Abstract: An elevator system controller controls a drive and optionally further elevator components. The controller includes a circuit having a switch to be monitored, the switch having an input and an output, a signal transmitter unit applying an AC voltage input signal to the input of the switch, and a monitoring unit to record an output signal at an output of the switch. On the basis of a comparison of the output signal with the input signal, the circuit generates a monitoring signal that indicates a switching state of the switch. The switch may be, for example, a door switch connected in series with other safety switches to form a safety chain. Applying the AC voltage signal instead of a conventional DC voltage signal makes it possible to avoid electrical corrosion in the switch and also makes it possible to increase a reliability of a detected switching state of the switch.

Abstract: Example embodiment relate to a device for heating room air and a liquid. Room air enters and exits the device via an air inlet and an air outlet, and the liquid enters and exits the device via a liquid inlet and a liquid outlet. The heat transfer device transfers the thermal energy produced by an energy unit to the liquid in an interaction area of a medium line. A conveying device moves liquid and/or air between a medium container and the medium line. A control unit controls the conveying device. In case the device is intended to heat only room air in an air mode, the control unit, in a preparation step, controls the conveying device such that the conveying device moves air from an air cushion in the medium container through the medium line.

Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.
