CHAPTER 3:
USE and MAINTENANCE
In order to use the device on a daily basis, the Installer must take care of installing all the
Safety devices consists of casings or protection barriers suitable for preventing access to the
laser device and/or the work area and preventing leakage of dangerous laser radiation. The
use of suitable protection devices is able to reduce the acceptable emission limit (AEL) of the
dangerous Class IV laser source, to the level of a Class I source, considered not dangerous.
The casings or protection barriers must be sufficient for intercepting the emitted laser radiation
from the source and resistant to perforation.
For the Megalight™ engraving system and for medium-low power laser, a metallic protection of
a 1 mm thickness is able to completely and indefinitely shield non-focalized laser radiation.
If it is necessary to access the device inside the casing by removing part of the casing, it is
necessary to use safety blocks, which reduce the laser radiation to non-dangerous levels when
they are activated. This can be created by electric interlocks, which must be in conformance
and tested as a safety device.
Any inspection or observation windows must have built-in Optical Density filters able to lower
the AEL to Class I. The filters must be in conformance and tested as a safety device.
General use instructions for Class IV lasers
The use of remote controls is also envisaged for Class IV lasers as well as starting with a key
command, existence of an emission warning, availability of an attenuation/shutter command,
positioning of controls outside the radiation access area and clearly visible appropriate warning
labels.
The manufacturer of Megalight™, makes the possibility of complying with these regulations
available to the Installer. Nevertheless, it is the Installer’s responsibility to integrate all the
necessary safety devices in the laser system.
The external safety devices include:
•
Connecting an interlocking contact to the remote locking connector (External
Interlock) which blocks laser emission and prevents it from restarting if it is open.
•
Connecting an emergency laser contact to the connector (Command Box) which blocks
laser emission and only allows restarting after an intentional manoeuvre if it is open.
•
Equipping the system with a key start command connected to the connector
(Command Box) which can be removed in the OFF position to prevent unauthorized
personnel from using the laser system.
•
Connecting an external device for enabling/disabling the shutter to the connector
(Command Box), aimed at temporarily blocking laser emission.
•
If the three color led on the rear panel of the rack is not directly visible, connect an
external device which signals laser radiation emission in progress, for example a
flashing red light, to the connector (Command Box).
•
Position the Operator commands in an ergonomic position outside of the optical risk
area.
•
Repeat the warning labels on all removable panels, which when removed, allow access
to the optical risk area.
