1 Safety Instructions
This manual contains essential information for the protection of users and
others from possible injury and/or equipment damage.
•
Read this manual before using the product, to ensure correct handling,
and read the manuals of related apparatus before use.
•
Keep this manual in a safe place for future reference.
•
These instructions indicate the level of potential hazard by label of
“Caution”, “Warning” or “Danger”, followed by important safety
information which must be carefully followed.
•
To ensure safety of personnel and equipment the safety instructions in
this manual and the product catalogue must be observed, along with
other relevant safety practices.
Caution
Indicates a hazard with a low level of risk, which if
not avoided, could result in minor or moderate
injury.
Warning
Indicates a hazard with a medium level of risk,
which if not avoided, could result in death or
serious injury.
Danger
Indicates a hazard with a high level of risk, which if
not avoided, will result in death or serious injury.
•
Electromagnetic compatibility:
This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted as
well as radiated disturbances.
•
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 can be used in various operating
conditions, their compatibility with the specific pneumatic system must
be based on specifications or after analysis and/or tests to meet specific
requirements.
•
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 personnel.
•
Do not service machinery/equipment or attempt to remove
components until safety is confirmed.
•
Inspection and maintenance of machinery/equipment should only be
performed after confirmation of safe locked-out control positions.
•
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.
•
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).
•
Do not use this product outside of the specifications. Contact SMC
if it is to be used in any of the following conditions:
•
Conditions and environments beyond the given specifications, or if the
product is to be used outdoors.
•
Installations in conjunction with atomic energy, railway, air navigation,
vehicles, medical equipment, food and beverage, recreation equipment,
emergency stop circuits, press applications, or safety equipment.
•
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 microns.

3 Operation Principle
When the input signal increases the supply solenoid valve
n
turns on and
the exhaust solenoid valve
o
turns off. Supply pressure is passed to the
pilot valve
p
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
q
will provide output pressure feedback to the control
circuit
r
. The control circuit will balance the input signal and output
pressure to ensure that the output pressure remains proportional to the
input signal.

4 Wiring
Connect the cable to the connector on the main unit as shown in the
following diagram. 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 3 m straight cable connection is
specified, this refers to the power supply cable, the communications cable
should be ordered separately.

Setting the address switch requires the removal of 4 screws in the front
panel of the unit (Fig 3). Take care as the panel hinges to a maximum of
90 degrees.
•
After setting an address, always close and fix the panel securely.
