90°.
6. Mount connecting plate (6) for required
G ¼ connecting thread or pressure
gauge bracket (7) with pressure gauges
on the positioner, making sure the two
seals (6.1) are seated properly. Double-
acting springless rotary actuators require
the use of a reversing amplifier on the
connection side of the positioner housing
(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 out-
put of the positioner (or the output of the
pressure gauge bracket or connecting
plate).
8. Place positioner on housing (10) and
screw it tight. Taking the actuator's direc-
tion of rotation into account, adjust lever
(1) so that it engages in the correct slot
with its follower pin (Fig. 12).
