Matched with the torque converter and power shift transmission, they provide years of dependable and efficient service. 4 Power Train ­ Transmission Electronic controls switch from converter drive to direct drive based on gear selection, maximizing efficiency and power application. Tractor and scraper engines are synchronized for smooth operation and longer service life. [. . . ] The ADEM A4 controller automatically compensates for low alternator output at low idle by raising the rpm for brief intervals to keep the batteries fully charged. Combined monitoring systems, easy access diagnostics and more durable components make routine maintenance and servicing simple and fast. The Electronic Monitoring System (EMS III) is designed to monitor both the tractor and scraper from one location instead of two. Both the tractor and powered scraper use the same controller for parts commonality and easier servicing. A variety of diagnostic codes are accessible through the EMS main display module, via the Electronic Technician (Cat ET). This offers a head start on problem solving, so with a radio call the service technician can know which tools, troubleshooting guides, and possibly even replacement parts to bring to the machine. The EUI system has fewer moving parts than mechanical unit injection and requires few adjustments. The ADEM A4 controller communicates with the monitoring system (EMS) to warn the operator when problems arise, to help avoid major damage. EUI engines have virtually no mechanically controlled parts to wear or adjust. These have been replaced by electronic controls, reducing maintenance costs and increasing machine availability. Product Link is a wireless system that allows the customer to track machine data such as location, service meter hours as well as machine health information. The system can automatically issue alerts when the machine is operated beyond ownerdefined time and location limits. Product Link is available as a factory attachment or it may be installed in the field in that there is a mounting location for the module as well as an antenna on the machine. A wiring breakout is standard, eliminating the need to splice into existing wires. Electronic controls optimize the timing setting for varying conditions. The ADEM A4 controller matches timing to the load on the engine, engine rpm and temperature. The ADEM A4 controller monitors electronic sensors to determine the optimum fuel/air ratio. Fuel is precisely controlled during cranking, starting and acceleration to reduce smoke. The Engine Electronics are faster and more efficient than mechanically controlling the governor rack position. Simplified System. The electrical system has been redesigned to utilize three electronic control modules (ECM) on the tractor instead of four. The rearpowered scraper now has two ECMs rather than three. The ADEM A4 controller monitors air filter restriction.
