1 About this documentation

1.1 Documentation validity

This documentation applies to components of the AV series that are used in
safety-related control chains. This documentation is intended for programmers,
electrical planners, pneumatic engineers, service personnel and plant operators.
This documentation contains important information for evaluating fault exclu-
sion under certain conditions for valve systems of the AV series.

1.2 Required and supplementary documentation

Do not start up valve systems of the AV series in safety-related control chains
u
until you have received the documentation on the valve system and the indi-
vidual components and have read and understood it.
All assembly instructions and system descriptions for the AES and AV
series, as well as the PLC configuration files, can be found on the CD
R412018133.

from the backplane into current for the solenoid coil

1.5 Abbreviations

This documentation uses the following abbreviations:
Table 2: Abbreviations
Abbreviation Meaning
AES Advanced Electronic System
AV Advanced Valve
I/O module Input/Output module
IS12-PD ISO valve with slider position detection
PL Performance Level
PLC Programmable Logic Controller or PC assuming control functions
UA Actuator voltage (power supply for valves and outputs)
UAoff Message that the actuator voltage UA has fallen below the value
of the switch-off voltage of the valves. The valves are switched off
electrically.
UAon Message that the actuator voltage UA has fallen below the value
of the switch-on voltage of the valves. The valves cannot be
switched on electrically.
UL Logic voltage (power supply for electronic components and sen-
sors)

2 Safety instructions

2.1 About this chapter

The product has been manufactured according to the accepted rules of current
technology. Even so, there is danger of injury and damage to equipment if the
following chapter and safety instructions of this documentation are not followed.
1. Read these instructions completely before working with the product.
2. Keep this documentation in a location where it is accessible to all users at all
times.
3. Always include the operating instructions when you pass the product onto
third parties.
4. Observe ISO 4414 for the safe handling of pneumatics.

2.2 Personnel qualifications

The work described in this documentation requires basic electrical and pneu-
matic knowledge, as well as knowledge of the appropriate technical terms. In or-
der to ensure safe use, these activities may therefore only be carried out by quali-
fied technical personnel or an instructed person under the direction and supervi-
sion of qualified personnel.
Qualified personnel are those who can recognize possible dangers and institute
the appropriate safety measures, due to their professional training, knowledge,
and experience, as well as their understanding of the relevant regulations per-
taining to the work to be done. Qualified personnel must observe the rules rele-
vant to the subject area.

2.3 Use in safety-related control chains

Bus couplers and valve drivers may be used in safety-related control chains for
the safety function "Safety-related stop function and other safety functions ini-
tiated by a protective device" if the entire system is geared toward this purpose.
