5 Before using the PISCO device, be sure to read the "Safety Instructions", "Common Safety Instructions for Products Listed in This Manual" on page 13 to 15 and "Common Safety Instructions for Solenoid Valve" on page 108. Warning : 1. Where the Solenoid Valve is used with vibration of 49m/s 2 or below, install it in such a way that the direction of vibration is perpendicular to the spool valve. * See the following illustration Cautions : 1. When the valves are used as Valve Manifold, back pressure can cause malfunction of the actuator (single acting cylinder, etc.) In such a case, provide a check valve to the exhaust port. 2. Do not use a 3-position valve for middle position stop of the cylinder that requires accuracy. Compressiveness of air may not allow accuracy in stop position. Also, the valve permits leakage, so that the stop position may not remain constant for a long time. 3. Do not give excessive tension or bending to the individual plug-in connector (cable). Disconnection or damage to the connector may result. 4. The cartridge joint can be disconnected by removing the lock pin. During use, however, make certain that the lock pin is properly in place. 5. Read the manual carefully for proper installation and removal of valves. Also, keep the manual at hand. 6. In case of wiring Sub-D connector, Individual plug-in Connector and Flat Cable, please refer to P.339 for Electric Circuit. (Single manifold controls two different air supply pressure) 1. Partition position confirmation is made by checking the position of the triangle on the side of the unit (see Fig. 1). The right side, including the triangle-marked manifold block, is for P2 supply pressure. The left side is for P1 supply pressure. (In the case of Fig. 1. St.1 to St.2 are for P1 and St.3 to St.8 are for P2) 2. Please note that alteration of the partition position cannot be accepted after the ex-works. 3. Available intake and exhaust block configuration is A type (on both sides) only. Fig. 1 L side St. 1 St. 2 St. 3 St. 4 R side Partition position identification mark (triangle mark) 1. Be sure to clamp the screw with specified torque. 2. Do not place any item whose weight exceeds the max. movable load. 3. Avoid fitting where vibriations are extremely strong. (Max. 9.8m/s 2 ) 132

7 Be sure to read the following instructions before selecting and using the PISCO devices. Also read the detailed instructions for individual series. Warnings: 1. When installing the piping, carry out flushing on both the compressed air side and the cylinder side and provide an air filter (nominal filtration rating: 5µm or below) on the upstream side near the valve. Drainage or dirt, if left unremoved, may cause malfunction. 2. Do not allow excessively lubricated air or super-drying air to flow. Degradation due to dust or malfunction due to oil may result. 3. Do not use these device in locations where they can be exposed to water drops, oil drops, dust, etc. The valves are neither drip-proof, so that malfunction may result. 4. Do not use these device in locations with inflammable or explosive gas, fluid or atmosphere. Fire or explosion may occur. 5. Do not use these devices in atmosphere or gas containing corrosive substances. Trouble may occur eventually. 6. Avoid the use of these device where they are exposed to excessive vibration or shocks. Such use may cause malfunction or trouble. 7. For operation of the valves, make certain that the leakage current is 1mA or below. Leakage current may cause malfunction. 8. A coil generates heat when electric current is provided to a valve in a state of following ~. It may lead to shorten the product life or to operational malfunction by the heat. Additionally, it may cause burns or influence the peripheral equipments adversely. About such applications in the state of following ~, please consult Pisco.. Long continuous electrical power is supplied to the valve for more than about 2 hours.. High cycle operation of valve.. Even with the intermittent power supply to valve, if a total energization time of a day exceeds a total non energization time of the day. Cautions : 1. These valves are designed to accommodate some leakage, so do not use them in applications that permit no leakage. 2. Do not use the valves for large-flow air blowing. As the structure is an internal pilot type, the drop of internal pressure may lead to malfunction. 3. Manual operation of the valve can operate the actuator connected to it. Therefore operate after confirming safety. 4. Consult PISCO on applications where power is continuously supplied to the valve for a long time. 5. Be sure to turn off power before installing the wiring. Also pay special attention to wire colors in wiring. 6. You can use these valves without lubrication. When you lubricate, however, use Turbine Oil Class 1 (ISO VG 32). Once you start the habit of lubrication, do not stop it. Otherwise the initial lubricant will be lost, thus causing malfunction. 7. Before wiring, check the ports of the valve by the marking on the body. 8. For maintenance or checks, turn off power, stop air supply and make certain that the pressure inside the piping has become zero. With the 3-position all port block type, watch out for the air remaining between valve and cylinder. 9. With the manifold having a silencer, clogging of the element raises the resistance to exhaust, thus lowering the performance of the system as a whole. Therefore conduct periodic maintenance and checks. 108

8 This Safety Instructions aim to prevent injuries to human bodies and damage to properties by requiring proper use of PISCO devices. Also the relevant requirements of ISO 44 and JIS B8370 must be observed. ISO 44: Pneumatic fluid power Recomendations for the application of equipment to transmission and control systems. JIS B 8370: General standards for pneumatic systems Safety instructions are classified into "Danger", "Warning" and "Caution", depending on the degree of danger or damage involved when the safety instructions are not complied with in handling the equipment.

9 PISCO products are designed and manufactured for use with general industrial machinery and equipment. Therefore be sure to observe the following safety instructions: Danger Warning : 1. Avoid the following uses for PISCO devices: (1) Use under conditions not specified for the device (2) Use in any outdoor environment (3) Use in locations where the device is exposed to excessive vibration or shocks (4) Use in locations where the device is exposed to any corrosive gas, inflammable gas, chemicals, seawater, or vapor. * Certain PISCO devices, however, can be used in environments as described above. Therefore check on the specifications for the use of individual devices. 2. Do not disassemble or remodel the PISCO devices in such a way as may affect the basic structure, performance or function of them. 3. Never touch the release ring of the Quick-Fitting Joint when there is pressure working on it. Touching may release the ring, which in turn may cause the tube to fall out. 4. Avoid too frequent switching of air pressure. Otherwise the device body may heat up to cause burns on you. 5. Do not allow tension, twist or bending forces to act on the joints. Undue forces may damage the joint body. 6. For applications in which the threaded side or the tube connection side is subject to vibration, use Rotary Joints, High Rotary Joints or Multi-Circuit Rotary Blocks only. Swinging or rotation may damage the joint body. 7. For applications with hot water of 60 C (0 F) or above or thermal oil, use no other joints than Die Temperature Control Fitting, Tube Fitting Stainless SUS316, Tube Fitting Stainless SUS316 Compression Fitting, and All Brass Compression Fitting. Heat or hydolysis may damage the joint body. 8. For applications in which the scattering of static electricity or charging must be prevented, use no other joints than EG Joints. Static electricity may cause system malfunction or trouble. 9. Never use joint other than Tube Fitting Spatter or Tube Fitting Brass where they are exposed to spatter. Otherwise can cause fire. 10. Carry out maintenance and checks of equipment only after turning power off, shutting fluid off and making certain that the pressure in the piping has dropped to zero. Please conduct maintenance after confirming following points. (1) Make sure that maintenance is safe for all the systems involving PISCO products. (2) When re-activate equipment after maintenance, make sure safety measures against fly-out are taken and re-activate equipment with care. (3) Please secure space for maintenance when the circuit is designed. 11. When the fluid is admitted to the equipment and if there is a possibility to cause damage to it due to leakage, conduct safety measures such as protect cover beforehand. Caution : 1. Do not use PISCO devices with the following equipment: (1) Equipment used for the sustenance or control of people's health or lives (2) Equipment used for the movement or transport of people (3) Equipment used specifically to ensure safety : 1. In installing the piping, be sure to remove dust or drainage from within the piping. Dust or drainage left unremoved may enter other equipment, thus causing troubles. 2. When using an ultrasoft tube to connect to a Quick-Fitting Joint, be sure to use an insert ring in the bore of the tube. Otherwise the tube may fall out to cause leakage. 3. When you use tubes of brands other than ours, be sure to confirm that the outside diameter of the tubes satisfies the tolerance specified Table 1. Table 1. Tube O.D.

10 4. Cautions on the fitting of tube (1) Make certain that the end of the tube is cut at right angles, the tube surface is free from flaws, and the tube is not deformed into an ellipse. (2) When fitting a tube, insert the tube to the tube end completely as drawings shown below to prevent leakage. Tube end : GOOD Release-ring : NG Tube Lock claws Sealing: Elastic-sleeve Tube is not inserted fully to tube end. (3) On completion of fitting, make certain that the tube does not come out at your pulling. 5. Cautions on the release of tube (1) Before releasing the tube, make certain that the pressure inside the tube is zero. (2) Push the release ring fully inside and pull out the tube. Unless you push it completely in, the tube may not come out and scrapings of tube may be left inside the joint. 6. Cautions on the installation of joint body (1) When installing the joint body, tighten it with a proper tool, using the outside or inside hexagon. (2) In tightening the screw, use the tightening torque recommended in Table 3. Use of a torque higher than the recommended level may damage thread or deform gasket, thus causing leaks. Use of a torque lower than the recommended level may cause loose screw and leakage. (3) With the joint whose piping direction will not change after tightening, make adjustment within the recommended range of tightening torques. Table 3.
