DANGER
H
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.
The optical beam path must not be disrupted, e.g. if the system is incorporated into
paneling.
b
Do not attach an additional front screen.
b
If a viewing slit is required, make sure that its size is sufficient, see "Dimensional
drawings", page 167.
NOTE
C
ertain optical and electromagnetic ambient conditions can affect the safety laser
scanner. This may impair the machine’s availability. That is to say, the safety laser scan‐
ner switches the machine off, although no people are located in the protective field.
Take note of the following for a high level of availability:
b
Avoid having strong electric fields in the vicinity of the safety laser scanner. These
may be caused by nearby welding or induction cables, for example.
b
Prevent condensation forming on the optics cover.
4.3.1 Protection from influences
A safety laser scanner can be influenced by the beams from a different laser source in
close proximity to it, e.g. by another laser scanner. This may impair the machine’s avail‐
ability. That is to say, the affected safety laser scanner switches the machine off,
although no people are situated in the protective field.
A safety laser scanner may be dazzled by a strong external light source in the scan
plane. This may impair the machine’s availability. That is to say, the safety laser scanner
switches the machine off, although no people are located in the protective field.
You can use the following measures to increase the availability:
•
The safety laser scanner has a function for interference protection. The scan cycle
time is adjusted in small increments. You can increase the availability by choosing
different modes for interference protection in adjacent safety laser scanners, see
"Additional interference protection", page 90.
•
Higher multiple sampling reduces the likelihood of a laser source influencing the
safety laser scanner. You can increase the availability by setting multiple sampling
to the highest value permitted in your application, while taking minimum distances
into account, see "Multiple sampling", page 89.
•
You can further increase the availability by choosing a suitable mounting method,
see "Mounting methods for protection from interference from systems in close
proximity", page 183.
•
Avoid external light sources in the scan plane. Mount the safety laser scanner so
that it cannot be dazzled by incoming sunlight. Do not position halogen lights,
infrared light sources or stroboscopes directly on the scan plane.
You can check the beam path of the safety laser scanner with the LS-80L scan finder
(part no. 6020756).
NOTE
Y
ou must comply with the standard ISO 13855 when choosing the mounting method.
