5 E 92750/ V osch exroth 5/44 Technical Data Hydraulic fluid efore starting project planning, please refer to our data sheets E (mineral oil), E (environmentally acceptable hydraulic fluids) and E (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The variable pump 10V is unsuitable for operation with HF, HF and HFC. If HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in E and E must be observed. When ordering, please indicate the used hydraulic fluid. Operating viscosity range For optimum efficiency and service life, select an operating viscosity (at operating temperature) within the optimum range of ν opt = opt. operating viscosity mm 2 /s depending on the circuit temperature (closed circuit). Limits of viscosity range The limiting values for viscosity are as follows: ν min = 5 mm 2 /s short term (t < 3 min) at max. perm. temperature of t max = +115 C. ν max = 1600 mm 2 /s short term (t < 3 min) at cold start (p 30 bar, n 1000 rpm, t min = -40 C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes. Note that the maximum hydraulic fluid temperature of 115 C must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 5 K higher than the average case drain temperature. pecial measures are necessary in the temperature range from -40 C to -25 C (cold start phase), please contact us. For detailed information about use at low temperatures, see E election diagram Viscosity ν in mm 2 /s V 22 V 32 V 46 V 68 V Temperature t in C t min = -40 C Hydraulic fluid temperature range t max = +115 C ν opt. Details regarding the choice of hydraulic fluid The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (ν opt ) - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: t an ambient temperature of X C an operating temperature of 60 C is set. In the optimum operating viscosity range (ν opt ; shaded area) this corresponds to the viscosity classes V 46 or V 68; to be selected: V 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. t no point in the system may the temperature be higher than 115 C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.

6 6/44 osch exroth 10V E 92750/06.09 Technical Data Filtration The finer the filtration, the higher the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit. To ensure functional reliability of the axial piston unit the hydraulic fluid must have a cleanliness level of at least 20/18/15 according to IO Depending on the system and the application, for the 10V, we recommend Filter elements β With a rising differential pressure at the filter elements, the β-value must not deteriorate. t very high hydraulic fluid temperatures (90 C to max. 115 C) at least cleanliness level 19/17/14 according to IO 4406 is required. If the above classes cannot be observed, please contact us. For notes on filtration types, see page 38.

10 10/44 osch exroth 10V E 92750/06.09 Pressure Cut-Off, D The pressure cut-off corresponds to a pressure regulation which, after reaching the set pressure, adjusts the displacement of the pump to V g min. This valve prevents the operation of the high-pressure relief valves when accelerating or decelerating. oth the pressure peaks occurring when the swashplate is swiveled rapidly and also the maximum pressure in the system are safeguarded by the high-pressure relief valves. The setting range of the pressure cut-off may be anywhere within the entire operating pressure range. However, it must be set 30 bar lower than the setting of the high-pressure relief valves (see setting diagram, page 9). Please state the setting value of the pressure cut-off in plain text when ordering.

14 14/44 osch exroth 10V E 92750/06.09 D - Hydraulic Control, peed elated The D control is an engine speed-dependent, or automotive, type control system. The built-in D regulating cartridge generates a pilot pressure that is proportional to pump (engine) drive speed. This pilot pressure is directed to the positioning cylinder of the pump by a solenoid actuated 4/3 way directional valve. Pump displacement is infinitely variable in each direction of flow, and is influenced by both pump drive speed and discharge pressure. Flow direction (i.e. machine forward or reverse) is controlled by energizing solenoid a or b. Increasing pump drive speed generates a higher pilot pressure from the D cartridge, with a subsequent increase in pump flow and/or pressure. Dependent on the selected pump operating characteristics, increasing system pressure (i.e. machine load) causes the pump to swivel back towards a smaller displacement. Engine overload (anti-stall) protection is achieved by the combination of this pressure-related pump de-stroking, and the reduction of pilot pressure as the engine speed drops. ny additional power requirement, such as implement hydraulics, may result in further engine pull down. This causes a further reduction in pilot pressure and therefore pump displacement. utomatic power division and full utilization of available power is thus achived for both the vehicle transmission and the implement hydraulics, with priority given to the implement hydraulics. To provide controllable reduced vehicle speed operation when high engine speeds are required for fast implement hydraulics, various inching options are available. The D regulating cartridge can also be used in pumps with conventional control devices, such as EP, HW or HD, to provide an engine anti-stall function, or as a combination of automotive and displacement control functions. pplication of the D control is only appropriate on certain types of vehicle drive systems, and requires a review of the engine and vehicle parameters to ensure proper application of the pump, and safe and efficient machine operation. ll D applications must therefore be reviewed by a exroth pplication Engineer. ssignment Direction of rotation - Control - Direction of through put flow Direction of rotation ccw cw ctuation of solenoid Control pressure Through put flow Operating pressure a X 2 to M b X 1 to M a X 2 to M b X 1 to M Counterclockwise Clockwise witching solenoid a X 1 ; X 2 M ;M witching solenoid b Hydraulic control, speed related, D control valve, fixed setting, D1D2/D2D2 b a P M M F e M olenoid technical data D1 D2 Voltage 12 V DC (±20 %) 24 V DC (±20 %) Neutral position V g 0 de-energized de-energized Position V g max current energized current energized T 1 T 2 X 1 X 2 M Nominal resistance (at 20 C) 5.5 Ω 21.7 Ω Nominal power 26.2 W 26.5 W Current required, minimum effective ctuated time 100 % 100 % Type of protection see range of connectors on page 39 tandard: switching solenoid without manual emergency operation.
