Detailed Safety Instructions
Warning
1.All screws must be tightened to the correct torque referring to the instructions. The tightening torques, for the mounting of the product is given in "How to fix body" and for the filter cover is given in "How to replace Filter Elements". Failure to tighten to the correct torque may result in air leaks, product detachment and damage to parts of the product.
Frequently Asked Questions for External Vacuum Controller 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.
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."
