Examples of electrical faults that can cause the red lamp to illuminate are (but not limited to): - --Failure of the internal microprocessor of the module - --High/Low voltage signal from the throttle POT inside the tractor cab - --Loss of engine speed signal into the module 1 Figure2-124 2-92 SECTION 2 -OPERATION The module will illuminate the appropriate engine warning light (yellow or red) based on the source of the fault, and will take additional action by adjusting the performance of the engine by one of following methods: - --Illuminate engine warning light only, no performance modification - --Illuminate engine warning light, perform speed derate only - --Illuminate engine warning light, perform power derate only - --Illuminate engine warning light, perform speed and power derate The appropriate engine warning light will remain illuminated and the performance derate will remain in effect until the system fault is corrected. The Operator cannot cancel or interrupt the derate sequence from occurring on the engine. The module does not recognize activation of nor is it tied into the EICS acknowledge/reset button on the dash of the tractor. If the tractor is shut down and then restarted, and the electrical fault still exists on the tractor (non- --critical or critical), the module will repeat the warning light and derate sequence. If the tractor is restarted and the fault has been corrected, the tractor will return to normal operation. If the tractor is not shut down, and the alarm condition is corrected, the tractor will return to normal operation without having to shut it off and restart it. Important: Whenever an engine warning light (yellow or red) is illuminated on the EICS of the tractor shut the tractor down and contact your Buhler Versatile Dealer to investigate the cause of the concern. Your Buhler Versatile Dealer will coordinate the repair of the engine via an authorized Cummins Engine Company dealer/distributor. 2-93 SECTION 2 -OPERATION ADDITIONAL FEATURES OF THE ELECTRONIC INSTRUMENT CONTROL SYSTEM Automatic Shutdown Conversion -Each tractor is manufactured so that the operator can convert the Electronic Instrument Control System to shut the tractor engine off. Tractors are assembled with the engine shutdown feature disabled. The operator has the option of enabling the feature at any time. If the operator desires to enable the automatic shutdown feature, proceed as follows: 1. Unhook the battery cables from the batteries. This will prevent any possibility of an accidental short while making the conversion. See Section 3 for information on how to disconnect the cables. NOTE: Disconnecting the batteries will not remove any calibration numbers from the memory of the Electronic Instrument Control System. If the tractor is equipped with an optional Tractor Performance Monitor (TPM), the TPM may have to be reset. 2. Remove the cover, 1, from the electrical control panel located directly behind the operator’s seat. 1 Figure 2-125 2-94 SECTION 2 -OPERATION 3. Locate the small pin connector, 1, for the shutdown circuit. The pin connector is between the 3-amp turn signal fuse and the 10-amp tail lamp fuse. Remove the 3-amp fuse and 10-amp fuse from their locations to give better access to the small pin connector. 1 Figure 2-126 4. Using a small pair of needle-nose pliers, pull straight upward on the small pin connector, 1, and reinstall it so the front two pins are connected together. The rear pin will now be bare. Reinstall the 3-amp and 10-amp fuses. 1 Figure 2-127 5. Locate the shutdown relay position, 1, ( the fourth relay from the right), and install a relay (part #9706720 purchased from your Buhler Versatile dealership). Press the relay firmly into the electrical control panel. 6. Reinstall the cover onto the electrical control panel. 7. Reconnect the battery cables. To disable the shutdown feature, follow this procedure in reverse order. 1 Figure 2-128 2-95 SECTION 2 -OPERATION External Shutdown Conversion -Each tractor is manufactured so that the operator can convert the Electronic Instrument Control System to shut the tractor engine off via a signal from an outside source (i.e., a towed implement that is powered by a separate engine). If the tractor Electronic Instrument Control System receives a signal from an external source, the Electronic Instrument Control System will react in the same manner as detailed in “Low Engine Oil Pressure ” or “High Engine Coolant Temperature” If the external shutdown conversion is made on the tractor and a shutdown situation is present, the electronic monitor will not inform the operator whether it is a tractor function or an external signal causing the shutdown. The operator must look at the warning lights and gauges on the dash to determine the cause. NOTE: Only low engine oil pressure or high engine coolant temperature will cause a tractor related automatic shutdown. Tractors are assembled with the external engine shutdown feature disabled. The operator has...
