Function
Load pressure compensationPressure changes at the actuators or at the pump are com-pensated by the pressure compensator (3). The flow to the actuator remains constant even if the load varies.Flow limitationThe maximum flow can be set mechanically and individually via stroke limiter (6).Pressure relief functionThe LS pressure as per actuator port can be adjusted inter-nally via the LS pressure relief valves (4) or externally via the LS ports MA, MB.Pressure relief/anti-cavitation valves (5) protect the actuator ports A and B against pressure peaks and against external forces.The highest load pressure is signaled to the pump via the LS line and the integrated shuttle valves (7).
Control block M4-15The directional valves are proportional valves according to the load-sensing principle.Actuator controlThe flow direction and level of flow reaching the actuator ports (A or B) is determined at the main spool (2).Pressure reducing valves (9) control the position of the main spool (2). The level of electrical current at the pressure reduc-ing valve determines the level of pilot pressure in the spring chambers (8) and therefore also the stroke of the main spool (P → A; P → B).The pressure difference at the main spool (2), and therefore the flow to the actuator, is maintained constant via the pres-sure compensator (3).

Notes on the dimensioning of control oil supply with servohydraulic operation
If servohydraulic operation is used in the control block, please note:External pilot oil supply:
p – st = 30 + 2 bar constantq – st = 2 l/min per servohydraulic spool axisRequired and mandatory for inlet element P –
Internal pilot oil supply:6 servohydraulically controlled spool axes maximum possible –No pilot oil supply for external actuators –Δ–– p at the inlet element needs to be 35 bar at leastNo internal pilot oil supply in the inlet element –

Directional valve elements: Pressure compensator
In the central position of the main spool there is no connec-tion between P and the actuator ports A and B. With this operational state the pressure compensator spool (1) is moved to the left by the pump pressure against the spring (2).When the main spool (3) is operated (= metering orifice), the LS pressure reaches the spring chamber (4) and moves the pressure compensator spool to the right into the control posi-tion. The flow is kept constant even in case of parallel opera-tion of actuators with different load pressures.The pressure compensator “S” boasts a load-holding func-tion. This function is not leak-free.In its standard version it is equipped with one ring (5). The num-ber of the rings inserted depends on the required flow.

Safety notes!Following hand lever – 1): Electrohydraulic operation can be overruled by mechanical operation. The hand lever is con-nected directly with the main spool and follows through the spool movement in case of electro-hydraulic operation.Non-following hand lever – 2): The hand lever is connected to the main spool by means of a coupling. When the main spool is in central position, the hand lever can be de-tented. Thus, it does not follow the movement of the spool in case of electrohydraulic operation.

On-board electronics: Electronic pilot module (EMP2)FunctionThe electronic pilot module controls the flow at the control block M4-15 via an analog or digital electrical signal.An analog (voltage or PWM signal) or digital (CAN bus) input signal is converted by the pilot module into a pilot pressure via two electrohydraulic pressure reducing valves.In case of an analog input signal, each pilot module is con-nected individually to the control electronics of the machine.In case of CAN bus operation, is it possible to loop the electri-cal connection to the next pilot module via a second plug-in connection (daisy chain cabling). The complete valve control block is then connected to the control of the machine via the 4-pin plug of the first pilot module.The electrical connection is realized via a 4-pin plug, type Bosch Kompakt 1.It is also possible to connect further CAN bus units at the out-put of the last pilot module (see also RE 64815-B).
FeaturesTime functions (ramp functions), form of the characteristic curve and increase are parameterizable and can be changed directly during the working cycle via the CAN bus.Various diagnosis functions allow to monitor the fault-free function of the pilot module.The following elements are monitored with the standard version:
Correct reception of a valid command value signal –Stability of the connection to the command value encoder –The adherence to the defined limits of supply voltage –Function of the pilot valves (short-circuit, cable break) –
Malfunctions are indicated in the form of a error code (blink-ing code) via an LED that can be seen from the outside.With the analog module, there is a relay output available as error indicator.With the CAN bus variant, the error code is transferred to the control in the state telegram of the pilot module and can then be analyzed by the control.
Low cabling effort with CAN wiring through daisy chain –Clocked output stages with superimposed dither –Processor-independent watchdog –Selectable time ramps, separated individually for valve –outputs A and B, Open and Close (only for CAN, fixed parameter for analog module)
Electronic pilot module EMP2
Modifiable characteristic curve from linear to progressive –trend separately for A and B (only CAN, fixed parameter for analog module)Linear decline of the characteristic curve, modifiable in op- –eration, and therefore also linear lowering of the complete flow (CAN only, fixed parameter for analog module)Selectable time ramps for shutoff in the error case (only for –analog module)Selectable monitoring limits for operating voltage –Parameterizable via CAN bus –Protection class according to EN 60529 IP 69K – (only with plugged Bosch Kompakt connectors)Condition Monitoring –
Internal saving of temperatures•Internal counting of the operating hours•Internal saving of diagnostic data•
Comprehensive parameterizibility according to the client's –requirements by Rexroth in the factory
OptionsPosition sensor –with measuring port –
Electronic pilot module: Parameter specifications
The form for the parameter specifications can be found in the project planning aid RE 64815-02. It serves for setting the electronic pilot module according to the requirements of the customer ex factory.
