Electrical shock hazard. The electronic unit injector system uses 90-120 volts.
The ECM sends a high voltage signal to the unit injectors. To help prevent personal injury, do not disconnect the unit injector connector while the engine is operating. Do not come in contact with the harness connector for the unit injector while the engine is operating.
Tampering with the electronic system installation or the OEM wiring installation can be dangerous and could result in personal injury or death and/or engine damage.
Note: The control panel can only be programmed with electronic service tools and passwords. For information on programming, see the Service Manual, SENR6477, "Electronic Troubleshooting" module.The engine has a monitoring system that can respond to abnormal engine operation with these modes: , DERATE and SHUTDOWN. These modes are available in order to help prevent damage to the engine. The customer can program these modes "ON" or "OFF".A warning indicates a serious condition that requires immediate attention. If a derating occurs, the engine power and/or the engine rpm is limited.The following conditions will cause an engine shutdown:
Engine overspeed
High aftercooler coolant temperature
High coolant temperature (jacket water)
High crankcase pressure
Low engine oil pressureExcept for an overspeed shutdown, the monitoring system can be overridden. An override switch is located in the control panel. Use of the switch will allow the engine to provide full power during an abnormal engine operating condition. The override switch is provided only for use in emergency situations.For more information on the conditions that can initiate warnings, deratings, and shutdowns, see this Operation and Maintenance Manual, "Control Panel" topic (Operation Section).
