12 Conversion of the Valve System
Danger of explosion caused by defective valve system in an explosive at-
mosphere!
Malfunctions may occur after the configuration or conversion of the valve sys-
tem.
After configuring or converting a system, always perform a function test in
u
a non-explosive atmosphere before recommissioning.
This chapter describes the structure of the complete valve system, the rules for
converting the valve system, the documentation of the conversion, as well as the
re-configuration of the valve system.
The assembly of the components and the complete unit is described in
the respective assembly instructions. All necessary assembly instruc-
tions are included as printed documentation on delivery and can also
be found on the CD R412018133.
12.1 Valve system
The AV series valve system consists of a central bus coupler that can be extended
towards the right to up to 64 valves and up to 32 associated electrical compo-
nents, see section g 12.5.3. Impermissible configurations.
Up to 10 input and output modules can be connected on the left side. The unit
can also be operated without pneumatic components, i.e. with only a bus coupler
and I/O modules, as a stand-alone system.
The following figure shows an example configuration with valves and I/O mod-
ules. See g Fig. 11.
Depending on the configuration, your valve system may contain additional com-
ponents, such as pneumatic supply plates, electrical supply plates, or pressure
regulators, see section g 12.2. Valve zone.

12.2 Valve zone
The figures below show the components as illustrations and symbols,
see section g 12.5. Conversion of the valve zone.
12.2.1 Base plates
The valves from the AV series are always mounted on base plates that are assem-
bled into blocks so that the supply pressure is applied to all valves.
The base plates are always 2x or 3x base plates for two or three single or double
solenoid valves.

12.2.2 Transition plate
The transition plate (29) has the sole function of mechanically connecting the bus
coupler to the valve zone. It is always located between the bus coupler and the
first pneumatic supply plate.

12.2.3 Pneumatic supply plate
Pneumatic supply plates (30) can be used to divide the valve system into sections
with different pressure zones, see section g 12.5. Conversion of the valve zone.

12.2.4 Electrical supply plate
The electrical supply plate (36) is connected to a supply board. It can feed in an
extra 24 V power supply for all valves located to the right of the electrical supply
plate via an integrated 4-pin M12 connection. The electrical supply plate moni-
tors the additional power supply (UA) for low voltage.
