Design and principle of operation
− Attachment to rotary actuators accord-
ing to VDI/VDE3845:
The positioner is mounted to the rotary
actuator using the corresponding acces-
sories.

3.3 Volume restriction
The volume restriction Q serves to adapt the
air output capacity to the size of the actua-
tor.
The volume restriction is a screw restriction
(Table1onpage18)whichisscrewedin-
to the signal pressure output of the positioner
(or output of the pressure gauge bracket or
connecting plate).
