Abstract

Die Erfindung betrifft eine Sicherheitsschaltung für medienbetriebene Verbraucher, wie Dampf- oder Gasturbinen, mit mindestens einem ersten Magnetventil (1.1), das auf einen Fluidkreis (10), insbesondere Hydraulikkreis, einwirkt, an den eine Betätigungseinrichtung (9) anschließbar ist, die auf das Betriebsverhalten des Verbrauchers mit einwirkt. Dadurch, das mindestens ein weiteres Magnetventil (1.1, 1.3) vorhanden ist, das zumindest mit einem der anderen Magnetventile (1.1) derart verschaltet ist, dass erst bei gleichzeitiger Ansteuerung mindestens zweier Magnetventile (1.1,1.2,1.3) mindestens ein in den Fluidkreis (10) geschaltetes Steuerventil (2.1) auf die Betätigungseinrichtng (9) einwirkt, ist die Möglichkeit der permanenten Überprüfbarkeit gegeben bei gleichzeitiger Realisierung der Sicherheitsfunktion. Die Erfindung betrifft des weiteren ein Verfahren zum Betrieb der Sicherheitsschaltung.
