6.2.5 Connecting the external pilot control air (optional)
Connect the external pilot control air at connection X.
u
On the AV03, connection X is located on the left supply plate; on the
AV05, the connection is located on the right end plate!
6.2.6 Connecting the pilot exhaust air (optional)
Series AV
Connect the pilot exhaust air at connection R on the right end plate.
u
AV-BP Series
1. Make sure that connection R is always open.
2. Connect the silencer or discharge exhaust through tubing.
6.2.7 AV05: Setting the operating mode on the valve system
See Fig. 20
No subsequent changes are possible for the AV03 and AV05 series
with a fixed pilot air configuration and for the AV-BP series. The pilot
air is channeled from left to right.
The following change can only be carried out for the AV05 series with
variable pilot air configuration.
The pilot air cover in the AV05 end plate makes it possible to switch the valve sys-
tem operating mode between internal pilot control (connection 1) and external
pilot control (connection X).
1. Loosen both pilot air cover mounting screws (1).
2. Lift the pilot air cover (1).
3. Turn the pilot air cover by 180° and reinsert it (2).
4. Make sure that the seals have been inserted correctly.
5. Retighten the pilot air cover (3).
The new operating mode is now set.
Damage to the individual components or reduction in service life!
If you use pressure regulators in combination with switching valves in a valve
system, you must observe the following to avoid damaging the individual com-
ponents:
Do not exceed the maximum operating pressure of 8 bar in AV valve systems
with an internal pilot air supply for the switching valves. Do not exceed the
maximum operating pressure of 10 bar with an external pilot air supply. Do not
exceed the maximum operating pressure of 8 bar with a UL/CSA application.
If you still want to operate the pressure regulator at the maximum operating
pressure of 11 bar, you must note the following:
1. The pilot air supply for the switching valves must be external.
2. Position the supply plate that blocks supply air channel 1 directly in front of
the pressure regulator.
3. For individual pressure regulators, position an additional supply plate be-
tween the pressure regulator and the downstream switching valves to
block supply air channel 1.
4. If using several individual pressure regulators in a row, one supply plate po-
sitioned upstream of the adjacent switching valves is enough.
6.3 Connecting the electrical system
Electric shock due to incorrect power pack! Danger of injury!
1. The units are permitted to be supplied by the following voltages only:
24 V DC SELV or PELV circuits, whereby each of the DC supply circuits must
be provided with a DC-rated fuse which is capable of opening at a current of
6.67 A in 120 s or less, or
24 V DC circuits which fulfill the requirements of a limited-energy circuit ac-
cording to clause 9.4 of standard UL 61010-1, 3rd edition, or
24 V DC circuits which fulfill the requirements of limited power sources ac-
cording to clause 2.5 of standard UL 60950-1, 2nd edition, or
24 V DC circuits which fulfill the requirements of NEC Class II according to
standard UL 1310.
2. Make sure that the power supply of the power pack is always less than
300 V AC (outer cable – neutral wire).

CAUTION
CAUTION
The length of the cable (signal line) must not exceed 30 m.
6.3.1 Connection with Sub-D
• Ensure that enough free space is left for the electrical connections so that the
permissible minimum bending radii are adhered to!
• Make sure that there is adequate space for the plugs used!
Procedure:
1. Note the pin assignment scheme (R412019225) Required and supplementary
documentation!
2. Finish the cable with D-Sub mating plug and connect to the controlling elec-
tronics.
Tip: Preassembled cables with suitable D-Sub mating plugs can be found in the
online catalog at http://www.aventics.com/pneumatics-catalog.
3. Insert the D-Sub mating plug into the D-Sub connection and screw it down.
WARNING! The IP65 protection is only ensured with a correctly fitted D-Sub
mating plug (material protection, accident protection).
6.3.2 Connection with single wiring
With the AV03-SW series, the valves are connected via connection terminals on
the base plate. Within a base plate, the GND connection, e.g. 0V, is connected to
all valves.
Optionally, the ground (GND) of the base plates can be connected internally via a
GND clip. Thus only one GND connection is required for the entire valve system.
If necessary, observe the required wire cross-section. The following wire cross-
sections can be used:

6.3.3 Connection with bus coupler
See Fig. 11
When connecting with a bus coupler, please also refer to the assembly
instructions R412018134 and system descriptions (on CD
R412018133).
Make the following connections on the bus coupler:
u
• Fieldbus input X7xx (xx = fieldbus-dependent) (1), integrated M12 socket/
plug
• Fieldbus output X7xx (xx = fieldbus-dependent) (2) integrated M12 socket/
plug
• Ground connection
1. Also configure the required inputs and outputs (7) on the connected I/O mod-
ules (6).
2. Connect all FE connections of the modules with the FE of your system.
Select the cable cross section so that it is sufficient for your application.
Wrench size WS 7; tightening torque MA = 1.25 Nm +0.25.
3. Connect the power supply for your bus coupler via the integrated M12 plug
(X1S; 3; male, 4-pin, A-coded) to a suitable power source (24 V DC).
6.3.4 Connection with IO-Link
Connect your valve system with IO-Link on a master via the M12 integrated
u
plug (X7I1).
