wire edge is connected. hen the photo system is properly installed and aligned, the infrared beam will detect any
obstruction in the path of the beam. pon detecting an obstruction, closing door will stop and reverse to full open.
The Nice operator control circuit continuously monitors the correct operation of the photo system. If the photo
beams are not connected or not functioning properly, the operator will go into fail-safe mode and closing door will
reverse to full open. In fail-safe mode door can only be closed by constant pressure on close.
