Installation
5. Mount connecting plate (6) 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 amplifier on
the connection side of the positioner hous-
ing (see section 5.6.7).
6. Unscrew the standard follower pin (2)
from the positioner'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° .
7. Place positioner on the top bracket (10)
and fasten tight. Taking the actuator's di-
rection of rotation into account, adjust le-
ver (1) so that it engages in the slot of the
coupling wheel (4) with its follower pin
(Fig. 5-23). It must be guaranteed that the
lever (1) is parallel to the long side of the
positioner when the actuator is at half its
angle of rotation.
