Detailed Safety Instructions
Warning
1.When using double piloted valve type under a vibration, install the vacuum generaor placing the switchover valve (main valve) at a right angle to the direction of vibration
2.Tighten screws with appropriate tightening torque referring to the digital catalog. Improper tightening may cause an air leakage, a falling off of the product or damages to the product.
3.For the double-piloted valve type, the switchover valve is in the state of neutral when the supply of both pilot air to the switchover valve for vacuum generation is stopped, or at the beginning of use after shipment. When resupplying pilot air, be sure to input a signal to the pilot valve or manually operate to position the switching valve in the required state before using it
Frequently Asked Questions for Vacuum Generator, Multitasking / Manifold Series
VUS011-NW and FVXS-DW-1 are not the type of the product itself, but the type of "sensor" installed in the product. The official model code of the product is laser marked (or labeled) on the body. FVUS011-** is the sensor for Vacuum Generator VK, and FVXS-** is the sensor for Vacuum Generator VX (External Vacuum Controller VXP / VXPT).
The type of our vacuum generator complex type (External Vacuum Controller) starts with "V". (VG ..., VQ ... etc.)
The sensor model code may start with FV ... and may be written as [PRESSURE SWITCH].
The sensor model code is described only in the specifications with a sensor.
"Tube exhaust type" which does not exhaust air and installing a silencer are recommended.
However, be aware when smooth plumbing without resistance is not carried out such as with too long tube to exhaust, it becomes resistance to exhaust and impair the vacuum degree.
The vacuum characteristic of each type is different.
【H type】
High-vacuum type (Rated supply pressure* : 0.5Mpa)
【L type】
Large-flow type (Rated supply pressure* : 0.5Mpa)
【E type】
High-vacuum at low air pressure supply type (Rated supply pressure* : 0.35Mpa)
For high-vacuum, H type, to provide large-suction flow, L type, and to save supply air, E type is recommended respectively. (Details of final vacuum and suction flow are determined by choice of the nozzle diameter.

What is rated supply pressure?
Rated supply pressure guarantees product performance under the designated conditions and is also the supply pressure, which a vacuum generator supplies, of basis to design and use. The ultimate vacuum reaches to the max. around the rated supply pressure value.
The following graph shows the case of H type. The ultimate vacuum is the highest near 0.5Mpa. (ex. Simple vacuum generator VHH07 (Nozzle dia. 07: ø0.7mm)
When the product performance is reduced, the followings can be the causes.
Please check the product in terms of these points.
1) Check the supply air
Please check if the supply air flow volume and the air pressure are sufficient.
2) Check the nozzle clogging
When foreign substances are clogged in the nozzle, do flushing to clean it.
3)Clogging of the vacuum filter on sucking side or the silencer on the exhaust side.
When a filter is clogged, replace it with new one.
Rated supply pressure of Vacuum Generator is designated according to the vacuum characteristics (H, L and E type) respectively.
This rated supply pressure is required air pressure to start operating Vacuum Generator. When the supply air pressure is under the rated supply pressure, abnormal sound may be caused by some particular supply pressure.
During abnormal sound is being generated, the vacuum characteristics may become unstable and cause troubles such as influencing pressure detection by a sensor. Reset the product to keep the supply pressure satisfying the rated supply pressure in that case. ( Product spec. is the value in operation of Vacuum Generator.)
Both types indicate the valve position when the valve is unactuated. (normal position).
Normally closed type (N. C.)
Normal position is closed, covering a valve . When the valve is actuated, or electricity flows, the valve opens.
Normally open type (N. O.)
Normal position is open, uncovering a valve. When the valve is actuated, or electricity flows, the valve closes.
With the valve unactuated, the entrance leads to the exit.
There are two ways of measuring pressure, absolute pressure and gauge pressure.
Absolute pressure
Absolute pressure is zero-referenced against a perfect vacuum.
It is commonly used to measure flow rate.
When indicated, "abs" is inserted following the unit, for example 10 kPa abs.
Gauge pressure
Gauge pressure is zero-referenced against ambient air pressure.
It indicate how much pressure per １cm2 is against the ambient air pressure. It is commonly used for indication of manometer. When the pressure is over the ambient air pressure, it is called "positive pressure" and when it is under the ambient air pressure, it is called "negative pressure."
