Characteristics
• Perfect for use in an IC chip loader, IC handlers and other semiconductor manufacturing devices.
• Limited space can be utilized.
Small size and lightweight vacuum generator & external vacuum controller.
In particular, the height is lowered for small space use.
●Stand alone type ●Manifold type
• High speed, yet stable respose is realized. (ON/OFF=Max. 5msec)
Direct operated solenoid valve is used for the main valve.
• Small workpiece is removed gently at vacuum break with blow-off.
Air supply port for blow-off is independent. Therefore, not only conventional ow adjustment but also using external regulator easily make the ne adjustment of blow-off
air.
●Circuit Diagram
• Common supply port type is also available.
Air supply port for vacuum generation and blow-off are common.

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
Vacuum" on page 136.
DetailedSafetyInstructions
Warnings
Cautions
[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 ① to ③ conditions. It may lead to shorten the product life or operational malfunction by heat. Additionally, it may
cause burns on worker or inuence a peripheral device adversely. In such cases, please consult with Pisco.
① long continuous energization about 2 or more hours
② high cycle operation
③ 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 specication must be avoided. It may cause valve malfunction.
[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 dehumidication by the after
cooler and drier, then improve of air quality.
3. Never supply lubricated air.
4. Rust and inow of foreign particles in piping cause malfunction and performance drop. Therefore, install a lter (ltration capacity: max. 5µm) just before the air supply port.
On top of it, Prior-to-use and periodic ushing is recommended.
5. Do not use the devises in the atmosphere of corrosive and ammable gas. In addition, do not use the gas as uid admitted. Since this product is not explosion-proof type, it
may cause re 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 ttings for air supply (PS, PV) or vacuum (V) port, be sure to remove extraneous matter from the seal and x the fastening pin rmly in place.
2. The performance of silencer tted ejector unit and lter tted 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. Insufcient effective sectional area may cause performance
drop in characteristics such as suction ow and blow-off airow.
2. In selecting the piping to the supply (PS, PV) port, save piping bore and length for enough effective sectional area. Insufcient effective sectional area may cause performance
drop due to short supply of compressed air and vacuum ow.
3. This product is not equipped with a vacuum lter. Therefore, use PISCO vacuum lter at the same time. If the lter 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 lter: 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 ow rate and etc.) and/or air consumption (vacuum characteristics) of ejector and other such problems may possibly be encountered.
Consult PISCO sales ofce on this matter.
5. Although Vacuum 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 ofce.

CommonSafetyInstructionsforVacuumSeries
Be sure to read the following instructions before selecting and using the PISCO devices. Also read the detailed instructions for individual series.
: 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.
Warnings
: 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).
Cautions
* There are chemicals other than listed above that can not be used. Please contact PISCO for information.
