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 3/4 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 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 rota-
tion direction control switch accessible on the cover.
All spring return actuators must be designed for either clock-
wise
or
counterclockwise
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 full-
stroke cycles at rated torque and temperature, 60,000 spring
return cycles and 1,500,000 repositions. Run time shall be con-
stant 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.

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. 9).
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.
a
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).
