MN6105VAV 5 NM VAV ACTUATOR
suitable for mounting onto a 3/8 to 1/2 in. (10 to 13 mm)
square or round VAV box damper shaft. The minimum VAV
box damper shaft length is
1-9/16 in. (40 mm).
The two mechanical end-limit set screws control the
amount of rotation from 12° to 95°. These set screws must
be securely fastened in place. To ensure tight closing of
the damper, the shaft adapter has a total rotation stroke of
95° (see Fig. 1).
The actuator is shipped with the mechanical
end-limit set screws set to 95 degrees of rota-
tion. Adjust the two set screws closer together
to reduce the rotation travel. Each "hash mark"
indicator on the bracket represents approxi-
mately 6.5° of rotation per side.
The declutch button, when pressed, allows you
to rotate the universal shaft adapter (see Fig.
Determine the damper rotation and opening angle
prior to installation. See Fig. 2.
