NOTE: The top of stroke position MUTE: The mute function mutes or assumes a down acting press bypasses the light curtain making it brake. This is the ram open insensitive to obstructions in the sensing position and would be the bottom position on an up acting field. With the press brake stopped at this point, insert the part into position. The light curtain can be muted at this point so the part if small can be held as necessary, and if the part is large the light curtain will not interfere with the process because it can be muted. By using the above procedure the hazardous portion of the cycle is protected by the active light curtain and the actual process of bending the material is not hampered by the light curtain because it can be muted from the point at which the die is ¼ inch or less open, through the bending portion back to the open position. Some light curtains require external muting devices to bypass the protection provided by the light curtain at the ¼ inch point while others have built in muting features. The ISB MERLIN 3000 series has the muting function built into the light curtain. WARNING: The muting of the light curtain must be adjusted for each set up so that muting does not occur before the ¼ inch point. The MERLIN 3000 light curtains also have additional features which assist in the processing of large parts on press brakes. In all cases the part should be held with both hands outside the plane of the light curtain during the hazardous portion of the cycle. 56 FLOATING BEAM FEATURE: The floating beam feature allows one or more beams to be blocked without the output of the light curtain opening. This feature is useful when holding a large flat part in the plane of the light curtain. The floating beam feature allows the part to move in and out of the beam without shutting down the press brake. PROGRAMMABLE BLANKING: Many large parts are processed completely without putting the part down or changing the set up. This is most often done when using automatic back gauges to reposition the material stops so multiple bends can be processed. When this is done it is quite common that a flange bent on a previous step will extend through the plane of the light curtain blocking one or more beams on a subsequent step. Again, if the part can be inserted at the ¼ inch position the programmable blanking feature is still not needed. If the flange is relatively small the floating beam feature may be enough to allow operation to continue.
