Of course, other system parameters may override this choice. Selecting The Best System For Your Needs The system drivers shown on the "Y" axis generally provide an initial indication of the basic type of fan drive system to pursue: INSTRUCTIONS: 1. Choose your most important drivers (cost, noise, temperature control or efficiency) for determining the appropriate fan drive system. You may choose any number of these drivers. 2. Assign a number between 1 and 10 for importance to the drivers you have chosen (10 being the highest importance). 3. Place these numbers in the boxes to the left of the drivers. 4. Multiply the importance number by the number in each circuit column. (ex. check valve circuit: 5, 1, 1, 1, etc.) Then put that product into the box to the right. 5. Total the numbers in the boxes for each circuit column. The highest total represents the system that will most likely fit your needs. Matrix of criteria vs. type of hydraulic fan drive systems.

14 Quick Reference Chart Concentric offers one of the widest selections of gear pumps and hydraulic motors in the industry. All Concentric products are designed to provide solutions to our customers' application challenges. Concentric pumps and motors are used for fan drive systems on skid steer loaders, wheel loaders, excavators, paving equipment, buses and forklifts. Leading equipment manufacturers throughout the mobile equipment market specify these components. The Concentric line of hydraulic pumps and motors covers a displacement range from .065 in.3 to 9.82 in.3. The various series include cast iron fixed clearance, aluminum body pressure balanced and cast iron pressure balanced designs. Both unidirectional and birotational configurations are available. Each series offers a large selection of shaft, flange and valve options to meet your application requirements. Concentric Pump & Fluid Motors for Fan Drive Systems Special fixed displacement product. Sizing characteristics differ from those shown in this catalog. Contact factory for assistance. * NOTE: As can be seen from the above quick reference chart, a displacement selection may cross several different pump or motor families (frame sizes). Frame sizes overlap intentionally. This provides capability in one frame size that is not achievable in another. For instance, the example illustrates that the displacement selected (27cc) is available in the WM900 and WM1500 motor. The WM1500 has higher bearing side load capability and pressure capability, but is not as economical as the WM900 model. If the application does not need these additional capacities in pressure and load, the WM900 would be the motor of choice; i.e. best value.

16 Concentric offers a complete line of Fan Drive electronic controls that interface directly with the electrohydraulic Fan Drive packages. These range in complexity from simple proportional plug and play controls that plug directly into the electrohydraulic valve coil, to stand alone electronic control packages that operate the entire fan drive control system. The controls illustrated demonstrate the spectrum of features available to the OEM. Concentric will assist the OEM in the control specification to achieve the optimum system for the specific vehicle. GENERAL OPERATION OF THE Concentric FAN DRIVE CONTROLLERS Fan drive controllers are designed to control the pressure relieving electro-proportional cartridge valves as part of a proportional fan-drive system. Since fan torque is a cubic function relative to speed, it is more economical to control fan speed using pressure control than flow control. These controllers range in sophistication from simple on-off inputs to multiple sensor proportional inputs and are designed to fit the needs of rugged offhighway vehicles. The controllers illustrated operate on the principle that temperature is to be proportionally controlled between design set points. They provide the necessary output to the electrohydraulic proportional valve in the fan drive system allowing precise fan motor speed correlated to temperature. The inputs can range from a temperature switch providing a voltage input to the controller, to an analog sensor input correlated to temperature. The controllers illustrated in this catalog are typical of the two types developed specifically for fan drive systems. However, special controllers can be developed for higher volume OEM applications. INTEGRAL PLUG-IN CONTROLLERS DESCRIPTION These controllers are designed for single input temperature control. They consist of a series of convenient, plug-mounted control amplifiers for controlling the fan drive proportional valves. These valve solenoids and controllers have DIN 43650/ISO 4400 electrical connectors. These controllers come in a variety of input and output configurations and adjustments. OPERATION This control module utilizes high frequency switching (PWM) to supply a proportional valve solenoid with an input signal that is proportional to an external signal. The external signal can be from a 10K potentiometer, 0–5 VDC, 0-10 VDC, 0–20 mA, or from other pre-set levels. NOTE: Simplified controllers are also available (re: ramping only) NOTE: These controllers fail to full fan speed mode. TYPICAL FEATURES • Mounts directly to solenoid coils with DIN 43650A connectors. • IP65 internal protection (IEC529). • Adjustments accessible with a removable cover. • No internal fuses; circuit limits current electronically. • Short circuit proof and reverse polarity protected. • Connector can be disconnected from coil when powered. • Maximum current adjustment does not affect minimum current setting. • Independent ramp adjustments and internal supply for potentiometer. • Fails to full fan speed.

17 TYPICAL RATINGS Supply Voltage: 9–32 VDC Control Input Signal Options: 10 K external potentiometer (accepts 5K to 50K pots), or 0–5 VDC signal, 0-10 VDC signal, or 0–20 mA current signal. Input Resistance: Voltage Control: 125K Ohms; Current Control: 50K Ohms Ramp Up and/or Down: 0.01–5.0 seconds (independently adjustable) Operating Conditions: –20° to 85°C (-4º to 185ºF); 0 to 85% relative humidity REMOTE MOUNTED CONTROLLER (See Page 20 for illustration) Description: These controllers are designed for multiple input temperature control. Power supply input is 12 or 24 VDC (nominal). The controller accepts up to three analog temperature sensor inputs and up to two digital inputs. The OEM can select the number of temperature inputs by setting a DIP switch on the controller. NOTE: Once specified, these can be factory preset by Concentric. The temperature range accepted by the controller is set by the sensor specifications. See Page 19 for sensor input requirements. The controller compares the actual value of the temperature inputs with programmed setpoints (specified by the OEM) to generate a proportional current output to the valve. The valve proportionally controls the pressure at the fan motor and therefore mo-tor speed. Proportional control occurs when the temperature sensor inputs fall within the minimum and maxi-mum temperature setpoints of the controller. Turning on the digital input causes the controller to ramp for a 2.5 second period from maximum current output (idle fan speed) to the necessary current output required to achieve set point fan speed. The fan cools by operating between a starting fan speed and a maximum fan speed, which are determined by the cooling system layout. These requirements should be specified on Page 19 (sensor inputs). Calibrating the controller potentiometer and tuning the pressure setting of the valve sets both speeds. Digital inputs can also be set to actuate full fan speed mode when required for engine retarding or other applications where high heat loads are generated. Idling speed is the mode of operation of the fan when it is not required to cool. The controller and proportional valve are designed to provide a maximum fan speed in the cooling circuit in case of a power loss. Overcurrent protection is provided. Once an overcurrent situation is detected, the controller output turns off for several cycles of 10 msec. until the situation corrects itself. If the overcurrent situation continues, the controller will eventually shut off completely to allow the fan to run at maximum speed and cool the system. The fan controller has two modes of operation; calibration and run. A DIP switch sets the mode of operation. In calibration mode, the OEM powers the controller and adjusts the calibration potentiometer until the fan is running at the desired rpm corresponding to the minimum temperature setpoint programmed in the controller (the starting speed). This is the speed to which the fan should ramp when any of the input temperatures go above the minimum temperature setpoint or the digital input turns on. Once the unit is calibrated, the OEM selects run mode. In run mode, changing the setting of the potentiometer will have no effect on the output. NOTE: Once specified, these can be factory preset by Concentric. The controller is packaged for the rugged mobile environment. OEM specific packaging and connection styles are available.

An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level.
