Light grid

Function displays

Behind the optics cover on the connection side of the profiles there is a green Power ON operating indicator LED and a yellow

status display LED.

Resolution and beam clearance

The mechanical beam clearance determines the smallest detectable object size. Crossing the light beams increases the

resolution of the light grid.

The devices are delivered without programmed height checking. The beam is crossed three times.

Resolution of the crossed beam arrangement

If three-way crossing of the beams is programmed, the resolution increases. For a three-way crossing,

this means that the increased resolution is offered after 25 % of the transmitter range or receiver range.

It must therefore be ensured that all objects pass transmitters or receivers with this clearance.
