Rotation Limitation
T
he angle of rotation limiter, which is built into the actuator, is used in conjunction with
t
he tab on the universal clam
p
or IND-AFB
p
osition indicator. In order to

T
he rotation limiter may not work in certain mounting orientations using the ZG-118
mountin

bracket. Limitin

T
he built-in rotation limiter ma
y
be used in 2 wa
y
s to control the rotational out
p
ut of
t
he AFB, AFX series actuator. One use is in the a
pp
lication where a dam
p
er has a
desi
g
ned rotation less than 90°. An example would be a 45° or 60° rotatin
g
damper.
T
he other a
pp
lication would be to set a minimum dam
p
er
p
osition which can be easil
y
set or chan
g
ed without havin
g
to remove the actuator from t
