Operation Principal (Fig 4)
When the input signal increases, the supply solenoid valve turns on and the exhaust solenoid valve
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 . The control circuit will balance the input signal and out-
put pressure to ensure that the output pressure remains proportional to the input signal.

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.
2: (White)
• 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.

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.
2 EEProm Reading/Writing Error
3 Memory Reading/Writing Error
4 Solenoid Valve Fault
5 Switch Output Over-Current
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.

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.
