Description

Many safety curtains can be highly effective if used properly. They allow multiple operators access to the press and prevent unauthorized personnel from injuring themselves. They also make it possible to use a foot switch instead of a two hand push button station.

Floating Beams

Many press brake light safety curtain systems have a floating beam option, individual or multiple infrared beams may be broken by the part being formed. Some safety curtains allow up to eight inches of beams to be floated. Floating beams can be extremely dangerous if used improperly. Just consider a press with a three inch stroke and the light curtains safety allows you to float up to eight inches of beams. We do NOT recommend floating beams!

Channel Select or Canceling

Beam canceling is an option on some light curtains. Canceling beams allows you to blank out or ignore a given number of the beams. It is a very useful option if used properly and safely. For instance, if you have support arms mounted to the front of the press, canceling the beams that are obstructed by the support arms allows you to operate the press while still protecting the die opening. Misuse of this option is extremely dangerous and should be supervisor controlled. Blanking beans to allow the part being formed to be ignored by the light curtain should never be used. The gap in the light curtain array of beams would allow the operator to inadvertently penetrate the danger zone.

Programmable Channel Select

Some safety curtains can be programmed to selectively cancel a given number of beams during the forming operation. For instance, a box shape is being formed. On the first stroke the safety curtains are programmed to ignore only one beam. A four inch high ninety degree bend is made. The part is rotated ninety degrees. Now the side of the part is obstructing four inches of the light curtain. For the remaining strokes the light curtains safety must be programmed to ignore four inches of the light curtain. Four inches of canceled beams is extremely dangerous.
