Conversion of the Valve System

12 Conversion of the Valve System
Danger of explosion caused by defective valve system in an explosive atmosphere!
Malfunctions may occur after the configuration or conversion of the valve system.
After configuring or converting a system, always perform a function test in 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 instructions 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 components (see section 12.5.3 "Impermissible
configurations" on page 119). 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.
Fig. 7 shows an example configuration with valves and I/O modules. Depending on the configuration,
your valve system may contain additional components, such as pneumatic supply plates, electrical
supply plates, or pressure regulators (see section 12.2 "Valve zone" on page 107).
