The product characteristics are confined to no flow in the pipeline. When air is consumed on
the output side, pressure may become unstable.
In order to avoid the error caused by noise, please take the following measures:
Set the line filter on AC power line to remove the power noise.
Keep the product away from the engine and power line to avoid noise affects.
Induced charge (like solenoid valve, relay), must prevent them from negative charge.
In order to avoid the effects of power fluctuation, please cut off the power before plug
the connector.
The cable plug is four-core wire. When the monitor output is not being used, prevent it from
touching the other wires as this can cause a malfunction.
Please note that the right angled cable connector does not rotate and is limited to only one
entry direction.
Use clean compressed air that does not contain corrosive gas. Poor air quality adversely
affects function and life.
Do not use a lubricator on the supply side of this product, the lubricated air might cause
malfunction. When lubrication of terminal equipment is necessary, connect a lubricator on the
output side of the equipment and set a check valve. When the secondary pressure is lowered
with an input signal, etc., the secondary air passes through the product and is discharged
from the EXH port. Contamination on the secondary piping and the inside of the load will
have an adverse effect on performance, etc. Keep the inside of the piping as clean as possible.
When supplying compressed air for the first time after connecting pipes, confirm that no air is
leaking from any pipe connections.
Tighten pipes with the appropriate torque to prevent air leakage and screw damage. First
tighten the screw by hand to prevent damage to screw threads, then use a tool.
For the pneumatic source, use cleaned air from which the solid, water and oil contents were
eliminated sufficiently, using an air dryer, filter and oil mist filter. Recommend selecting a
filtration precision of 5µm or less.
Please confirm the product specification and read wiring method carefully before wiring.
The color of connector pins and cable conductors must be checked when wiring. Check
wire color with handling precaution, since improper wire connection leads to destruction/-
failure and malfunction.
Do not use power voltage exceeding specifications. The product could malfunction or
catch fire if voltage exceeding the working range is applied.
Short-circuiting the load could result in rupture or fire.
The connection between the cable plug and the wire is weak. Excessive bending may
shorten the life of the plug set, causing breakage or damage.
Connect the cable to the connector on the body with arranged as shown next page.
