Observe travel tables on page 5-4.
The positioner is attached to the valve yoke
using a bracket.
1. Seal the signal pressure output at the
back of the positioner with the screw
plug (4, order no. 0180-1254) and the
associated O-ring (order no. 0520-
0412) if the screw plug is not yet in
place.
2. Fasten the bracket (9.1) to the stem con-
nector.
3. Screw the two bolts (9.2) to the bracket
(9.1) of the stem connector (9), place the
follower plate (3) on top and use the
screws (9.3) for fastening.
4. Mount the travel indication scale (acces-
sories) to the outer side of the yoke using
the hex screws (12.1), ensuring that the
scale is aligned with the stem connector.
5. Fasten the hex bar (11) onto the outer
side of yoke by screwing the M8 screws
(11.1) directly into the holes on the yoke.
6. Fasten the bracket (10) to the hex bar
(11) using the hex screw (10.1), shim
and tooth lock washer.
7. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
on the positioner. Make sure that the two
seals (6.1) are seated properly.
8. Unscrew the standard M lever (1) includ-
ing follower pin (2) from the positioner
shaft.
9. Take the S lever (1) and screw the follow-
er pin (2) in the hole for pin position 17.
10. Place the S lever on the positioner shaft
and screw tight using the disk spring
(1.2) and nut (1.1).
Move lever once all the way as far as it
will go in both directions.
11. Place positioner on the bracket (10) in
such a manner that the follower pin
slides into the groove of the follower pin
(3). Adjust the lever (1) correspondingly.
Screw the positioner to the bracket (10)
using both its screws.
5.6.4 Attachment according to
VDI/VDE 3847-1
Î
See Fig. 5-12.
This type of attachment allows the positioner
to be replaced quickly while the process is
running by blocking the air in the actuator.
The signal pressure can be blocked in the ac-
tuator by unscrewing the red retaining screw
(20) and turning the air blocker (19) on the
bottom of the adapter block.
