Interlock Switches
Interlock switches must be fitted to all access guards preventing access to
the laser output lens and marking area that can be opened without the use
of access tools.
Interlock switches must be wired into the laser control circuit so that the
laser beam is disabled when the guard is removed.
Emergency Off
Integrate the laser into the emergency off circuit of the machine into which
the laser is integrated. Install an emergency off push button near the laser
marking systems which turns off the laser. Connect the emergency off push
button via the interlock circuit to the controller.
Guarding Labels
Domino recommend that the following information is prominently displayed
on the guard:
WARNING: Class 4 laser is enclosed in a Class 1 enclosure.
Operation of the system with safety guards
removed may result in hazardous exposure to
laser radiation.
These labels are supplied with the laser system. Additional labels are
available from Domino Printing Sciences plc as part of the Guarding Labels
Kit, Part Number L007628.
