3. Sensor Head Installation

1) Cut the cable to an appropriate length and strip away about 25 mm of the outermost insulation.

Note: It is not necessary to

remove insulation from the core wires.

2) Insert the cables after aligning them with the colors on the seal on top of the connector body.

3) Press together the body and the connector cover into which the cables were inserted to make a connection (use a pair of pliers or similar tool to press them together).

4) Insert the sensor head connector into the hole of the amp unit. To remove the connector, depress the connector lock and pull it out.

* Do not reuse sensor head

connectors that have already been pressure-connected.

8. 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.

6. 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.

Input/output circuit (AP-C40) Input/output circuit (AP-C40P)

*Hysteresis when operating in general-purpose mode and application

modes 1 and 2 is 0.5% of F.S. in the standard and high-speed modes. During focus mode operation, it is 0.1% 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 0.5% of F.S. during standard and high-speed

operation, it has a hysteresis of 0.1% of F.S. in the focus mode, and control output 2 has a hysteresis of 0.

7. Precautions for Safe Use

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

Connections

●

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 caused by noise .

●

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

Notice about CE marking

●

Attach the ferrite core (OP-87505) if you extend a sensor head cable/ amplifier power cable to 3 m or more to use. (Attachment position: within 100 mm from the amplifier unit of a power cable, Number of turns: 2)

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 heads: AP-41/41M/44 Control output 1:

Control output 2:

Zero shift: Shifts the zero point immediately after setting 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 head: AP-43 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.

Suction pressure detection. Turns ON when pressure exceeds setting P1. Detection of vacuum burst pressure (or confirmation of vacuum arrival pressure). Turns ON when the pressure falls below setting P2. May be set during focus mode operation, although there are restrictions on the setting range.

shift timer once zero shift input is received.

: Leak pressure detection.

Turns ON when pressure falls below setting P1. *Output only when receiving zero shift input. Window comparator output for detection of fill pressure. Turns OFF when pressure falls outside the range determined by upper (Hi) and lower (Lo) thresholds. Fill pressure values are displayed with the center pressure as 0 during focus mode operation.
