Function

Control block M4-15 The directional valves are proportional valves according to the load-sensing principle. Actuator control The 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 reducing 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 pressure compensator (3). Load pressure compensation Pressure changes at the actuators or at the pump are compensated by the pressure compensator (3). The flow to the actuator remains constant even if the load varies. Flow limitation The maximum flow can be set mechanically and individually via stroke limiter (6). Pressure relief function The LS pressure as per actuator port can be adjusted internally 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).

Directional valve elements: Pressure compensator

Flow control due to individual pressure compensator Flow in l/min Pressure differential in bar Main spool actuated Main spool in central position

In the central position of the main spool there is no connection 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 position. The flow is kept constant even in case of parallel operation of actuators with different load pressures. The pressure compensator "S" boasts a load-holding function. This function is not leak-free. In its standard version it is equipped with one ring (5). The number of the rings inserted depends on the required flow.

On-board electronics: Electronic pilot module (EMP2)

Function The 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 connected individually to the control electronics of the machine. In case of CAN bus operation, is it possible to loop the electrical 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 output of the last pilot module (see also RE 64815-B). Features Time 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 (blinking 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 operation, 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 Options ­ Position 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.
