Safety Protection Measures For Users - Panasonic LP-S Series Maintenance Manual

Safety protection measures for users

This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of the Safety
of laser products by IEC 60825-1.
Perform the safety protection measure shown below before using the system.
For more detail instruction, refer to each of the standard.
Moreover, there is a case where related regulations are set for using the laser product depending on a country and a
region. When use this product, follow these regulations.
„ Construction of interlock system
For operating this product, construct the protective enclosure enclosing the range of the laser radiation for protecting
the exposure caused by the reflection of the laser radiation from the marking object or the surrounding objects, and
also construct the interlock system at the same time. Use the interlock connector equipped on the controller of this
product. Additionally, install the control part that is not to exposure to the laser beam. Refer to "Construction of interlock
system" (P.25) for details.
WARNING
„ Wearing protective goggles
For protection eyes of an operator, make it mandatory to wear goggles against laser beam in the laser control area.
For this product, use the laser protective goggles or glasses which meet the following requirements.
• The goggles or glasses that have Optical Density (OD) of more than 6 at wavelength 1060 nm to 1070 nm (1.06 to 1.07
micrometers).
• Through the goggles or glasses, the laser radiation indicator should be recognized.
The protective goggles can momentarily protect the eyes against the scattered beam. Never look at the direct beam or
reflected beam even when you are wearing the protective goggles.
„ Protective enclosure
In order to prevent exposure to laser beam accidentally reflected from the marking object or from its circumferential
areas, place a protective enclosure so that it can enclose the area in the range of laser radiation.
Construct the enclosure with proper reflectance, durability and thermal resistance materials that does not transmit a
wavelength of 1060 nm to 1070 nm (1.06 to 1.07 micrometers).
Recommended materials for the enclosure: metals such as iron, aluminum, or stainless steel.
Design the enclosure not to leak the laser beam from the joint parts.
Example of the joint parts:

„ Key control
In order to avoid the operation of the system by the person without authorization and allowance, the laser safety
manager must remove key and keep it when not in use.
WARNING
18
• Construct a system for re-pumping the laser manually as safety protection
measures after stop of the laser radiation.

Danger of laser exposures
• It is obligated by IEC/FDA/JIS that laser products shall incorporate a key-
actuated master control. Actuation of this product is basically controlled by
the key switch located on the front of the controller. 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 switch is already in ON position, and power is
supplied. In this case, be sure that the external system controls the operation
of the laser marker with a key-actuated master control.
