AV-EP pressure regulator connections
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.
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 signals
to the next component via the circuit board. The signals are only forwarded,
and not changed.

6 Operating Mode

AV-EP pressure regulators are always used together with an AV-EP base plate that
represents the interface between the valve system and the AV-EP pressure regulator.
Pressure regulators in combination with switching valves
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 components:
W
Do not exceed the maximum operating pressure of 8 bar in AV valve systems
with an internal pilot air supply for the switching valves.
W
Do not exceed the maximum operating pressure of 10 bar with an external
pilot air supply.
If you still want to operate the pressure regulator at the maximum operating
pressure of 11 bar, you must note the following:
W
The pilot air supply for the switching valves must be external.
W
Position the supply plate that blocks supply air channel 1 directly in front
of the pressure regulator.
W
For individual pressure regulators, position an additional supply plate between
the pressure regulator and the downstream switching valves to block supply
air channel 1.
W
If using several individual pressure regulators in a row, one supply plate
positioned upstream of the adjacent switching valves is enough.
Make sure that the operating pressure lies at least 1 bar above the
maximum output pressure to be controlled. Otherwise, only a reduced
operating pressure range will be available.
Pressure zone control
All pneumatic connections are located in the AV-EP base plate.
The AV-EP base plate receives the operating pressure from the pneumatic supply
plate (32) on the left side. The base plate forwards the operating pressure to the
AV-EP pressure regulator. The regulator adjusts the pressure to the specified set
point and forwards it to the components to the right via the base plate. The pressure
of the pressure zone control is applied up to the end plate or the next supply plate
that blocks supply air channel 1. The exhaust travels through the collector channel
to the next pneumatic supply plate.
AV-EP pressure zone control in the AV05 valve system
If you use a pressure zone control in the AV05 vale system, we recommend external
pilot air, since the air for the pilot is taken from the last pressure zone. As a result,
the pressure of the pilot air corresponds to the pressure controlled by the AV-EP
pressure regulator. In individual cases, the valves may experience malfunctions.
