MANUALSwitch box AL 77-1990 Explosion proof

Commissioning Ensure that the switch box correspond to the ordered part speci-fications. If needed contact Axel Larsson. The electrical connection between the RC1990 switch box and the control system is to be established according to the standards for installation. The installer must also refer to the label on the switch box and the EC-type exa-mination certificate (available on request) to ensure that the elec-trical and environmental parameters correspond to the installation requirements. Fit suitable Explosion-proof cable gland, EEx d approved for EEx d switch box and EEx e approved for EEx i switch box. Extra cable entries with EX glands may be required if solenoid valves are to be connected.

Note: Cable entries in Explosion-proof design suitable for the cable type and ambient condition and/or a plug are demanded for approved application.

Maintenance1. Check that the threaded gaps between the cover and the housing (7) do not have any damage, due to mechanical or corrosion affection. 2. If needed touch up the painting.

3. Check the condition of the cable glands and that they are correctly mounted.

4. If necessary protect the gaps and threads against corrosion with nonhardening grease. KlübercIsoflex Topas NCA 52 or identical. The gaps and threads must not be painted or treated with silicone oil based grease.

5. Check that O-rings for cover (2) and shaft (8) are intact. Damaged O-rings must be replaced with genuine spare parts only.

6. Check that all screws and the cover are correctly tightened. Secure the cover (2) with the locking screw (1).

Mounting1. Operate the actuator to the ”closed valve position”.

2. Fasten the Namur console (10) to the switch box (7) with 4 pcs M6 screws according to drawing 003146.

3. Dismantle the cover (2) on the switch box. Loosen the locking screw (1), unscrew the cover and lift it straight up.

4. Mount the RC1990 switch box shaft (8) through the hole in the

box. The shaft journal must go through the brass bearing bush (9). Turn the shaft so that it aligns with the groove in the actuator stem (13).

5. Mount the RC1990 box and console with the shaft in the groove on the top side of the actuator stem (13).

Montering

1. Ställ manöverdonet i ”stängt ventilläge”. 2. Skruva fast Namur konsolen (10) på RC1990 boxen (7) med 4 st M6 skruvar enligt ritning 003146.

3. Demontera locket (2). Lossa stoppskruven (1), skruva loss locket och lyft av det rakt upp.

4. Montera axeln (8) genom mässingsbussningen (9) i botten på RC1990 boxen. Vrid axeln så att den står längs med spåret i donaxeln.

5. Montera RC1990 box och konsol med axeln i spåret på ovansidan av manöverdonets spindel (13).

6.Skruva fast konsolen med 4 st skruvar (12) på donets ovansida och centrera enheterna med varandra före åtdragning av skruvarna.

7.Träd de två kammarna (5) över axeln (8). Kammarna vänds enligt ritning 003146.

8.Justering av undre brytare, som indikerar ”stängt ventilläge”: Vrid undre kammen (5) medurs så att brytaren påverkas. När klickljud hörs (endast me- kaniska brytare) låses kammen med insexskruven (3).

9.Ställ manöverdonet i öppet läge.

10. Justering av övre brytare, som indikerar ”öppet ventilläge”: Nu skall axeltappens nyckel- grepp (13) stå i donets längsriktning. Vrid den övre kammen moturs så att brytaren påverkas. När klickljud hörs (endast mekaniska brytare) låses kammen med insexskruven.

11. Montera kabelförskruvning/ar och om det behövs även blindplugg. Anslut inkommande kabel enligt elschemat som är fäst på RC1990 lockets insida. Spänningen måste vara frånslagen.

12. Skruva tillbaka locket (2) på RC1990 boxen och säkra med låsskruv (1).

Demontering

1.Bryt spänningen till RC1990 boxen och avlufta manöverdonet.

2.Demontera locket (2). Lossa stoppskruv (1). Skruva loss locket och lyft av det rakt upp.

3.Ta loss kablarna från kopplingsplinten och jordningen. Öppna kabelförskruvningen och dra ur kablarna.

4.Lossa de fyra skruvarna (12) som håller Namur konsolen (10). Lyft bort konsolen och RC1990 boxen från donet. Skruva tillbaka locket (2) och lås med stoppskruv (1). Plugga ingångarna på RC1990 boxen för skydd mot damm och smuts.

9. Operate the actuator to the ”open valve position”.

10. Adjustment of the upper switch for ”open valve position

indication: The slot in the actuator stem (13) will now align with actuator long side. Turn the upper cam anti-clockwise until the

switch is actuated. When a click is heard (only mechanical

switches), the cam must be locked with the grubvscrew (3).
