Safety precautions on laser product

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

„ Warning labels

Safety features

„ Laser ON alarm indicator

The laser ON alarm indicator will start flashing after power is turned on. The lamp
will remain ON for as long as the laser light is emitting. This alarm indicator can be
seen even when wearing protective goggles

.

„ 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.

„ Label location

Warning labels are attached to the sensor head, as shown below.

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 and/
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 portion
(the main unit detection part, the reflective surface of the
reflector), the waterproofing of the product may be damaged
so please take great care.

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.

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

Do not disassemble this product. Laser 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.
