Instruction Manual

1. Safety Precautions

●

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.

●

Installation on a DIN track

1) Align the hook on the bottom of the sensor to the DIN track

●

Installation using the included mounting bracket (AP-

V41A(P)). as shown below. Lower the sensor in the direction indicated by

➁while pressing on the sensor

in the direction indicated by ➀.

2) When removing the sensor, lift

the sensor as shown in ➂ while pushing on the sensor in the direction indicated by ➀.

4. Additional Amplifier installation

A single AP-V41A(P) sensor can be expanded with the following number of slave units:

* The same applies to the PNP type of the

3) Insert the 2 hooks on each slave unit into the groove on the APV41A(P) until they click into place.

4) Attach an end unit to each side of the chain of amp units. Sandwich the amps securely between the end units and use a Phillips head screwdriver to tighten the screws on the top of the end units (2 screws for each unit).

5. 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 on the front of the amp unit. To remove the connector, depress the connector lock and pull it out.

■ 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.

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.

●

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

●

Sensor head connectors that have been pressure-connected once cannot be used again.

■

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.

8. About Sensor Head Installation

Common Do not subject the case to pressure sufficient to deform

AP-41(M) • Use a torque of 0.3 N 43 • 44 for the sensor head conduits.

AP-48 Use a torque of 5 N

its shape during installation.

•

m or lower to tighten the screws

•

m or lower to tighten the screws for the sensor head conduits. Take care that no foreign objects enter the sensor when opening one of the pressure ports to atmospheric air. Take care not to bend the pressure ports. Connect the “High” port to the high-pressure side of the system and the “Low” port to the low-pressure side.

9. 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.

■ 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 uses a hysteresis of 0.5% of F.S., while control out-

put 2 uses a hysteresis of 0.

■ 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:

Suction pressure detection. Turns ON when pressure exceeds setting P1.

Control output 2:

Detection and confirmation of vacuum burst pressure detection (or vacuum ultimate pressure). Turns ON when the pressure falls below setting P2.

Zero shift: Shifts the zero point immediately after setting the zero

shift timer once zero shift input is received. P1: Pressure setting for control output 1. T1: Zero shift timer setting (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

: Leak pressure detection.

Turns ON when pressure falls below setting P1.

*Output only when zero shift input is ON. Control output 2:

Window comparator output for detection of fill pressure.

Turns OFF when pressure falls outside the range deter-

mined by upper (HI) and lower (Lo) thresholds. 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.

*Hysteresis during general-purpose mode and application mode 1/2

operation is 0.5% of F.S. during standard and high-speed mode operation, and is 0.1% of F.S. during high-resolution mode operation.
