4.5.1 Heavy-duty version
Refer to Table 4 on page 31 for the required
mounting parts as well as the accessories
with their order numbers.
Both mounting kits contain all the necessary
mounting parts. First select correct actuator
size. Prepare actuator, and mount required
adapter supplied by the actuator manufac-
turer, if necessary.
1. Mount the housing (10) onto the rotary
actuator. In case of VDI/VDE attach-
ment, place spacers (11) underneath, if
necessary.
2.
For SAMSON Type 3278 and VETEC
S160 Rotary Actuator
, screw the adapter
(5) onto the free end of the shaft or
place adapter (5.1) onto the shaft of the
VETEC R Actuator.
Place adapter (3) onto Type 3278, VETEC
S160 and VETEC R Actuator . For
VDI/VDE version , this step depends on
the actuator size.
3. Stick adhesive label (4.3) onto the cou-
pling wheel 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
symbols are enclosed and can be stuck
on the housing, if required.
4. Screw tight coupling wheel (4) onto the
slotted actuator shaft or adapter (3) us-
ing screw (4.1) and disk spring (4.2).
5. Undo the standard follower pin (2) on
the lever M (1) of the positioner. Attach
the follower pin (Ø 5) included in the
mounting kit to pin position 90°.
6. If applicable, mount pressure gauge
bracket (7) with pressure gauges or, in
case G ¼ threaded connections are re-
quired, the connecting plate (6), making
sure both seal rings (6.1) are seated
properly.
For double-acting, springless rotary ac-
tuators, a reversing amplifier is required
to attach the positioner to the actuator.
Refer to section 4.6.
7. For actuators with a volume of less than
300 cm³, fit the restriction (order
no.1400-6964) into the signal pressure
output of the positioner (or the output of
the pressure gauge bracket or connect-
ing plate).
8. Place positioner on housing (10) and
screw it tight. Considering the actuator's
direction of rotation, align lever (1) so
that it engages in the correct slot of the
coupling wheel with its follower pin (Fig.
10).
