actuator may be mounted up to 200 ft. (61 m) from the
controller; twisted pair wire is recommended for wire runs
longer than 100 ft. (30.5 m). Using Sylk-enabled actuators
saves I/O on the controller and is faster and cheaper to
install since the bus is polarity insensitive.

3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
TYPICAL SPECIFICATION
—
Spring return actuators shall be direct coupled type requiring
neither crankarm nor linkage and be capable of direct mounting
to a jackshaft of up to 5/8 in. diameter. The actuator shall connect
to the shaft using a removable output hub with a self-centering
shaft coupling. This coupling shall provide concentric mounting
and include an integral adjustable range-stop mechanism.
The actuator shall provide two-position, floating, proportional, or
Sylk bus control. Proportional control refers to direct acceptance
of 0-10 Vdc, 2-10 Vdc, or (with addition of a 500 ohm resistor) a 420 mA input signal. Proportional and floating control models shall
provide a feedback signal. Sylk-enabled models provide control
and feedback via communication between the actuator and Sylkenabled controller. Actuators shall provide wiring terminals
located within an integral access cover with conduit connections.
Proportional and floating actuators shall have a rotation direction
control switch accessible on the cover.
All spring return actuators must be designed for either clockwise
or counterclockwise fail-safe operation with a continuously
engaged mechanical spring. This spring must return the valve or
actuator to a fail-safe position within 25 seconds of power loss.
All actuators shall be designed for a minimum of 60,000 fullstroke
cycles at rated torque and temperature, 60,000 spring return
cycles and 1,500,000 repositions. Run time shall be constant and
independent of: load, temperature, and supply voltage (within
specifications). All actuators shall be UL60730 and cUL (CSA22.2)
listed, have a five year warranty, and be manufactured under ISO
9001 International Quality Control Standards. Actuators shall be
as manufactured by Honeywell.
CAUTION
Motor Damage Hazard.
Corrosive vapors and acid fumes can damage
metal and plastic parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
CAUTION
Equipment Damage Hazard.
Tightly securing actuator to damper housing can
damage actuator.
Mount actuator to allow it to float along its vertical axis.
Preparation
Before mounting the actuator onto the damper shaft,
determine the:
— Damper/valve opening direction for correct spring return
rotation. The actuator can be mounted to provide clockwise
or counterclockwise spring return by flipping or turning the
unit over.
— Damper shaft size (see the Specifications section).

Using other brackets or linkages, the actuator can
be foot-mounted or tandem-mounted.
Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
Installer must be a trained, experienced service
technician.
After installation is complete, check out product
operation as provided in these instructions.
The actuators are designed to open a damper by driving the
damper shaft in either a clockwise
or
counterclockwise
direction (see Fig. 2).

These actuators are designed to mount directly to a damper
external drive shaft. The shaft coupling fastens to the drive
shaft. The actuator housing includes slots which, along with
an anti-rotation bracket, secure the actuator to the damper
frame or duct work (see Fig. 7).
NOTES:

BACK
Fig. 2. Spring Return DCA mounting orientation.
Measure Damper/Valve Shaft Length
If the shaft is less than three inches in length, the shaft
coupling must be located between the damper/valve and
actuator housing. If the shaft length is more than three inches,
the shaft coupling may be located on either side of the
actuator housing.
When mounted correctly, these slots allow the
actuator to float without rotating relative to the
damper shaft.

62-0274—09
3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
SELECT MINIMUM POSITION (MS74 SERIES)
To set the actuator minimum position, turn the AUX dial to the
desired position. Alternatively, minimum position can be set
with an externally connected 1kOhm potentiometer connected
across common (terminal 2) and minimum position (terminal
4); the setting on the AUX dial will be overridden.
If the coupling must be moved from one side of the actuator to
the other, reverse the spring return direction and flip the
actuator. Follow these instructions (see Fig. 3):
1. Remove the retainer clip from the shaft coupling and set
it aside for later use.
2. Remove shaft coupling from one side of the actuator.
3. Replace the shaft coupling on the opposite side of the
actuator aligning it based on the stroke labeling.
4. Replace the retainer clip on the shaft coupling using the
groove of the coupling.
SELECT SWITCH POSITION
For switch models, select the degree of rotation you want the
switch to activate.
Non-Standard Stroke
Mechanical Stroke Limit Reduction
For applications requiring a span less than 95 degrees, a
simple adjustment can be made. When the rotational
mounting of the shaft coupling is changed, the actuator drives
less than the full 90 degrees stroke.
The stroke is adjustable in 5 degree increments. Once
adjusted, the actuator drives until the shaft coupling reaches
the mechanical stop (part of the housing). The stop causes
the motor to discontinue driving and the shaft coupling drives
no farther. When the actuator returns, it stops at the fail-safe
position.
M27714
Fig. 3. Mounting shaft coupling to actuator opposite side.
Selecting Actuator Control Signal
Selections are made using a dial that appears on both the
front and back of the actuator (see Fig. 4).
To limit the stroke range, proceed as follows:
1. Remove the retainer clip from the shaft coupling and set
it aside for later use.
2. Remove shaft coupling from the actuator.
3. Rotate the coupling to the desired position, aligning it
based on the stroke labeling. See Fig. 5.
To select the control signal simply turn the mode selection dial
to the desired mode (as indicated on the device label) without
exceeding range indicators.
NOTE: The shaft coupling location determines the
travel span.

To mount the actuator to an external drive shaft of a damper,
proceed as follows:
1. Place actuator over damper shaft; and hold mounting
bracket in place. See Fig. 7.
2. Mark screw holes on damper housing.
3. Remove actuator and mounting bracket.

OPERATION
2.
The actuator is designed to be used in ventilating and air
conditioning installations to operate valves, dampers,
ventilation flaps and louvers. (For ratings, see the
Specifications section.) If the power fails, the actuator will
spring return to the fail safe position.
Override to full closed:
a. Disconnect the input signal (from terminal 3).
b. See Fig. 23.
ACTUATOR
24 VAC
1
When using a proportional controller, the actuator drives
toward its fully open position when the input signal increases;
the actuator drives toward the fully closed position when the
input signal decreases. The actuator stops when the input
signal reaches the desired proportional control point. This
operates in reverse when set to a 10-2(0) position.

The actuator is designed to respond to DDC

not to short cycle the actuator. Unstable damper

Mount actuator for required application (either clockwise
or counterclockwise
rotation to open
the damper or valve).
Check damper position and make sure that 24 Vdc/Vac
is present at the appropriate connections. (See Fig. 9.)
Apply control signal to the appropriate connections to
move the damper to the opposite position. The actuator
should drive the damper or valve.

Table 2.)
Set “Mode Select” dial to desired address (MS3105
series). (See Fig. 4.) This step is not necessary for the
MS3103 series. The MS3103 models are only available
with Address 11.
Apply S-BUS command via the connected Sylk-enabled
controller for actuator full open or full closed position.
