– Connect terminals 18, 19 and 20 in accordance with

requirements; voltage < 50 V.

3. Determine the direction of rotation and, if necessary, correct it.

Determining the direction of rotation

The internal wiring means that the direction of rotation (looking

through the drive towards the output shaft) and limit switches are

assigned as follows:

• If the mains voltage is present at terminal 2, the output shaft

rotates anticlockwise (in the direction "open/max.").

– This direction of rotation is restricted by the upper switch

(max.). If the switch is activated, the mains voltage is

present at terminal 4.

• If the mains voltage is present at terminal 3, the output shaft

rotates clockwise (in the direction "close/min.").

– This direction of rotation is restricted by the lower switch

(min.). If the switch is activated, the mains voltage is present

at terminal 5.

• If the drive rotates in the opposite direction to the control

commands, swap over the connections of terminals 2 and 3.

Close the hood again and tighten the hood screws.

2.2.7 Chlorentnahme

Vor der Entnahme

• Die Chlorbehälter müssen mindestens 8 Stunden im Lager-

raum verbleiben, damit der Inhalt sich an die Umgebungs-

temperatur anpassen kann.

• Chlorfässer auf der Abstützung drehen, bis Tauch- und Steig-

leitung vertikal ausgerichtet sind (die Markierungen auf dem

Fass beachten).

• Die Dichtheit prüfen.

Anschluss

• Behälter vor Umfallen oder Wegrollen schützen!

• Die Leitungen und das Entnahmesystem mit trockenem Stick-

stoff oder trockener Luft trocknen.

• Es dürfen keine Fremdkörper in die Anlage gelangen.

• Die Anschlussleitung mit neuen Dichtungen versehen.

• Den Behälter anschließen.

• Langsam das Behälterventil öffnen.

Entnahme von Chlorgas

Bei einem höheren Chlorbedarf müssen mehrere Behälter mit

derselben Temperatur über Sammelleitungen angeschlossen

werden.

Entnahme von flüssigem Chlor

• In Chlorungsanlagen ist eine Entnahme flüssigen Chlors nur

aus Chlorfässern möglich.

• Dabei muss ein Verdampfer verwendet werden.

• Entnahme von Chlorgas: Einen Restdruck von ca. 2 bar

belassen.

• Entnahme von flüssigem Chlor: Einen Restdruck von ca. 4 bar

belassen.

Nach der Entnahme

• Das Behälterventil schließen.

• Den Behälter von der Anlage trennen.

• Die Ventilschutzmuttern anschrauben.

• Die Schutzkappe aufschrauben.

2.3 Dichtheitsprüfung

Vor der Inbetriebnahme die gesamte Anlage auf Dichtheit über-

prüfen. Siehe hierzu Abschnitt 5.2.2 Dichtheitsprüfung der Vaku-

umleitungen.
