Solenoid (Surge suppression)
Order code: -SR
Cautions: 1. Do not apply megger between the
lead wires.
2. The DC solenoid will not short circuit even if the wrong polarity is
applied, but the surge suppression
solenoid valve will not operate. In
addition, in solenoids with an LED
indicator, the LED will not light up.
3. Leakage current inside the circuit
could result in failure of the solenoid
valve to return, or in other erratic
operation. Always use it within the
range of the allowable leakage current. If circuit conditions, etc. cause
the leakage current to exceed the
maximum allowable leakage current, consult us.
4. For a double solenoid valve, avoid
energizing both solenoids simultaneously. The valve could fall into
the neutral position.
5. Since the AC solenoid uses diodes
for the solenoid, always use lead
wires of the same color when connecting a number of solenoid units
in parallel. The DC24V standard
solenoid, however, has no polarity,
so either lead wire connection is
acceptable.
DIN connector
Wiring instructions
Remove the cover mounting screws, and lift the
terminal cover off from the solenoid. Use a screwdriver (blade width 4 〜 4.5mm [0.16 〜 0.18in.]), etc.
to push strongly against the terminal body through
the hole of the terminal cover’s mounting screw,
and remove the terminal body.
Slip a cable gland, washer, and cable gasket over
a cable (outer diameter 6 〜 8mm [0.24 〜 0.31in.]),
insert the cable into the terminal cover’s wiring port,
and connect the lead wire to the terminal body
(screwdriver blade width of about 3mm [0.12in.]).

Manual override
Non-locking type
To operate the manual override, press it all
the way down. The valve works the same as
when in the energized state as long as the
manual override is pushed down, and
returns to the rest position upon release.
For the double solenoid, pressing the manual override on the 12(S1) side switches the
12(S1) to the energized state, and the unit
remains in that state even after the manual
override is released. To return it to the rest
position, operate the manual override on the
14(S2) side. This is the same for the solenoid 14(S2).

To obtain the time required for the
cylinder to complete 1 stroke, add
the cylinder’s delay time t 1 (time
between energizing of the solenoid
valve and actual starting of the
cylinder), to the cylinder’s max.
speed operating time t 2. When a
cushion is used, add the cushioning
time t3, to the above calculations.
The standard cushioning time t3 is
approximately 0.2 seconds.
