light barrier system offers the possibility to combine the three
light barriers in different ways. Such a combination within this light barrier
system we call an "action" mode.
Certain states of the light barriers involved are assigned to each action mode.
As soon as these states become ‘true’, the action mode is considered to be
met. This status is then reported to the digital part as a trigger for an action.
Each action mode is represented by a pictogram. In these pictograms, the
numbers 1 to 3 indicate the light barriers involved.
A parameter set is saved for each action mode, which determines the optical
and timing behaviour of the light barriers.
The one beam barrier

, Level:
The one beam barrier consists of the beam of the light barrier 1. If this is
interrupted, the action mode is met.
After the action mode is met, the light barrier must first be reset (the obsta-
cle mist move from the beam) before a new action can be triggered.
