The invention relates to a monitoring and warning apparatus for automatic processing apparatuses, in particular robots. Reactance-determining elements are arranged as sensors on the movable parts of the robot. If the robot arm approaches an object, detuning of the sensor circuit occurs. In that way, it is possible to produce a monitoring or stop signal. A central supply with HF-signals and current permits central monitoring of the function of the sensor circuits and at the same time triggering of warning signals when the sensor approaches an object. That is achieved in that the warning signals derived from sensor signals are used to connect additional loads into the circuit which is supplied from the central current supply means. Therefore, by monitoring the current consumption, it is possible to detect both failure of individual sensor circuits and also the approach of an object to a sensor. |
