Definitions

  • a sensor connected to a control device of the drive, such as an electrical sensor for detecting a predetermined position of the fluid displacement element or a connected movable drive part such as a push rod, wherein the sensor can be provided for the transmission of a determined position information to the control device.
  • the rear dead center of the fluid displacement element can be detected by means of the sensor and stored in the control for driving the drive.
