If the manual override is turned by 180°clockwise
and the mark is adjusted to A, then pushed in the
direction of an arrow (
), it will be back to the reset
condition. (passage P A)
•
If the manual override is turned by
180°counterclockwise and the mark is adjusted to
B, then pushed in the direction of an arrow (
), it will
be back to the reset condition. (passage P B)
(It is in the reset state at the time of shipment.)
Caution
The lighting positions are concentrated on one side for both single
solenoid and double (latching) type. In the double (latching) type, A
side and B side energization are indicated by two colors which match
the colors of the manual overrides.
•
A-side energization: A light (orange) illuminates.
•
B-side energization: B light (green) illuminates.
•
Equipped with a wiring error prevention (stop
diode) mechanism and a surge absorption
(ZNR/surge absorption diode) machanism.
Applicable to negative COM specification models.

In the case of double
(latching), the electromagnetic
valve channel is, A–(set):
P A, B R,
B–(reset):
P B, A R.
Different from the conventional double solenoid, the double type uses
a latching (self-holding system) solenoid.
Although the appearance is
the same as the single solenoid, it is constructed so that the movable iron
core in the solenoid is held in the ON position on A and B sides by
instantaneous energization (20 ms or more).
The usage and function is the same as the double solenoid.
<Special Cautions for Latching Solenoid>
1. Select the circuit in which ON and OFF signals are not energized
simultaneously.
2. 20 ms energization time is necessary for self-holding.
3. Avoid using the latching solenoid valves in environments where
impact or collisions with the valve might occur. Also, do not use in
places where strong magnetic fields are present.
4. Even though the armature in the solenoid of this valve is held on to
B side, ON position (Reset), verify either A side, ON position or B
side, ON position by energizing prior to use.
5.
After manual operation, the main valve will return to its original position.
Manual override on the pilot valve side can retain its switching
position after manipulation.
6. Please contact SMC for long-term energization applications.
7.
If the metal seal type goes down below the minimum operating
pressure of supply air (0.1 MPa or less), the main valve will get back
the home position. (B side ON position) Therefore, in the event of
shutting the supply air or applying the air with being A side ON position
remained, cylinder may be pulsated. In the event of manipulating the
supply air, the valve's switching position has to be set in the home
position side (B side ON position side).
Without an electric signal for the solenoid valve the manual override
is used for switching the main valve.
Push down on the manual override
button with a small screwdriver until it
stops. Release the screwdriver and
the manual override will return.
Push down completely on the manual
override button with a small screwdriver.
While down, turn clockwise 90°to lock it.
Turn it counterclockwise to release it.
If the manual override is turned by 180°clockwise and
the mark is adjusted to 1, then pushed in the
direction of an arrow (), it will be locked in the ON
state. If the manual override is turned by 180°
counterclockwise and mark is adjusted to 0, locking
will be released and the manual override will return.
Push down completely on the
manual override button with a
small screwdriver. While down,
turn clockwise 90°to lock it.
Turn it counterclockwise to
release it.
In the case of a double (latching) type, a manual override is provided not
only on the body side but to the pilot as a standard. (VQ0000: Pilot valve
only). After manual operation, the main valve of the manual on the body side
returns to the position before the manual operation, however, the pilot valve
manual override maintains the change-over position.
Do not apply excessive torque when turning the locking type manual
override. (0.1 N·m or less)

Precautions
Be sure to read before handling. For Safety Instructions and Solenoid Valve Precautions, refer to page 2-9-2.

How to Remove
1.
Loosen tie-rod bolt B. (Two to four turns)
2.
After fully loosening the tie-rod bolt, take
off bolt A upward as shown above.
3.
Slide the valves aside to make a 1
mm clearance between the valve to
be taken off and the others. As shown
above, remove the whole valve while
holding up the (a) side. (Avoid rough handing of the connector.)
Mounting
Reverse the sequence of steps above to
remount.
Tighten the tie-rod bolts with the
tightening torque at the right table while
using caution not to tighten the only one
side unevenly.
