Caution
1. Operating pressure range in the catalog is the values during ejector operation.
Secure the described value of the supplied air, taking a drop of the pressure
into consideration. Insufficient pressure, which does not satisfy the spec,
may cause abnormal noise, unstable performance and may negatively affect
sensors, bringing troubles at last.
2. Effective cross-section area of the air supply side needs to be three times as
large as effective cross-section area of the nozzle bore. When arranging piping
or selecting PISCO products, secure required effective cross-section area.
Insufficient supply pressure may be a cause to impair performance.
3. A Shorter distance of plumbing with a wider bore is preferable at vacuum
system side. A long plumbing with a small bore may result in slow response
time at the time of releasing work-piece as well as in failure to secure adequate
suction flow rate.
4. Plumb a vacuum switch and an ejector with vacuum switch at the end of
vacuum system as much as possible. A long distance between a vacuum
switch and a vacuum system end may increase plumbing resistance which
may lead to a high vacuum level at the sensor even when no suctioning and a
malfunction of vacuum switch. Make sure to evaluate the products in an actual
system.
5. Refer to “4. Instructions for Installing a fitting” and “5. Instructions for
Removing a fitting” under “Common Safety Instructions for Fittings” , when
installing or removing Fittings.
6. Refer to “Common Safety Instructions for Pressure Sensors” and “Detailed
Safety Instructions” for the handling of digital vacuum switch sensor.
7. Refer to “Common Safety Instructions for Mechanical Vacuum Sensor” for the
handling of mechanical vacuum switch.
8. The material of plastic filter cover for VG, VK, VJ, VZ and VX series is PCTG.
Avoid the adherence of Chemicals below to the products, and do not use them
under those chemical environments.
