INTENDED USE
WARNING!
The device may only be used for the applications
indicated in chapter System Description AirLINE Ex
of the operating manual and only in conjunction with
third-party devices or components recommended or
approved by Bürkert.
Observe the instructions in this operating manual, as
well as the conditions of use and permissible data
specied in the chapter System Description AirLINE Ex
/ Technical data.
The proper and safe function of the product depends
on porper transport, storage and installation, and on
careful operation and maintenance. Use in any other
way does not constitute an intended use.
Limitations
Pay attention to any limitations if the system is to be
exported.
The Ex approval
•Is only valid if the modules and components approved
by Bürkert are used in the manner described in the
operating manual.
•The electronic modules may only be employed in
combination with the pneumatic valves approved by
Bürkert. Use in any other way will invalidate the Ex
approval.
6
•The Ex approval will be invalidated if unauthorised
modications are made to the system, the modules or
components.
Foreseeable misuse
•Do not supply aggressive, inammable or liquid media
to the media connections of the system.
•Do not subject the housing to mechanical loads (e. g.
by placing objects on the housing or using the housing
as a step).
•Do not cover the ventilation slots in the housing.
GENERAL SAFETY PRECAUTIONS
DANGER!
Hazard due to high pressure!
Interference with the system will result in an acute risk
of injury.
•Switch o the pressure and depressurise the system
before loosening pipes and modules!
Hazard due to electrical voltage!
Interference with the system will result in an acute risk
of injury.
•Always switch o the power supply before starting
work! Observe all applicable accident prevention and
safety regulations for electrical equipment.
7
Hazardous situations can arise during installation work.
This work may only be carried out by authorised spe-
cialist personnel who have been trained for working in
explosive atmospheres and using suitable tools!
WARNING!
Hazard situations!
Unintentional operation or impermissible damage can
lead to dangerous situations including physical injury.
•Take suitable measures to prevent unintentional opera-
tion or inadmissible damage!
•Ensure that the process is restarted in a dened and
controlled manner after an interruption in the electrical or
pneumatic power supply!
CAUTION!
Electrostatic charges!
The system contains electronic components that react
sensitively to electrostatic discharge (ESD). Touching by
electrostatically charged persons or objects can endan-
ger these components. In the worst case they may be
immediately destroyed or fail after commissioning.
Pay attention also not to touch electronic components
when the supply voltage is switched on.

8
Power supply!
The device may only be operated with direct current. Other-
wise damage may be caused to the system.
Ensure that the device is connected only to a DC
power supply!
CAUTION!
Pressure drop!
The pressure in the system may drop during switching.
•Prevent pressure drops. Design the pressure supply
system with as large a volume as possible.
Note!
Operate the AirLINE
Ex System only when it is in perfect condition and
in according with the operating manual.
Failure to observe this information and unauthorised
intervention in the AirLINE Ex System will void any
liability for us and annuls the guarantees applicable
to the devices and accessories!
The Ex approval is only valid if you the modules and
components of the AirLINE Ex System are operated
in the manner described. Unauthorised modications
will invalidate the Ex approval!

DANGER!
Hazard due to electrical voltage!
The terminal modules (with upright system wiring) are
designed in the explosion-proof class Ex-e (increased
safety).
•When working on the terminal modules, the operating
voltage of the system must be switched o.
•Further information on this can be found in the manual
of the Siemens ET200iSP.

depressurised.
•When using a P shut-p at the corresponding valve
position, the valves can also be exchanged under
pressure.

Group fault display: Yes, locally at the electronic mod-
ule (red LED)
Diagnostic function (can be read out via Probus):
•Channel status diagnosis (channel open, channel short
