Table 7.
3.9 Countermeasure for surge voltage
Caution
•At times of sudden interruption of the power supply, the energy stored
in a large inductive device may cause non-polar type valves in a de-
energised state to switch.
•When installing a breaker circuit to isolate the power, consider a valve
with polarity (with polarity protection diode), or install a surge
absorption diode across the output of the breaker.
3.10 Extended periods of continuous energization
Caution
•When the product is continuously energized for a long period of time
(10 minutes or longer), select the low wattage type.
•Refer to ‘3, 4, 5 port solenoid valves precautions’ for more details.
•When solenoid valves are mounted in a control panel, employ
measures to radiate excess heat, so that temperatures remain within
the valve specification range. Use special caution when three or more
stations sequentially aligned on the manifold are continuously
energized since this will cause a drastic temperature rise.
3.11 Air supply Warning
•Use clean air. If the compressed air supply includes chemicals,
synthetic materials (including organic solvents), salinity, corrosive gas
etc., it can lead to damage or malfunction.
Caution
•Install an air filter upstream near the valve. Select an air filter with a
filtration size 5 μm or smaller.
3.12 Effect of back pressure when using a manifold
Warning
•Use caution whenvalves are usedon a manifold, because an actuator
may malfunction due to back-pressure.
•For a 3-position exhaust centre valve or single acting cylinder, take
appropriate measures to prevent malfunction by using it with an
individual EXH interface block.
3 Installation - continued
3.13 Manual override Warning
•Regardless of an electric signal for the valve, the manual override is
used for switching the main valve. Since connected equipment will
operate when the manual override is activated, confirm that conditions
are safe prior to activation.
•Locked manual overrides might prevent the valve responding to being
electrically de-energised or cause unexpected movement in the
equipment.
•Refer to the catalogue for details of manual override operation.
•Do not apply excessive torque when turning the locking type manual
override, (0.1 N∙m or less).
3.14 External pilot exhausts Caution
The external pilot variants use the exhaust port of the manifold. Ensure
that this connection is always vented to atmosphere and do not block the
exhaust port when arranging the piping.

6.1 General maintenance Caution
•Not following proper maintenance procedures could cause the product
to malfunction and lead to equipment damage.
•If handled improperly, compressed air can be dangerous.
•Maintenance of pneumatic systems should be performed only by
qualified personnel.
•Before performing maintenance, turn off the power supply and be sure
to cut off the supply pressure. Confirm that the air is released to
atmosphere.
•After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
•If any electricalconnections are disturbed duringmaintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.
•When the 3-position closed centre type is in its rest position, air can be
trapped between the valve and the cylinder. Exhaust this air pressure
before removing piping or performing any maintenance.
•When the equipment is operated after remounting or replacement, first
confirm that measures are in place to prevent lurching of actuators,
etc. Then, confirm that the equipment is operating normally.
•Operate thevalve according tothe minimum operating frequency given
in section 2.
•For maintenance purposes install a system for releasing residual
pressure. Especially in the case of 3-position closed centre valve or
double check valve type, ensure that the residual pressure between
the valve and the cylinder is released.
•Dust on sealing surfaces of the gasket of solenoid valve can cause air
leakage. Ensure gaskets are in place and parts are dust free.

7.5 Air returned or air/spring returned spool valves
Warning
•The use of 2-position single valves with air returned or air/spring
returned spools has to be carefully considered.
•The return of the valve spool into the de-energized position depends
on the pilot pressure. If the pilot pressure drops below the specified
operating pressure the position of the spool cannot be defined.
•The design of the system must take into account such behaviour.
•Additional measures might be necessary. For example, the installation
of an additional air tank to maintain the pilot pressure.
