6 Operating Mode

Make sure that the operating pressure lies at least 1 bar above the
maximum output pressure to be controlled. Otherwise, only a reduced output
pressure range is available.
EV03 pressure regulator with base plate
EV03 pressure regulators are always used together with a base plate. The base plate
is supplied with operating pressure from the line connected to supply connection 1
and distributes the volume flow as follows:
W
The EV03 pressure regulator takes as much supply air as necessary to control
the specified set point.
W
The controlled pressure is forwarded to the consumer connected to the base
plate via the base plate's working connection.
Response to power failure
The response to a power failure depends on how the EV03 pressure regulator was
configured on delivery. In the event of a power failure, the device either exhausts the
operating line or briefly maintains the output pressure, depending on the
configuration.
O Refer to the section "Product identification" in chapter 5 for information on how
your device responds to a power failure.

7 Assembly
Hazardous movements due to incorrect fastening!
Other system parts may be damaged by uncontrolled device movements.
O Make sure that the device is securely fastened.
O Always mount the base plate of the EV03 pressure regulator
– with screws in the through holes or
– with mounting kits to a rail or a mounting plate (see online catalog at
www.aventics.com/pneumatics-catalog)..
You can assemble the EV03 pressure regulator in four different ways:
1. To a mounting plate using screws in the upper through holes,
2. To a mounting plate using screws in the through holes on the side,
3. Using the mounting kit for assembly on a mounting plate (R414002582),
4. Using the rail mounting kit for TH35-7.5 rails (R414002583).
Before assembly
O Make sure the relevant system part is not under voltage or pressure.
O Let the EV03 pressure regulator acclimate itself for several hours before
installation, otherwise water may condense in the housing.
O See the dimensioned drawing for the hole spacing (see Fig. 4).
