Required mounting parts and accesso -
ries:
section 3.3 on page 15.
1. Place follower clamp (2) on the slotted
actuator shaft or spacer.
2. Place coupling wheel (3) with flat side
facing the actuator on the follower clamp
(2). Align slot so that it matches the di-
rection of rotation when the valve is in its
closed position.
3. Fasten the coupling wheel and follower
clamp tightly onto the actuator shaft us-
ing screw and disk spring.
4. Fasten the bottom pair of brackets (4)
with the bends pointing either facing to
the inside (80 mm) or to the outside
(130 mm) (depending on the actuator
size). Position the top pair of brackets (5)
and fasten.
5. Unscrew the standard follower pin from
the limit switch's M lever (1). Use the
metal follower pin (Ø 5 mm) included in
the mounting kit and screw tight into the
hole for pin position 90°.
6. Fasten the limit switch onto the mounting
plate (6).
7. Place the limit switch together with the
mounting plate on the top bracket (5)
and screw it tight. Taking the actuator's
direction of rotation into account, adjust
lever (1) so that it engages in the slot of
the coupling wheel (3) with its follower
pin.
Î
Make sure that the lever (1) is parallel to
the long side of the limit switch when the
rotary actuator is at half its angle of ro-
tation.
8. Stick the scale plate on the coupling
wheel so that the arrow tip indicates the
closed position and it can be easily read
when the valve is installed.
