TYPICAL SPECIFICATION

Spring return actuators shall be direct coupled type requir-
ing neither crankarm nor linkage and be capable of direct
mounting to a jackshaft of up to 3/4 in. diameter. The actua-
tor 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 floating and proportional control.
Proportional control refers to direct acceptance of 0-10
VDC, 2-10 VDC, or (with addition of a 500 ohm resistor) a 4-
20 mA input signal. Some proportional and floating control
models shall provide a feedback signal. 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 Interna-
tional Quality Control Standards. Actuators shall be as
manufactured by Honeywell.
Sylk™ Bus:
Sylk is a two-wire, polarity insensitive bus that provides commu-
nications between a Sylk-enabled actuator and a Sylk-
enabled controller. For wiring, the Sylk-enabled actuator may
be mounted up to 200 ft. (61m) from the controller; twisted
pair wire is recommended for wire runs longer than 100 ft.
(30.5m). Using Sylk-enabled actuators saves I/O on the con-
troller and is faster and cheaper to install since the bus is
polarity insensitive.
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.

CAUTION
Electrical Shock or Equipment Damage Hazard.
Low voltage can shock individuals or short
equipment circuitry.
Disconnect power supply before installation.
IMPORTANT
All wiring must comply with applicable codes,
ordinances and regulations.
Location
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. 10).
NOTES:
— When mounted correctly, these slots allow the
actuator to float without rotating relative to the
damper shaft.
— Using other brackets or linkages, the actuator
can be foot-mounted or tandem-mounted.
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).
Determine Appropriate Mounting
Orientation
The actuators are designed to open a damper by driving
the damper shaft in either a clockwise
counterclockwise
NOTES:
— Actuators are shipped in the fully closed
(spring return) position.
— The groove on the adapter points to a location
on the label to indicate the hub rotary position.
