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.

Note 1: Two wire control, 4 to 20 mADC and 0 to 20 mADC are not available. Supply
voltage of 12-15VDC or 24 VDC is required.
Note 2: Make selection of analogue or switch output; also select NPN or PNP output
when switch output is selected.
Note 3: 1 PSI is the minimum unit on ITV*05*.
Note 4: Value for the state with no over current included. If an allowance is provided
for an over current circuit, the input impedance varies depending on the input
current. This is 350 Ω or less for an input current of 20 mA DC.
3 Operation Principle
ITV2000, ITV3000: When the input signal increases the supply solenoid
valve nturns on and the exhaust solenoid valve oturns off. Supply
pressure is passed to the pilot valve pthrough 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 qwill 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.

Fig. 2 - Schematic diagram for ITV2000 & ITV3000 series
3 Operation Principle (continued)
ITV2090: When the input signal increases, the vacuum solenoid valve n
turns on and the atmospheric pressure solenoid valve oturns off. Because
of this, the VAC and pilot chamber pare connected; the pressure in the
pilot chamber pbecomes negative and acts on the top of the diaphragm.
As a result, the vacuum pressure valve r, which is linked to the diaphragm
q, opens, VAC and OUT are connected, and the set pressure becomes
negative. This negative pressure feeds back to the control circuit svia the
pressure sensor t. Then, a correct operation works until a vacuum
pressure proportional to the input signal is reached, and a vacuum
pressure is obtained which is always 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.

• Release ‘Key Lock ’as explained in section ‘Function of Key-Lock’
• After releasing key lock, SET needs to be pressed again to get to F-1
• To set minimum pressure (display shows F-1) use up/down keys and
press ‘Set’ key to ‘Lock’ setting.
• To set maximum pressure (display shows F-2) use up/down keys and
press ‘Set’ key to ‘Lock’ setting.

9 Installation & Maintenance
• If the electrical supply fails, settings are ‘held’ for a short period.
• If the air pressure fails with power ‘on’ the solenoid will ‘flutter’. Turn off
the power.
• If the monitor output function is not used, ensure that the wire is totally
insulated.
• This product is pre-set at the factory and must not be dismantled by the
user. Contact your local SMC office for advice.
• Ensure, when installing this product, that it is kept clear of power lines to
avoid noise interference.
• Ensure that load surge protection is fitted when inductive loads are
present (i.e. solenoid, relay etc.).
• Ensure precautions are in place if the product is used in a ‘free flow
output ’condition. Air will continue to flow continuously.
• Do not use a lubricator on the input side of this product. If lubrication is
necessary, place the lubricator on the ‘output’ side.
• Ensure all air is exhausted from the product before maintenance.
• Length of connector cable shall be 10 m maximum.
