INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
HANDLING & STORAGE
HANDLING
Proper care in handling the valve should be taken to
prevent damage. Do not drop or throw it.
STORAGE
Store the valve in the protected area from dust,
moisture, and direct sunlight. If possible, should be
kept in the original packaging.
CHECKING
• Check the product code, power supply, and voltage
before installation.
• Make sure that the bolts are not loose.
• DIP switch be sure perform set up before a power
supply injection.
Should not change an unnecessary switch.
INSTALLATION
PRECAUTIONS
Before installing, clean pipe and valve ends.
Make sure they are free of dirt, dust and etc.
PIPING FLANGES
• GS / VR type has a flow direction. Install the valve
accordingly.
• Specify the ST option if a steam fluid. Flow direction is
restricted by ST option. (BR)
• 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.
• Tighten all bolts using crossover method to load the
joint evenly.
• Wafer type ball valve is put between two seats of
flanged-end and tightened with long bolts. (GS)
• In the TR / LR type, when the flow path is subjected to
a high pressure from arrow, it may leak slightly to the
low pressure port.
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 55 °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 more than 120 mm upward from
the actuator is required.
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.
CAUTIONS FOR MAINTENANCE (GS / L3)
Do not keep warm for maintenance of the valve gland.
GS L3
TIGHTEN THE GLAND NUTS (GS / L3)
• 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.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
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.
• Input signal circuit is non-isolated.
Do not connect DC (minus) wire to other DC (minus)
common.
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.
• Check whether the MODE change DIP SW on a
circuit board substrate is set up correctly.
• When wiring, if wiring of a signal is mistaken, it will not
operate correctly. Contact us when you use two valve
or more by one controller or indicator.
• 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.
CONTROL
INPUT SIGNAL
• Use shielded wire for signal wiring where high level
noise is generated or when the wiring distance is long.
• Control with a 1 to 5 V input signal becomes an input
resistance 250 . Provide a voltage that can safely
20mA or more than.
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.
INPUT SIGNAL AND OPERATION MODE
The input signal and operation mode are set as
follows. (Factory shipped)
Input signal 4 to 20 mA or 1 to 5 V
Operation mode Mode A
Operation SHUT by decreased signal.
OPEN by increased signal.

OSRBR208-EN

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
OPERATION
TESTING
• Make sure that power supply voltage is correct. Also
check operating position, wiring, speed and signals.
• During trial operation, check that valve movement and
output signal are correct.
CONFIRM THE OPERATING CONDITION
• Adjust fluid condition, controller setting, sensor etc. so
that stable control is achieved.
• When used in an unstable control state, the life of the
actuator and the valve will be shortened.
• The desired control state is stable at the target value.
Adjust the PID setting value of the controller when
overshooting the target value greatly, when not
converging for a long time or hunting operation. Also,
when the time delay is large, please consider the
sensor position.
DUTY CYCLE (PDX)
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 50 % 30 minutes for Duty cycle is
that 15 minutes (50 % of 30 minutes) operation is
possible. The calculated value obtained by dividing
15 minutes by the operation time is the number of
times of operation within 30 minutes.
ATTENTION
• Do not change an unnecessary dip switch.
• Keep power supplied for built-in space heater to
prevent condensation inside actuator.
• Do not touch the moving parts of actuator in
operation.
• 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
PDX / PHX PDX / PHX (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.
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 valve stem.
• Confirm the bolt tightening torque.
