HORIZONTAL POSITION OF THE LIGHT CURTAIN
When the object's direction of approach is parallel to
the floor of the protected area, the light curtain must
be installed so that the distance between the outer
limit of the dangerous area and the most external
optical beam is greater than or equal to the minimum
safety distance S calculated as follows:
S = 1600(t
where H is the height of the protected surface from
the base of the machine;
In this case, H must always be less than 1 meter.
