4.3.6.4 Distance from walls
Overview
T
he availability may be impaired if the protective field stretches as far as a wall or a
different object. So, plan to have a space between the protective field and the object. A
distance of the TZ value is recommended to ensure availability. (TZ = tolerance range of
the safety laser scanner, see "Data sheet", page 165.)

Important information
DANGER

azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
If the distance between the protective field and the wall is so large that a person can
stand in it, this person might not be detected. If needed, take suitable measures to
prevent this such as:
b
Attaching deflector plates
b
Attaching fence
