Installation
a) Heavy-duty version
Î See Fig.5-22
Î Required mounting parts and accesso-
ries: Table 5-10
Both mounting kits contain all the necessary
mounting parts. The parts for the actuator
size used must be selected from the mount-
ing kit.
Prepare actuator and mount possibly re-
quired adapter supplied by the actuator
manufacturer.
1. Mount the housing (10) onto the rotary
actuator.IncaseofVDI/VDEattachment,
place spacers (11) underneath, if neces-
sary.
2. For SAMSON Type3278 and VETEC
S160 Rotary Actuators, fasten the
adapter (5) onto the free end of the shaft
and for VETECR Actuator, place on the
adapter (5.1). For Type3278,
VETECS160 and VETECR Actuators,
place on the adapter (3). For Type3278,
VETECS160 and VETECR Actuators,
placeontheadapter(3).ForVDI/VDE
version, this step depends on the
actuator size.
3. Stick adhesive label (4.3) onto the cou-
pling in such a manner that the yellow
part of the sticker is visible in the window
of the housing when the valve is OPEN.
Adhesive labels with explanatory sym-
bols are enclosed and can be stuck on
the housing, if required.
4. Fasten coupling wheel (4) on the slotted
actuator shaft or adapter (3) using screw
(4.1) and disk spring (4.2).
5. Unscrew the standard follower pin (2)
from the positioner's M lever (1). Attach
thefollowerpin(Ø5mm)includedinthe
mountingkittopinposition90°.Proceed
asdescribedinsection5.3.
6. Mount connecting plate (6) for required
G¼connectingthreadorpressure
gauge bracket (7) with pressure gauges
on the positioner. Make sure that the two
seals (6.1) are seated properly. Dou-
ble-acting springless rotary actuators re-
quiretheuseofareversingamplieron
the connection side of the positioner
housing(seesection5.5.7).
7. For actuators with a volume of less than
300cm³,screwthescrewrestriction(or-
der no. 1400-6964) into the signal pres-
sure output of the positioner (or the out-
put of the pressure gauge bracket or con-
necting plate).

Attachment according to VDI/VDE 3845
(September 2010), xing level 1, AA1 to

operation')
Use a screw restriction in the signal
pressure output for actuators with
<300cm³volume
