Safety Protection Measures
This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifica-
tions of the Safety of laser products (JIS C 6802) / FDA standards 21 CFR 1040.10 and 1040.11/IEC60825-1.
Perform the safety protection measure shown below before using the system.
For more detail instruction, refer to each of the standard.
1. Interlock system
In order to prevent exposure to laser beam accidentally reflected from the substrate to be marked or from its
circumferential areas, place a protective enclosure so that it can enclose the area in the range of laser
radiation, and construct the interlock mechanism in the system.
Additionally, install the control part that is not to exposure to the laser beam. Refer to "Construction of
Interlock System"(P.16).
For laser pumping is shut-off by interlock system, construct a laser re-pumping system by manual
operation for safety.
CAUTION
2. Wearing protective goggles
For protection eyes of an operator, make it mandatory to wear goggles against laser beam.
Purchase the proper type of the protective goggles in consideration of the wave length (Refer to " Caution in
Handling Laser Beam" (P.6), working environment, etc.
3. Protective enclosure
In order to prevent exposure to laser beam accidentally reflected from the substrate to be marked or from its
circumferential areas, place a protective enclosure so that it can enclose the area in the range of laser
radiation.
i.e., please made from acrylic resins, glass, metals, etc.
It is, however, recommended that the thickness of an acrylic or glass plate is more than 3 mm and that the
plate has a color to prevent secondary radiation beam.
4. Key control
In order to avoid the operation of the system by the person without authorizatio and allowance, the laser
safety manager must remove key and keep it when not in use.
It is obligated by IEC/FDA/JIS that laser products shall incorporate a key-actuated master control.
Actuation of Our laser marker is basically controlled by the key switch located on the front of the
contloller box. However, in considering situations when the laser marker is operating as a part of a
larger system, the laser marker turns on if the key swith is already in ON position, and power is
supplied.
CAUTION
In this case, be sure that the external system controls the operation of the laser marker with a
key-actuated master control.
5. Power failure recovery
When power failure occurs on the laser marker, construct a laser re-pumping system by manual operation for
safety.
6. Radiation direction of laser beam
To assure safety, be sure to place the protective enclosure. Measures should be taken so that the direction of
laser radiation can be seen and checked by others as well as an operator. (Labels of cautions, instructions,
and open indication are adhered to the system at delivery from the plant. Do not peel them off.)
