Warning: CRUSHING HAZARD OUTSIDE OF THE PROTECTION AREA
If the tool is large enough to present a crushing hazard outside of the protection
area provided by the laser guards it is necessary to provide additional safety
measures, such as increasing the slow speed distance of the machine (as
recommended by European Standard EN12622).
If the Sentinel Plus is in Special Tools mode, and a large tool has been
detected that requires a 20mm mute/slow speed point, a Stop at Mute will also
be performed on every stroke.
3.9.2
Thermal Compensation Mode
The LZS-005-
R transmits a two dimensional ‘block’ of laser light that surrounds the tool,
and projects a silhouette (or shadow) of the tool onto the receiver window. A camera in the
receiver captures and analyses an image of the silhouette to detect if an obstruction is
present.
