Multiple sampling
Mult
iple sampling indicates how often an object has to be scanned before the safety
laser scanner reacts. A higher multiple sampling reduces the possibility that insects,
weld sparks or other particles cause the machine to be shut down. You will increase the
machine’s availability.
A multiple sampling of 2 is the minimum setting.
A higher multiple sampling increases the response time and influences the minimum
distance.

Application Recommended multiple sampling
Stationary application: such as horizontal haz‐

dous area protection or vertical hazardous
point protection under clean ambient condi‐
tions

Stationary application: such as vertical access
protection
Only 2-time or 3-time multiple sampling may
be used for vertical access protection.

Multiple sampling after switching between monitoring cases
W
hen switching between monitoring cases, it is possible that a person may already be
in the newly activated protective field when switching takes place. In order to ensure
that the person is detected quickly and the dangerous state is brought to an end swiftly,
you can adjust the settings for multiple sampling immediately after switching between
monitoring cases – regardless of any other multiple sampling in place.
For persons and body parts to be reliably detected, each monitoring case must be
active for at least as long as the safety laser scanner requires for detection (set multi‐
ple sampling after switching between monitoring cases multiplied by the scan cycle
time).

sampling after switching between monitoring cases is one scan fewer than any
other multiple sampling in place. This reduces the possibility that insects, weld
sparks, or other particles cause the machine to be switched off. This increases
machine availability. The standard response time applies from the outset in the
new field.
