Title
(DE) ÜBERWACHUNGSMODUL ZUR SCHUTZLEITERÜBERWACHUNG
(EN) MONITORING MODULE FOR PROTECTIVE-CONDUCTOR MONITORING
(FR) MODULE DE SURVEILLANCE DE CONDUCTEURS DE PROTECTION
Abstract
(DE) Das Überwachungsmodul (50) zur Schutzleiter-Überwachung weist eine Überwachungsschaltung (2) auf, über die überprüft wird, ob ein Schutzleiter ordnungsgemäß angeschlossen ist. Bei Detektion einer Schutzleiterunterbrechung identifiziert die Überwachungsschaltung (2) dies als einen ersten Fehlerfall (F1) und gibt ein erstes Fehlersignal (S1) aus. Die Überwachungsschaltung (2) ist ergänzend zur Speicherung des ersten Fehlerfalls (F1) ausgebildet und gibt im Falle einer nur temporären, nicht mehr vorliegenden Schutzleiterunterbrechung ein zweites Fehlersignal (S2) aus. Durch diese Maßnahme wird ein verbesserter Personenschutz auch beispielsweise bei Wackelkontakten etc. erzielt.
(EN) The invention relates to a monitoring module (50) for protective-conductor monitoring having a monitoring circuit (2), by means of which it is checked whether a protective conductor is properly connected. If a protective-conductor interruption is detected, the monitoring circuit (2) identifies this as a first fault case (F1) and outputs a first fault signal (S1). The monitoring circuit (2) is designed additionally to store the first fault case (F1) and outputs a second fault signal (S2) in the event of an only temporary protective-conductor interruption that is no longer present. By means of this measure, improved protection of persons is achieved, even in the event of, for example, intermittent contacts, etc.
(FR) L'invention concerne un module de surveillance (50), servant à surveiller des conducteurs de protection, qui comporte un circuit de surveillance (2) qui vérifie si un conducteur de protection est correctement raccordé. En cas de détection d'une interruption du conducteur de protection, le circuit de surveillance (2) identifie la chose comme un premier cas de défaut (F1) et délivre un premier signal de défaut (S1). Le circuit de surveillance (2) est en outre adapté pour mémoriser le premier cas de défaut (F1) et, dans le cas d'une interruption du conducteur de protection qui n'est que temporaire et qui n'est plus présente, il délivre un deuxième signal de défaut (S2). Ceci assure une protection améliorée des personnes, y compris par exemple en présence de contacts intermittents etc.
