INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
HANDLING & STORAGE
HANDLING
Do not drop or throw the product as it may break.
STORAGE
Store away from dust, moisture and direct sunlight.
If possible, store in the original package.
CHECKING
• Check the product code, power supply, and voltage
before installation.
• Make sure that the bolts are not loose.
INSTALLATION
PRECAUTIONS
• Flush the pipeline carefully before installing the
damper. Foreign particles, such as sand or pieces of
welding electrode, will damage the disk and seats.
• For dampers with specified flow direction (WT),
check the arrows on the product before piping.
• Damper is shipped closed. (allows quick piping.)
• Disc interference may also occur when damper is
installed in pipeline with smaller than normal inside
diameter such as thick wall pipe, or lining pipe.
Suitable corrective measurement must be taken
(taper boring the pipe or pipe liner, etc.)
PIPING FLANGES
• Gasket should be selected appropriately to suit the
fluid, pressure and temperature.
Use spring washer to prevent from decreasing
surface pressure gasket when the temperature
change happens frequently.
• Wafer type butterfly damper is put between two
seats of flanged-end and tightened with long bolts.
• Before bolts are tightened, damper should be
centered within the bolts to prevent possible disc
interference or damage by contact with the pipe or
flange.
• Tighten all bolts using crossover method to load the
joint evenly.
ENVIRONMENT
• Do not install in place where corrosive gas is present
or where vibration is heavy (0.5 G or more).
• When radiant heat causes the surface temperature
of the control unit to exceed 50°C, provide an
appropriate shielding plate.
• If there is a possibility that the fluid and drive part
freeze, please take measures to prevent freezing.
POSITIONING
Should be positioned through 90° upward from
horizontal. Provide space around the product to
allow manual operation, inspection and replacement
work.
Maintenance space for upper part of actuator.
AE (120 / 300 / 600) More than 105 mm
AE (02K / 06K) AD HD More than 120 mm
OTHER NOTES
Until the wiring is completed there must be no
condensation or flooding in the interior of the
actuator, after piping. Protective caps on the cable
gland are not waterproof.
INSULATION WORK
• For maintenance of gland packing, insulation should
be below the ground part.
• The upper part of the ground plate part is a heat
dissipation part, do not insulate it.

OSBWT225-EN

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
TIGHTEN THE GLAND NUTS
• Check that there is no leakage from the gland
packing.
• If it leakage, tighten gland nuts by alternately.
Do not over-tighten the gland nuts.

WIRING
PRECAUTIONS
• Remove the actuator cover before wiring.
• Two G1/2 electrical connections are provided with a
cable gland and plug. Usable cable size is 6 to 12
mm.
• When using a flexible tube, dew condensation may
occur inside the actuator due to respiration from the
inside of the tube and malfunction may result. Seal
the flexible tube connector part with a sealant.
• Sealants that affect the electrical contacts should not
be used inside the electric actuator.
• If long distance wiring or low voltage operation,
check that terminal voltage is in the proper range.
CONNECTION
• Do not wiring outdoors on a rainy day.
• Check the power supply and voltage.
Connect the signal as shown in the wiring diagram.
Do not connect unnecessarily terminal.
• Actuator should be electrically grounded.
Use the terminal marked ( ) inside the actuator.
PREVENT DEW CONDENSATION
• When installing the cover after wiring, perform the
bolt by the temporary tightening procedure and the
permanent tightening procedure to tightly and
securely tighten the rubber packing so that water
does not enter from the outside.
• Tighten the cable gland nut so that there is no
leakage from the wire entrance.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
CONTROL
AE1
Each control switch should be prepared one by one.
Do not operate two or more from one switch at the
same time.
AD2 / HD2 / AE2
When using control switch with current leakage
(more than 1 mA) such as TRIAC or relay with CR,
it can cause malfunction.
DC POWER SUPPLY
• Battery or full wave rectification can be used.
• Consider an inrush current of motor.
(It is 1.5 to 3 times of consumed current.)
• When using a DC voltage, be selected the wire
thickness by the wiring distance.
• Do not use power supply that require more than
1 second with rise and fall time.
USE OF OPEN/SHUT SIGNALS
Use signals within the capacity of output signal
rating.
OPERATION
TESTING
• Make sure that power supply voltage is correct. Also
check operating position, wiring, speed and signals.
• During trial operation, check that damper movement
and OPEN and SHUT signals are correct.
DUTY CYCLE
Confirm that the operation frequency is within the
specified duty cycle.
Use beyond the load time rate range will affect
product life. Also, it may cause burnout.
Duty cycle is a value that regulates the opening /
closing frequency of the actuator. The meaning of
20 % 15 minutes for Duty cycle is that 3 minutes
(20 % of 15 minutes) operation is possible.
The calculated value obtained by dividing 3
minutes by the operation time is the number of
times of operation within 15 minutes.
ATTENTION
• Keep power supplied for built-in space heater to
prevent condensation inside actuator.
• Do not touch the moving parts of actuator in
operation.
• Do not insert a reverse signal during operation.
It may shorten the life of product.
• Never put anything on the actuator or make it into a
foothold.
MANUAL OPERATION
PRECAUTIONS
• Be sure to turn off the power before manual
operation.
• Operate manually with reference to the opening
degree label. Do not turn beyond the fully open / fully
closed position. Operation failure may occur during
automatic operation.
THE WAY OF OPERATION
AD / HD HD (06K)
Manual operation can be possible by pulling down
manual clutch knob. Set the knob to manual
position and operate the joint by using an
adjustable wrench in the SHUT/OPEN direction.
When it becomes in the position besides the range
of operation in the case of manual operation, it
may stopped automatic moving.
In case the manual clutch knob is not easy to pull
down, try moving joint or manual shaft to the
opposite direction by wrench. For automatic
operation, reset the knob to automatic position.
Be sure to confirm that knob is reset completely.
AE AE (06K)
Turn manual shaft
slowly with an
adjustable wrench.
Remove the cap.
Turn manual shaft
solely with M8 hexagon
socket screw keys.
Before automatic operation, be sure to remove
wrench.
MAINTENANCE
• To prevent electric shock, be sure to turn off the
power when removing the actuator cover.
• Do the routine maintenance at least once in half a
year.
Inspection items
• Confirm operation of opening and closing.
• Confirm that an actuator is not hot excessively.
• Confirm existence of abnormal noise and
vibration during operation.
• Confirm whether screws are loose or not.
• Confirm that water or condensation no remains
in the actuator.
• Confirm the fluid temperature or pressure.
• Confirm the leak from damper stem.
• Confirm the bolt tightening torque.
