20 RENR5042-02 Troubleshooting Section System Configuration Parameters “Top Engine Limit” (TEL) i02290263 System Configuration Parameters SMCS Code: 1901 System configuration parameters are parameters that affect the emissions and the power of the engine. 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. Parameter Descriptions “Equipment g00763900 Illustration 6 “Equipment allows the customer to enter a description into the Electronic Control Module (ECM) in order to identify the machine. 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. is a customer programmable parameter that defines the maximum allowable engine speed for maximum power. can be programmed up to the maximum rated engine speed. is defined along the engine’s lug curve. “Engine Serial Number” “Engine Accel. Rate” 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. “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. Note: When you are requesting factory passwords, always use the engine serial number that is programmed in the ECM. “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. “Rating Number” “PTO Mode” 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.
The rating tiers are A through E. “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. Note: Factory passwords are required in order to change the “Rating Number”. “Set/Resume” When “PTO Mode” is programmed to “Set/Resume”, the ECM allows PTO operation with enhanced features.
