Wiring

  • Make sure that the power supply is off while wiring.
  • 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 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.
  • Incorrect wiring will cause problems with operation.

Connection

  • Do not apply stress directly to the connection cable leader or to the connector.

Connection

Conditions in use for CE conformity

  • The DP-100 series is a CE conformity product complying with EMC Directive. The harmonized standard with regard to immunity that applies to this product is EN 61000-6-2 and the following condition must be met to conform to that standard.

[Condition]
・The line to connect with this sensor should be less than 30 m 98.425 ft.

Mounting

  • MS-DP1-1 / MS-DP1-5 sensor mounting brackets are available separately, and it should be used for mounting. When tightening the sensor to the sensor mounting bracket, use a tightening torque of 0.5 N·m or less.

Mounting MS-DP1-1 / MS-DP1-5

  • The MS-DP1-2 panel mounting bracket (optional) and the MS-DP1-3 front protection cover (optional) are also available.

The MS-DP1-2 panel mounting bracket (optional) and the MS-DP1-3 front protection cover (optional)

  • The MS-DP1-4 panel mounting bracket is available when switching from the DP2 / DP3 series.

The MS-DP1-4 panel mounting bracket

  • An conversion bushing is available for when using the DP-10□-M(-P) short pressure port type. It can be used to switch between this model and the DP2 / DP3 series. When connecting to the pressure port, use a tightening torque of 1.0 N・m or less.

Conversion bushing MS-DP1-7

  • The MS-DP1-F□ flat attachment is available for when using the DP-10□-M short pressure port type. If using the MS-DP1-F□ flat attachment (optional), install by following the procedures given below.

(1) Decide the direction of this product to mount with the sensor.

Decide the direction of this product to mount with the sensor.
Note: It is not possible to mount this product such that the pressure port faces upward.

(2) Mount this product with the M3 female threads of the sensor by using the attached M3 (length 8 mm 0.315 in) screws. The tightening torque should be 0.5 N・m or less.

Mount this product with the M3 female threads of the sensor by using the attached M3 (length 8 mm 0.315 in) screws.

(3) Mount this product with the mounting surface by using the attached M4 (length 20 mm 0.787 in) screws. The tightening torque should be 1.2 N・m or less.

Mount this product with the mounting surface by using the attached M4 (length 20 mm 0.787 in) screws.
Note: Take care that if the cable with connector is sticking out of the side groove of this product when mounting, the cable may disconnected.

Piping

  • If connecting a commercially-available coupling to the pressure port, attach a 12 mm 0.472 in spanner (14 mm 0.551 in spanner for DP-100-E type) to the hexagonal section of the pressure port to secure it, and tighten at a torque of 9.8 N・m or less. If it is tightened using excessive torque, it may damage the coupling or the pressure port. In addition, wrap sealing tape around the coupling when connecting it to prevent leaks.

  • If connecting a commercially-available joint to the pressure port of the DP-10□-M(-P), hold the main unit in your hand to steady it, and tighten to a torque of 1.0 N・m or less. If it is tightened to an excessive torque, the joint or the main unit may become damaged.
  • If connecting a commercially-available joint to the pressure port of the MS-DP1-7, tighten to a torque of 9.8 N・m or less.

  • The tightening torque should be 1 N・m or less when connecting a coupling to the pressure port of MS-DP1-FM.

  • When connecting the coupling to the pressure port of MS-DP1-FR/FE/FN, hold the pressure port with a 14 mm 0.551 in spanner and make sure that the tightening torque is 9.8 N・m or less.
    In addition, in order to prevent any leakage, wind a sealing tape on the coupling when connecting.

Note: Do not tighten the pressure port by holding the product with the spanner. It may cause the product breakage.

Flat attachment

  • Make sure to mount MS-DP1-F□ with the sensor properly. If it is not mounted properly, air leakage may occur.
  • Take care that the excessive mounting and dismounting of this product may cause deterioration of the O-ring.
  • If you touch the O-ring of MS-DP1-F□, or any scratch or dust, etc. is attached to it, air leakage may occur and the sensing performance may deteriorate. Take sufficient care when using and storing MS-DP1-F□.

Others

  • This product has been developed / produced for industrial use.
  • 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.
  • Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.
  • Avoid dust, dirt, and steam.
  • Take care that the sensor does not come in direct 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.
