Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations.
Safety Instructions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing industries. Use in non-manufacturing industries is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
Operating Environment Warning ① Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. ② Do not operate in locations where vibration or impact occurs. ③...

⑬ When using the IR3200-A series in balancing applications, abnormal noises may occur depending on the pressure and circuit conditions. In such cases, the noise will often cease if changes are made to the pressure or piping conditions or if a high noise reduction type silencer (such as SMC’s ANA1 series, etc.) is installed...

② Do not allow twisting or bending moment to be applied other than the weight of the equipment. Provide separate support for external piping, as damage may otherwise occur. ③ Piping materials without flexibility such as steel tube piping are prone to be effected by excess moment load and vibration from the piping side.
Air Supply Warning ① The operating fluid must be compressed air. ② Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as this can cause damage or malfunction. ③ If condensate in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow the condensate to enter the outlet side.
1. Application This instrument aims at controlling pressure of air lines. Specifications 2. Model IR320(0,1,2)-A IR321(0,1,2)-A IR322(0,1,2)-A Max. supply pressure [ MPa] Min. supply pressure Set pressure + 0.1 (Note 1) [MPa] Set pressure range 0.02 to 0.2 0.02 to 0.4 0.02 to 0.8 [MPa] (Note 3)
3. Construction and Operation Principles When the knob is rotated, the flapper is pushed through the spring, and a gap is generated between the nozzle and flapper. The supply pressure flows to the inlet passes through the path between the nozzle and flapper and acts on the supply / exhaust diaphragm as nozzle pressure.
Bracket, gauge and switch assembly (optional) 5. 1. Bracket 1) Installation of bracket (Grooved) Set nut Mount the bracket to the regulator as shown on the picture. Assemble so that the regulator and rotation stopper of the bracket align properly. Bracket 2) Holding with the set nut (Knurled tool face)
6.Panel mounting 1. Panel mounting 1) Handle removal Remove the handle from the regulator. Handle 2) Panel mounting Insert the regulator into the panel. 3) Nut tightening Hexagon panel nut Adjust the regulator position and tighten the attached hexagon panel nut. Recommended tightening torque Panel Wrench size [mm]...
7.Troubleshooting Problem Possible causes Countermeasures Set the pressure again. Fluctuation of flow rate at the downstream side Return the flow rate at the downstream side to the initial rate. Ozone Use the ozone resistant product (80- series). Leakage due to deterioration of the Temperature Avoid using at high temperature or low temperature.
