GENERAL
Excellent performance actuator for electric shut-off valves equipped with
connector for damper shaft and bracket.
It has a new structure with ultra high capacity electric double layer capacitor.
In case of power failure, capacitor discharges electricity and operates valve.
This series can handle high frequency (over 200,000 times) operation.
When motor is not in motion, consumed electric power is less than 3W,
and it is energy-saving design.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
HANDLING & STORAGE
HANDLING
Proper care in handling the actuator should be taken
to prevent damage. Do not drop or throw it.
STORAGE
Store the actuator in the protected area from dust,
moisture, and direct sunlight. If possible, actuator
should be kept in the original packaging.
CHECKING
Check the product code, power supply, and voltage
before installation.
INSTALLATION
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 more than 105 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.
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.
CONTROL
• When using control switch with current leakage
(more than 1 mA) such as TRIAC or relay with CR,
it can cause malfunction.
• 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 valve 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.
CAUTION
Since this actuator is designed for electric shut off,
even the power is turned off it may still operate for
about 30 minutes after power shuts off. Please follow
instructions when adjusting opening angle of the
valve or replacing parts.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
MANUAL OPERATION
PRECAUTIONS
• Manual operation should be a temporary operation.
• Be sure to turn off the power before manual operation.
• Actuator may operate for 15 minutes after power
shuts off for ECR-120, and 30 minutes for ECR-360.
When manual operation is required, follow steps
below.
1) Turn manual shaft slowly with a
smooth-jawed wrench.
2) When limit switch leaves from SW setting
cam, actuator's motor starts.
Keep it in that position.
3) In about 30 seconds, motor protect circuit
starts and the motor stops.
Go ahead and operate manually.
THE WAY OF OPERATION
Turn manual shaft slowly with an adjustable wrench.
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.
• Turn off the power and check if the valve
operates normally with built-in capacitor.
