This control is used for 2-point control systems or as a base unit for controls with proportional valves (in addition an electric feedback device is required). The mechanical swivel angle limiting stop screws can be adjusted on both sides of centre within the range of Vg max down to 50 % Vg max , with the size 500 (HM2) from Vg max to 70% Vg max. Spring centering of the control cylinder is standard. It is used for settings and adjustments in the unpressurized zero (centre) position, however without a defined reset during high pressure operation. 2 versions are available: HM1 min. control pressure 290 psi (20 bar) for sizes 40, 71, 125 and 250 HM2 min. control pressure 725/1450/1812 psi (50/100/125 bar) for sizes 40...1000 see page 4 Please note: The Vgmin-stop for the variable displacement pump (A)A4VSO for open circuits is to be adjusted, so that with blocked pressure port B a minimum pressure of appox.. 20 bar is reached. HM1 For pump AA4CSG with HM1 control, the necessary control pressure can be taken out of the boost circuit (Port M E3). Recommended setting of the boost pressure relief valve: 362 psi (25 bar). The control pressure relief valve is not needed, and is replaced by a plug.

In conjunction with the compatible amplifier VT-SR7-1X we have a very accurate control of pump displacement is accomplished. This amplifier VT-SR7-1X is not included in the scope of supply for the HS-control. Please order separately acc. to RA 29993. Spring centering in the control cylinder is standard. It is used for settings and adjustments in the unpressurized zero position, however without a defined reset during high pressure operation. Mechanical swivel angle limiting stops on both sides of centre between Vg standard. max and 50 % Vg max (with size 500 to 70 % Vg max) are In order to minimize the control fluid consumption the control chambers in the sizes 125...1000 are sealed and can be bled through the ports R2 - R7 . In order to protect the servo valve the pump is supplied with a sandwich flushing plate (see schematic) . After the flushing process the flushing plate must be removed and the servo valve must be screwed directly onto the subplate (using the screws supplied). Please observe the commissioning and flushing instructions in RA 07700 and RE 29583.

Optional: HS4P with pressure transducer for additional pressure and power control HS4E without proportional valve HS4K, HS4KP with short circuit valve HS4M for operation under oil level Stop screws to limit the swivel angle between Vg dard. max and 50 % Vg max (for size 500 to 70 % Vg max) for both side of centre are stan- Spring centering in the control cylinder is standard. It is used for settings and adjustments in the unpressurized zero position, however without a defined reset during high pressure operation. In order to minimize the control fluid consumption the control chambers in pump sizes 125...1000 are sealed and can be bled via ports R2 - R7 . (A)A4VSO – open circuit When the valve is de-energized and the control pressure is on the pump swivels towards Vg min. The Vg min-stop set so that, when port B is plugged, a pressure of approx. 290 psi (20 bar) is reached. A4VSH, (A)A4VSG, (A)A4CSG – closed and semi closed circuit For controls of these pumps without short circuit valve it must be noted, that, when the valve is de-energized and the control pressure is on the pump will stroke towards Vg max (swivel angle range to the right). On pumps A4CSG with HS4-control the control pressure relief valve is not needed and replaced by a plug. 12/32 Bosch Rexroth Corporation HM, HS, HS4 and EO | RA 92 076/06.05 Technical data HS4(P) Size Control press. in P pmin psi (bar) pmax1) psi (bar) 40 71 125 180 250 355 500 750 1000 1450 (100) 1450 (100) 1450 (100) 1812 (125) 1812 (125) 1812 (125) 2175 (150) 2175 (150) 2175 (150) 4570 (315) Control stroke smax in (mm) 0.56 (14,2) 0.67 (17,1) 0.81 (20,7) 0.81 (20,7) 1.02 (25,9) 1.02 (25,9) 1.28 (32,6) 1.46 (37,0) 1.63 (41,4) Control area A in2 (cm2) 1.26 (8,1) 1.95 (12,6) 2.81 (18,1) 2.81 (18,1) 4.39 (28,3) 4.39 (28,3) 5.92 (38,2) 8.80 (56,8) 9.85 (63,6) Control volume VS max in3 (cm3) 0.70 (11,4) 1.31 (21,5) 2.29 (37,5) 2.29 (37,5) 4.47 (73,2) 4.47 (73,2 7.60 12.81 (124,5) (210) 16.06 (263,3) Control time tmin2) s 0,04 0,06 0,09 0,09 0,12 0,12 0,15 0,2 * Weight approx.

Manufacturers information concerning the maximum permitted tightening torques of the various fittings is to be observed! For DIN 13/ISO 68 mounting bolts, we recommend that tightening torques be checked on a case by case basis in accordance with VDI 2230, published 2003. – During and shortly after operation of a pump the housing and especially a solenoid can be extremely hot, avoid being burned!
