Multibeam Models; Horizontal Positioning Of The Light Curtain - Reer EOS2 A Manual

Multibeam Models

These models are suitable for whole body
detection and must not be used to detect arms
or legs.
The minimum safety
according to the following formula:
The recommend height H from the reference surface G
(ground) is as follows (ISO 13855 Standard) :
EOS2 2B
EOS2 3B
EOS2 4B

Horizontal positioning of the light curtain

When the direction of approach of the body is parallel to
the plane of the protected area, the light curtain must be
positioned so that the distance between the far end of the
dangerous area and the outermost beam is equal to or
greater than the minimum safety distance S calculated as
follows:
S = 1600(t
where H is the height of the protected surface from
the machine reference plane;
In this case, H must always be less than of 1m
(ISO 13855 Standard).

distance S is
S = 1600 (t + t ) + 850
