Working Principle SUP port S S P Sensor S EXH port P Detection port S, S: Fix orifice S: Variable orifice (adjusted by setting dial) S4: Detection nozzle S4 In a bridge circuit as in the left figure, a detection gap is applied to the detection nozzle (S4) while the setting dial S is adjusted to balance the pressure applied to the pressure sensor (P = P). The pressure sensor detects the differential pressure generated when the detection nozzle (S4) is released. When the work piece comes close to the detection nozzle, the back 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. 7

7 Air Catch Sensor Response Time Response time changes with detection distance and piping length. It is hardly influenced by the supply pressure and nozzle diameter (ø. to ø.). While all graphs assume a fixed set distance with changes in the detection distance, the upper charts show responses at various set values and the lower charts show responses at various piping lengths. If the detection distance is equal to the set value, the response becomes quicker as the set value becomes bigger or the piping length becomes shorter. -G Detection nozzle: ø.

17 Specific Product Precautions Be sure to read before handling. Refer to front matters 8 and for Safety Instructions and pages 87 to for Pressure Switch Precautions. Air Catch Sensor Operating Environment Warning. Do not operate in locations having an atmosphere of flammable, explosive or corrosive gases, which can result in fire, explosion or corrosion. The air catch sensor does not have an explosion proof rating.. 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, for the solenoid valve to IP, and that for the pressure gauge and the regulator to IP4. Take proper protection measures in an environment where water splashes, oil or spatters from welding may adhere to the product.. Since steel piping lacking flexibility is easily affected by moment loads or propagation of vibration, employ flexible tubing, etc., to prevent interactions of such factors. 4. Although CE accredited, this air catch sensor is not equipped with surge protection against lightning. Necessary countermeasures for possible lightning surge should be fitted to system components as required.. 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. 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. Piping. Piping equipment In the piping between the switch body and the detection nozzle, 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.. 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 µm 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 Precautions on Design Warning. Energized continuously Please consult with SMC if the product is to be energized continuously for long periods of time. 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 Pressure Source 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 E G

Also, conduct a periodic inspection at intervals of approximately months to use the product in its best condition. Warning. The adjustment knob must be handled manually. Use of tools may cause damage to the product.. Check the inlet and outlet pressure indications on the pressure gauge while setting. If the knob is turned to excess, it may cause internal parts to fracture.. Since products for. to. MPa settings come with a pressure gauge for. MPa, do not apply pressure exceeding. MPa. It may cause damage to the pressure gauge. Mounting and Adjustment. Unlock the knob before pressure adjustment and lock it again when the adjustment is over. Incorrect procedure may cause damage to the knob or lead to the outlet pressure fluctuation. Pull the adjustment knob to release the lock. An orange colored line is provided at the bottom of the adjustment handle for visual checking. Push the pressure regulation knob to engage the lock. If it does not lock easily, turn the knob slightly clockwise or counterclockwise until the orange colored line goes out of sight.. When the product is installed, leave a space of mm on the side of the valve guide (opposite to the knob) for maintenance and inspection. Manual Operation Warning How to operate manually Locking type (tool required) To open valve: Rotate to the right by using a flat head screwdriver. It will still hold open even when the driver removed. To close valve: Rotate to the left by to achieve the former closed position. Electrical operations should be undertaken when the valve is closed.
