conrm that the abnormal condition is removed, and

then contact us or our sales representative. Never

repair the device by yourself since it is dangerous.

• Do not use the device by a power voltage outside

12-24 V DC. It may cause a re or an electric shock.

• Avoid wiring a cable and high-voltage or power cable

in parallel or wiring them in a same piping. It may

cause a malfunction of the device.

the device is subject to direct sunshine)

• Dusty place

• Place with insufcient ventilation

• Place where static electricity is likely to be

generated

• Place involving corrosive or ammable gases

• Place where the device is subject to water, oil,

and /or chemical splashes

• Place with direct vibration and impact

• Do not handle electric cables as follows. Otherwise,

cables may be damaged, resulting in a re or an

electric shock.

• Damage • Torture • Pull

• Twist • Bundle, • Put heavy stuff

• Do not touch the device or its cable with wet hand.

Otherwise, it may cause an electric shock.

• Do not insert any improper cable or metal into

electrical terminals. It may result in short-circuiting

inside the device, causing a re, an electric shock,

and / or a failure.

• Do not drop this device nor give any strong impact

on it. It may result in personal injury, if it falls on your

foot, or a device failure.

• Securely mount this device. This device may

fall off due to insufcient mounting or unstable

mounting position, resulting in personal injury or

an accident.

• Wipe off the dirt on this device with a soft, dry

cloth or a rmly squeezed cloth wet with diluted

neutral detergent.

• Please note that there may be dead pixels or

bright pixels with the LCD screen although it

has been produced with a super-high precision

technology.

BASIC INFORMATION BEFORE USE

Conrm that the device is not damaged before using it.

Names and Functions of Components

Operating Buttons

Use to register patterns or colors, set

each item, or switch the display mode

of the screen.

See "Names and Functions of

Operating Buttons" on Page 15.

LCD Display

Displays the images and the detection

result taken by the built-in camera.

Also, displays each set item and set value.

See "Display on LCD Screen"

on Page 12

Power / Signal Cable Connector

Connects the power / signal cable.

See "Wiring of Power Cable" on Page 10.

Cable Connector

Connects external cable (Option).

See "Options" on Page 11.

Mounting Hole

Using a screw M4×50 mm or more is

recommended.

See "Outside Dimensions

Drawing" on Page 66.

Built-in camera and

lights are equipped

on the back.

Precautions When Mounting This Sensor

• Mount the sensor leaned by 5°-45° so that

lighting should not be reected by a work.

5°-45°

Work

• Detection may become successful by changing

the setting even if a detected image is

displayed as shown in the right gure.

See "Changing Set Value" on Page 48.

Tilt the sensor by 10°-40° to avoid the mirror reection when a

work is shiny.

• Take caution so that the external lighting (light

from uorescent light, etc.) is not reected.

Ramco Innovations

phone 800-280-6933

• The work imaging condition changes depending on the distance

between the sensor and a work and the tilted angle of the sensor.

When detecting a slight difference in shape, smear, or aw of a work,

furnish more stable bracket for this sensor and design the machine so

that attering of works is reduced as much as possible.

• Refer to the standard object distance of each model as to the distance

between this sensor and a work.

See "Specications" on Page 65.

If the object distance is too near, the sensor becomes out of focus,

causing a irregular lighting, while it is too far, the sensor is likely to

receive the inuence of the turbulence light since the light does not

reach the work.

See "Correction of Brightness Irregularity" on Page 46.

• When a work moving very fast is going to be detected, the shutter time

(brightness) has to be shortened. In such a case, make the distance

between the sensor and a work closer or add additional external

lighting since quantity of light becomes insufcient with only the light

built in this sensor.

See "Options" in Page 11.

• The shutters of the image sensor of this device open in sequence from

the right to the left in the screen. Because of this reason, the work

traveling from the right to the left is displayed wider and the one

traveling opposite is displayed narrower.

In order to detect a slight difference in shape, slow down the travel

speed of a work.

• Please note that there may be dead pixels (pixels that cannot receive

light correctly) with this image sensor. Although dead pixels may

not detect or detect incorrectly, they will not be any problem on the

practical use since they are very few.
