About This Product
The EV07 pressure regulator is a pneumatic device with integrated electronics that
is only designed to regulate pneumatic pressures. The electropneumatic pressure
regulator controls an output pressure. This pressure is given as an electrical set
point. In doing so, a pressure sensor integrated in the pressure regulator records the
outlet pressure and controls it based on the set point. As a result, the output
pressure specified by the set point is also controlled if there are disturbance
variables, such as flow changes.

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 fasten the EV07 pressure regulator in the threaded hole (10) with
screws.
Malfunction caused by closed housing ventilation port
If the housing ventilation port is closed, there is no atmospheric equalization and
the characteristics curve will change.
O Before installation, ensure that the housing ventilation port (7) is open and not,
for example, painted shut.
O Ensure that the air can circulate freely through the housing ventilation port (7).
Malfunction caused by closed exhaust opening
Exhaust air cannot be evacuated if the pilot exhaust opening is closed. Device
response to changes in the set point will be slower.
O Before installation, ensure that the exhaust opening (4) is open and not, for
example, painted shut.
O Ensure that the air can escape freely through the exhaust opening (4).
Before assembly
O Make sure the relevant system part is not under voltage or pressure.
O Let the EV07 pressure regulator acclimate itself for several hours before
installation, otherwise water may condense in the housing.
Installation conditions
Malfunction due to atmosphere containing oil
Oil may clog the housing ventilation port. This will change the characteristic curve.
O Never operate the device in an atmosphere containing oil.
Mounting orientation
O Install the device vertically in compressed air that is dry and oil-free.
Assembling on a mounting plate
Fastening with screws in the housing thread
1. Slide the cylinder head screws through the mounting plate.
2. Fasten the screws on the housing threads (10).
Connecting the pneumatics
The inside diameter of the supply line must be at least 6 mm to attain the air flow
rate stipulated in the specifications.
O Fit exhaust air connections that are not connected to an exhaust air line with a
silencer as needed.
O Ensure that enough free space is left for the pneumatic tubing so that the
permitted minimum bending radii are adhered to.
O Note that the use of PUR tubing limits the holding force of the tubing in the push-
in connectors.
O For push-in fittings, only use polymer plug accessories from the pneumatics
catalog.
O Fix the pneumatic tubing for compressed air supply near the connection to
ensure it does not bend. Rule of thumb: the first 5 cm before the inlet must be
straight.
O When using plug connectors, also note the information from ISO standard 14743
Pneumatic fluid power – Push-in connectors for thermoplastic tubes.
Connecting the supply voltage and set point
To operate the EV07 pressure regulator, you must supply the device with
compressed air, connect the 24 V DC supply voltage, and control the device with a
set point.
