sensor, use the sensor by tiling it slightly upwards to avoid wrong operation.

Specular face

If a specular body is present in the

Specular face

background, wrong operation may be caused due to a small change in the angle of the background body. In that case, install the sensor at an inclination and confirm the operation with the actual sensing object. Take care that there is a non-detactable

area right in front of the sensor.

Sensing object

Do not make the sensor detect an object in this direction because it may cause unstable operation.

CAUTIONS

Make sure that the power supply is off while wiring and adjusting.

Take care that wrong wiring will damage the sensor.

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 product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Cable extension is possible up to total 100m

or more, cable. However, in

order to reduce noise, make the wiring as short as possible. Do not run the wires together with high-

voltage lines or po the same raceway. This can ca

wer lines or put them in

use malfunction due to induction. Take care that the sensor is not directly

exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the Do not use during the initial transient time

(50ms) after the power supply is switched on. This sensor is suitable for indoor use only.

A mechanical structure is employed for the

distance adjuster of this product. Take care not to drop the product. Do not use this sensor in places having excessive

vapor, dust, etc., or where it may come in direct contact with water, or corrosive gas. Take care that the sensor does not come in

direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. This sensor cannot be used in an

environment containing inflammable or explosive gases. Never disassemble or modify the sensor.

When this product is used, be sure to carry out the distance adjustment.

Since the distance adjuster of this sensor is a 5-turn adjuster, when the point and is adjusted as explained in the table below, there may be more than 1 turn between the point and . Therefore, make sure to remember the turns of both points to find the optimum position.

Be sure to wire the sensing mode selection input (Pink/2) before distance adjustment. If the wiring is done after the distance adjustment, the sensing area is changed.

Turn the distance adjuster gradually and light-

ly with a screwdriver (please arrange separately). In order to protect itself, the distance adjuster idles if turned fully. If the adjuster is idled when distance adjustment is done, carry out the adjustment again.

Description

Turn the distance adjuster fully counterclockwise to the minimum sensing range position. prox., 20mm approx. for CX-441غ

Place an object at the required distance from the sensor, turn the distance adjuster gradually clockwise, and find out point where the sensor changes to the detecting condition.

Remove the object, turn the adjuster clockwise further until the sensor goes into the detecting state again. Once it has entered, turn the adjuster backward a little until the sensor returns to the undetecting condition. That tion is designated as point When the sensor does not go into the detecting condition even if the adjuster is fully turned clockwise, the position where the adjuster was fully turned is regarded as the point .
