Thank you for purchasing PISCO
product. Please be sure to read this
User's Manual before using this item in
order to make sure the safety. Please
keep this manual handy with care, so that
you can refer to it whenever necessary.
PISCO products catalogues include
Common Safety Instructions for PISCO
products and Vacuum equipment.
Please conrm the Safety Instructions as
well.
External Vacuum Controller VIP
User's Manual
HIR0060-01
●Warning
[Product 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 devices with solvent or water. Solvent use may cause breakage of resin parts and malfunction by
port clogs.
[Product 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. Each screw should be tightened with a proper tightening torque. The recommended tightening torque of the product is
shown at "How to x External Vacuum Controller VIP" and the one of solenoid valve is shown at "How to replace the lter
element for atmosphere inlet". Improper tightening causes air leakage, drop of product, and damage of product.
[Product application]
1. For the operation of the valve, make certain that the leakage current is less than 1mA. Leakage current exceeding it may
cause malfunction.
2. Avoid applying excessive vibration or shocks to the devises. It may damage devises and lead to malfunction of solenoid
valve.
4. The coil generates heat when the solenoid valve is energized in the following ①to ③conditions. The heat may possibly
lead to shorter operating life or system failure of the product. There are also possibilities of bad inuence to peripherals or
of burn injury by heat.
If the product is energized in the following conditions, please consult with Pisco in such a case.
①Continuous energizing for about 2 hours or more.
②High cycle energizing.
③The total energizing time of a day exceeds the total non-energizing time even if it is intermittent energizing.
●Caution
[Product Handling]
1 .Do not use the equipment other than the service pressure range. Operating it other than the specied pressure range may
cause damage or deformation.
2. Do not pull or bend lead wires of solenoid valve or vacuum switch excessively. Doing so may result in disconnection of lead
wires or connector components broken.
3. Compressed air contains plenty of drain (Water, oxidized oil, tar and foreign particles etc.). Since drain may cause
performance drop, conduct air dehumidication by after-cooler and drier to improve air quality.
4. Never supply lubricated air.
5. Rust in piping and inow of foreign particles cause malfunction and performance drop. Therefore, install an air lter (ltration
capacity: max. 5μm) just before the air supply port. On top of it, Prior-to-use and periodical ushing is recommended.
6. Do not use the product in locations where it is exposed to water drops, oil drops, dust, etc. Since this product is not drip or
dust proof model, it may cause breakage or performance drop.
7. The lead wires of solenoid valve is polarized. Therefore, the solenoid valve is not activated by wiring with wrong polarity.
[Product maintenance]
1. The performance of product may deteriorate due to dust trapped in the lter elements. Therefore, we recommend frequent
cleaning or replacing the elements at just the right time.
[Product application]
1. In selecting the piping to the vacuum (V) port, select piping bore and length to ensure saving enough effective cross
sectional area. Insufcient effective sectional area may cause performance drop in characteristics such as suction ow and
vacuum release airow.
2. In selecting the piping to the supply (PS,PV) port, select piping bore and length to ensure saving enough effective sectional
area. Insufcient 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 solenoid valve malfunction or air leakage.
(Recommended lter: VFU series and VFJ series)
4. As the series number of manifolds increases, there is limitation on the allowable simultaneous activation series depending
on the condition of the vacuum supply (supply port size, piping length, vacuum 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 ofce for such application.
5. Vacuum breaking (blow-off) air may flow around to vacuum port of non-operating units even though the each unit has
individual vent exhaust. Pleasa consult PISCO if such ow creates problem.

(1). Tube insertion
Simply insert a tubing into the tube
end of fitting of Vacuum unit VIP.
The lock-claws automatically x the
tubing, and elastic sleeve seals the
tube surrounding. Please refer to
''2. Cautions on the fitting of tube''
in Common Safety Instructions for
Quick-Fitting Joint of general catalogue.
(2). Tube Release
In case of releasing the tube, push
the release ring. The lock-claws
open and the tube can be released.
Before releasing the tube, make
certain to turn off the air supply.
Use M3 screws to x the unit with the two mounting holes by the recommended tightening torque of 0.3-0.5N.m. Use of a
torque other than the recommended level may cause dropout or breakage of the products. (Please refer to the following
drawing for the dimension of hole pitch).
Turning the airflow adjustment needle clockwise decreases the flow rate of blow-off air, while turning the needle
counterclockwise increases the ow.
● Warning
1. When removing tubing from the unit, be sure to turn off the air supply and discharge residual air pressure completely.
2. Install the piping by checking the location of air supply port, vacuum port and exhaust port in the catalogue.
● Caution
1. Do not apply excessive vibration or shock to the unit. Using it in such condition can lead to malfunctions and/or errors.
● Caution
1. Make sure to use an appropriate at-blade screwdriver for adjusting blow-off airow.
2. This product incorporates an internal spring as the needle rotation lock. Therefore, a locknut is not equipped on the
needle. Do not use a wrench on the hexagonal part. It may cause breakage.
● Caution
1. Do not pull or bend lead wire, connector cable, and sensor cable excessively or avoid excessive repeated motion. Such
use may cause the disconnection of wire/cable or breakage of the product.
Replacement of lter elements (Model: VN013B19) of external vacuum controller is conducted by removing the xing screws
of vacuum supply valve by an appropriate Philips screwdriver. After new lter element has been put in place, conrm that lter
packing for the vacuum supply solenoid valve is placed in right position, and x the valve with the removed screws rmly at a
tightening torque of 0.15-0.2N.m.
● Caution
1. After replacing the lter element, be sure to x the valve by xing screws rmly with a tightening torque of 0.15 ~ 0.2N·m.
