These safety instructions are intended to prevent a hazardous
situation and / or equipment damage. These instructions indicate
the level of potential hazard by label of “Caution” “Warning”, or
“Danger”. To ensure safety, be sure to observe ISO 4414

(Note 1)

, JIS

B 8370

(Note 2)

and other safety practices.
(Note1): ISO 4414: Pneumatic fluid power-Recommendations for
the application of equipment to transmission and control systems.
(Note 2): JIS B 8370: Pneumatic system axiom

CAUTION

: Operator error could result in injury or equip-

ment damage.

WARNING

: Operator error could result in serious injury

or loss of life.

DANGER

: In extreme conditions, there is a possible result

of serious injury or loss of life.

1. The compatibility of pneumatic equipment is the

responsibility of the person who designs the
pneumatic system or decides its specifications.

Since the products specified here are used in various
operating conditions, their compatibility for the specific
pneumatic system must be based on specifications or after
analysis and/or tests to meet your specific requirements.

2. Only trained personnel should operate
pneumatically operated machinery and equipment.

Compressed air can be dangerous if an operator is unfamiliar
with it. Assembly, handling or repair of pneumatic systems
should be performed by trained and experienced operators.

3. Do not service machinery / equipment or attempt to
remove component until safety is confirmed.

1) Inspection and maintenance of machinery / equipment

should only be performed after confirmation of safe
locked-out control positions.

2) When equipment is to be removed, confirm the safety

process as mentioned above. Switch off air and electrical
supplies and exhaust all residual compressed air in the
system.

3) Before machinery / equipment is re-started, ensure all

safety measures to prevent sudden movement of
cylinders etc. (Supply air into the system gradually to
create back-pressure, i.e. incorporate a soft-start valve.)

4. Contact SMC if the product is to be used in any of
the following conditions:

1) Conditions and environments beyond the given

specifications, or if product is used outdoors.

2) Installation on equipment in conjunction with atomic

energy, railway, air navigation, vehicles, medical
equipment, food and beverage, recreation equipment,
emergency stop circuits, press applications, or safety
equipment.

3) An application which has the possibility of having

negative effects on people, property, or animals requiring
special safety analysis.

Ensure that the air supply system is filtered to 5 micron

(Note 1) Excludes current consumption of DeviceNet communication line.
(Note 2) Select Set pressure with 4096 resolution, corresponding to the maximum setting pressure of 100%
(Note 3) Select monitor pressure with 4096 resolution, corresponding to the maximum output pre ssure of 100%

Fig 3

When the input signal increases, the supply solenoid valve  tu rns on and the exhaust solenoid valve  turns off. Supply pressure is
passed to the pilot valve  through the supply solenoid valve. The pilot valve will open the main valve allowing partial supply pressure to
pass to the out port.

The pressure sensor  will provide output pressure feedback to the control circuit . The control circuit will balance the input signal and
output pressure to ensure that the output pressure remains proportional to the input signal.

Connect the cables to the connectors on the unit as shown i n the
following diagrams. Take precautions as incorrect wiring will
damage the unit. Use a DC power supply capable of supplying the
necessary power requirements with minimal ripple.

When 3m straight cable connection is specified, this refers to the
power supply cable, the communications cable should be ordered
separately.

1. The setting of an address switch requires the removal of 4
screws in the front panel of the unit (Fig 6). Take care that the
panel hinges to 90 degrees maximum.

2. After setting an address, always close and fix the panel
securely. Tighten the screws to a torque of 0.6 – 1.0 Nm.

1. If the air pressure fails with power ‘on’ the solenoid will
‘flutter’. Turn off the power to stop the pressure supply or
make an input signal of 0%

1. This product is pre-set at the factory and must not

be
dismantled by the user. Contact your local SMC office for
advice.

2. Ensure, when installing this product, that it is kept clear of
power lines to avoid noise interference.

3. Ensure that load surge protection is fitted when inductive
loads are present (i.e. solenoid, relay etc.).

4. Ensure precautions are in place if the product is used in a
‘free flow output’ condition. All will continue to flow
continuously.

5. Do not use a lubricator on the input side of this product. If
lubrication is necessary, place the lubricator on the ‘output’
side.

6. Ensure all

air is exhausted form the product before

maintenance.
