Caution

To ensure your safety in using this instrument :

・Be sure to read the instruction manual carefully before using the instrument so that you

can use it properly.

Wrong use may result in failure of the instrument and lead to its damage and accident. This

manual should be kept in a proper place so that you can refer to it any time you need.

Ⅰ．PRECAUTIONS

△

！Warning

・Do not use the instrument where flammable gas is present.

The instrument is not explosion-proof. Do not use instruments in the circumstance where flammable gas is present. It

may cause explosion.

・Do not use the instrument at the place where corrosive gas is present.

The instrument is not corrosion resistance construction. Measuring corrosive gas may corrode the receiving element

and housing material of the instrument. It is expected that corrosive gas leaked out of the instrument will harm a

person.

・Do not apply the pressure to the instrument more than it can withstand.

The diaphragm and the retainer are broken and cause of injury or accident, etc. disaster if the pressure exceeding

withstanding pressure of the pressure receiving element is applied to the instrument. The case body and the

transparent cover of the instrument are broken and cause of injury or accident, etc. disaster if the pressure exceeding

withstanding pressure of the instrument body is applied to the instrument.

・The instrument is measurable for air and non-corrosive gas only.

The machine is exclusive use of dry air (90％RH or less). Using measuring the water or oil it may be damaged and

causes the accident.

・Avoid using where the instrument is subject to many vibration and impact.

Using the instrument where intensified vibration and impact may be damaged the instrument. It is expected that gas

leaks of the instrument which harms a parson.

・Do not exceed rated surrounding temperature, humidity and altitude in use.

Using the instrument by exceeding rated surrounding temperature and humidity and altitude it may be damaged and

cause the accident.

・Do not disassemble or reconstruct the instrument.

It may void the warranty.

・Do not exceed rated voltage in using

Using the instrument by exceeding rated voltage may cause fire or electric shock.

・Wire correctly.

Incorrect wiring may cause fire.

△

！Caution

・As to where to install and how to install this instrument, be sure to follow the instruction manual provided

so as to ensure a proper method.

・Use the instrument indoors.

・In case of not being installed in dry and well-kept clean locations, the instrument must be enclosed in box.

・Do not use organic solvent for cleaning.

Use a cloth soaked with water-diluted neutral detergent to wipe the surface of a product. Using of organic solvent

causes damage on the surface.

・Dropping the product.

Ⅳ．SETTING OF PRESSURE

1. Switch contact configuration

・Composition of contact of this instrument is as shown on the right.

・If the instrument is not applied by differential pressure we call such “normal condition”.

・At normal condition, the contact between 1(COM.) and 2(N.C.)

is closed, and between 1(COM.) and 3(N.O.) is open.

・With increase of differential pressure and reaching the

actuation pressure, the contact will be changed over ;

between 1(COM.) and 2(N.C.) is opened and between

1(COM.) and 3(N.O.) is closed.

2. Setting of upper limit/ lower limit

・When differential pressure applied to the instrument is

increased starting from zero and changes over the electric

contact from N.C. (normal close) to N.O. (normal open), the

pressure at this moment is called “actuation pressure”.

・When this differential pressure decreases from the pressure

higher than this actuation pressure activating electrical

contact and returning the contact from N.O. (normal open) to

N.C. (normal close), the pressure at this moment is called

“reset pressure”.

・There is certain difference between actuation pressure and reset pressure and this is called “dead band”.

・There are two types of the instrument. One is called “upper limit setting type”type (H) whose scale of

setting knob is adjusted on actuation pressure, the other is called “lower limit setting type”type (L)

which is adjusted on reset pressure.

・Depending on the purpose of use, choose the instrument either “upper limit setting type”or “lower limit setting type”

Please confirm the following table about the respective movement.

In case of 1-10 kPa range with set value 1 kPa. (dead band is 0.7 kPa)

Setting of scale Adjusting of scale Movement of contact

Upper limit

setting type Adjusted in activating pressure

When the differential pressure increases, the circuit is

closed between N.O. and COM. at 1 kPa.

Then as the differential pressure decreases, the circuit is

opened between N.O. and COM. at 0.3 kPa.

Lower limit

setting type Adjusted in reset pressure

When the differential pressure increases, the circuit is

closed between N.O. and COM. at 1.6 kPa.

Then as the differential pressure decreases, the circuit is

opened between N.O. and COM. at 1 kPa.

3．Setting the dial

Use the dial and pointer, when you set the “Activating pressure” or “Reset pressure”.

Set the "Activating pressure" for the upper limit setting.

Set the "Reset pressure" for the lower limit setting.

Set the tip of the pointer to the pressure you desire by knobbing the outer periphery of the dial to rotate the

dial. Turning the pointer from the lower side (anti-clockwise) is recommended to set accurately with good

reproducibility. Turning the pointer from the lower side (anti-clockwise) is recommended to set accurately

with good reproducibility.

4. Reset time

The reset time means the time needed for the differential pressure to decline to the reset pressure from the

activating pressure (i.e., the electrical contact is reset) when the differential pressure is sharply reduced to

zero. It is about three seconds at 20 Pa, and one second at more than 50 Pa for Manostar switches. (This

value is only for the instrument itself and does not include the effect of piping.) Therefore, a response

quicker than this value is not possible.

△

！

Caution

Do not turn the dial too much exceeding the upper bound or the lower bound of the scale.

It causes performance deterioration and the failure.

Ⅴ．ABOUT BUILT-IN SWITCH

1. Material of contact

The product has been plated a gold layer on the point of contact to get the contact reliability of the point on

the low electrical load.

The gold film is damaged when using by general use.

△

！

Caution

Once the product has been used for general load, it cannot be used for low electrical load.

2. About measured gas and contact failure

a) Corrosive gas

If the gas to be measured contains corrosive gases (nitric acid, hydrogen sulfide, sulfurous acid,

ammonia, chlorine, and so on), they may cause electrical contact failure or corrosion of internal

mechanism, which leads to malfunction of the switch. Do not use the switch for the gases containing

high humid air because in such gases, the arc generated by opening/ closing the contact produces nitric

acid, and it may also cause electrical contact failure or malfunction of switches.

b) Silicone gas

If the gas to be measured contains silicon produced from silicon (contained in oil, grease, filling agent,

and so on), the gas produced by arc, generates by opening/ closing the contact, accumulates on the

contact surface and causes contact failure. Take corrective measures such as the removal of the gas

source or arc suppression.

c) Dust and organic gas

The film can be made to the switch part by the composition of the gas. In addition, the dust contained in

the gas to be measured can adhere to the contact surface and be changed into carbide caused the

contact failure by the arc generated when the contact is opened or closed. Therefore, pay attention to

the measurement environment as well.

(Even with gold alloy contact, be careful about the dust.)

△

！

Caution

As the opening/ closing frequency of the contact increases, wear dust from the

contact increases. This wear dust accumulates between the contacts to increase the

contact resistance and causes the malfunction in the load circuit.

In particular, the surrounding where there exists continuous vibration and impact will be

most likely to cause contact failure due to worn powder.
