摘要： In a process for operating an air-cooled mains supply unit for industrial application, temperatures influenced by outer heat sources and by heat sources arranged in the mains supply unit are measured by thermo-elements and reported to a control system. Temperatures measured by at least two thermo-elements arranged at different measurement points are reported to the control system, and the measured temperatures are compared with temperature patterns. The comparison with known temperature patterns makes it possible to sense the totality of the thermal conditions continuously and to derive therefrom ratings for the control system.

摘要： A light grid detects objects in a monitored area. The grid includes a number of transmitters that emit light rays pulses. A number of receivers, corresponding to the number of transmitters, receive the light rays. Respectively one transmitter is assigned to one receiver to define a light axis. With a clear monitoring area, the light rays emitted by the transmitter impinge on the corresponding receiver. The transmitters and the corresponding receivers are activated cyclically and individually, one after another. An evaluation unit generates a switching signal in dependence on the signals received at the receivers. A control unit coupled between the receivers and the evaluation unit eliminates interfering light shares in the signals received at the receivers. The control unit is deactivated during time intervals in which the transmitters emit transmitting pulses.

摘要： The invention relates to a method for operating a switched mode power supply as an isolating transformer. According to said method, magnetic energy is stored in the core of a transformer during a storage stage via a primary coil that is connected to an intermediate circuit current and the stored magnetic energy is delivered to a load in a subsequent discharge phase, for the most part by means of a secondary coil, a small part of said magnetic energy being discharged on the primary side. The energy that is discharged on the primary side charges a capacitor in such a way that the capacitor current is always held above the secondary current multiplied by the transmittance ratio of the transformer.
