2 CAUTIONS

DP2 series is designed for use with non-corrosive gas. It cannot be used for liquid or corrosive gas.

●This product has been developed / produced for industrial use only.

●Use within the rated pressure range.

●Do not apply pressure exceeding the pressure withstandability value. The diaphragm will get damaged and correct operation shall not be maintained.

●Make sure to carry out the wiring in the power supply off condition.

●Take care that wrong wiring will damage the sensor.

●Verify that the supply voltage variation is within the rating.

●If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

●In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground

●Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.

●Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

●This product is suitable for indoor use only.

●Avoid use of standard type, flat type and light weight type of sensor in places where steam and dust is excessive.

●Take care that the sensor does not come in contact with water, oil, grease, or organic solvents, such as, thinner, etc.

●Do not insert wires, etc, into the pressure port. The diaphragm will get damaged and correct operation shall not be maintained.

●Do not operate the keys with pointed or sharp objects.

●Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.

●Extension up to total 100m is possible with 0.3mm2, or more, cable. However, in case of using this product as a CE Marking conformity product, the power wire connected to this product must be within 10m.

3SETTING OF PRESSURE LEAD DIRECTION AND PIPING

Standard type

● Setting of pressure lead direction

The pressure lead direction can be changed by dismantling the pressure port attachment and changing the

mounting direction. The

tightening torque of the hexagon-socket-head

bolt (length 9mm or less) should be 0.29N m or less.

Main body

Hexagonsocket- head bolts

Pressure ports

Note: Please make sure to close any unused pressure port with the hexagon-socket-head plug supplied as accessory.

● Piping

When connecting a hexagon-socket-head plug or coupling to the pressure port, hold the hexagonal part of the pressure port with a 12mm spanner and make sure that the

tightening torque is 9.8N m or less. Also, in order to prevent any leakage, wind a sealing tape on the coupling when connecting.

However, sealing tape is not required for North American type using NPTF 1 8 coupling. (Sealing tape is required if NPT 1 8 coupling is used.)

Flat type, Light weight type

● Setting of pressure lead direction

The pressure lead direction can be changed by dismantling the pressure port attachment and changing the mounting direction. The tightening torque of the hexagon-socket-head bolt (length 9mm or less) should be 0.29N m or less.

type: 10mm)	spanner and
make sure that the tightening		16mm
torque is 9.8N m or less		(light weight type: 10mm)
(Light weight type: 1.47N m		spanner

or less). Also, in order to prevent any leakage, wind a sealing tape on the coupling when connecting.

IP67 type

● Piping for pressure measurement inlet port

When connecting a coupling to the pressure measurement inlet port, hold the pressure port attachment with a spanner and make sure that the tightening torque is 9.8N m or less. Also, in order to prevent any leakage, wind a sealing tape on the coupling when connecting.

● Piping for atmospheric pressure inlet port

If there is a possibility of water entering into the

sensor enclosure through the atmospheric pressure

inlet port, connect a tube to the atmospheric pressure inlet port through

a M5 coupling and extend the other end of the tube

to a safe place. In this case, ensure that this end

of the tube does not get clogged.

● Fitting of front cover

Insert the bosses on the front cover into the guide holes at the bottom of the pressure port attachment,

and push in the direction of the Hook arrow to fit the hook.

When removing the front cover, release the hook first.

Guide holes

4 MOUNTING OF STANDARD TYPE SENSOR

●A sensor mounting bracket MS-DPX and MS-DPX-4 (optional) may be used.

When mounting the sensor with the sensor mounting bracket, etc., the tightening torque should be 1.2N m or less.

●The pressure unit can be selected as per customer's requirement.

●In case of positive pressure type, the pressure unit can be changed from International System of Units (SI) 'kPa' or 'MPa' to 'kgf/cm2', 'bar' or 'psi'. In case of vacuum pressure type, the pressure unit can be changed from International System of Units (SI) 'kPa' to 'kgf/cm2', 'bar', 'psi', 'mmHg' or 'inHg'.

When the pressure unit is changed, the set values and the measured value are automatically converted.
