Technical Data Hydraulic fluid For detailed information on the choice of hydraulic fluids and application conditions, please see our catalog pages RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF-hydraulic fluids) prior to configuration. The variable displacement pump A11VO is unsuitable for operation with HFA, HFB and HFC. When using HF- or environmentally acceptable (Eco-evaluated) hydraulic fluids possible restrictions in the technical data may have to be taken in consideration. If required please consult with our technical support department. The hydraulic fluide type used should be stated on the order. Operating viscosity range We recommend you to choose the operating viscosity (at operating temperature) in the optimum range for efficiency and useful life of νopt = opt. operating viscosity 16...36 mm2/s

Explanation of selection of the hydraulic fluid Knowledge of the operating temperature in the tank (open circuit) depending on the ambient temperature is a prerequisite for the correct choice of hydraulic fluid. The hydraulic fluid should be selected so that the operating viscosity is in the optimum range (νopt) in the operating temperature range, see selection diagram, shaded area. We recommend you to choose the respective higher viscosity class. Example: At an ambient temperature of X° C an operating temperature of 60° C is set in the circuit. In the optimum operating viscosity range (νopt; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Note: The leakage oil temperature, influenced by pressure and speed, is always above the tank temperature. The temperature may not be higher than 115°C at any point in the machine. If the above conditions cannot be satisfied in the case of extreme operating parameters or high ambient temperatures, please ask.

related to the tank temperature (open circuit). Limit viscosity range The following values apply for borderline conditions:

Filtration

νmin = 5 mm2/s temporary (t < 3 min) at max. perm. temperature of tmax = +115°C.

The finer the filtration the better the cleanliness class of hydraulic fluid reached, the longer the life of the axial piston unit.

Note that the max. hydraulic fluid temperature of 115°C may not be exceeded even locally (e.g. in the bearing area).

To ensure functional reliability of the axial piston unit at least cleanliness class

νmax = 1600 mm2/s temporary (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 min-1, tmin = -40°C). Only for starting up without load. The optimum operating viscosity must be reached within about 15 minutes. Special measures are necessary in the temperature range from -40°C to -25°C, please ask. For detailed information about use at low temperatures, see RE 90300-03-B. 2500-40° 1600 1000 600 400

The housing flushing is unnecessary in versions with charge pump (A11VLO), since a part of the charge flow is directed to the housing. Higher case drain flow beyond volumetric rotary group losses and control flow may be noticed.

Pressure at port A or B

The charge pump is a circulating pump with which the A11VLO (size 130...260) is filled and therefore can be operated at higher speeds. This also simplifies cold starting at low temperatures and high viscosity of the hydraulic fluid. Tank charging is therefore unnecessary in most cases. A tank pressurization of a max. 2 bar is permissible with charge pump.

LR Power Control The power control regulates the displacement of the pump depending on the operating pressure so that a given drive power is not exceeded at constant drive speed.

pB • Vg = constant

Size 40-145: LR

pB = operating pressure

T1

Vg = displacement

Vg max

The precise control with a hyperbolic control characteristic, provides an optimum utilization of available power. The operating pressure acts on a rocker via a piston. An externally adjustable spring force counteracts this, it determines the power setting. If the operating pressure exceeds the set spring force, the control valve is actuated by the rocker, the pump swivels back (direction Vg min). The lever length at the rocker is shortened and the operating pressure can increase at the same rate as the displacement decreases without the drive powers being exceeded (pB • Vg = constant). The output power (characteristic) is influenced by the efficiency of the pump.

LR Power Control LRC Override with cross-sensing

LR3 High pressure related override

Cross sensing control is a summation power control system, whereby the total power, of both the A11VO and of a same size A11VO power controlled pump mounted onto the through drive, are kept constant.

The high pressure related power override is a total power control in which the power control setting is piloted by the load pressure of an attached fixed displacement pump (port Z).

If a pump is operating at pressures below the start of the control curve setting, then the surplus power not required, in a critical case up to 100%, becomes available to the other pump. Total power is thus divided between two systems as demand requires. Any power being limited by means of pressure cut-off or other override functions is not taken into account. Half side cross-sensing function

As a result the A11VO can be set to 100 % of the total drive power. The power setting of the A11VO is reduced proportional to the load-dependent rise in operating pressure of the fixed displacement pump. The fixed displacement pump has priority in the total power setting. The measuring area of the power reduction pilot piston is designed as a function of the size of the fixed displacement pump. Size 40-145: LR3

When using the LRC control on the 1st pump (A11VO) and a power-controlled pump without cross-sensing attached to the through drive, the power required for the 2nd pump is deducted from the setting of the 1st pump. The 2nd pump has priority in the total power setting.

T1

The size and start of control of the power control of the 2nd pump must be specified for rating the control of the 1st pump.

LR Power Control LG1/2 Pilot pressure related override This power control works by overriding the control setting with an external pilot pressure signal. This pilot pressure acts on the adjustment spring of the power regulator via port Z. The mechanically adjusted basic setting can be hydraulically adjusted by means of different pilot pressure settings, enabling different power mode settings. If the pilot pressure signal is then adjusted by means of a external power limiting control, the total hydraulic power consumption of all users can be adapted to the available drive power from the engine. The pilot pressure used for power control is generated by an external control element that is not a component part of the A11VO (e.g. see also data sheet RE 95310, Electronic Load Limiting Control, LLC). LG1 Negative power override

LG2 Positive power override

Power control with negative override, LG1: the force resulting from the pilot pressure is acting against the mechanical adjustment spring of the power control.

Power control with positive override, LG2: the force resulting from the pilot pressure is additive the mechanical adjustment spring of the power control.

Increasing the pilot pressure reduces the power setting.

An increase in pilot pressure increases the power output.

LR Power Control LE1/2 Electrical override (negative)

Contrary to hydraulic power control override, the basic power setting is reduced by an electrical pilot current applied to a proportional solenoid. The resulting force is acting against the mechanical power control adjustment spring.

T1

GM

A

Increase in current = decrease in power If the pilot current signal is adjusted by a load limiting control (e.g. LLC control RE 95310) the power consumption of all mechanical and hydraulic actuators is decreasing the A11VO power setting to match the remaining available power from the engine.

LR Power Control LRDS Power control with pressure cut-off and load sensing

Size 40-145: LRDS X

The load-sensing control is a flow control option that operates as a function of the load pressure to regulate the pump displacement to match the actuator flow requirement.

(1)

The flow depends here on the cross section of the external sensing orifice (1) fitted between the pump outlet and the actuator. The flow is independent of the load pressure below the power curve and the pressure cut-off setting and within the control range of the pump.

T1

The sensing orifice is usually a separately arranged load sensing directional valve (control block). The position of the directional valve piston determines the opening cross section of the sensing orifice and thus the flow of the pump. The load-sensing control compares pressure before and after the sensing orifice and maintains the pressure drop across the orifice - and therefore the pump flow - constant as a function of the orifice size. If the differential pressure ∆p increases, the pump is swivelled back towards Vg min and, if the ∆p decreases the pump is swivelling out towards Vg max until the pressure drop across the sensing orifice in the valve is restored.

This control option adds a proportional solenoid to override to the mechanically set load-sensing pressure. The pressure differential change is proportional to the solenoid current.

This control option adds an external proportional pilot pressure signal (to port Z) to override the mechanically set load-sensing pressure.

Increasing current = smaller ∆p-setting

LR Power Control LR... Power control with stroke limiter The stroke limiter can be used to vary or limit the displacement of the pump continuously over the whole control range. The displacement is set in LRH with the pilot pressure pSt (max. 40 bar) applied to port Y or in LRU by the control current applied to the proportional solenoid. A DC current of 12V (U1) or 24V (U2) is required to control the proportional solenoid. The power control overrides the stoke limiter control, i.e. below the hyperbolic power characteristic, the displacement is controlled, by the control current or pilot pressure. When exceeding the power characteristic with a set flow or load pressure, the power control overrides and reduces the displacement following the hyperbolic characteristic.

LRH1/5 Hydraulic stroke limiter (negative characteristic)

To permit operation of the pump displacement control from its starting position Vg max to Vg min, a minimum control pressure of 30 bar is required for the electrical stroke limiter LRU1/2 and the hydraulic stroke limiter. The required control oil is taken either from the load pressure, or from the externally applied control pressure at the G port. To ensure functioning of the stroke limiter at low operating pressure as well, the port G must be supplied with external control pressure of approx. 30 bar. Note: If no external control pressure is connected at G, the shuttle valve must be removed.

Installation and Commissioning Instructions General The pump housing must be filled with hydraulic fluid during commissioning and before operation (filling of housing case). Commissioning must take place at low speed and without load until the system has been bled completely. In long periods at standstill the housing can empty via the service lines, sufficient filling of the housing must be guaranteed when restarting. The case drain for the pump housing cavity must be drained into the tank through the highest leakage oil port. The minimum suction pressure at port S of 0.8 bar absolute (without charge pump) or 0.6 bar (with charge pump) may not be dropped below of. Installation below tank

Installation above tank

Pumps under minimum oil level in the tank (standard).

Pumps above minimum oil level in the tank.

– any installation position. – installation position "shaft upwards": Make sure that the pump housing is completely filled during commissioning. An air cushion in the area of the bearings causes damage to the axial piston unit. Measures: – Fill the axial piston pump via the highest leakage oil port T1, T2, R prior to commissioning. – Recommendation: fill suction lines.

The housing cavity may empty via the service lines during long periods of standstill (air gets in through the shaft seal), the bearing is not adequately lubricated when restarting. The axial piston unit must be filled via the highest leakage oil port prior to restarting (bleed via port R). Emptying via the leakage oil line can be prevented with a check valve in the leak oil line (opening pressure 0.5 bar). Emptying via the service ports can be reduced with a special version of the control plate. – installation position "shaft horizontal" and "shaft upwards". – installation position "shaft upwards".

– Operate the pump at low speed (starter speed) until the pump is completely filled. – Minimum immersion depth of the suction or leakage oil line in the tank: 200 mm (related to the min. oil level in the tank).

– The version A11VLO (with charge pump) is not designed for installation above the tank. See installation below tank for further measures. Additional measures for installation above the tank: – max. permissible suction height hmax = 800 mm – min. permissible pressure at port S (min. suction pressure) – For control options with pressure control, displacement limiters, HD and EP control, the minimum displacement setting must be Vg ≥ 5% • Vg max. – Recommendation: use suction line with "goose neck".
