When the installation of RAY-LG is not possible inside the side guide, it may also be mounted from the
back side (Figure 5.1). Holes of min Ø 10 mm must be drilled into the profile to allow the light to pass
through.
If two light curtains are installed parallel to, but not in line with the door panel in front of and behind the
guide rail, the descending door will not interrupt the active beams. (Figure 5.2) However, blanking may still
be required if any obstructing part of the door (e.g. strengthening bars, hinges, junction boxes) interrupt the
light curtain. A beam blocker can be employed to shade the diodes on one side, but it must be mounted so
that at least one element is continuously covered during door closure (Figure 5.2).
3 seconds after the last beam was interrupted by the now closed door, the output signal is interrupted.
