Instruction Manual

Safety Information for LV Series

• This product is just intended to detect the object(s). Do not use this product for the purpose to protect a human body or a part of human body.

• This product is not intended for use as explosion-proof product. Do not use this product in a hazardous location a nd/ or potentially explosive atmosphere.

• LV-H35F/H62F uses glass parts. Since there is the possibility of breakage in the case of dropping etc, take adequate care when handling. When pressure is placed on the glass po rtion (the main unit detection part, the reflective surface of the reflector), the waterproofing of the product may be damaged so please take great care.

Safety precautions on laser product

• Use of controls or adjustments or the performance of procedures other than those specified herein may result in hazardous radiation exposure.

• The LV series product uses a laser diode as a light source.

Specifications of the laser diode change depending on t he model. Refer to the tables below.

Laser emission stop input (LV-21A/21AP/51M/51MP/11A)

Laser emission can be stopped by short-circuiting between the purple and blue (GND) wires when LV-21A, LV-51M or LV-11A used. When LV-21AP or 51MP is used, short-circuit between the purple and brown (12 to 24 V DC) wires to stop laser emission.

CAUTION

 Safety consideration

• Follow the instructions mentioned in this manual. Otherwise , injury to the human body (eyes and skin) may result.

• Do not disassemble this product. Lase r emission from this product is not automatically stopped when it is disassembled.

Precautions on Class I/1 Laser Products

• Do not stare into the direct or specularly reflected beam.

Precautions on Class II/2 Laser Products

• Do not stare into the direct or specularly reflected beam.

• Be careful of the path of the laser beam. If there is a possibility that the operator may be exposed to the specular or diffuse reflections, block the beam by installing a protective enclosure.

• Install this produ so that the path of the laser beam is not as

the same height as that of human eye.

The current value of received light intensity is displayed relative to the setting value, within the range -15% to +15%.

Detection is generally stable when t he received light intensity is at least ±10% different to the setting value, which is represented by the center bar of the LED monitor.

The illustration shows an example of a received light intensity of +5%.

Light is steadily received

Setting value

Light is steadily interrupted

The indicator turns on according to the difference between the received light intensity and the setting value. The current level of detection stability can be determined from this difference.

If detection becomes unstable (light cannot be "ste adily received" or "steadily interrupted") due to a change in the surroundings or the target, or for any other reason, readjust the sensitivi ty.
