SWITCHING FUNCTION
■ TECHNICAL DESCRIPTION
□ Pressure connections
A or B : For excessive pressure
C or D : For negative pressure
Use yellow scale wheel to adjust the spring to the switching pressure.
The pressure in the controlled line has an effect on the diaphragm which opens and closes
against the spring force of the micro switch.
■ APPLICATION
It can be applied in various ways depending on the installation sequence in accordance with the other devices,
and it must be performed by the following tests.
- Excessive pressure test
: If connecting excess pressure to connection A or B, it must be ventilated via connection C or D.
- Negative pressure test
: If connecting negative pressure to connection C or D, it must be ventilated via connection A or B.
- Differential pressure test
: If connecting the higher pressure to connection A or B, remaining connections must be plugged.
■ INSTALLATION POSITION
[ Standard installation position ]
Install the standard position as shown.
[Figure1] is available but the switching point is made in other place.
The installation of other positions including [Figure2], [Figure3] is impossible.

■ ATTENTION
All installation/maintenance work must be carried out by skilled staff. Always check that the system is gas-tight after installation.
Failure to follow this manual may result in dangerous situations or damage to the product.
■ TECHNICAL DESCRIPTION
- This product is a mechanical pressure control without auxiliary power.
- Diaphragm type pressure switch can be used in a variety of process lines.
■ INSTALLATION
1. Warning
- Select a product based on the operating pressure depending on the model specifications table in this manual before installation.
- The gas and sources of electricity supply must be shut off before installation.
- Make sure that the pipeline is free from impurities and vibration-free before installation.
- Function and holding tests must be carried out After installation.
2. Installation Location
- Make sure to install the standard position as shown in the manual.
- If the installation differs from the standard position, the pressure switch will malfunction.
■ ADJUSTMENT
1. Remove the transparent cover by meaning of across screwdriver.
2. Turn the yellow range scale knob to achieve the nominal pressure worth.
3. The differential pressure acts on the micro switch via the diaphragm against the force of the adjusting spring.
■ Standards and specifications of this product are subjective to change without prior notice for improved performance.
