Installation
7. Mountthedummyplate(18)totheturn-
boardusingthescrews(18.1).Make
sure that the seals are correctly seated.
A solenoid valve can also be mounted in
place of the dummy plate (18). The orienta-
tion of the turnboard (17) determines the
mounting position of the solenoid valve. Al-
ternatively, a restrictor plate can be mounted
(uAB11).
8. Fasten the adapter block (13) to the
NAMUR connection block using the
screws (13.1).
9. Insert the vent plug into the Exh. connec-
tion.
10. Place the positioner on the adapter block
(13) in such a manner that the follower
pin (2) rests on the top of the follower
plate (3, 3.1). Adjust the lever (1) corre-
spondingly.
Fasten the positioner to the adapter block
(13) using the two fastening screws (6.3).
Make sure the molded seal (6.2) is prop-
erly seated.
11. For single-acting actuators without air
purging, connect the Y1 port of the
adapter block to the signal pressure con-
nection of the actuator. Seal the Y2 port
with a blanking plug.
For double-acting actuators and actua-
tors with air purging, connect the Y2
port of the adapter block to the signal
pressure connection of the second actua-
tor chamber or spring chamber of the
actuator.
