Description
Zunktion der Abfallsicherung bei Stromausfall. Function of waste protection in the event of a power failure.
Ein Stahlkeil, mit der aus der Zeichnung erkennbaren Form, wird auf die untere auflageschiene eines Rolltores oder einer Jalousie BO anebracht, daß er frei beweglich ist Eine Stahlfeder, die un den Rückzugstößel angebracht ist, schiebt ihn durch eine in der Seitenwange befindliche Öffnung nach außen. Bei leichtem Anziehen des Gitters rastet er in die erste der in den Führungsschienen regelmäßig vorhandenen Absfandsauflageöffnungen.Der Aufzug, der durch einen Elektromotor erfolgt, drückt den Keil dort, wo die Führungsschiene vollmetallisch ist, in die glatte Lage der Seitenwange. Dort, wo sich die Öffnungen befinden, drückt die Feder um den Rückzugstößel den Keil wieder in die nächsthöhere Auflageößfnung der Führungsschiene. Bei Stromausfall oder Antriebariß wird so ein Abfallen des Gitters verhindert.A steel wedge with the shape shown in the drawing is opened the lower support rail of a roller shutter or a blind BO attached that it is freely movable A steel spring that is attached to the retraction ram, pushes it out through an opening in the side cheek. With easy When the grille is tightened, it snaps into the first of the guide rails regularly The elevator, which is operated by an electric motor, presses the wedge into the smooth position where the guide rail is fully metallic the sidewall. The spring presses around the retraction ram where the openings are the wedge back into the next higher support opening of the guide rail. In the event of a power failure or drive crack, this prevents the grille from falling off.
Wird nun die "Ab"-Taste des Gitters gedrückt, so wird einmal Stellung "Auf" durch einen Öffner unterbrochen, Schutz C@ zicht an und der Sicherungsstromkreis wird unter Spannung gesetzt. Der Strom fließt über den, wie im Stromlaufplan ersichtlich, niedergehaltenen Öffner, der über einen Rutscher (Laufrad) von der Antriebskette gehalten wird, zur Magnetspule (Relais) und zu Schuts C3. Die Belaisspule zieht durch den Rückzugstößel den Einrastkeil an, Das Gitter kann abwärts gleiten. Bei Stromausfall entiagnetisiert sich die Spule und läßt den Keil durch die Peder hinausschlagen. Gleiches geschicht, wenn die Antriebskette reißt, da dann der Schleifkontakt sich öffnet und der Stromkreis unterbrochen wird. Sollte das 3-Phasennetzteil, das den Sicherungsstromkreis speist, auefallen, so kann weder das Relais noch Schutz C3 anziehen. Das hätte zur Folge, daß der Sicherungskeil einrastet und der Antriebsmotor nicht läuft.If the "Down" key of the grid is now pressed, it becomes position once "Open" interrupted by an NC contact, protection C @ zon and the fuse circuit is put under tension. The current flows through the, as can be seen in the circuit diagram, The opener held down by a slide (impeller) from the drive chain is held, to the solenoid (relay) and to Schuts C3. The belais coil pulls the locking wedge with the retraction ram. The grille can slide downwards. at If there is a power failure, the coil is de-diagnosed and the wedge is knocked out by the peder. The same thing happens if the drive chain breaks, as the sliding contact is then closed opens and the circuit is interrupted. If the 3-phase power supply that supports the Fuse circuit feeds, in the event of a failure, neither the relay nor protection C3 attract. This would result in the locking wedge and the drive motor engaging not running.
Sollte ein Ein- oder Zweiphasenausfall während des Betriebes sein, so muß der leistungsselbstschalter mit Arbeitsstrom-, Übe@@sromschnell-und Bimetallauslöser auslösen. laut wäre auch das dahinter angeklemmte Netzteil für die Sicherheitsstromkreisversorgung spannungslos. Ein Abfallen des Gitters wäre verhindert.Should there be a one- or two-phase failure during operation, The circuit breaker must have an operating current, Übe @@ sromschnell and bimetallic release trigger. The power supply unit connected behind it for the safety circuit supply would also be loud tension-free. The grid would be prevented from falling off.
Die Spannungen zu m Relais können durch bewegliche Leitungen oder isoliert montierte Schleifkontaktleisten geführt werden. Daß hierbei die örtlichen VDE- Vorschriften eingehalten werden müssen, versteht sich von selbst. Natürlich müssen bei gewichtigen Toren und Gitter die Keile une Halterungen beidseitig angebracht und nach Verhältnis angepaßt werden. Aus diesem Anpassungsgrund enthalten die Pläne auch keine maße und Spannungsangaben.The voltages to m relays can be made by moving lines or insulated mounted sliding contact strips can be guided. That here the local It goes without saying that VDE regulations must be adhered to. Of course the wedges and brackets must be attached on both sides for heavy gates and grilles and adjusted according to the ratio. For this reason, the plans contain also no dimensions and voltage information.
