Connecting the supply voltage and set point
Missing seals and plugs will lead to non-compliance with the IP65 protection
class!
Liquids and foreign objects could penetrate the device and plug connections and
destroy the electronics.
O Use IP65 protection class plug-type connections.
O Make sure that the seals are integrated in the plug and not damaged.
O Make sure that all plugs are mounted before starting the system.
To operate the ED12 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.
The actual value (-) and set point (-) are always connected to 0 V.
The following applies for all devices with 0... 10 V voltage control:
If the analog trigger signal is not electrically isolated, please heed the line
resistances to minimize set point/actual value drifting and the controlled
pressure.
Use a shielded line to connect XPC and X2M. The shield must be connected
to the plug housing.
O Please heed the following tables containing the plug assignments for the
different series.

O Make sure before connecting the plugs that all seals and caps are included and
not damaged.
O Only use pre-assembled and tested plugs and cables,
O Protect the supply voltage with an external M 2.5 A fuse.
As the 0 V lines are linked in the case of the X2M and X1S connections,
you must ensure that all the plug-type connections are correctly poled.
Short circuiting occurs due to pole confusion of the supply voltage or set
point voltage.

potentiometer.
7 Commissioning the EV12 pressure
regulator
Risk of destruction by water!
Water entering the device destroys the electronics.
O Ensure that the compensation port is sealed.
O Ensure that the four mounting screws are tightened with the correct torque.
O Never open the two fastening screws on the housing cover.
Prior to commissioning the EV12 pressure regulator
Attach base plate pneumatic connections
Depending on the application, the base plate is a
single subbase or base plate for stacking assembly.
1. Connect the supply line to inlet connection 1 on the
2. Connect the outlet line to the output connection
3. Always connect a silencer or line for restricted

Danger caused by escaping compressed air!
Device is operating under pressure. On opening the additional input connection
(36) on the base plate, the seal screw can be hurled into the surrounding area and
may cause bodily harm and material damage.
O Never undo the seal screw during operation.
O Only connect another input connection when no pressure is supplied.
Exhaust 3 (35) in the single subbase must not be sealed by a screw.
O Always mount the exhaust on an appropriate silencer (see Chapter 13
"Accessoires") or line for restricted exhaust.
Output pressure -1 bar...+1 bar:
On the ED12 pressure regulator with the pressure range -1 bar...+1 bar
a vacuum must be connected to exhaust 3.
Switching on the pneumatic and electrical supplies
Proceed as follows to commission the ED12 pressure regulator:
1. First switch on the pneumatic supply.
2. Then switch on the 24 V DC supply voltage.
Setting the set point
O Enter the desired set point in the controller or potentiometer.
O Please observe Chapter "Selecting the correct supply pressure".
8 Triggering the ED12 pressure regulator
You can continually adjust the pressure once you have connected the pneumatic and
electrical supply on the ED12 pressure regulator. To do this, the ED12 pressure
regulator is e.g. controlled via a controller or potentiometer using a set point.
The electronics compares the set point with the output pressure, which is measured
by a pressure sensor, and generates a control variable, which in turn triggers the
venting or exhaust valve via the U/I converter and proportional solenoids. This sets
the stipulated pressure.
