The positioner is attached to the control valve
using a NAMUR bracket (10).
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) for fastening.
2800 and 1400cm² with 120mm trav-
el:
− 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)rstandthenthefol-
lower plate (3) to the bracket togeth-
er 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) and toothed
lock washer directly in the yoke hole.
− For attachment to valves with rod-
type yokes, use two U-bolts (15)
around the yoke. Align the NAMUR
bracket (10) according to the em-
bossed scale so that the follower
plate (3) is shifted by half the angle
range to the NAMUR bracket (the
slot of the follower plate is centrally

3. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
on the positioner, making sure the two
seals (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 travel listed in the trav-
eltableonpage21.
Should a pin position other than position 35
with the standard M lever be required or an
L or XL lever size be required, proceed as
follows:
5. Fasten the follower pin (2) in the as-
signed lever hole (pin position as speci-
edinthetraveltable).Onlyusethelon-
ger follower pin (2) included in the
mounting kit.
6. Place the lever (1) on the shaft of the po-
sitioner and fasten it 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.
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 its two fastening screws.
