2.2 Attachment according to
IEC 60534-6
The positioner is attached to the control
valve with a NAMUR bracket (10).
Refer to Table 3 on page 18 for the required
mounting parts as well as the accessories
with their order numbers.
Note the travel table on page 15.
1. Screw the two bolts (14) to the bracket
(9.1) of the stem connector (9), place the
follower plate (3) on top and use the
screws (14.1) to tighten.
Actuator sizes 1400 cm² and 2800 cm²
(120 mm travel):
For a travel of 60 mm or smaller, screw the
longer follower plate (3.1) directly to the
stem connector (9). For a travel exceeding
60 mm, mount the bracket (16) first and
then the follower plate (3) to the bracket to-
gether with the bolts (14) and screws (14.1).
2. Mount NAMUR bracket (10) to the con-
trol valve as follows:
For attachment to the NAMUR rib, use
an M8 screw (11), washer, and toothed
lock washer directly in the yoke bore.
For attachment to valves with rod-type
yokes, use two U-bolts (15) around the
yoke.
Align the NAMUR bracket (10) in such a
way that the slot of the follower plate (3)
is centrally aligned with the NAMUR
bracket at mid valve travel.
3. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
(8) on the positioner, making sure both
seal rings (6.1) are seated properly.
4. Select required lever size (1)
M
,
L
or
XL
and pin position according to the actua-
tor size and valve travels listed in the ta-
ble on page 15.
Should you require a pin position other
than position
35 with the standard in-
stalled lever M , or require a lever size L
or XL , proceed as follows:
5. Screw the follower pin (2) in the as-
signed lever bore (pin position) as listed
in the table. Only use the longer follower
pin (2) included in the mounting kit.
6. Place lever (1) on the positioner shaft
and screw tight using the disk spring
(1.2) and nut (1.1).
Note: If you have mounted a new lever (1),
you must move it once all the way as far as
it will go in both directions.
7. Place positioner on the NAMUR bracket
in such a manner that the follower pin
(2) rests in the slot of the follower plate
(3, 3.1). Adjust the lever (1) correspond-
ingly.
Screw the positioner to the NAMUR
bracket using both its fixing screws.
