Intended use

The AES series bus coupler and AV series valve drivers are electronic components developed
for use in the area of industrial automation technology.
The bus coupler connects I/O modules and valves to the PROFIBUS DP fieldbus system. The bus
coupler may only be connected to valve drivers from AVENTICS and I/O modules from the
AES series. The valve system may also be used without pneumatic components as a stand-alone
system.
The bus coupler may only be actuated via a programmable logic controller (PLC), a numerical
controller, an industrial PC, or comparable controllers in conjunction with a bus master interface
with the fieldbus protocol PROFIBUS DP.
AV series valve drivers are the connecting link between the bus coupler and the valves. The valve
drivers receive electrical information from the bus coupler, which they forward to the valves
in the form of actuation voltage.
Bus couplers and valve drivers are for professional applications and not intended for private use.
Bus couplers and valve drivers may only be used in the industrial sector (class A). An individual
license must be obtained from the authorities or an inspection center for systems that are to be used
in a residential area (residential, business, and commercial areas). In Germany, these individual
licenses are issued by the Regulating Agency for Telecommunications and Post
(Regulierungsbehörde für Telekommunikation und Post, Reg TP).
Bus couplers and valve drivers may be used in safety-related control chains if the entire system
is geared toward this purpose.
Observe the documentation R412018148 if you use the valve system in safety-related control
chains.
2.2.1

Use in explosive atmospheres

Neither the bus coupler nor the valve drivers are ATEX-certified. ATEX certification can only be
granted to complete valve systems. Valve systems may only be operated in explosive atmospheres
if the valve system has an ATEX identification!
Always observe the technical data and limits indicated on the rating plate for the complete unit,
particularly the data from the ATEX identification.
Conversion of the valve system for use in explosive atmospheres is permissible within the scope
described in the following documents:
Assembly instructions for the bus couplers and I/O modules
Assembly instructions for the AV valve system
Assembly instructions for pneumatic components
