Changing the Connector Entry Direction
To change the connector’s entry direction, set the switch on the
top of the connector block to the FREE position, before turning
the connector. Make sure to set the switch back to the LOCK
position before connecting the connector. (When the switch is
difficult to slide, move the connector a little so that it will slide
easier.)
If an excessive force is applied on the connector in the LOCK
position, the connector block may be damaged. Also, using in
such a way that the connector floats in the FREE position, it may
cause the lead wire, etc. to break. Thus, refrain from using in
these ways.
Manifold Mounting
When attaching a manifold to a mounting surface, etc., with bolts,
if the entire bottom surface of the DIN rail contacts the mounting
surface in a horizontal mounting, it can be used by simply
securing both ends of the DIN rail. However, for any other
mounting method or for side facing and rear facing, etc., secure
the DIN rail with bolts at uniform intervals using the following as a
guide: 2 to 5 stations at 2 locations, 6 to 10 stations at 3 locations,
11 to 15 stations at 4 locations, 16 to 20 stations at 5 locations, 21
to 25 stations at 6 locations, 26 to 30 stations at 7 locations and
more than 30 stations at 8 locations.
In addition, even in the case of a horizontal mounting, if the
mounting surface is subject to vibration, etc., take the same
measures indicated above. If secured at fewer than the specified
number of locations, warping or twisting may occur in the DIN rail
and manifold, causing trouble such as air leakage.
Fitting Assembly Replacement
By replacing a valve’s fitting assembly, it is possible to change the
port size of the 4(A), 2(B), 1(P), and 3/5(E) ports. When replacing
it, pull out the fitting assembly after removing the clip with a flat
heat screwdriver, etc. To mount a new fitting assembly, insert it
into place and then fully reinsert the clip.
Note 1) To change the port size of the 1(P), 3/5(E) ports into the
port sizes other than
φ
8 (straight), specify the change by
means of the manifold specification sheet.
Note 2) Be careful to avoid damage or contamination to the O-rigs,
as this can cause air leakage.
Note 3) When removing a straight-type fitting assembly from a
valve, after removing the clip, attach tubing or a plug
(KJP-02, KQ2P-
⃞⃞) to the one-touch fitting, and pull it
out while holding the tubing or plug. If it is pulled out
while holding the release button of the fitting assembly
(resin part), the release button may be damaged.
Note 4) Be sure to turn off the power and stop the supply of air
before disassembly. Furthermore, since air may remain
inside the actuator, piping and manifold, confirm that the
air is completely exhausted before starting any work.
Note 5) While inserting a tubing into an elbow-type fitting
assembly, hold the main body of the assembly by hand.
Failure to do so will exert an undue force on the valve or
the fitting assembly, resulting in air leakage or damage.
