6. Operating Principle
As shown in diagram below, the bourdon tube transmits the position change
according to pressure change through a lever to open or close the micro switch.
7. Contact Point Working Type and Connection
1) Upper limit contact type (HIGH ALARM)
There is one contact point to turn the circuit ON if the pressure is above the setting
or OFF if it is below the setting.
2) Lower limit contact type (LOW ALARM)
There is one contact point to turn the circuit ON if the pressure is below the setting
or OFF if it is above the setting.

4) Two upper limit contacts (HIGH & HIHIGH ALARM)
There are two contacts combining two upper limit contact types that operate
independently.
5) Two lower limit contacts (LOW & LOLOW ALARM)
There are two contacts in combination of two lower limit contact types that operate
independently.
8. How to Set

1) Upper limit type (H)
It will be turned ON if the pressure on the rise reaches the set value of the indicator hand.
Adjust with the indicator hand to a new setting by moving it from the upper limit to
lower limit.
2) Lower limit type (L)
It will be turned ON if the decreasing pressure reaches the set value of the indicator hand.
Adjust with the indicator hand to a new setting by moving it from the lower limit to
upper limit.
9. Maintenance and Operation
1) The commercial pressure shall be below 75% of the max graduation.
2) Do not impose a pressure beyond the allowable limit.
3) Avoid sudden pressure surge or drop.
4) If there is a risk of pulsation or impact pressure, install overpressure protection device
like dampener or gauge protector.
5) Do not grease the operation parts in the pressure gauge.
6) The regular inspection shall be made once or twice in 6 months to check contact operation.

7) If the indication instrument makes a big error, remove it from the product for inspection.
It may have been caused by wear, corrosion, external shock, vibration, or shock of a part.
In this case, you must remove, adjust, or exchange the part.
8) The standard rated current shall follow 4. 7) but it may be different when the product is
equipped with a special micro software. Please, add some allowance to the rated current
written in this product, considering the inrush current.
9) The micro switch contact resistance is destined to increase gradually as per the elapsed time.
Under minute load in Si environment, in particular, SiO2 which is accompanied by contact
operation may deposit on the contact to increase the contact resistance abruptly, so you
must ventilate or move to a clean environment. When you use the product for control
sequence input, there is more possibility of contact disorder, so please use an AC 110/220V
buffer relay between the contact and the sequence.
10) Before you open or close the cover for pressure gauge repair or inspection, be sure to shut
off the power.
Malfunctioning of the switch may ignite the explosive gas in the gauge.
10. Use
1) When installing a gauge for the first time, it is recommended to use the valve so it can be
removed or controlled easlily.
2) It is required to find out followings before using the gauge.
- Pulsation exist? If yes, then use Dampner.
- Vibration exist? If yes, then filled the gauge with oil or use oil filled gauge.
- Is ambient temperature high? If yes, then use capillary type gauge.
3) Before using the gauge, make sure zero point is properly adjusted.
4) On the connection screw, use teflon tape or gasket to install the gauge firmly.
5) When installation is finished, slowly open the valve to find out the pointer is correctly
indicating current pressure.

11. Installation
1) Install in a place devoid of moisture, vibration, dust or corrosive gas.
2) Avoid areas that might exceed the temperature ranges specified in this manual.
3) Make sure to protect from lightning or steam.
4) Avoid areas with direct sun light.
5) Use M5 nuts and bolts to mount on a panel or wall using the mounting holes.
If mounting brackets are used, make sure it is installed securely.
6) Inlet tube should be flexible not to strain the pressure indicating switch.
7) Please use specified wrench.
12. Wiring
1) Do not stress the main body.
2) Please use proper PVC insulated wire or captire cable.
3) Use M4 crimps to connect terminals for solid contacts.
4) Please confirm contact types in the diagrams before connecting terminals.
5) In case of conduit type, use waterproof sealing fittings.
6) In case of cable gland type, use waterproof cable glands.
