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 90 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
• 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.
• Use suitable flexible cable (5 to 10.5 mm).
Lock and seal the cable completely to prevent
condensation inside the actuator.
• Built-in terminal block can clamp up to 1.5 mm in
diameter without using solderless terminal.
• Allow proper cable slack for maintenance.
• 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
• Use shielded wire for signal wiring where high level
noise is generated or when the wiring distance is long.
• 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.
• Input signal circuit is non-isolated.
Do not connect DC (-) wire to other DC (-) common.
• Set to stabilize the MV value the PID constant of the
adjustment meter. The life of the actuator and the
valve becomes short if the movement of MV value is
used on unstable condition.
• The input signal and operation mode are set as
follows. (Factory shipped)
Input signal 4 to 20 mA
Operation mode Mode A
Operation SHUT by decreased signal
OPEN by increased signal
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.
ATTENTION
• 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.
ADJUSTABLE RANGE OF STROKE
LAX-030
• SHUT by an input signal 4 mA and shipped.
• It is not necessary to adjust the stroke.
LAX-070
• SHUT by an input signal 4 mA and shipped.
• Can be adjusted in the range of 7 to 11.5 mm.
(default stroke: 11.5 mm)
