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.

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).

control signals (switch “open” or “230 Vac”) applied to terminals 1

and 3 and the function selection switch setting: only one manner

of wiring is permitted (see Fig. 9).

MANUAL ADJUSTMENT

IMPORTANT

To prevent equipment damage, before manual

adjustment, you must remove power or set the func-

tion 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 5).

-POSITON CONTROL

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 supplied with each actuator.

Mounting Position

The actuators can be mounted in any position (IP54 is dependent

upon orientation; see Fig. 5). Choose a mounting pKosition

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 11).

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.
