Connection of the pressure supply
Connect the compressed air supply to the ports P/1 of
the supply modules.
The largest possible lines should be used for the supply in order
to avoid pressure drops. With larger AirLINE Ex systems and
applications with high consumptions, the compressed air supply
should be connected to the right-hand and left-hand supply
slices, optionally also to additional middle supply slices.
Close P/1 ports not used with plugs.
Connection of the exhaust air
Connect the exhaust air to the ports R/S-3/5 of the
supply modules.
This connection should be made with the largest possible
lines and possibly silencers with high flow rates in order to
avoid back-pressures. Connect the exhaust air preferably to
the right-hand and left-hand supply slice, optionally also to
an additional middle supply slice.

Pilot exhaust air / auxiliary control air
Depending on which valves you operate on the AirLINE Ex
System, port X is used as follows:
Standard valves:
In this case the exhaust air from the pilot control valves is
discharged separately from the R/S-3/5 port to port X. This
avoids problems in the event that higher back-pressures occur
in the R/S-3/5 channel. This connection should be made with
the largest possible lines and possibly silencers with high fl ow
rates in order to avoid back-pressures.
Valves with auxiliary control air:
In the case of valves that are to be employed for a wider
range of pressures, the pilot control valve is supplied with
air via a separate pressure port.
This should be connected to port X.
Bulkhead
As an option, the pressure supply of the system can be
segment by means of a bulkhead in the central P channel
between two pneumatic modules. This allows different pres-
sure levels or different media to be used in the same system.
In the case of preassembled systems, the position of a bulk-
head is marked on the corresponding pneumatic module.

COMMISSIONING, MAINTENANCE,
SERVICE, DIAGNOSIS OF ERROR
Decommissioning
DANGER!
Hazard due to high pressure!
Interference with the system will result in an acute risk of
injury.
Switch off 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 off the power supply before starting
work!
Observe all applicable accident prevention and safety
regulations for electrical equipment.
•
•
Shut down the system as follows:
Depressurise the system.
Switch off the power supply.
Dismantle the modules.
Store the modules in the original packaging.

Cleaning
Use only a damp, lint-free cloth for cleaning the system.
Solvents or alcohol are not suitable for cleaning. They may
attack the platic parts.
DANGER!
Sparking due to electrostatic discharge!
In the case of friction on plastic surfaces, sparks my be
caused by electrostatic discharges.
Use only damp cloths for cleaning the device surfaces! •
