Abstract

Die Erfindung betrifft eine Sicherheitsschaltanordnung mit wenigstens zwei in Serie an eine Auswerteeinheit (11) angelegten Öffnungsschaltern (12a, 12b, 12c), wobei die Auswerteeinheit (11) bei Öffnen wenigstens eines der Öffnungsschalter (12a, 12b 12c) ein Sicherheitssignal, insbesondere ein Alarm- und/oder Abschaltsignal auslöst und feststellt, welcher der Öffnungsschalter (12a, 12b, 12c) geöffnet wurde. Die Erfindung besteht darin, daß wenigstens einem und vorzugsweise allen Öffnungsschaltern (12a, 12b, 12c) ein Codesignalgenerator (13a, 13b, 13c) zugeordnet ist, der bei Öffnen des zugeordneten Öffnungsschalters (12a, 12b, 12c) über eine zur Auswerteeinheit (11) führende, allen einen Codesignalgenerator (13a, 13b, 13c) zugeordneten Öffnungsschaltern (12a, 12b, 12c) gemeinsame Leitung, insbesondere eine Diagnose-Leitung (15) oder Sicherheits-Leitungsabschnitte (16a, 16b, 16c), ein für den betreffenden Öffnungsschalter (12a, 12b, 12c) charakteristisches Codesignal an die Auswerteeinheit (11) liefert, welches in der Auswerteeinheit (11) analysiert und als von dem betreffenden Öffnungsschalter (12a, 12b, 12c) kommend erkannt wird.
