Manual Override Switch Operation
For manual override operation, move the manual override switch to a
position where letters A and B can be seen. [Manual override switch
release status (refer to the figure below)] Operation with the manual
override switch in a locked status can cause damage to the manual
override and air leakage, so be sure to release the manual override
switch before use. After manual override operation, lock the manual
switch for use (when the manual override of the push-turn locking
slotted type is locked, a manual override switch cannot be locked).
Manual Override Operation
When the manual override is operated, connected equipment will
be actuated. Confirm safety before operating.
￭
Non-locking push type
Press in the direction of the arrow.
￭
Push-turn locking slotted type
While pressing, turn in the direction of the arrow (90
o
clockwise).
When you operate the D type with a screwdriver, turn it gently
using a watchmaker’s screwdriver. [Torque: under 0.05 N
･
m]
When you lock the manual override of the D type, be sure to push
it before turning. [Load: 10 N or less] Turning without pushing can
cause damage to the manual override and trouble such as air
leakage, etc.
Valve with Switch
When turning off the valve using the switch, move it to the position
where the valve is locked. If the switch is at an improper position
and is energized, equipment connected to the valve could be
actuated.
Also, if the switch is turned OFF on the valve in the energized
state, be careful because any actuators connected to a single
solenoid, a dual 3 port valve or a 3 position valve will actuate.
Electric circuit diagram
(with positive common and light/surge voltage suppressor)
Please connect it together with the polarity of the electric wiring of
the manifold.
Valves with built-in back pressure check valve is to protect the
back pressure inside a valve. For this reason, use caution the
valves with external
pilot specification cannot be pressurized
from exhaust port [3/5 (E)].
As compared with the types which do not integrate the back
pressure check valve, C value of the flow characteristics goes
down. For details, please contact SMC.
Exhaust Restriction
Since the SJ series is a type in which the pilot valve exhaust joins
the main valve exhaust inside the valve, use caution, so that the
piping from the exhaust port is not restricted.
