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 Rc (PT). 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.

Hold in place
with wrench
(12mm).

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.

*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-C30W/C30WP/C31W/C31WP

Control output 2:

Zero shift: The zero point is shifted immediately after the zero

P1: Pressure setting for control output 1.
T1: Zero shift timer setting (ms) < Variable between 0 and 1,999 ms>
P2: Pressure setting for control output 2.
*P2 is unrelated to zero shift and is always based on the current ambi-

ent pressure.

■ Application mode 2 (A-2)

This mode is optimum for use in leak test applications.
Recommended sensor head: AP-C33W/C33WP
Control output 1

Control output 2:

P1: Pressure setting for control output 1.
Hi: Upper threshold setting for control output 2.
Lo: Lower threshold setting for control output 2.
*The Hi and Lo values are unrelated to zero shift and are always based

on the current ambient pressure.
