5.3 AV-EP base plate versions
AV-EP base plates are available in different versions. You can use the AV-EP pres-
sure regulator for pressure zone control or single pressure control depending on
the selected base plate.
• In AV-EP base plates for pressure zone control, all pneumatic connections are
run through the base plate.
• On AV-EP base plates for single pressure control, the outlet connection is on
the front side.
AV-EP base plates for fieldbus connection and AV-EP base plates for multipole
connection have different circuit boards. Each AV-EP pressure regulator therefore
requires an AV-EP base plate that corresponds to the control.

5.4 AV-EP pressure regulator connections
5.4.1 Electrical connections – AV-EP for fieldbus connection
Power supply
The AES bus coupler supplies the AV-EP pressure regulator with the valve voltage
(UA) and electronics voltage (UL) via the circuit board in the base plate.
Functional earth connection
The AV-EP pressure regulator grounding is implemented via the circuit board in
the base plate. Thus, the device does not have to be additionally connected to
functional earth.
Fieldbus connection
The AES bus coupler controls the AV-EP pressure regulator via the circuit board in
the base plate.
5.4.2 Electrical connections – AV-EP for multipole connection
AV-EP pressure regulators for multipole connection are actuated via a 5-pin, A-
coded M12 connection and work independently from the multipole valve system
as a standalone device. Within the multipole valve system, they forward the sig-
nals to the next component via the circuit board. The signals are only forwarded,
and not changed.

1. Only use tested plugs and cables.
2. Always use a shielded line to connect the integrated M12 plug.
3. Always connect the line shield (FE/pin 5) to both the housing of the integrated
M12 plug and the system.
4. Make sure that the 24 V DC power supply for the valves is present in the de-
vice.
5. Connect the signal line on the M12 plug of the AV-EP pressure regulator for
multipole connection.
The tightening torque for the socket is 1.5 Nm +0.5.
