Caution
・ The description of the sub plate and piping port do not match. Be careful with the piping port.
・ For external pilot type, pulse air is only generated while pilot air is supplied. The blow is
constantly stopped by the return spring when the pilot air is not supplied. Air may leak from
the main valve as this is metal seal type. (Refer to Fig.4)
・ When the minimum operating pressure or more is supplied to the X port, air pulse is
generated even when IN port is pressure is less than the minimum operating pressure (Refer
to Fig.4).
・ When the IN port pressure constantly exceeds the minimum operating pressure, the same air
can be connected to the IN port and X port (Refer to Fig.5).
・ When the product is used in a condition where the OUT port back pressure varies, for
example, vacuum ejector and / or suction filter is connected to the OUT port, please consider
that the operation frequency will be changed.
・ Keep using the plug and port with silencer.
・ Direct manual override is operated by flat blade screwdriver. Insert the flat blade driver to the
groove until it contacts the bottom of the groove and turn the driver 90 degrees. Rotating
direction does not matter. Do the same for release (push and rotate for 90 degrees).
・ Tighten the piping using the correct torque shown below.
・ Use an External pilot pressure higher than IN port pressure.
