Power Train ­ Engine The C18 and the C15 engines with ACERTTM Technology works at the point of combustion to optimize engine performance. Matched with the torque converter and power shift transmission, it provides 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 neutral lock thumb control must be pressed to move the shifter from neutral. To use the top gear button, the operator must hold the yellow button until the gear display indicates the desired top gear. Releasing the yellow button sets the top gear. Joystick Control: positions, switches and buttons Grab Handle/Hand Rest. The grab handle/hand rest located next to joystick controller helps operators when adjusting seat swivel, and gives them a place to rest their hand while on the haul and return roads. Simple and easy to operate, the joystick enhances the productivity of operators of all skill levels. Requires less force to control the critical scraper functions and requires less lever travel. 1) Bowl (forward & back) 2) Ejector (side to side) 3) Apron (thumb rocker switch) 4) Transmission Hold 5) Cushion Hitch 6) Rocker switch (not shown ­ is on front of joystick) · · Auger (on/off) Push-Pull (bail up/down) * Standard open bowl does not have a rocker switch. 9 Electronic Controls Integrated electronic controls provide smooth, consistent shifts through the synchronization of engine and transmission speeds. Low Battery Elevated Idle. 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 Cat® 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 MEUI 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 should problems arise, to help avoid major damage. MEUI engines have significantly fewer 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. [. . . ] Cat dealers offer a variety of product support agreements, and work with customers to develop a plan that best meets specific needs. These plans can cover the entire machine, including attachments, to help protect the customer's investment. Your Cat dealer has videotapes, literature and other ideas to help you increase productivity, and Caterpillar offers certified operator training classes to help maximize the return on your machine investment.
