The pressure sensor detects the differential pressure generated when the detection nozzle (S4) is not occluded. When the work piece comes close to the detection nozzle, the backing pressure P increases until it is larger than P (P>P). Then the switch output turns on to notify that the pressure is below the detection gap.

19 Series ISA Common Precautions Be sure to read before handling. Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside the range of the specified voltage can cause not only malfunction and damage to the switch but also electric shocks and fire.. Never apply a load above the maximum load capacity. It can damage the air catch sensor or shorten the life time.. Do not use a load that generates surge voltage. Although the output circuit of the air catch sensor is equipped for surge protection, repeated application of surges can damage the air catch sensor. When a load, such as a relay or solenoid, which generates surge is directly driven, use a type of switch having a built-in surge absorbing element. 4. Be sure to observe the set pressure range and maximum operating pressure. Use of the air catch sensor outside the range of the specified pressure can cause failure. Use at a pressure exceeding the maximum operating pressure may damage the air catch sensor. 5. Be aware of internal voltage drops of the air catch sensor. When the air catch sensor is used below the specified voltage, even if the air catch sensor operates normally, the load may fail to operate. Confirm the operating voltage of the load and adjust it to satisfy the formula below. Power supply - Internal voltage drop voltage of air catch sensor > Load. Quality of operating air. Use clean air. Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction.. Install air filters. Install air filters at the upstream side of valves, The filtration degree should be 5µm or finer.. Install an after cooler, air dryer or water separator, etc. Air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an after cooler, air dryer or water separator, etc. Warning Mounting. Do not use the switch unless it operates normally. After installation, repair or reform, connect air and electricity and conduct appropriate function and leakage tests to confirm proper installation.. Observe the prescribed tightening torque in installation. If screws are tightened with a force beyond the tightening torque range, it can cause damage to the mounting screws, mounting brackets and switches. If the force is below the tightening torque range, the fixing screws can come loose during operation. connection thread :/8, /4 Nominal size /8 /4 Warning Proper tightening torque N m 7 to to 4. Detection port Do not insert wire, etc. into pressure port. It will damage the pressure sensor and cause malfunction. Maintenance. Removal of the product. Shut off the fluid supply and release the fluid pressure inside the system.. Shut off the power supply.. Remove the product.. Perform periodic inspections to confirm proper operation. Unexpected malfunctions or incorrect operation can cause possible danger.. Be careful when using the air catch sensor in an interlocking circuit. When using the air catch sensor in an interlocking circuit, build a multiple interlocking system to prevent trouble or malfunction. At the same time, preform periodic inspections to confirm proper operation. Caution. When the body becomes dirty. Wipe off dirt with soft cloth. In case of heavy dirt, soak the cloth in neutral detergent diluted with water, wring the water out, wipe off the dirt with the cloth and finish with dry cloth.

20 Series ISA Common Precautions Be sure to read before handling. Warning Warning Wiring. Confirm the colors and terminal numbers of the wires when connecting. Incorrect wiring can lead to damage, failure and malfunction. Confirm colors and terminal numbers in the operation manual when wiring.. Avoid repeatedly bending or stretching lead wires. Broken wires will result from applying repeated bending stress or stretching force to the lead wires. Replace any lead wire that is damaged and can possibly cause malfunction.. Confirm proper insulation of wiring. Be certain that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.) Damage may occur due to excess current flow into an air catch sensor. 4. Do not run wiring near power lines or high voltage lines. Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines. Control circuits containing auto switches may malfunction due to noise from these other lines. 5. Do not allow short circuit of loads. Take special care to avoid reverse wiring with the power supply line (brown) and the output line (black). Operating Environment. Never use in an atmosphere of explosive gases. The construction of air catch sensor is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this may cause a serious explosion.. Do not use in an environment consisting of corrosive gases, sea water, water, vapor or in hostile environment generally.. Do not subject to excessive vibration. 4. Do not use close to flame. 5. Take proper protection measures in an environment where water splashes, oil or spatters from welding may adhere to the product.. Do not use in locations where surge is generated. If there is equipment generating a large surge (such as a solenoid lifter, high frequency induction furnace or motor) around the air catch sensor, it can deteriorate or damage the circuit elements inside the air catch sensor. Apply surge protection measures to the source of the surge and keep the lines apart from each other. Pressure Source Warning. Use the air catch sensor within the specified fluid and ambient temperature range. The fluid temperature and ambient temperature are to C. Take measures to prevent freezing, since moisture in circuits may be frozen at or below 5 C, which can cause damage the O-ring and lead to malfunction. Installation of an air dryer is recommended to remove drain and moisture. Do not use the air catch sensor in an environment with sudden temperature changes even if the ambient temperature range is compliant with the specifications. Caution Piping. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Do not allow tensile, contracting or bending forces by piping to be applied to the valve body.. Wrapping of pipe tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping. Also, when pipe tape is used, leave.5 to thread ridges exposed at the end of the threads. Wrapping direction Expose approx. threads Pipe tape 7

21 Series ISA Specific Product Precautions Be sure to read before handling. Air Catch Sensor Series ISA Warning Operating Environment. Do not use in an environment where vibration or impact occurs. Use a bracket in an environment with vibration exceeding m/s.. The enclosure of the switch conforms to IP and that for the solenoid valve to IP5. The pressure gauge and the regulator have open constructions. Take proper protection measures in an environment where water splashes, oil or spatters from welding may adhere to the product.. Since stainless steel piping lacking flexibility is easily affected by moment loads or propagation of vibration, employ flexible tubing, etc., to prevent interactions of such factors. Caution. When an air catch sensor is contained in a box, provide an air outlet to constantly keep the atmospheric pressure inside the box. Internal pressure rises will hinder normal air discharge and may lead to possible malfunction.. The air outlet is provided on the setting dial section of the air catch sensor. Do not turn off air supply to the switch if water or cutting oil splashes around the setting dial. Caution Mounting. If the detection nozzle is exposed to splashes of water or cutting oil, do not allow backflow from the detection nozzle to the switch body. Install the switch body at a position higher than the detection nozzle wherever possible. Caution. Piping equipment In the piping between the switch body and the detection noise, do not use equipment or fittings that can possibly cause leakage or serve as resistance. Do not use one-touch fittings in an environment where the air catch sensor is exposed to water or other liquid. Pressure Source Caution Piping. Supply air Since the orifice of the air catch sensor is small, prevent foreign matter from entering the equipment. For this purpose, use supply air that is dry and filtered 5µm or better.. Operating pressure Since the product adopts a semiconductor pressure sensor, keep the operating pressure not larger than. MPa. Port Solenoid Valve Series VCA Warning Precautions on Design. Energized continuously Consult SMC if the product is to be energized continuously for long periods of time. Caution Selection. Leakage voltage Take special precautions if a resistor is used in parallel with the switching element or a C-R element (for surge voltage protection) is used for protection of the switching element. The valve may fail to turn off due to leakage current flowing through the resistor or C-R element. Power supply Switching element C OFF R Leakage voltage AC coil % or less rated voltage Warning Leakage voltage Mounting DC coil % or less rated voltage Valve. Do not use the air catch sensor if the leakage amount increases or the equipment does not operate properly. After installation, connect compressed air and electricity and conduct an appropriate functionality inspection to confirm that the air catch sensor is installed properly.. Do not apply external force to the coil. Apply a wrench to the exterior surface of the piping joint at the time of tightening.. Do not use heat insulators, etc. to keep the temperature at the coil assembly. Do not use a tape heater for freeze prevention except on the piping and body. If may cause the coil to burn. 8
