1) Manual operating device
As this is a pilot solenoid valve, the spool will not be switched by operating
the manual operating device without an air supply to the P port.
2) Non-lock type manual operating device
Push in the manual axis all the way. With the 3-position single solenoid, the
valve is energized while the axis is being pressed and it returns to the origi-
nal state when released. With the 2-position double solenoid, however, the A
(B) side is energized when the manual axis on that side is pushed in ; the
spool retains the situation even when the axis is released. To return to the
original state, push the manual axis on the B (A) side.
3) Lock type manual operating device
Turn it 90 degrees (clockwise only) with your finger or a screwdriver, and the
valve is energized and locked. Do not turn it further after the valved is
locked to prevent damage to the device.
Be sure to unlock it before the regular operation.
a) After using the manual operating device, be sure to
reset the manual operating device to the original
(OFF) position before resuming the operation of the
device.
After a non-lock type operation (push and release), be
sure to check that the manual operating device is au-
tomatically reset. After a lock-type operation (push
and lock), be sure to release the lock to turn the
manual operating device OFF.
b) Before using the manual operating device, make sure
that nobody is present near the cylinder to be acti-
vated.
