1.2.1. SAFETY SWITCHES
The Laser Marker includes the safety switch (interlock).
•
Lock control . Consist of a micro-switch located on the protective cover of the laser tube. When this
cover is removed while the system is working, the message "Laser Locked" will be displayed on the
Laser Marker screen and the laser is deactivated.
1.2.2. PROTECTIVE HOUSING
The area between the marking head and the printing surface must have a protective housing to prevent
user access to the Laser Marker.
Making this protective housing is the responsibility of the installer in each country.
The housing delivered by HITACHI may not be enough, and each client must adapt the housing to its
production line, because the final protection must be a closed protection, and the housing delivered by
HITACHI may not be completely closed.
This housing is a polycarbonate housing, which prevents the reflections of the laser beams to the user,
as indicated in the following pictures:
The protection is mounted around the lens, and fixed with screws on the top part of the protection.
The polycarbonate does not permit the laser beam to go through it and redirects all the reflections to the
production line.
All the technical requirements that the housing must accomplish found in EN 60825-4 norm (Europe) and
in IEC 60825-4 (International).
One of the principal requirements that the
housing must accomplish is the capacity to
catch all the laser beam reflection that laser
emits when it starts to work and marks.
As we observe in the picture, the reflections
of the laser beam are always inside the
protective housing.
