2.1

About this chapter

The product has been manufactured according to the accepted rules of current technology. Even so,
there is risk of injury and damage to equipment if the following chapter and safety instructions of
this documentation are not followed.
Read these instructions completely before working with the product.
Keep this documentation in a location where it is accessible to all users at all times.
Always include the documentation when you pass the product on to third parties.
2.2

Intended use

The devices described in this documentation are electronic components developed for use in the
area of industrial automation technology. They are designed exclusively for use with AV series valve
systems.
The output modules convert output signals from the controller into an analog output signal (current
or voltage). The input modules transmit analog input signals from sensors (current or voltage) to the
controller via the fieldbus connection. The combination modules can be used as input and output
modules simultaneously. The channels of the combination modules behave like the channels of the
input and output modules.
The devices are intended for professional use only and not for private use. The modules may only be
used for industrial applications (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).
The devices may be used in safety-related control chains if the entire system is geared toward this
purpose.
2.2.1

Use in explosive atmospheres

The devices are not 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
2.3

Improper use

Any use other than that described under Intended use is improper and is not permitted.
Improper use of the I/O modules includes:
Use as a safety component
Use in explosive areas in a valve system without ATEX certification
The installation or use of unsuitable products in safety-relevant applications can result in
unanticipated operating states in the application that can lead to personal injury or damage to
