CAUTIONS

Make sure that the power supply is off while wiring.

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. Do not run the wires together with high-voltage

lines or power lines or put them in the same raceway. This can cause malfunction due to induction. Extension up to total 100m, is possible with

, or more, cable. However, in order to re-

0.3mm duce noise, make the wiring as short as possible. Do not use during the initial transient time

(50ms) after the power supply is switched on. Take care that the sensor is not directly exposed

to fluorescent lamp from a rapid-starter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance. Avoid dust, dirt, and steam. Do not use it in

places having excessive vapor, dust, etc., or where it may come in direct contact with corrosive gas. Take care that the sensor does not come in di-

rect contact with water, oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline. Make sure that stress by forcible bend or pulling

is not applied directly to the sensor cable joint. Since the cable end is not waterproof, do not

use the sensor in the application where water may seep in from the cable end. When connecting the mating cable to the

connector type sensor, the tightening torque should be 0.4N㨯morless.

MOUNTING

٨ The tightening torque should be 0.8N㨯mor

less.

Sensing object

Do not make the sensordetectanobject in this direction because it may cause unstable operation.

٨٨When detecting a specular object (aluminum or

copper foil, etc.) or an object having a glossy surface or coating, please take care that there are cases when the object may not be detected due to a small change in angle, wrinkles on the object surface, etc. When a specular body is present below the sensor, use the sensor by tiling it slightly upwards to avoid wrong operation.

٨٨If a specular body is present in the 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. Some object may produce the dead zone right in front of the sensor.

AUTOMATIC INTERFERENCE PREVENTION FUNCTION

٨ EQ-30 series is incorporated with automatic

interference prevention function. Up to two sets of sensors can be installed close together.

Close mounting of two sensors

STABILITY INDICATOR

Since the EQ-30 series uses a 2-segment photodiode as its receiving element, and sensing is done based on the difference in the incident beam angle of the reflected beam from the sensing object, the output and the operation indicator operate according to the object distance. Further, the stability indicator shows the margin of the incident light intensity and not that of the object distance. Hence, the distance at which it lights up/off depends on the object reflectivity and is not at all related to the output operation. Do not use the sensor when the stability indicator is off (unstable light received condition), since the sensing will be unstable.

٨ Adjusting procedure

Step

Turn the distance adjuster fully counterclockwise to the minimum sensing range

position of 0.2m approx.

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 light received condition.

Remove the object, turn the distance adjuster further counterclockwise, and find out point where the sensor changes to the light received condition again with only the background.

When the sensor does not go to the light received condition even if the adjuster is fully turned clockwise, point is this extreme point in the range.

The optimum position to stably detect ob-

jects is the center point between and .

Note: Use the accessory adjuster screwdriver to turn the distance

adjuster slowly. Turning with excessive force will cause damage the adjuster.

gradually clockwise, and find out point

Remove the object from the near position, and place the object for Far (Main) sensing at the sensing position. Turn the Near (Sub) distance adjuster further clockwise, and find out point where the sensor changes to the light received con-

dition again with only the background.

Notes: 1)2)Use the accessory adjuster screwdriver to turn the dis-

tance adjuster slowly. Turning with excessive force will cause damage the adjuster. The Far (Main) distance adjustment should be done before the Near (Sub) distance adjustment. Take care that the Near (Sub) setting distance changes with change in the Far (Main) setting distance.
