1. Install an air filter near this product on the
supply side. Select a filtration degree of 5
µm or less.
2. Compressed air containing large amounts of
drainage can cause malfunction of this
product and other pneumatic equipment. As
a countermeasure, install an aftercooler, air
dryer or Drain Catch, etc.
3. If large amounts of carbon dust are gener-
ated by the compressor, it can accumulate
inside this product and cause malfunction.
For details on the above compressed air
quality, refer to Best Pneumatics Vol. 16.
Air Supply
Caution
1. Do not use a lubricator on the supply side of
this product, as this can cause malfunction.
When lubrication of terminal equipment is
necessary, connect a lubricator on the out-
put side of this equipment.
2. If electric power is shut off while pressure is
being applied, pressure will be retained on
the output side.
However, this output pressure is held only
temporarily and is not guaranteed. If ex-
hausting of this pressure is desired, shut off
the power after reducing the set pressure,
and discharge the air using a residual pres-
sure exhaust valve, etc.
3.
If power to this product is cut off due to a
power failure, etc. when it is in a controlled
state, output pressure will be retained
temporarily. Handle carefully when operating
with output pressure released to the
atmosphere, as air will continue to flow out.
Handling
Caution
4. If supply pressure to this product is
interrupted while the power is still on, the
internal solenoid valve will continue to
operate and a humming noise may be
generated. Since the life of the product may
be shortened, shut off the power supply also
when supply pressure is shut off.
5. In this product, the output side pressure can-
not be completely relieved within the range
of 0.005 MPa or less. If it is desired to reduce
the pressure completely to 0 MPa, install a 3
way valve or other device on the output side
to exhaust the pressure.
6. This product is adjusted for each specifica-
tion at the time of shipment from the factory.
Avoid careless disassembly or removal of
parts, as this can lead to malfunction.
7. The optional cable connector is a 4 wire type.
When the monitor output (analog output or
switch output) is not being used, keep it from
touching the other wires as this can cause
malfunction.
8. Please note that the right angle cable does
not rotate and is limited to only one entry
direction.
9. Take the following steps to avoid malfunc-
tion due to noise.
1) Remove power supply noise during operation by installing a
line filter, etc. in the AC power line.
2) For avoiding the influence of noise install this product and its
wiring as far as possible from strong electric fields such as
those of motors and power lines, etc.
3) Be sure to implement protective measures against load
surge for induction loads (solenoid valves, relays, etc.).
4) Install or remove the connector after shutting off the power
supply to avoid the influence of chattering of the power
supply.
10. Due to the large volume of the output side, a
loud exhaust noise will be produced when
being used for the purpose of a relief
function. Therefore, install a silencer (SMC
Series AN200 or AN400) on the exhaust port
(EXH port). The port sizes are Rc1/8, Rc1/4
and Rc1/2.
11. Specifications on page 1 is in case of static
environment. Pressure may fluctuate when
air is consumed at the output side.
12. For details on the handling of this product,
refer to the instruction manual which is
included with the product.
Handling
Caution
Operating Environment
1. Employ suitable protective measures in
locations where there is contact with water
droplets, oil or welding spatter, etc.
2. Consult SMC when used in power plants, or
if instrumentation related.
