Operation Principle
When the input signal increases, the supply solenoid valve turns on and the exhaust solenoid valve
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
output pressure to ensure that the output pressure remains proportional to the input signal.

Wiring
Connect the cables to the connectors on the unit as shown in 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.

Note: Dip switch 9 is selected to temporarily hold or clear the
output pressure, in the event that either of the following
occur
1. When the DeviceNet line causes a communication error due
to disconnection.
2. When the power supply to the ITV is switched off or
disconnected whilst unit is communicating.
The condition of the output pressure during recovery of either
connection depends on the position of the dip switch.
0 Output pressure is Cleared
1 Output pressure is Held
CAUTION
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.
CAUTION
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%
CAUTION
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.
