These instructions indicate the level of potential hazard by a label of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices. Caution : Operator error could result in injury or equipment damage. Warning : Operator error could result in serious injury or loss of life. Danger : In extreme conditions, there is a possible result of serious injury or loss of life. Note 1) ISO 4414: Pneumatic fluid power -- General Rules for Pneumatic Equipment Note 2) JIS B 8370: Pneumatic system axiom Warning 1. The compatibility of pneumatic equipment is the responsibility of the person who designs the pneumatic system or decides its specifications. Since the products specified here are used in various operating conditions, their compatibility for the specific pneumatic system must be based on specifications or after analysis and/or tests to meet your specific requirements. The expected performance and safety assurance will be the responsibility of the person who has determined the compatibility of the system. This person should continuously review the suitability of all items specified, referring to the latest catalog information with a view to giving due consideration to any possibility of equipment failure when configuring a system. 2. Only trained personnel should operate pneumatically operated machinery and equipment. Compressed air can be dangerous if handled incorrectly. Assembly, handling or repair of pneumatic systems should be performed by trained and experienced operators. 3. Do not service machinery/equipment or attempt to remove components until safety is confirmed. 1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe locked-out control positions. 2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system. 3. Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod, etc. 4. Contact SMC if the product is to be used in any of the following conditions: 1. Conditions and environments beyond the given specifications, or if product is used outdoors. 2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical equipment, food and beverages, recreation equipment, emergency stop circuits, clutch and brake circuits in press applications, or safety equipment. 3. An application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis. 16 3 Port Solenoid Valve/Common Precautions 1 Be sure to read before handling. Selection Design When an actuator, such as a cylinder, is to be driven using a valve, take appropriate measures to prevent potential danger caused by actuator operation. 2. Effect of back pressure when using a valve Use caution when valves are manifolded because actuator malfunction due to back-pressure may occur. 3. Holding pressure (including vacuum) Since valves are subject to air leakage, they cannot be used for applications such as holding pressure (including vacuum) in a pressure vessel. 4. The valve cannot be used as an emergency shutoff valve, etc. The valves presented in this catalog are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted. 5. Maintenance space The installation should allow sufficient space for maintenance activities (removal of valve, etc.). 6. Release of residual pressure Provide a residual pressure release function for maintenance purposes. 7. Vacuum applications When a valve is used for vacuum switching, take appropriate measures against the suction of external dust or other contaminants through vacuum pads and exhaust ports. 8. Ventilation When a valve is used inside a sealed control panel, etc., provide ventilation to prevent a pressure increase caused by exhausted air inside the control panel or temperature rise caused by the heat generated by the valve. Warning 1. Confirm the specification. The products presented in this catalog are designed only for use in compressed air systems (including vacuum). Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can cause damage or malfunction. (Refer to specifications.) Contact SMC when using a fluid other than compressed air (including vacuum). 2. Extended periods of continuous energization • Continuous energization of the valve for extended periods of time may have an adverse effect on the solenoid valve performance and the peripheral equipment due to temperature rises caused by the heat generation of the coil. Please consult SMC if valves will be continuously energized for extended periods of time or the energized period per day will be longer than the de-energized period. It is also possible to shorten the energization period by using valves of the N.O. (normally open) type. • When solenoid valves are mounted in a control panel, employ measures to radiate excess heat, so that temperatures remain within the valve specification range. Use special caution when three or more stations sequentially aligned on the manifold are continuously energized since this will cause a drastic temperature rise. Caution 1. Leakage voltage When using a resistor in Switching element parallel with the switching OFF element or using a C-R eleC R ment (surge voltage supPower Valve supply pressor) for protection of Leakage voltage the switching element, note that leakage voltage will increase due to leakage current flowing through the resistor or C-R element. Limit the amount of residual leakage voltage to the following value: 2% or less the rated voltage Leakage voltage Warning 1. Actuator drive 2. Surge voltage suppressor If a surge protection circuit contains diodes other than ordinary types of diodes such as Zener diodes or ZNRs, a residual voltage that is in proportion to the protective elements and the rated voltage will remain. Therefore, give consideration to surge voltage protection of the controller. 3. Low temperature operation Valve use is possible to temperature extremes to –10°C. Take appropriate measures to avoid freezing of drainage, moisture etc. 4. Mounting orientation Refer to the specifications. 17 3 Port Solenoid Valve/Common Precautions 2 Be sure to read before handling. Mounting Warning Lubrication Caution 1. If air leakage increases or equipment does not operate properly, stop operation. Check moutning conditions when air and power supplies are connected. Initial function and leakage tests should be performed after installation. 1. Lubrication 1) The valve has been lubricated for life at the manufacturer, and does not require further lubrication in service. 2) If a lubricant is applied in the system, use turbine oil class 1 (no additives), ISO VG32. 2. Instruction manual Mount and operate the product after reading the manual carefully and understanding its contents. Also keep the manual where it can be referred to as necessary. 3. Painting and coating Warnings or specifications printed or pasted on the product should not be erased, removed or covered up. Consult SMC if paint is to be applied to resinous parts, as this may have an adverse effect due to the paint solvent. Air Supply Warning 1. Use clean air. Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction. Caution Piping 1. Install air filters. Install air filters close to valves at their upstream side. A filtration degree of 5 µm or less should be selected. Caution 1. 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. 2. Screwing in fittings When screwing fittings into valves, tighten as follows. 1) M3, M5 (1) When installing SMC fittings, etc., follow the procedures below. After tightening by hand, tighten an additional 1/4 rotation for M3 and 1/6 rotation for M5 with a tool. However, when using a miniature fitting, tighten an additional 1/4 rotation with a tool after tightening by hand. Also, when there are 2 gaskets such as in case of a universal elbow or universal tee, tighten an additional 1/2 rotation. Note) If overtightened, threaded part may be broken or gasket deformed. If tightened insufficiently, thread part may be loosened. In either case, air leakage could occur. (2) When using a fitting brand other than SMC, follow the instruction by the manufacturer of the fittings. 2. Install an air dryer, after-cooler or water separator, etc. Air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer, after-cooler or water separator, etc. 3. If excessive carbon dust is generated, eliminate it by installing mist separators at the upstream side of valves. If excessive carbon dust is generated by the compressor, it may adhere to the inside of valves and cause malfunction. Refer to SMC’s “Best Pneumatics Vol. 4” catalog for compressed air quality. 3. Connection of piping to products When connecting piping to a product, refer to its instruction manual to avoid mistakes regarding the supply port, etc. Wiring Caution 1. Applied voltage When electric power is connected to a solenoid valve, be careful to apply the proper voltage. Improper voltage may cause malfunction or coil damage. 2. Confirm the connections. After completing the wiring, confirm that the connections are correct. 18 3 Port Solenoid Valve/Common Precautions 3 Be sure to read before handling. Maintenance Operating Environment Warning 1. Do not use in atmospheres where the valve is in direct contact with corrosive gases, chemicals, salt water, water or steam. 2. Do not use in an explosive atmosphere. 3. Do not use in locations subject to vibration or impact. Confirm the specifications in the main section of the catalog. 4. Use a protective cover, etc., to shield valves from direct sunlight. 5. Shield valves from radiated heat generated by nearby heat sources. 6. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc. 7. When solenoid valves are mounted in a control panel or are energized for extended periods of time, employ measures to radiate excess heat, so that temperatures remain within the valve specification range. Warning 1. Perform maintenance procedures as shown in the instruction manual. If handled improperly, malfunction or damage of machinery or equipment may occur. 2. Removal of equipment maintenance and supply/exhaust of compressed air When equipment is serviced, first confirm that measures are in place to prevent dropping of work pieces and run-away of equipment, etc. Then cut the supply pressure and power, and exhaust all compressed air from the system using its residual pressure release function. When the equipment is to be started again after remounting or replacement, first confirm that measures are in place to prevent lurching of actuators, etc., and then confirm that the equipment is operating normally. 3. Low frequency operation Valves should be switched at least once every 30 days to prevent malfunction. (Use caution regarding the air supply.) Caution 1. Drain flushing Remove drainage from air filters regularly. 2. Lubrication Once lubrication has been started, it must be continued. And use turbine oil Class 1 (no additives), VG32. If other lubricant oil is used, it may cause malfunction. Contact us for suggested turbine oil Class 2(with additive), VG32. 19 Series S070 /Specific Product Precautions 1 Be sure to read before handling. Refer to pages 16 through 19 for safety instructions, precautions. Caution Caution Valve mounting / Removal Screwing in M5/M3 thread 1. Base mounted with screws After tightening by hand, tighten an additional 1/4 rotation for M3 and 1/6 rotation for M5. Overtightening may cause bending of the thread or air leakage due to deformation of the gasket. Insufficient screwing may cause loosening of the thread or air leakage. With the base mounted type fixed with screws, confirm the installation of the gasket mounted on the body interface and fasten the dedicated mounting screws (AXT632-106-1) at an appropriate torque (0.10 to 0.14 Nm). (Fasten equally so that the valve will not tilt.) Applicable Tubing Size Stacking manifold Port 1 (SUP), 3 (EXH) 2 (OUT) Gasket Applicable tubing Recommended tubing TS0604/TU0604 ø6/ø4 TS0425/TU0425 ø4/ø2.5 TIUB01 ø3.18/ø2 Note) In case of a body ported single unit valve, the applicable tubing size is ø3.18/ø2 for all 1 (SUP), 2 (OUT), and 3 (EXH) ports. If fittings of a brand other than SMC are used, follow the specifications of the fittings to be mounted. Tubing installation (with barb fitting) 1) Using tubing cutters TK-1, 2, or 3, cut the tubing perpendicularly to the tubing axis while allowing for sufficient margin to the required length. 2. Base mounted with clips 1 Hook a flat head watchmakers screwdriver into the hole of the metal bracket and pull it approximately 1 mm in the direction indicated by the arrow. 2 Insert the solenoid valve from above. After confirming that the bottom surface of the solenoid valve contacts the top surface of the manifold, detach the flat head screwdriver from the mounting bracket while holding the solenoid valve body. (Before mounting, confirm the installation of the interface gasket on the solenoid valve body.) 2) Insert the tubing and push it all the way to the barb end. If the tubing is not installed securely to the end, problems such as leakage or disconnection of the tubing can occur. 3) When the tubing is inserted into the barb fitting, push it in the direction of the tubing axis to prevent excessive lateral loads being applied to the barb fitting. The built-in leaf spring returns the mounting bracket to its original position. (Then confirm that the end of the mounting bracket is aligned with the side of the manifold block. Refer to the figure below.) Similarly, to remove the valve, pull the mounting bracket and pull up the solenoid valve vertically. Use caution so that no excessive force is applied to the lead wire in mounting and removal. 2 4) To remove the tubing from the barb fitting, use caution so that no excessive lateral load will be applied to the barb fitting. When using a cutter to remove the tubing, sufficient care should be taken so as not to make any flaws on the barb fitting. 5) After tubing installation, avoid excessive loads, such as tensile, compressive, or bending strength, being applied to the tubing.

Refer to pages 16 through 19 for safety instructions, precautions. Caution Mounting 1. Solenoid valve fixing procedure (body ported single unit) When mounting a body ported type single unit valve, tighten the dedicated mounting screw (AXT632-106A-2) at an appropriate torque (0.05 to 0.07 Nm) to firmly secure the valve body. (Tighten equally so that the valve will not tilt.) If the coil is fixed, the coil joint may break due to application of an excessive load to the tubing body, for example, when the tubing is inserted. With a base mounted type solenoid valve also, use caution to avoid excessive loads. 2. Body ported manifold type 1 Remove the clip on the position where the station is to be added by pulling it in the direction indicated by the arrow. (Insert a flat head screwdriver in the recess indicated in the figure to remove the clip.) 2 Place the additional solenoid valve into the separation and insert the clip. Insert the clip until it fits in the groove on the body side. Secures the body. Solenoid cover (Metal) Body (resin) Clip Caution Adding and removing manifold stations 1. Base mounted stacking type 1 Remove the clip and metal joint from the position where the new station is to be mounted by pulling them in the directions indicated by the arrows. 2 Place the additional manifold block assembly and mount the metal joint and clip by reversing the assembly order. Securely insert the clip and the metal joint so that they will not protrude from the top and bottom surfaces respectively. Recess Groove Caution Vacuum application The clip is commonly used to secure the manifold block and fittings. 1 Clip An N.C. type valve pressurized at 1 (SUP) port can be used within the maximum operating pressure differential specified for the product. If the valve is to be used in the following applications, however, care should be taken about the piping ports, maximum operating pressure differential and allowable leakage. 1) Vacuum release application Use 3 (R) port for vacuum pressure and 1 (P) port for vacuum release pressure. The pressure differential between 3 (R) and 1 (P) is the maximum operating pressure differential for each type. 1 (P) Air supply (positive pressure) Metal joint 2 To remove the station, follow the same procedure for assembly and disassembly. 21 2 (A) Vacuum pad Vacuum supply 3 (R) 2) Vacuum retention Please consult SMC if the allowable leakage is limited when the valve is used for vacuum retention of a vessel, even within the low vacuum range (1.33 × 102 Pa or above).
