AV-EP for single pressure control
Single pressure controls can be positioned at any point between the AES bus
coupler (37) and end plate (43).
If you pressurize or exhaust more than six valves at once, e.g. one single pressure
control and six directional valves, observe the following:
O With a pneumatic supply plate (39), make sure that an additional supply
or exhaust air connection is available.
O Position additional pneumatic supply plates spaced evenly in the valve system
or near valves with the highest compressed air consumptions.
O Do not place the pneumatic supply plates directly adjacent to one another.
AV-EP for pressure zone control
O Place the AV-EP pressure regulator directly adjacent to the directional
valves (42) to be supplied. The AV-EP pressure regulator is located on the side
facing the AES bus coupler (37) (see Fig. 12, pressure zone PZ).
The maximum overall flow of all actuated directional valves is limited by the
maximum nominal flow of the pressure regulator. The maximum nominal flow
can be found on the pages for individual components in our online catalog
(www.aventics.com/pneumatics-catalog).
To achieve the maximum flow of the AV-EP pressure regulator, we recommend
a pneumatic supply plate (39) upstream of the pressure regulator (see example
configuration in Fig. 12).

Single pressure control and pressure zone control
in one valve system
If you use both control types in one valve system:
O Position the single pressure control (40) between the AES bus coupler (37)
and the pressure zone control (41), see example configuration in Fig. 12.
Electrical installation conditions
Valve system layout for multipole connection:
In valve systems with 25-pin D-Sub plug, the first AV-EP pressure regulator
may only be placed after the second valve, and in valve systems with 44-pin
D-Sub plug, after the fourth valve.
The rules for converting your valve system with fieldbus connection depend
on the fieldbus protocol used. You can find information on converting your
valve system in the bus coupler system descriptions on CD R412018133.
The AES series bus coupler communicates with the electrical components
of the valve system with a data length of 128 bits. An AV-EP requires 16 bits.
O Therefore, actuate a maximum of eight AV-EP regulators for fieldbus connection
with an AES series bus coupler.
You are then unable to operate further directional valves in the AV valve system.
Example: With four AV-EP regulators for fieldbus connection (64 bits), you can
additionally operate 32 directional valves (64 bits).
Number of electrical components
In an AV valve system, you can operate a maximum of 32 electrical components.
Some configured components have multiple functions and therefore count
as multiple electrical components.

13 Integrating AV-EP into
an AV Valve System
The extension of an AV multipole valve system with AV-EP pressure
regulators for multipole connection is not possible. AV multipole valve
systems can, however, be configured with AV-EP pressure regulators
for multipole connection.
Danger of injury if assembled under pressure or voltage!
Assembling when under pressure or electrical voltage can lead to injuries and
damage to the product or system components. Danger of injury from electric
shocks and sudden pressure drops.
O Make sure the relevant system part is not under pressure or voltage before
performing the following tasks:
– Assembling the product
– Removing or connecting plugs
– Disassembling the system
– Exchanging individual components
O Protect the system against being switched on.
Danger of burns caused by hot surfaces!
Touching the surfaces of the AV-EP during operation could cause burns.
The temperature on uncoated metal can exceed 64°C and on polymers
can exceed 85°C.
O Let the device cool off before working on it.
O Do not touch the device during operation.
