Alignment Indicators
Two Yellow Alignment indicators (Top and Bottom) tell the alignment status of the top and bottom beams in the light screen. This is
helpful for sensor alignment: first align the Top beam (the sync beam), then the bottom beam. The Alignment indicators also flash
together to indicate a manual reset is needed (Latch output models).
Indicator Color
Top Alignment Yellow

Status Indicators
