Contents of Package
The delivery package includes the actuator, parts 1 through 6
(see Fig. 1), plus two cable grommets and a spare cable
grommet.
RUN MODES
The function selection switch (see Fig. 2) can be used to place
the actuator into any one of two different modes:
? Service/Off; or
? the floating/2-position run mode (“Dir” for CCW-closing
dampers or “Rev” for CW-closing dampers).
Fig. 2. Function selection switch
Power-Off Behavior
If power is removed, the shaft adapter remains in position.
Service/Off
If the function selection switch is set to the “Service/Off” position,
then all rotary movement is cancelled, and all control signals are
ignored, thus allowing the actuator to be manually operated
safely.

N05,N10 SERIES DAMPER ACTUATORS FOR FLOATING/2-POSITON CONTROL
Floating/2-Position Run Mode
If the function selection switch has been set to one of the two floating/2-position control settings—and if the actuator is wired correspondingly (see Fig. 7, Fig. 8, and Fig. 9)—then as soon as
operating power is applied, the shaft adapter will run according to the control signals applied.
Table 1 describes the behavior (“stops,” rotates “CCW,” or rotates “CW”) of the CN6105/CN6110 in dependence upon the control signals (switch “open” or “24 Vac/dc”) applied to terminals 3 and 4, the function selection switch setting, and the manner in which the actuator is wired (either for floating mode: see Fig. 7; or for 2-position mode: see Fig. 8).

MANUAL ADJUSTMENT
IMPORTANT
To prevent equipment damage, before manual
adjustment, you must remove power or set the function
selection switch to the “Service/Off” position.
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. Limitation of Rotation Stroke
Two adjustable mechanical end limits are provided to limit the angle of rotation as desired (see Fig. 3). The mechanical end limits must be securely fastened in place.
Fig.3. Mechanical end limits
To ensure tight closing of the dampers, the shaft adapter has a total rotation stroke of 95°.
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 3).

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. 8). Choose a mounting position permitting easy access to cables and controls.
Fig. 5. Mounting for IP54
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 10).
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.).
WIRING
To avoid personal injury (electrical shock) and to
prevent equipment damage, before wiring, you must
remove power.
Access Cover
IMPORTANT
Once the access cover has been removed, please take
care to avoid damaging any of the parts now accessible. The access cover can be unscrewed and removed in order to gain access to the terminal block(s) and perform wiring.
