Control device for controlling magnetically operated hydraulic constant valve, has change over switch provided in control circuit for reading data memory or for alternatively controlling actuator by control signal

摘要

The device has a control circuit (100) for electrically controlling a magnetic actuator (3). A non-volatile data memory (130) is provided in the actuator and read by the control circuit via two-wire connections (2a, 2b). A change over switch (4) is provided in the control circuit for reading the data memory or for alternatively controlling the actuator by a control signal. A switch (11) is provided at the actuator and controlled by a control element (12) that comprises a microprocessor. The switch is designed as a MOSFET or a bipolar transistor. An independent claim is also included for a method for electrically controlling a magnetic actuator.
