Danger caused by escaping compressed air!
Device is operating under pressure. If the additional inlet connection (23) on the base plate is
opened, the blanking screw may be forced out by the compressed air and cause injuries or
damage.
Never open the blanking screw during operation.
Only connect an additional supply pressure connection in a pressure-free state.

Controlling the ED12

You can continually adjust the pressure once you have connected
the electrical and pneumatic supply on the ED12. To do this, the
ED12 is e.g. controlled via a controller or potentiometer using a set
point. The electronics compare the set point with the outlet
pressure, which is measured by a pressure sensor, and generate
a control variable that is used to control the 3/3-way valve with U/
I converters and a proportional magnet. This sets the stipulated
pressure.
