coolant Temperature " monitoring will not wait in order for the engine to start running. The "Trip Delay" start-up begins when the ECM powers up. For EPG engines, low coolant temperature indicates that a water jacket may not be functioning.
