Undercutting: The undercut must always be at least as low as the dead zone.With regard to the mounting height the observations presentedunder “Location Planning” apply.To prevent entry into the undercut, it is necessary to limit itsheight.

H Undercutting Retraction of the industrial laser scanner: Retraction of the laser professional scanner into the machine contourpresents an alternative to the undercut.However, retracting the FLSC too far will mean that the scanneris unable to monitor the full 180°. In such cases you need to de-sign the shadow sides to he inaccessible (point-of-operation guard).If you need to monitor the full 180°, for geometric reasons theretraction depth of the scanner must be limited to a maximum of 69.5 mm (corresponding to a protrusion of the FLSC beyondthe front of the machine of at least 86.5 mm).The observations regarding the detection reliability of the FLSCand the stipulations of EN 999 result in the following correlationbetween the minimum height of the scanning plane on thescanner HS

A !The necessary dimensions of the scanning plane in relation tothe fixed holes for the scanner are shown in the dimensionaldrawings in the section headed “Mounting the FLSC”.The minimum mounting height is based on the retraction depth.The deeper you can retract the FLSC, the lower you can mountit. Take into consideration the possible shadowing of the marginal areas when retracting the scanner. With regard to the resolution of the FLSC and the danger of crawling underneaththe scanning plane, the points made under “Location planning”apply.
