Vorrichtung zur Erkennung eines unzulässigen Betriebszustandes

摘要

The invention relates to a device for detecting an inadmissible operating state, which comprises detection means (12) for detecting at least one supply voltage (UB), evaluation means (18) that evaluate the profile of the supply voltage (UB) and that detect an inadmissible operating state on the basis of voltage variations of the supply voltage (UB) and trigger an alarm. According to the invention, the evaluation means (18) detect at least one piece of information about the operating state of an electrical load (36, 38) supplied by the supply voltage (UB) and trigger the alarm in accordance with this information.
