1. Safety Precautions

WARNING

●

Do not use this product in safety circuits such as those designed to protect human workers.

●

This product does not employ an explosion-proof construction. Do not use it in the presence of flammable gasses, liquids, or powders.

●

This is a direct current power supply type sensor. Application of an alternating current may result in explosion or fire.

3. Pipe Connections

You can select from one of two pressure ports: one on the back of the sensor that can accommodate a pipe leading directly away from the back of the sensor, and one on the side of the sensor to accommodate a pipe leading away from the sensor at a right angle.

1) The pressure port is 1/8 of NPT. Commercially available air pressure joints and nipples can be used with the port. When attaching the joint, use a wrench to hold the pressure port in place as illustrated below.

2) Attach the included valve plug to the pressure port not being used.

• Do not use a torque in excess of 10 Nm when tightening the joint. Doing so may damage the joint.

• Apply sealing tape when attaching the joint in order to prevent air leaks.

4. Mounting Brackets (option)

Dedicated mounting hardware is available for the sensor, allowing it to be installed in a range of locations.

5. Connection Method and Diagrams

Insert the included connector-tipped cable into the sensor’s connector. Position the connector so that the side of the connector where the metallic contacts are visible is facing up.

7. Detection Mode Operation

■ General-purpose mode (F-1)

This mode allows the user to configure 2 detection points. Control output 1: Turns ON when pressure exceeds setting P1. Control output 2: Turns ON when pressure exceeds setting P2.

OFF ON OFF

Output 1

*Hysteresis is a standard 0.5% of F.S. when operating in general-pur-

pose mode and application modes 1 and 2. During focus mode operation, it is 0.2% of F.S.

■ Variable hysteresis mode (F-2)

Two detection points may be user-configured, and hysteresis for both may also be set. Control output 1

: Turns ON when pressure exceeds setting P1. Turns OFF

when pressure drops the selected hysteresis amount below P1.

Control output 2:

Turns ON when pressure exceeds setting P2. Turns OFF

when pressure drops the selected hysteresis amount below P2.

■ Window mode (F-3)

The user may select a pair of upper (Hi) and lower (Lo) thresholds, and the sensor turns OFF when the pressure falls outside of the resulting range. *Control output 1 is a standard 0.5% of F.S. During focus mode opera-

tion, it has a hysteresis of 0.2% of F.S., and control output 2 has a hysteresis of 0.

6. Precautions for Safe Use

Follow these guidelines. Failure to do so may result in product damage.

CAUTION

■

Connections

Input/output circuit

●

Always ground the frame ground terminal when using an off-the-shelf switching regulator.

●

Use separate conduits for power line and high voltage lines, since use of a common conduit may result in device malfunction.

●

Improper wiring may result in the device becoming excessively hot or in device damage.

■

Other

●

Do not use this sensor with corrosive gasses or liquids.

●

Do not insert objects such as wire into the pressure insertion area. Doing so may result in the device failing to operate properly due to damage to the pressure-sensitive elements.

●

Do not use sharp-tipped objects to press the setting keys.

■ Application mode 1 (A-1)

This detection mode is optimum for use in suction detection applications. Recommended sensor heads: AP-C30K/C30KP/C31K/C31KP Control output 1:
