Parameter Descriptions
"Equipment ID"
"Equipment ID" allows the customer to enter a description into the Electronic Control Module (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. If the ECM is replaced, the engine serial number from the engine information plate must be programmed into the new ECM.
"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 are 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.
Note: Factory passwords are required in order to change the "Rating Number".
"Top Engine Limit" (TEL)
 | |
| Illustration 1 | g00763900 |
"TEL" is a customer programmable parameter that defines the maximum allowable engine speed for maximum power. "TEL" can be programmed up to the maximum rated engine speed. "TEL" is defined along the engine's lug curve.
"Engine Accel. Rate"
"Engine Accel. Rate" determines the rate of change of the engine speed (acceleration or deceleration) during PTO operation. This rate of change is also used to achieve intermediate engine speed.
"PTO Mode"
"PTO Mode" allows the ECM to be programmed to either one of the two PTO configurations that are available.
"Ramp Up/Ramp Down" - When "PTO Mode" is programmed to "Ramp Up/Ramp Down", the ECM allows PTO operation with traditional features.
"Set/Resume" - When "PTO Mode" is programmed to "Set/Resume", the ECM allows PTO operation with enhanced features.
"Low Idle Speed"
"Low Idle Speed" is the minimum allowable operating speed for the engine. This parameter can be programmed between 600 and 1400 rpm.
"High Idle Speed"
| | |
| Illustration 2 | g00763900 |
"High Idle Speed" is the maximum no-load engine speed when the throttle or the PTO switch is in the maximum position.
Note: "High Idle Speed" cannot be programmed lower than "TEL".
"Intermediate Engine Speed"
"Intermediate Engine Speed" defines the speed for the engine when the intermediate engine speed switch is activated. This parameter can be programmed to any engine speed between "Low Idle Speed" and "TEL". Engine speed will increase or engine speed will decrease at the rate that is defined by the programmed value for "Engine Accel. Rate".
"Maximum Engine Torque Limit"
 | |
| Illustration 3 | g00817759 |
"Engine Torque Limit" can be used to limit torque output to the programmed value when the torque limit switch is activated.
"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 in order to change this parameter.
"FTS" (Full Torque Setting)
"FTS" is similar to "FLS". Factory passwords are required in order to change this parameter.
"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 on fuel consumption. The ECM provides information that pertains to maintenance intervals and the last maintenance that was performed.
"PM1 Interval"
"PM1 Interval" allows the customer to define the maintenance interval if "Maintenance Indicator Mode" is programmed to one of the manual options. Refer to the engine's Operation and Maintenance Manual for more information.
"Throttle Position Sensor"
Program the "Throttle Position Sensor" to "Installed" if a throttle position sensor is used for desired speed control. Otherwise program this parameter to "Not Installed".
"Coolant Level Sensor"
Program the "Coolant Level Sensor" to "Installed" if a coolant level sensor is installed on the engine. Otherwise program this parameter to "Not Installed".
"Auxiliary Pressure Sensor High Warning Point"
Program the "Auxiliary Pressure Sensor High Warning Point" to provide a warning to the operator if the auxiliary pressure exceeds the set point.
"Auxiliary Temperature Sensor High Warning Point"
Program the "Auxiliary Temperature Sensor High Warning Point" to provide a warning to the operator if the auxiliary temperature exceeds the set point.

Note: Compare the FLS and the FTS from the ECM with the values that are listed on the engine information plate. Only change the FLS and the FTS because of a mechanical change in the engine. The use of the wrong parameters will cause damage to the engine. The use of the wrong parameters may also void the Caterpillar warranty.
