4.3.1 Protection from influences
A safety laser scanner can be influenced by the beams from a different laser source
in c
lose proximity to it, e.g. by another laser scanner. This may impair the machine’s
availability. 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 have a negative impact on the availability of the machine. That is to
say, the safety laser scanner switches off the machine even though there are no people
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 102.
•
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 100.
•
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 198.
•
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.
NOTE
Y
ou must comply with the standard ISO 13855 when choosing the mounting method.
