Complete Fan Drive Systems The Electro-hydraulic (EH) Fan Drive System cools your engine and vehicle sub-systems by controlling a hydraulic pump and motor with a digitally programmable controller. The EH Fan Drive System equipped with the Two Channel Amplifier offers fast, quiet and efficient cooling for engine coolant, hydraulic fluid, charge air and entire engine compartment. Table of Contents Electro-hydraulic Fan Drive benefits include: • Flexible installation for optimum fan location • Elimination of belt maintenance • More accurate control of charge air temperature can help reduce engine emissions • Improvement in fuel economy • Increased power output • Choice of variable- or fixed- displacement systems Eaton can be your single source for fan drive systems. Eaton Fan Drive Systems can include: • Pump (fixed- or variable- displacement) • Motor • Valves & manifold • Electronic controls • Compact patented reservoir • Filter • Hoses and fittings A fully integrated electronically controlled Eaton Hydraulic Fan Drive System delivers a comprehensive cooling solution with complete controllability.

Applications and Benefits Applications: On-highway vehicles • Buses • Recreational vehicles Construction machinery • Excavators • Loaders • Cranes • Forklifts Agriculture machinery • Tractors • Forest machinery Benefits of Electronic Control • Functions with Engine Control Module Input or Vehicle Sensor and Switch Inputs: – Allows a wide variety of configurations. • Communications via RS 323 or CANbus link: – Provides versatility in communications. • Conditions engine control module signal: – Filters noise, inverts signal, and re-scales signal to optimize control. • Uses closed-loop current control, instead of voltage control: – Improves control accuracy of fan speed by eliminating temperature effects on proportional valve coil. application SpEcific BEnEfitS Buses • Modulates fan speed – Reduces operating power and noise. • Limits fan speed on start-up – Reduces fan power draw on start-up. • Increased fuel economy – Reduced fan power requirements lead to better fuel economy. Recreational Vehicles • Ramps between fan speed settings – Ensures gentle speed transitions and provides smooth operation. • Reduces operation noise – Electronic control reduces the noise of the fan and pump, providing better passenger comfort. Wheel Loaders • Encapsulated construction – Allows installation in more exposed locations on the vehicle. • Flexible installation – The electronic control of the Fan Drive System al lows flexible installations for optimum fan location. • Fan reverse feature – Reverse fan operation facilitates removal of debris from the vehicle radiator.

EFX Electronic Controller Eaton EFX electronic controllers and I/O modules provide a full range of electronic controls. With an array of controller options and I/O modules, an EFX system can address any application need. All EFX products are IP67 rated and are built for harsh mobile and industrial application environments. The EFX line is programmed and configured using Eaton CONTROL F(x)™ software. EF(x) Controllers It is prepared for CANbus communications on a ve hicle network. Software for controlling the EH Fan Drive System is loaded in the controller memory at the factory. Control software parameters are adjusted via RS 232 hook up to a laptop computer. Applications...
