Electro-Pneumatic Regulator

Series

ITV2000/3000

Working Principles When the input signal rises, the air supply solenoid valve (1) turns ON, and the exhaust solenoid valve (2) turns OFF. Therefore, supply pressure passes through the air supply solenoid valve (1) and is applied to the pilot chamber (3). The pressure in the pilot chamber (3) increases and operates on the upper surface of the diaphragm (4). As a result, the air supply valve (5) linked to the diaphragm (4) opens, and a portion of the supply pressure becomes output pressure. This output pressure feeds back to the control circuit (8) via the pressure sensor (7). Here, a correct operation functions until the output pressure is proportional to the input signal, making it possible to always obtain output pressure proportional to the input signal.

ITV2000/3000 Precautions

Be sure to read before handling. Refer to p.0-26 and 0-27 for Safety Instructions and p.1.0-1 and 1.0-2 for precautions.

Oprating Environment

Warning

Caution

qIn locations where there is contact with spatter from water, oil or solder, etc., implement suitable protective measures. Air Supply

Caution qInstall an air filter near this product on the supply side. Select a filtration degree of 5µm or less. wCompressed air containing large amounts of drainage can cause malfunction of this product and other pneumatic equipment. As a countermeasure, install an aftercooler, air dryer or Drain Catch, etc. eIf large amounts of carbon dust are generated by the compressor, it can accumulate inside this product and cause malfunction. For details on the above compressed air quality, refer to SMC's "Air Preparation Equipment". Handling

Caution qDo not use a lubricator on the supply side of this product, as this can cause malfunction. When lubrication of terminal equipment is necessary, connect a lubricator on the output side of this equipment. wIf electric power is shut off while pressure is being applied, pressure will be retained on the output side. However, this output pressure is held only temporarily and is not guaranteed. If exhausting of this pressure is desired, shut off the power after reducing the set pressure, and discharge the air using a residual pressure exhaust valve, etc. eIf power to this product is cut off due to a power failure, etc. when it is in a controlled state, output pressure will be retained temporarily. Handle carefully when operating with output pressure released to the atmosphere, as air will continue to flow out. 1.12-10

Handling

rIf supply pressure to this product is interrupted while the power is still on, the internal solenoid valve will continue to operate and a humming noise may be generated. Since the life of the product may be shortened, shut off the power supply also when supply pressure is shut off. tIn this product, the output side pressure cannot be completely relieved within the range of 0.005MPa or less. If it is desired to reduce the pressure completely to 0MPa, install a 3 way valve or other device on the output side to exhaust the pressure. yThis product is adjusted for each specification at the time of shipment from the factory. Avoid careless disassembly or removal of parts, as this can lead to malfunction. uThe optional cable connector is a 4 wire type. When the monitor output (analog output or switch output) is not being used, keep it from touching the other wires as this can cause malfunction. iPlease note that the right angle cable does not rotate and is limited to only one entry direction. oTake the following steps to avoid malfunction due to noise. 1) Remove power supply noise during operation by installing a line filter, etc. in the AC power line. 2) Install this product and its wiring as far as possible from strong electric fields such as those of motors and power lines, etc. 3) Be sure to implement protective measures against load surge for induction loads (solenoid valves, relays, etc.).

!0Due to the large volume of the output side, a loud exhaust noise will be produced when being used for the purpose of a relief function. Therefore, install a silencer (SMC Series AN200 or AN400) on the exhaust port (EXH port). The port sizes are Rc1/4 and Rc1/2. !1For details on the handling of this product, refer to the instruction manual which is included with the product.
