Method and device for reliably monitoring a closed position of two parts moveable relative to one another |
摘要 |
A device for reliably monitoring a closed position of two parts which can move relative to one another has an actuator and a sensor. The device is particularly used for monitoring the closed position of a protective door installed for safeguarding a technical installation which operates in an automated fashion. The sensor has a receiver circuit at an input side, which circuit generates a defined receiver circuit signal when a switching distance between the sensor and the actuator is fallen short of. A detector circuit provides an enable signal when the defined receiver circuit signal is present. According to one aspect of the invention, a test element is provided for selectively suppressing the defined receiver circuit signal.
