In this case the proportional valve can be used as follows: S, S with the internal feedback from the spool position sensor. Models with integrated electronic unit OE he model comprises an electronic control box that is mounted together with the position sensor on either of the solenoids. he connection of the position sensor to the control box is provided by a cable. For models with two solenoids, the solenoid mounted opposite the control box is connected to the control box by a EN 7-8 connector. he connection of the supply voltage, control signal, program input and external output of the position sensor is implemented in a -pin connector (ELK ). he connection of the external feedback is provided by a -pin connector, which also has three supply voltages +, + and - for an external sensor available. he solenoid coils, including the control box, can be turned in the range of ± 9. he digital control unit enables the proportional valve to be controlled on the basis of data required from two feedback circuits. In this case the proportional valve can be used as follows: E roportional directional valve E*S Only with the internal feedback from the spool position sensor. E Only with the external feedback (pressure sensor, position sensor, etc.). E*S With internal and external feedback. he digital control unit utilizes pulse-with-modulation (WM) and supplies the solenoids with current proportional to the control signal. he supply current is additionally modulated with a dither frequency. Individual functional parameters are adjusted through software by a special programmer, or by computer through the RS interface. he cable kit must be ordered separately, as detailed on page. he correct function of the digital control unit is signaled by a green LED. he incorrect function (failure) is indicated by a red LED. s a standard, the proportional valve is delivered with factory setting.
