7. Insert screws (13.1) through the middle
holes of the adapter block (13).
8. Place the connecting plate (12) together
with the seal (12.1) onto the screws
(13.1) corresponding to the fail-safe ac-
tion "actuator stem extends" or "actuator
stem retracts".
The fail-safe action that applies is deter-
mined by aligning the groove of the
adapter block (13) with the groove of
the connecting plate (12) (Fig. 8).
9. Mount the adapter block (13) together
with the connecting plate (12) to the ac-
tuator using the screws (13.1).
10. Insert the vent plug (11.1) to the Exh.
connection.
11. For fail-safe action "actuator stem ex-
tends", seal the Y1 port with a blanking
plug.
For fail-safe action "actuator stem re-
tracts", connect the Y1 port to the signal
pressure connection of the actuator.
12. Place the positioner on the adapter block
(13) in such a manner that the follower
pin (2) rests on the top of the follower
clamp (3). Adjust the lever (1) corre-
spondingly and open the positioner
cover to hold the positioner shaft in posi-
tion at the cap or the switch (Fig. 23).
The lever (1) must rest on the follower
clamp with spring force.
Fasten the positioner to the adapter
block (13) using the two fixing screws
(6.3). Make sure the formed seal (6.2) is
properly seated.
13. Mount cover (11) on the other side.
Make sure that the vent plug points
downwards when the control valve is in-
stalled to allow any condensed water
that collects to drain off.
