PIPING (Section 4.3)
！
CAUTION :
a) M ake sure that the pipes will not be disconnected at the
joints by mechanical movements, vibrations or tension.

If the exhaust piping of the pneumatic circuit is discon-
nected, the actuator speed control is disabled.

If the above happens to a chuck holding mechanism, the
chuck will open. The inadvertent opening of the chuck
may cause a serious accident.
b) W hen supplying the compressed air for the first time after
completing the piping, be sure to check every joint in the
piping for air leakage.
c) W hen supplying the compressed air for the first time after
completing the piping, increase the air pressure gradually
but never introduce a highly-pressurized air suddenly.

A sudden introduction of a highly-pressurized air may
disconnect pipes at joints and/or cause the tubes to jump
around, any of which may cause an injury.
d) D o not decrease the inside diameter of the piping from
any of the solenoid valve exhaust ports to a diameter less
than the exhaust pipe connecting port size.

Normal operation of the actuator depends on the
smoothness of the exhaust flow. With a manifold system,
a restriction to the exhaust flow may prevent normal op-
eration of other solenoid valves.
e) R emoval of foreign matter

Rust and other foreign matter in the pneumatic circuit
may cause a malfunction or leakage from the valve seat.
Insert a filter (maximum allowable particle size 5μm or
less) immediately upstream of the solenoid valve.
f) Air supply

Do not restrict the flow of air through the air supply pip-
ing. With a manifold system with multiple stations, a drop
in the air supply pressure may cause trouble through a
delay in the operation timing.
