4 Assembly
System is operating under pressure
Working on the system when under pressure could lead
to injuries and damage!
O Depressurize all relevant system parts before
working on the system.
Assembling the valve system
1
3. Insert both tie rods (12, 13) with the torsion protection
into the subbase (1).
4. Insert the tie rod mounting screws (9) with washers
into the subbase (1) and tighten them slightly.
5. Insert the valve plate first into the upper tie rod and
then tilt it downward until it engages in the lower tie
rod.
6. Slide the valve plate on the tie rods toward the subbase
until the valve plate engages in place.
If blanking plates or partition/supply plates are to
be used, the covers (available separately) must be
installed so that they engage in the previously
installed valve plates. After this, the blanking plate
or partition/supply plate can be installed.
7. Proceed in the same manner with the following valve
plates, making sure that they also engage in the
previously installed valve plate.
8. Install the end plate (8) on the tie rods (12, 13) and then
insert the tie rod mounting screws (9).
9. Tighten the tie rod mounting screws (9) on the subbase
(1) and the end plate (8) evenly
(tightening torque = 1,3
Exchanging the valve plates,

occupying reserve positions
1. Loosen the tie rod mounting screws (9) on the subbase
(1) and the end plate (8) by several turns.
2. Pull apart the valve plates (5) or blanking plates (2) at
the desired location. Please note during removal that
the centering pins on both sides of the valve plates and
blanking plates must be exposed.
3. Remove the valve plate (5) or blanking plate (2) by
rotating it around the upper tie rod (13). The cover
element (6) can then be loosened from the valve plate
by applying light pressure, and the cover will remain in
the VS.
4. Insert the new valve plate into the upper tie rod (13)
and tilt the valve plate downward. The valve plate must
engage in the lower tie rod (12) as well as in the cover
element (6).
5. Slide the valve plates (5) or blanking plates (2) back
together.

1. Loosen and remove the tie rod mounting screws (9) on
the end plate (8).
2. Remove the end plate (8).
3. Screw the tie rod extensions (4) into the tie rods (12,

4. Insert the valve plate into the upper tie rod (13) and
then tilt it downward until it engages in the lower tie
rod (12).
5. Slide the valve plate on the tie rods toward the subbase
until the valve plate engages in the previous valve
plate.
6. Install the end plate (8).
7. Insert the tie rod mounting screws (9) with washers

Electrical connection

Each valve can be directly wired in the VS LS04 SW. This
is done by inserting the stripped cable ends into the spring
clamps on the rear of the VS.
O Take precautions against overvoltages in signal-
carrying lines that are longer than 30 m.
O During each valve sequence, only one neutral wire
has to come into contact with any of the valves. Any
contact with additional valve plates occurs
internally.
O For the VS LS04 SW with an operating voltage of
12 V DC, limit the maximum number of solenoids per
neutral connection to 20.
