Safety Instructions
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
equipment 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.
WARNING
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. (Bleed
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.
CAUTION
Ensure that the air supply system is filtered to 5 micron.
Specifications
Operation Principal ITV2000(Fig 3)
When the input signal increases, the supply solenoid valve ①turns on and the exhaust solenoid valve ②turns off. Supply pressure is
passed to the pilot valve ③through 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 ④will provide output pressure feedback to the control circuit ⑤. The control circuit will balance the input signal and
output pressure to ensure that the output pressure remains proportional to the input signal.
Operation Principal ITV2000(Fig 4)
When the input signal increases, the vacuum solenoid valve ①turns ON, and the atmospheric pressure solenoid valve ②turns OFF.
Because of this, VAC and pilot chamber ③are connected, the pressure in the pilot chamber ③becomes negative and acts on the top of the
diaphragm. As a result, the vacuum pressure valve ⑤which is linked to the diaphragm ④opens, VAC and OUT are connected, and the set
pressure becomes negative.
This negative pressure feeds back to the control circuit ⑧via the pressure sensor ⑦. 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.

CAUTION
1. If the electrical supply fails, settings are ‘held’ for a short period.
2. If the air pressure fails with power ‘on’ the solenoid will ‘flutter’.
3. If the monitor output functions is not used, ensure that the wire is
totally insulated.

CAUTION
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.
Note: The right angle type connector extends to the left side (over the
supply port side).

CAUTION
As soon as the ‘set’ key is operated minimum/maximum pressure will be
present at the outlet port.
CAUTION
As soon as primary pressure is applied to the regulator minimum pressure
will be present at the outlet port.
・Release ‘lock key’ (Fig 1) as explained in section ‘Function of key-lock’
・To set minimum pressure (display shows F-1 Fig 1) use up/down keys
(Fig 1) to set minimum pressure, press ‘set’ key(Fig 1) to ‘lock ’
setting.
・To set maximum pressure(display shows F-2 Fig 1) use up/down keys
(Fig 1) to set maximum pressure, press ‘set’ key(Fig 1) to ‘lock’
setting.
・To set switch output 1 (display shows P-1 Fig 1) use up/down keys to set
switch output, press ‘set’ key(Fig 1) to ‘lock’ setting.
・To set switch output 2 (display shows P-2 Fig 1) use up/down keys to set
