SEBU7901-01 15 Safety Section Engine Electronics i01563743 Engine Electronics SMCS Code: 1000; 1400; 1900 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. This engine has a comprehensive, programmable Engine Monitoring System. The Engine Control Module (ECM) has the ability to monitor the engine operating conditions. If any of the engine parameters extend outside an allowable range, the ECM will initiate an immediate action. The following actions are available for engine monitoring control: WARNING, DERATE, and SHUTDOWN.
These engine monitoring modes have the ability to limit engine speed and/or the engine power. g00771487 Illustration 13 Many of the parameters that are monitored by the ECM can be programmed for the engine monitoring functions. The following parameters can be monitored as a part of the Engine Monitoring System: Typical example Alternate Grounding Stud To Battery Ground Operating Altitude Proper grounding for the engine electrical system is necessary for optimum engine performance and reliability. Improper grounding will result in uncontrolled electrical circuit paths and in unreliable electrical circuit paths.
Engine Coolant Level Engine Coolant Temperature Uncontrolled electrical circuit paths can result in damage to main bearings, to crankshaft bearing journal surfaces, and to aluminum components. Engine Oil Pressure Engine Speed Engines that are installed without engine-to-frame ground straps can be damaged by electrical discharge. Fuel Temperature Intake Manifold Air Temperature To ensure that the engine and the engine electrical systems function properly, an engine-to-frame ground strap with a direct path to the battery must be used. This path may be provided by way of a starting motor ground, a starting motor ground to the frame, or a direct engine ground to the frame.
System Voltage The Engine Monitoring package can vary for different engine models and different engine applications. However, the monitoring system and the engine monitoring control will be similar for all engines. All grounds should be tight and free of corrosion. The engine alternator must be grounded to the negative battery terminal with a wire that is adequate to handle the full charging current of the alternator. Note: Many of the engine control systems and display modules that are available for Caterpillar Engines will work in unison with the Engine Monitoring System. Together, the two controls will provide the engine monitoring function for the specific engine application.
