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 by the main spool (2). Pressure reducing valves (9) control the position of the main spool (2). The level of electric 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 consequently 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 from 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).

Designation of M4-12 valves; type code

Complete control blocks are to be defined in accordance with the type code. The ordering text is used to collate the technical features and requirements. The Bosch Rexroth Sales Organization derives a short code as well as a material number on the basis of the ordering text. Preferred variants were defined by the Bosch Rexroth organization for the assembly of M4-12 valves worldwide. Certain versions are not provided for assembly outside the central production location Augsfeld. Please see data sheet RA 64 278 for the designation of all component codes. Supplement the designation by your unit/factory number according to ZN 01215.

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. 4 Main spool actuated 2 5 3 1 X Y LSP P Main spool in central position T A B T

The hand lever is connected directly with the main spool and follows through the spool movement in case of electrohydraulic operation. 2) Non-following hand lever: 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 detented. Thus, it does not follow the movement of the spool in case of electrohydraulic operation.

On-board electronics: Electronic pilot module (EPM2)

Function The electronic pilot module controls the flow at the control block M4-12 by means of 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, it is 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 of type Bosch Kompakt 1. It is also possible to connect further CAN bus stations at the output to the last pilot module (see also RE 64815-B). Features Time functions (ramp functions), the form and gradient of characteristic curves can be parameterized and changed directly during the operating cycle via the CAN bus. Various diagnosis functions allow to monitor the fault-free operation of the pilot module. The following elements are monitored in the basic version: ­ Correct reception of a valid command value signal ­ Stability of the connection with the command value encoder ­ Adherence to the defined limits of supply voltage ­ Function of the pilot valves (short circuit, cable break) Malfunctions are indicated in the form of an error code (flashing 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 status telegram of the pilot module and can then be analyzed by the control. ­ Reduced cabling effort with CAN wiring through daisy chain ­ Controlled output stages with superimposed dither ­ Processor-independent watchdog Electronic pilot module EMP2 ­ Time ramps can be selected separately for valve outputs A and B, Open and Close (only for CAN, fixed parameter for analog module) ­ Modifiable characteristic curve from linear to progressive form separately for A and B (only CAN, fixed parameter for analog module) ­ Linear reduction of the curve, modifiable in operation, and therefore also linear reduction of the total flow (CAN only, fixed parameter for analog module) ­ Selectable time ramps for shutdown in case of error (only for analog module) ­ Selectable monitoring limits for operating voltage parameterizable via CAN bus ­ Protection type according to EN 60529 IP 69K (only with connected Bosch Kompakt plug-in connectors) ­ Condition monitoring · Internal saving of temperatures · Internal measurement of the operating hours · Internal saving of diagnostic data ­ Comprehensive options for customized parameterization by Rexroth in the factory
