Pneumatic Clean Series

Precision Regulator 10-IR1000/2000/3000529Specific Product PrecautionsRefer to pages 7 to 16 of Front matter for safety instructions and common precautions for clean series and pages472 and 473 for common precautions for air line equipment.CautionAir SupplyqIf the supply pressure line contains drainage or dirt,etc., the fixed throttle can be clogged andmalfunction. In addition to an air filter (SMC SeriesAF), be sure to use a mist separator (SMC SeriesAM, AFM).Refer to SMC's Compressed Air Cleaning Systems catalogregarding air quality.wNever use a lubricator on the supply side of theregulator because this will inevitably cause thefixed throttle to be clogged, resulting inmalfunction. If lubrication is required for terminaldevices, connect a lubricator on the output side ofthe regulator.WarningMaintenanceqWhen the valve guide is to be removed duringmaintenance, first reduce the set pressure "0" andcompletely shut off the supply pressure.wWhen installing a pressure gauge, lower the setpressure to "0" before removing the plug.Precautions for 10-IR100 onlyWarningqWhen remounting the valve guide after removing itfor maintenance, use a tightening torque of 0.6Nmor smaller.Since the valve guide on this product is made ofresin, there is a danger of damage if tightened with atorque exceeding the prescribe range.CautionOperationqDo not use a precision regulator outside the rangeof its specifications. It can cause failure. (Refer tospecifications.)wIn mounting, confirm the port indications beforeconnecting.eIf a directional switching valve (solenoid valve,mechanical valve, etc.) is mounted on the supplyside of the regulator and repeatedly switched ONand OFF, wear of the nozzle/flapper section will beaccelerated and a discrepancy in the setting valuemay result. Therefore, avoid using a directionalswitching valve on the supply side. If a directionalswitching valve is to be used, install it on theoutput side of the regulator.rAir is constantly discharged from the bleed port(the hole on the body's mid-section). Thisconsumption of air is required by the constructionof the precision regulator and is not an abnormality.tBe sure to tighten lock nut after pressureadjustment.Precautions for 10-IR300, IR3120 onlyCautionqIf the supply pressure is relatively high (approx. 0.5MPa or more) and the set pressure (approx. 0.1MPaor less) low, and if the output side is released to theatmosphere, pulsation in the set pressure mayresult. In such cases, operate at the lowest possiblesupply pressure or raise the set pressure slightlyand restrict the output line (by using an additionalstop valve, etc. for control).wIf the product is used for a relief function with alarge capacity on the output side, there will be alarge exhaust sound at the time of relief. Therefore,install a silencer (SMC Series AN) on the exhaustport (EHX port). The connection is Rc1/2.Precautions for 10-IR2120, IR3120(air operated type) onlyCautionqThe output pressure of model IR2120 and 3120 is thesame as the input signal pressure. Select the type ofregulator (general purpose or precision type) thatmatches the application to control the input signal.wThe screw on the topmost section is a zero pointadjustment screw which is locked at the factory andrequires no adjustment for operation.510
