3 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.

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.

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.

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 sensing performance.

If an external surge voltage exceeding 4kV (DC-voltage: 1kV) is impressed, the internal circuit will be damaged, and a surge suppressing element should be used.

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.

4 MOUNTING

The tightening torque should be 0.8N m or less.

(Optional)

Care must be taken regarding the sensor mounting direction with respect to the object's direction of movement.

Sensing object

Sensing object

Sensing object

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

When 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.

Specular	Specular
face	face

Tilt

If 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.

This product is not easily affected by the reflected light intensity since this sensor is the adjustable range reflective type. When the reflected light intensity is remarkably low, the sensing range may be affected. In that case, mount the sensor, while checking light-up of the stable indicator (green).

Mounting screws of the terminal cover and display cover should certainly be tightened to maintain the water tight rating, however, the tightening torque of the screws should be of 0.3 to 0.5N m.

5 WIRING CONNECTIONS

Check all wiring before applying power since incorrect wiring may damage the internal circuit.

Also, carefully tighten the terminal screws so that the wires of adjacent terminals do not touch.

The mounting hole for screw the terminal cover fixing

	inclines 70 degrees to the	Screw for terminal

	in the figure below.
	To avoid damaging this
	product or a screw, take	70
	care when tightening or	Screwdriver
	loosening a screw.

To maintain a watertight performance, the cable should have an outer diameter between 9 to 11mm with a smooth covering material that allows the accessory conduit connector to be securely tightened, however, the tightening torque of the screw should be of 1.5 to 2.0N m.

Note: When assembling the conduit connector, take care of the direction of the gland packing.

Furthermore, in order to maintain a watertight performance, fit the gland packing such that the seating surface of the gland packing contacts the packing holder part of the terminal cover

If pressure terminals are to be used, affix the connected pressure terminals to a terminal (M3.5 screw).

	Detection-ON mode is obtained when the
	switch is turned fully clockwise.
	Detection-OFF mode is obtained when the
	switch is turned fully counterclockwise.

Note: Turn the operation mode switch gradually and lightly with the attached screwdriver. If the distance adjuster is over turned or pressed heavily, it may be damaged.

10 DISTANCE ADJUSTMENT

For DC-voltage type, be sure to set the BGS/FGS function before distance adjustment. If the setting is done after the distance adjustment, the sensing area is changed.

Turn the distance adjuster gradually and lightly with a screwdriver (please arrange separately). In order to protect itself, the distance adjuster idles if turned fully.

	Step	Description	Distance
			adjuster

Turn the distance adjuster fully counterclockwise to the minimum sensing range position. (0.2m approx.)

Turn fully

Please 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 clockwise, 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.

	Turn the distance adjuster fully clockwise to

			Turn fully

In the state where the sensor detects the background, turn the distance adjuster gradually counterclockwise, and find out point where the sensor changes to the undetecting condition.

Place an object at the required distance from the sensor, turn the adjuster counterclockwise further until the sensor goes into the undetecting condition again. Once it has entered, turn the adjuster backward a little until the sensor returns to the detecting condition. That position is designated as point .

When the sensor does not go into the undetecting condition even if the adjuster is fully turned counterclockwise, the position where the adjuster was fully turned is regarded as the point .

Optimum The optimum position to stably detect objects position is the center point between and .

11 STABILITY INDICATOR

Since the EQ-500 series use 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 (orange) operate according to the object distance.

Further, the stability indicator (green) shows the margin to the setting distance.

	TIMER FUNCTION (EQ-5						T only)
12

An OFF-delay timer, which is useful when the response of the connected device is slow, etc., an ON-delay timer, which is useful when the input specifications of the connected device require a signal of a fixed width, are possible with EQ-5 T.

The OFF-delay timer and the ON-delay timer can be used at the same time.

For DC-voltage type, set the DIP switch for the timer selecting to 'Timer ON' side.
