3.10 Residual voltage Caution
•If a varistor voltage suppressor is used, the suppressor arrests the
back EMF voltage from the coil to a level in proportion to the rated
voltage.
•Ensure the transient voltage is within the specification of the host
controller.
•Contact SMC for the varistor residual voltage.
•In the case of a diode, the residual voltage is approximately 1 V.
•Valve response time is dependent on surge suppression method
selected.
3.11 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.
3.12 Extended period of continuous energization
Warning
•If a valve will be continuously energized for an extended period of time,
the temperature of the valve will increase due to the heat generated by
the coil assembly. This will likely adversely affect the performance of
the valve and any nearby peripheral equipment. Therefore, if the valve
is to be energized for periods of longer than 30 minutes at a time or if
during the hours of operation the energized period per day is longer
than the de-energized period, we advise using a valve with
specifications of 0.4 W or lower valve, such as the SY series, or a valve
with a power-saving circuit.
3.13 Effect of back pressure when using a manifold
Warning
•Use caution whenvalves are used on a manifold, because an actuator
may malfunction due to back-pressure.
•Special caution must be taken when using 3 position exhaust centre
valve or when driving a single acting cylinder. To prevent a
malfunction, implement counter measures such as using a single EXH
spacer assembly or an individual exhaust manifold.
4 How to Order

7 Limitations of Use
Warning
The system designer should determine the effect of the possible failure
modes of the product on the system.
7.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
Warning
7.2 Effect of energy loss on valve switching
•The use of 2-position single valves with combined air and 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.

7.4 Holding of pressure
Since valves are subject to air leakage, they cannot be used for
applications such as holding pressure (including vacuum) in a system.
7 Limitations of Use - continued
7.5 Cannot be used as an emergency shut-off valve
This product is not designed for safety applications such as an
emergency shut-off valve. If the valves are used in this type of system,
other reliable safety assurance measures should be adopted.
Caution
7.6 Safety relays or PLC
If a safe output from a safety relay or PLC is used to operate this valve,
ensure that any output test pulse duration is shorter than 1 ms to avoid
the valve solenoid responding.
7.7 Leakage voltage
Ensure that any leakage voltagecaused by the leakage current when the
switching element is OFF causes ≤3% (for DC coils) or ≤20% (for AC
coils) of the rated voltage across the valve.
7.8 Low temperature operation
Unless otherwise indicated in the specifications for each valve, operation
is possible to -10˚C, but appropriate measures should be taken to avoid
solidification or freezing of drainage and moisture, etc.
7.9 Momentary energization
If a double solenoid valve is operated with momentary energization, it
should be energized for at least 0.1 second. However, depending on the
secondary load conditions, it should be energized until the cylinder
reaches the stroke end position, as there is a possibility of malfunction
otherwise.
