Description
Mahnschalter Es sind Anlagen und Vorrichtungen bekannt und geschützt, die zur elektrischen Fernmeldung der Gefährdungsgrenzen von Wasser und Flüssigkeitsständen in Behältern mit und ohne Druck, wie Dampfkessel, Boiler usw., dienen. Sie bestehen aus Schwimmerschaltern verschiedener Konstruktionen, die Signalvorrichtungen; wie Klingeln., Hupen, Fallklappen, Lampen, in und außer Tätigkeit setzen.Reminder switch Systems and devices are known and protected which are used for electrical remote reporting of the hazard limits of water and liquid levels in containers with and without pressure, such as steam boilers, boilers, etc. They consist of float switches of various designs, the signaling devices; like bells, horns, drop flaps, lamps, put in and out of action.
Der Nachteil dieser Anlage besteht darin, daß der Wärter bei ihrem Ansprechen, zwar die Gefahr bemerken kann, aber nicht ge-%wumgen ist, zu quittieren, daß er die Gefahr ,erkannt :hat.The disadvantage of this system is that the keeper at their Speaking, can notice the danger, but is not dared to acknowledge, that he recognized the danger: has.
Diesen. Zwang übt der Mahnschalter, der Gegenstand der Erfindung, aus. Der Mahnschalter ist ein Zeitverzögerungssclialter ,üblicher Bauart und ist so beschaffen und in die Stromkreise der Warnanlage eingeschaltet, daß durch Drücken auf seinen Drwcldmopf oder diesem parallel ;geschaltete weitere Druckknöpfe das :oder die Signale in Ruhestellung :gebracht werden. Nach der Ablaufzeit des Mahnschalters gibt dieser wieder Kontakt, die Signale kommen erneut zum Ansprechen, solange der Gefahrenzustand noch besteht. Der Wärter muß also so lange immer wieder den Mahnschalter betätigen, bis der Gefahrenzustand beseitigt ist.This one. The dunning switch, the subject of the invention, is compulsory the end. The reminder switch is a time delay device, of the usual type and is so designed and switched into the circuits of the warning system that by pressing on his push button or this in parallel; other push buttons switched that : or the signals in rest position: are brought. After the reminder switch has expired if it is in contact again, the signals respond again as long as the Dangerous condition still exists. So the guard has to keep opening the dunning switch for so long press until the dangerous condition has been eliminated.
Dabei ist es vorteilhaft, den Mahnschalter. oder die ihn. auslösenden Druckknöpfe dort anzubringen, wo die Ursache von Gefahrenzuständen, liegt. Kanin an mehreren Stellen oder Teilen der Anlage die Gefahrenursache liegen, :so können an allen diesen Stellen. Mahnschalter und/oder Druckknöpfe angebracht werden.It is advantageous to use the reminder switch. or the him. triggering To attach snap fasteners where the cause of dangerous conditions lies. Rabbit fur the cause of the hazard lies in several places or parts of the system: so can in all of these places. Reminder switches and / or push buttons are attached.
