3412E & C30 MARINE ENGINE Caterpillar

System Configuration Parameters

Usage:

System configuration parameters are parameters that affect emissions, power of the engine, and application specific features. 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. You must reprogram the system configuration parameters if the ECM is replaced and/or reprogram the engine rating. You do not need to reprogram the system configuration parameters if you replace the personality module. Proper values for the parameters are available on the Caterpillar Electronic Technician (Cat ET). Certain configuration parameters are also stamped on the engine information plate.

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

Parameter Descriptions

Rating Number

This parameter 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.

Equipment ID

This parameter allows the customer to enter a description into the ECM in order to identify the engine and/or 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.

Engine Serial Number

This parameter should be programmed 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 should be programmed into the new ECM.

Engine Location

This parameter is used to identify the location (center, port, or starboard) of each engine.

Fuel to Air Ratio Mode

The ECM controls the delivery of fuel to the engine. The electronic controls eliminate the mechanical fuel air ratio control. The electronic control of the fuel air mixture provides the optimum performance of the engine.

There are three different settings for the Fuel to Air Ratio Mode. The setting depends on the characteristic of operation that is desired by the customer. The default setting provides a balance between the emissions and the performance of the engine. Fuel to Air Ratio Mode can be set to the following settings.

* Level 1 (leanest mixture)

* Level 2 (Default)

* Level 3 (richest mixture)

Low Idle Speed

This parameter is the minimum allowable operating speed for the engine.

Maximum Trolling Engine Speed

This parameter sets the high idle limit to the programmed value when the vessel is in trolling mode. The value must be higher that the programmed Low Idle Speed and the Slow Vessel Speed.

Transmission Oil Temperature High Set Point

This parameter can be programmed to any value in the available range. The event code for the transmission oil temperature will be active when the transmission oil temperature exceeds the set point.

Transmission Oil Pressure High Set Point

This parameter can be programmed to any value in the available range. The event code for the transmission oil pressure will be active when the transmission oil pressure exceeds the set point.

Transmission Oil Temperature Sensor

This parameter can be programmed to either Installed or Not Installed.

Transmission Oil Temperature Sensor

This parameter can be programmed to either Installed or Not Installed.

Fuel Correction Factor

This parameter is available to fine tune all fuel data that will be stored in the future by the ECM. Caterpillar recommends changing this factor only after a significant operating interval that includes a comparison of actual tank fuel economy to the fuel economy that is recorded in the ECM. The operating interval should also reflect normal engine operation. The Fuel correction Factor is a percentage that is programmable in 0.5 percent increments.

The following formula is used to determine the fuel correction factor (FCF):

* new FCF = old FCF + [(100 + old FCF ) x error]/100

The old FCF is the FCF that is currently programmed in the ECM.

The following formula is used to determine the error:

* error = [(actual fuel economy - economy calculated by ECM)/actual fuel economy] x 100

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.

Engine Monitoring Mode

This parameter determines the level of action taken by the ECM. If Engine Monitoring Mode is programmed to "Warning", the operator will be warned of a potential problem. If Engine Monitoring Mode is programmed to "Derate", the ECM will derate engine power in order to prevent engine damage.

Coolant Level Sensor

This parameter can be set to either "Installed" or "Not Installed".

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 due reset 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.

Engine Oil Capacity

This parameter should be programmed to the capacity of the engine oil.

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.
