4.4 Attachment to rotary

actuators

Refer to Table 4 on page 33 for the required

mounting parts and accessories.

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 explana

-

tory 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), mak

-

ing sure both seal rings (6.1) are

seated properly.

For double-acting, springless rotary ac

-

tuators, a reversing amplifier is re

-

quired to attach the positioner to the

actuator. Refer to section 4.5.

7. For actuators with a volume of less than

300 cm³, screw the screw restriction

(accessories order no.1400-6964/item

no. 0390-1424) into the signal pres

-

sure output of the positioner (or the out-

put of the pressure gauge bracket or

connecting plate).

8. Place positioner on housing (10) and

screw it tight. Considering the actua-

tor's direction of rotation, align lever

(1) so that it engages in the correct slot

of the coupling wheel with its follower

pin (Fig. 8).
