Abstract (en)
[origin: EP2560180A2] The device (1) has a reset input (IN) for starting the device after triggering a safety function of the device, where the device is operable in various start modes. An evaluation circuit (2) is connected with the reset input to detect application of a start signal. The circuit selects a start mode for the device in correspondence with the detected start signal. The circuit comprises a sampling unit (4) for sampling the start signal at the reset input and detecting a sequence of sample values. The circuit detects a voltage level, a voltage slope or a clocked signal as the start signal.
