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 ISO4414
(Note1)
, JIS B 8370
(Note2)
and other safety practices.
Note 1: 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 specifica-
tions, or if product is used outdoors.
2) 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.
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.

Operation Principal (Fig 4)
When the input signal increases,the supply solenoid valve 1 turns on and the exhaust solenoid valve 2 turns off. Supply pressure is passed to
the pilot valve 3 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 4 will 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.
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).

Setting the Regulator
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.
Switch output PNP/NPN
• 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 switch output.
Note 1:If the above sequence of events has been followed
correctly,the settings will complete automatically.
Note 2:If only setting minimum pressure, when pressure is
'set', pressing the set button once more will 'skip' to
the next step.
Function of Key-Lock
With input signal applied
a b
j Push 'down' key (Fig 1) for longer than 2 seconds.Display (a)
flashes 'loc'.
1. Push 'set' key (Fig 1) lock automatically releases.
Note: Push 'down' key (Fig 1) again to cancel operation.
2. Key Lock Release
1. Push down on 'un-lock' (Fig 1) key for longer than 2 seconds.
2. Key-lock will release.
Note: To cancel push 'lock' key (Fig 1).
3. To Lock
1. Push down on 'up' i (Fig 1) for longer than 2 seconds.
2. Led will flash 'unL' (un-lock).
3. Push 'set' key (Fig 1) to lock.
Note: To cancel push 'down' key (Fig 1).
Function of the 'Error' Display
If an abnormality is detected by the ITV2000, the LED display (Fig 1)
will show 'Er' followed by a code number. Isolate the power supply
and ascertain and solve the problem. Re-instate power supply after
correcting the fault.
Error codes are as follows:
No Content Display
1 Input Signal Outside Spec. Er 1
2 EEProm Reading/Writing Error Er 2
3 Memory Reading/Writing Error Er 3
4 Solenoid Valve Fault Er 4
5 Switch Output Over-Current Er 5
Reset Function
Push up and down keys (Fig 1) together for longer than 3 seconds.
Display (Fig 1) shows 'RES'. Release keys, minimum, maximum
pressures, switch outputs P1 and P2 are reset to start condition.
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’.
Turn off the power.
3. If the monitor output function is not used, ensure that the wire is
totally insulated.
PNP Circuit
Note: If the supply exceeds 30mA the sensor will output
to the LED display (Fig 1) and show 'Er 5'.
CAUTIONS
1. This product (ITV2000) 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 from the product before maintenance.
