2 The transmitter andreceiver are mounted on the ramof the press allowing the operatorto stay close to the workpiece asthe tools close at high to the location and size ofthe beam, multiple bends in thematerial are easily accomplishedwithout interrupting the laserbeam. Muting of the laser beam isrequired so that the thickness ofthe material will not shut downthe machine. The muting point isautomatically determined duringthe initial test stroke of themachine. First, the materialsurface is detected by the laser,then the operator confirms theposition by merely pressing a Learn button.

3 There are noswitches, photoelectrics orproximity switches to adjust. Themute point position is perma-nently monitored. A shift in theposition will be detected and themachine brought to a continuously moni-tors the speed and stoppingdistance of the moving member ofthe machine. If the crawl speed of10 mm/sec. is exceeded and/orthe stopping distance of mmis exceeded, LazerSafe will issuea stop command to the is no need for a separatestopping performance monitor. Comprehensive operatorprotection at close proximity toworkpiece Allows tools to close at highspeed, increasing productivity Complex shapes achieved with Tray/Box and Field Muted modes of operation Encoder feedback providesclosed-loop monitoring of speedand stopping distance of the ram Flat band of continuous laserlight detects obstructions assmall as 4 mm while still beingvibration tolerant Mute point automaticallydetermined.
