Sov 2/2-Directional Or 3/2-Directional Valve, Electrically Operated; Mount Electrical Connector With C-Shape Connection; Attach Connecting Cable To Connection M12; Mount Selected Do16 Pilot Valve - Emerson AVENTICS AS1 Instrucciones De Servicio

Function:
• On applying control pressure > 2.5 bar the valve switches to
opening 1 → 2.
• P1 is shut off and pressure P2 exhausted for compressed air pressure relief.
The control pressure depends on the operating pressure P1
(see online catalog)
5.5 SOV 2/2-directional or 3/2-directional valve, electrically
operated*

5.5.1 Mount electrical connector with C-shape connection

See Fig. 3
1. Place the seal (b) on the C-shape push-in fitting.
2. Mount the electrical connector (c) and screw on tight.
Function:
• On supplying voltage to the coil and pressure to P1 (electrical:
2.5 bar < P1 < 10 bar, pneumatic: 2.5 bar < P1 < 16 bar) the valve switches to
opening 1 → 2.
• P1 is shut off and P2 exhausted for compressed air pressure relief.
• If pressure is supplied to P1, the valve can be manually switched via the man-
ual override (d) (inching function).

5.5.2 Attach connecting cable to connection M12

See Fig. 4
Screw together the M12 plug (a) and electrical connector (b).
u
Function:
• On supplying voltage to the coil the valve switches to opening 1 → 2.
• If pressure is supplied to P1, the valve can be manually switched via the man-
ual override (c).

5.5.3 Mount selected DO16 pilot valve

See Fig. 5
1. Insert the seal (b) in the recess (a).
2. Mount the pilot valve (c) and screw on tight (d).

5.5.4 Mounting transition plate AS CNOMO

See Fig. 6
1. Insert the seals (b) in the recess (a).
2. Mount the transition plate (c) and tighten the screws (d).

5.5.5 Mounting pilot valve DO30

See Fig. 7
1. Mount the DO30 pilot valve (b) on the transition plate and fasten it tight with
the supplied screws (d).
2. Push the coil (e) and washer (f) onto the valve shaft (b), and secure them with
the knurled nut (g).
3. Open the electrical connector, push the line through (n), (m), (l) and the
opening, and fasten the wires to the clamps.
4. Close the electrical connector.
5. Place the seal (h) on the coil (e).
6. Mount the electrical connector (i) on the coil contacts (e), and secure the elec-
trical connector with the screw (k).

5.5.6 Mounting coil for explosive areas

See Fig. 8
1. Mount the pilot valve (c) on the transition plate (b), and fasten it tight with the
supplied screws (e).
2. Push the coil (f) and washer (g) onto the valve shaft (c), and secure them with
the knurled nut (h).

Sudden rise in pressure during commissioning!
The system is exposed to sudden pressure on commissioning if no SSU filling
unit is used! This may result in dangerous erratic cylinder motions.
Please ensure when commissioning a system without a SSU filling unit that
u
the cylinders are in their end position or that no danger can emit from
those not in end position.
During commissioning
1. Let the product acclimatize for several hours before commissioning, other-
wise, water may condense in the housing.
2. Check that all the electrical and pneumatic connections are allocated or
closed. Only commission fully installed products.

5.6 Filling valve SSV

Filling valves or units must not be mounted in front of open consumers (such as
nozzles, air barriers, air curtains or condensate reservoirs) of filters and filter regu-
lators with fully automatic condensate drains ("open without pressure" version),
as they may prevent component switching.

5.6.1 Pneumatically operated

See Fig. 9
Adjust filling time
The filling valve prevents a sudden build-up of pressure when the system is com-
missioned. The filling time can be changed on the adjustment screw. (The screw
position varies depending on the series.)
1. Remove the adjustment screw lock (a) (if fitted).
2. Turn the adjustment screw (e.g. with a screwdriver) in a clockwise direction to
lengthen the filling time or in an anti-clockwise direction to shorten the filling
time.
3. Press the adjustment screw lock (a) into the adjustment screw (if fitted).
5.6.2 Pneumatically operated, adjustable filling time, and change-
over pressure
See Fig. 10
a) Adjust change-over pressure
1. Push up the handwheel (to unlock).
2. Set the required change-over pressure by turning the handwheel.
3. Push down the handwheel (to lock).
This reactivates the filling valve.
b) Adjust filling time
See description under Pneumatically operated > Adjust filling time.

5.6.3 Filling valve with electrical priority circuit

See Fig. 11
Adjust filling time
See description under Pneumatically operated > Adjust filling time.
u
Force switching
An electrical impulse forces the filling valve to switch over. Please note that if the
electrical control is removed, only the throttled cross-section is available. For un-
throttled operation, the filling valve must therefore be permanently electrically
actuated
(see "SOV 2/2-directional or 3/2-directional valve, electrically operated*").

5.6.4 Filling valve with pneumatic priority circuit

See Fig. 12
Adjust filling time
See description under Pneumatically operated > Adjust filling time.
u
Force switching
A pneumatic impulse forces the filling valve to switch over. Please note that if the
pneumatic control is removed, only the throttled cross-section is available. For
unthrottled operation, the filling valve must therefore be permanently pneumati-
