7 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 " on page 136. Warnings [Products Handling] 1. Do not step onto or place objects on the devices. These may cause falling accident, fall of devices, injuries from falling and malfunctions from device breakage. 2. Do not wash or paint the devises with solvent. Solvent or water use may cause breakage of resin parts and malfunction by port clogs. [Products maintenance] 1. Carry out maintenance and checks of equipment only after turning power off, shutting air off and making certain that the residual pressure in the piping has dropped to zero. 2. When installing wiring and piping, be sure to switch off the power and make sure there is no miswiring and mispiping before applying power and air. 3. In tightening the screw, use the recommended tightening torque. The recommended tightening torque for installation of VN & VNP is 0.3 ~ 0.35N m (0.22 ~ 0.26lbf ft) for M3 thread, and for installation of pilot solenoid valve is 0.15 ~ 0.2N m (0.11 ~ 0.15lbf ft). Use of a torque other than the recommended level may cause air leakage, dropout or breakage of the products. [Products application] 1. For the operation of the solenoid valve, make certain that the leakage current is less than 1mA. Leakage current larger than that may cause malfunction. 2. Avoid applying excessive vibration or shocks to the devises. It may damage devises and lead to malfunction of solenoid valve. 3. Coil of pilot solenoid valve generates heat with the following to conditions. It may lead to shorten the product life or operational malfunction by heat. Additionally, it may cause burns on worker or influence a peripheral device adversely. In such cases, please consult with Pisco. long continuous energization about 2 or more hours high cycle operation When, even as for the intermittent energization, the total energization time is longer than the total of non-energization time within a day. 4. Long continuous power supply to the valve may raise the temperature of the coil. Heat may cause burns or affect the surrounding equipment adversely. Consult PISCO about such applications. 5. Current limit circuit is adopted for the solenoid valve. It features the current drop when the coil is energized and retains current. Therefore, the use in the location having vibration or shock greater than the specification must be avoided. It may cause valve malfunction. Voltage at retention (power consumption: 0.6W) Electric current at start-up (power consumption: 2.2W) about 20msec Cautions Electric current and voltage waveform at valve excitation [Products Handling] 1. Do not pull or bend lead wires of solenoid valve or vacuum switch excessively. Doing so may result in lead wires or connector components broken. 2. Compressed air contains plenty of drain (Water, oxidized oil, tar and foreign particles etc.). Since drain may cause performance drop, conduct air dehumidification by the after cooler and drier, then improve of air quality. 3. Never supply lubricated air. 4. Rust and inflow of foreign particles in piping cause malfunction and performance drop. Therefore, install a filter (filtration capacity: max. 5µm) just before the air supply port. On top of it, Prior-to-use and periodic flushing is recommended. 5. Do not use the devises in the atmosphere of corrosive and flammable gas. In addition, do not use the gas as fluid admitted. Since this product is not explosion-proof type, it may cause fire and explosion. 6. Do not use the devises in locations where they can be exposed to water drops, oil drops, dust, etc. Since this product is not drip or dust proof type, they may cause breakage or performance drop. 7. The lead wire of solenoid valve is polarized. Therefore, the solenoid valve is not activated by wrong polarity. [Products maintenance] 1. When replacing cartridge fittings for air supply (PS, PV) or vacuum (V) port, be sure to remove extraneous matter from the seal and fix the fastening pin firmly in place. 2. The performance of silencer fitted ejector unit and filter fitted external vacuum controller may deteriorate due to dust trapped in the elements. Therefore, we recommend cleaning well or replacing the elements freguently at just the right time. [Products application] 1. In selecting the piping to the vacuum (V) port, save piping bore and length for enough effective sectional area. Insufficient effective sectional area may cause performance drop in characteristics such as suction flow and blow-off airflow. 2. In selecting the piping to the supply (PS, PV) port, save piping bore and length for enough effective sectional area. Insufficient effective sectional area may cause performance drop due to short supply of compressed air and vacuum flow. 3. This product is not equipped with a vacuum filter. Therefore, use PISCO vacuum filter at the same time. If the filter is not used, dust or other particles are accumulated inside the product and cause vacuum performance drop (vacuum generator) and solenoid valve malfunction such as air leakage. (vacuum generator and external vacuum controller) (Recommended filter: VFU series and VFJ series) 4. As the series number of manifolds increases, there is limitation on the simultaneous activation-allowable series depends on the condition of the air supply (supply port size, piping length, regulator processing flow rate and etc.) and/or air consumption (vacuum characteristics) of ejector and other such problems may possibly be encountered. Consult PISCO sales office on this matter. 5. Although Generator VN series manifold type is the open to air exhaust by individual unit, the exhaust air from a vacuum-generating unit or blow-off air may be exhausted to the vacuum port of other non-activating units. If this is a matter, please consult PISCO sales office. 196

10 Be sure to read the following instructions before selecting and using the PISCO devices. Also read the detailed instructions for individual series. Warnings: 1. Where there is a danger of work dropping, provide some drop prevention means to assure safety. 2. Avoid use where there are constant pressures of 0.1MPa (14.5psi) or above in the vacuum circuit. Since the vacuum devices are not of explosion-proof structure, such use may cause damage to the device bodies. 3. Watch out for the drop of vacuum due to faulty air supply or power supply. Reduced suction may cause the drop of work. Therefore, take an adequate protective measure. 4. Where two or more pads are used with a single ejector in vacuum circuit, defective suction of one pad may cause the drop of vacuum at the other pad(s). 5. Avoid such usage as may stop up the exhaust port of the ejector or raise exhaust resistance. Such careless usage may cause the loss or drop of vacuum. 6. Do not use the vacuum devices in an atmosphere containing corrosive gas, inflammable gas, explosive gas, chemicals, seawater or vapor. Never allow the vacuum system to suck in such substances. 7. Provide a protective cover where the equipment is exposed to sunshine. 8. Carry out periodic maintenance and checks of the silencer element of the ejector and the filter element of the vacuum filter. A clogged element may cause performance drop or trouble. 9. Replace the element after gaining a full knowledge of the element of the vacuum generator. 10. Install the piping by checking the ports of the ejector in the manual and by the marking on the body. Mistaken piping may cause damage to the device body. 11. Use clean supplying air free from drainage or dirt for ejector. Also, never supply lubricated air. Impurities or oil contained in compressed air may cause malfunction or performance drop. 12. Do not give excessive tension or bending to lead wire. Disconnection may result. 13. Tighten the lock nut, in any, on the product securely with your hand and not with any tool. Tightening with a tool may cause damage to the lock nut or the device body. Also, incomplete tightening may cause a loose lock nut or inaccurate initial setting. 14. Do not subject the product with a rotatable resin body to forcible swinging or rotation. Damage to the resin body or leakage may result. 15. Do not flow excessive air or dried air. Rubber degradation or oil may cause malfunctions. 16. Do not use the equipment in locations where they can be exposed to water drops, oil drops, dust, etc. They may cause malfunctions. In case they are used under the conditions, prepare protect measures. 17. Do not use the equipment in locations with inflammable or explosive gas, fluid or atmosphere. Fire or explosion may occur. 18. Do not use the equipment in atmosphere of corrosive gas, chemicals, seawater, water and steam. These applications may cause trouble to equipment. 19. Do not wash or paint products with water or solvent. 20. Avoid the use of equipment where they are exposed to excessive vibration or shocks. Such use may cause malfunction or trouble. Cautions : 1. The specified supply pressure to the ejector is that during ejector operation. Secure the specified level in consideration of pressure drop. If the specified level is not met, then the ejector may emit an abnormal noise at certain supply pressures and become unstable, affecting the sensor and other parts adversely. 2. In selecting the piping and equipment, take into account that the effective sectional area on the supply pressure side of the ejector should be about three times the sectional area of the nozzle diameter. Inadequate supply flow may result in performance drop. 3. Provide the vacuum-side piping as short as possible and with the bore as large as possible. If the piping is long or the bore is small, the responce time at suction or release may become longer and the necessary suction flow may not be achieved. 4. Connect the vacuum switch or the ejector with vacuum switch as close to the end of the vacuum piping as possible. With long distance between the vacuum switch and the end of vacuum piping, the flow resistance may become large and the vacuum at the sensor may be high even during the non-suction interval. This will cause malfunction of the vacuum switch. 5. In handling the joints, observe the instructions in "Common Safety Instructions for Quick-Fitting Joints" (For installation and removal of the screwed-on type, refer to "4. Notes on Installation" and "5. Notes on Removal".) 6. In handling the electronic vacuum switch (sensor), observe the "Common Safety Instructions" and "Detailed Safety Instructions" for the pressure sensors and the pressures sensors with digital indication of the control sereis. 7. In handling the mechanical vacuum switch (sensor), observe the "Common Safety Instructions for mechanical vacuum switches". 8. The filter clear cover is polycarbonate, so avoid use in an atmosphere or location containing chemicals (see table below). Names of Chemicals Thinner Carbon tetrachloride Choloroform Acetate Aniline Cyclohexane Trichloroethylene Suphuric acid Lactic acid Water soluble cutting oil (alkaline) * There are chemicals other than listed above that can not be used. Please contact PISCO for information. 136

(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.
