2/2-directional or 3/2-shut-off valve SOV ,
electrically operated
3
Mount electrical connector with C-shape connection
1. Place the seal (b) on the C-shape connector.
2. Mount the electrical connector (c) and screw on tight.
Function:
W
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.
W
P1 is shut off and P2 discharged for compressed air relief.
W
If pressure is supplied to P1, the valve can be manually switched via the manual
override (d) (inching function).
4
Attach connecting cable to connection M12
O Screw together the M12 plug (a) and electrical connector (b).
Function:
W
On supplying voltage to the coil the valve switches to opening 1
W
If pressure is supplied to P1, the valve can be manually switched via the manual
override (c).
5
Mount selected DO16 pilot valve
1. Insert the seal (b) in the recess (a).
2. Mount the pilot valve (c) and screw on tight (d).
6
Mounting transition plate AS CNOMO
1. Insert the seals (b) in the recess (a).
2. Mount the transition plate (c) and tighten the screws (d).
7
Mounting pilot valve DO30
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 then with
the knurled nut (g).
3. Open the electrical connector, push the line through (n), (m), (l) and the opening
und fasten the wires to the terminals.
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 electrical
connector with the screw (k).
8
Mounting coil for explosive areas
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 then 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 movements.
O Please ensure when commissioning a system without a SSU filling unit that
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, otherwise,
water may condense in the housing.
2. Check that all the electrical and pneumatic connections are allocated or closed.
Only commission fully installed products.
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
regulators with fully automatic condensate drains ("open without pressure" version),
as they may prevent component switching.

Pneumatically operated
Adjust filling time
The filling valve prevents a sudden build-up of pressure when the system
is commissioned. 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).
10
Pneumatically operated, adjustable filling time
and change-over pressure
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.
2.
b) Adjust filling time
O Adjust filling time as described in
11
Filling valve, pneumatically operated, with electrical priority circuit
Adjust filling time, force switching
O See description under Pneumatically operated > Adjust filling time
Force switching
Forced switching can be initiated before the set filling time (a) is reached (b) via
an electrical pulse (see SOV 3/2-directional valve – electrically operated*).
12
SSU filling unit
The filling unit combines a shut-off and filling valve.
* Exhaust
AS2: Exhaust via rear.
AS1/3/5: Exhaust via bottom.
6 Service and Repairs
Cleaning and servicing
W
Close all openings with suitable safety devices so that no cleaning agent
can enter into the system.
W
Never use solvents or aggressive detergents. Only clean the product using
a slightly damp cloth. Only use water and, if necessary, a mild detergent.
W
Do not use high-pressure cleaners for cleaning.
W
Do not use compressed air for cleaning (blowing off) the maintenance unit
or equipment.
7 Decommissioning, Disassembly,
Replacement
Danger of injury in case of disassembly or replacement under pressure
or voltage
Disassembling or replacement when under pressure or electrical voltage
may lead to injuries and damage to the product or system components.
O Make sure that the relevant system part is not under voltage or pressure
before you disassemble the product or replace parts.
O Protect the system against being switched on.
Danger of burns!
The surfaces of adjacent system components can become hot during operation.
O Let the system component cool off before disassembling it.
