N05,N10 SERIES DAMPER ACTUATORS FOR MODULATING AND FLOATING CONTROL
After removing power or setting the function selection switch to
the "Service/Off" position, the gear train can be disengaged using
the declutch button, permitting the shaft adapter to be manually
rotated to any position. If you have wired the actuator for
feedback signal, then, after adaption, the feedback signal will
follow the new position.
Limitation of Rotation Stroke
Two adjustable mechanical end limits are provided to limit the
angle of rotation as desired (see Fig. 7). The mechanical end
limits must be securely fastened in place.
Fig 6.
Mechanical end limits
To ensure tight closing of the dampers, the shaft adapter has a
total rotation stroke of 95°.
After adjusting the mechanical end limits, the user should trigger
adaption (see section "Adaption").
INTERNAL END SWITCHES
The internal end switches "A" and "B" are changeover switches
which are activated when the shaft adapter moves past a position
of 5° and 85°, respectively (see also Table 5).

INSTALLATION
To avoid personal injury (electrical shock) and to
prevent equipment damage, before installation, you
must remove power.
These actuators are designed for single-point mounting.
Mounting Instructions
All information and steps are included in the Installation
Instructions (Product Literature No. 62-0224) supplied with each
actuator.
Mounting Position
The actuators can be mounted in any position (IP54 is dependent
upon orientation; see Fig. 9). Choose a mounting position
permitting easy access to cables and controls.
Fig 8.
NOTE: Further, in order to guarantee IP54, only original
Honeywell grommets may be used.
Anti-Rotation Bracket and Screws
If the actuator is to be mounted directly on a damper shaft, use
the anti-rotation bracket and screws included in the delivery
package. The min. distance between the center of the damper
shaft and the middle of the anti-rotation bracket is 3.35 in.; a max.
of 4.25 in. is allowed (see also Fig 14).
Depending upon the specifics of your mounting site, the actuator
may shift in position slightly while tightening the screws at the top
of the shaft adapter. The anti-rotation bracket features a T-piece
with a 5-mm-long shank to accommodate for this movement. It is
important to ensure that this play is not impeded.
Universal Shaft Adapter
The universal shaft adapter can be used for shafts of various
diameters and shapes (round: 3/8...5/8 in. and square:
1/4...1/2 in.).
