External vacuum controller

Transcription

1 By newly adding pressure adjusting function to blow-off flow adjusting function, it enables to prevent works from being blown away. A relief mechanism built into the blow-off circuit which breaks the vacuum (extra pressure is relieved) realizes shorter vacuum release time. A variety of features allows this vacuum unit to respond to diverse needs. (ejector unit, external vacuum controller). The pipe lead-out direction of concentrated pipings of manifold-type, two types are available-front lead-out type and rear lead-out type; choice depends on the place of installation. Supply valves are available in three different types: double solenoid type (retention type), normal close type and normal open type (always creating vacuum). Among the three types, double solenoid type (retention type) is optimal for applications where the vacuum is generated for a long period of time. LED vacuum switches allow for clearer visual recognition. Two types of vacuum switches are available, two switch outputs or analog & one switch output, with selection depending on the desired application. For wiring, a connector wire is adopted to enhance the ease of designing the wiring layout. Four standard nozzle diameters are available: 05, 07, 10 and 12.

Warnings: 1. For the operation of the valve, make certain that the leakage current is less than 1mA. Leakage current larger than that may cause malfunction. 2. This acuum Generator with vacuum holding function permits some vacuum leakage, so provide an appropriate safety means where vacuum must be held for long time. 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 isco. 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. A model with retention type air supply valve (refer to as double solenoid type), JA, must confirm position of change valve by sending signal to or by manually operation of pilot solenoid valve when re-supplying pilot air after shut down once or initial setting because the change valve is placed at neutral position. Cautions : 1. In order to avoid disconnection and/or damage to the connectors, do not allow the pilot valve and vacuum switch lead wires to be pulled or bent. 2. In respect to manifold specifications, performance deterioration or adverse effects may possibly be produced on the vacuum ports of other stations depending on the number of manifold series used and/or combinations of installed units. Discretion is therefore to be used in this respect. Consult us if problems arise. 3. Compressed air contains a variety of foreign matter (such as water, oxidized oils, and mineral tar among others). Since foreign matter substantially reduces the performance of this equipment, air quality should be enhanced by dehumidification via after-coolers or dryers. 4. Do not use lubricators. 5. Since pipe rust cause malfunctions, a filter 5µm or better should be used. 6. Do not use this equipment near corrosive and/or flammable gases. Do not use this equipment for the handling of fluids. 7. Do not activate blow-off solenoid valve when a vacuum has been generated. 8. When replacing vacuum port cartridge joints, first remove any foreign matter clinging to them and the surrounding areas, then firmly insert pins into joints. 9. When replacing supply port joint blocks, confirm that their packing is in place, then remove foreign matter from surrounding areas and tighten screws according to the prescribed torque 0.27 ~ 0.3N m. 10. As the series number of manifolds increases, trouble, such as the lowering of vacuum performance due to an insufficient supply of air and/or insuffient exhaust port capacity, exhaust air flowing directly into vacuum ports and others such problems may possibly be encountered. Consult us on this matter, since simultaneous activation-allowable series numbers differ according to each unit's vacuum performance. 157

9 Be sure to read the following instructions before selecting and using the ISCO 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 0.1Ma (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. rovide 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. rovide 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. lease contact ISCO for information. 136

10 This Safety Instructions aim to prevent injuries to human bodies and damage to properties by requiring proper use of ISCO devices. Also the relevant requirements of ISO 4414 and JIS B8370 must be observed. ISO 4414: neumatic 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. Danger : Failure to heed the warning of apparent danger may result in death or serious injuries. Warning : Failure to heed the warning of conditionally dangerous situations may result in death or serious injuries. Caution : Failure to heed the warning of conditionally dangerous situations may result in minor or not too serious injuries or damage to properties. Warning : 1. Make a selection of pneumatic equipment. (1) Well knowledgeable and experienced persons such as a pneumatic system designer or who is in charge of deciding specification should select pneumatic equipment. (2) The applicable conditions of the products in this catalogue are diverse. Therefore, judge the conformity of systems with required analysis or tests by system designers or persons who is in charge of deciding specifications. The guarantee of initial performance and safety of the system is on responsibility of the person who decides specifications. Hereafter, examine all the specification with updated products catalogues and technical documents in order to avoid malfunctions of equipment, and then develop systems. 2. Handle pneumatic equipment with enough knowledge and experience. (1) Mishandling of compressed air is dangerous. Conduct assembly, operation and maintenance of devises with pneumatic equipment by persons with enough knowledge and experience. 3. Do not operate and remove the equipment until safety is confirmed. (1) Conduct inspection and maintenance of equipment after confirming fail-proof measures of work pieces or runaway-proof device are properly working. (2) When removing equipment, make sure that above safety measures are conducted. Then, stop air supply and electric source of equipment making sure the pressure inside the system is zero before removing equipment. When re-activate equipment, make sure safety measures against fly-out are taken and re-activate equipment with care. * Safety Instructions are subject to change without advance notice. 13

11 ISCO 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 ISCO devices: (1) Use under conditions not specified for the device (2) Use in any outdoor environment Use in locations where the device is exposed to excessive vibration or shocks Use in locations where the device is exposed to any corrosive gas, inflammable gas, chemicals, seawater, or vapor. * Certain ISCO 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 ISCO 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 (140 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. lease conduct maintenance after confirming following points. (1) Make sure that maintenance is safe for all the systems involving ISCO products. (2) When re-activate equipment after maintenance, make sure safety measures against fly-out are taken and re-activate equipment with care. lease 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 ISCO 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 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.

(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. 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) ush 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. With the joint whose piping direction will not change after tightening, make adjustment within the recommended range of tightening torques. Table 3.
