NOTE
T
he configurable object resolution has an influence on the protective field range avail‐
able. The finer the object resolution configured for the safety laser scanner, the shorter
the available protective field range.
The protective field range is shown to you, see "P
arameters for the safety laser scan‐
ner", page 90.
Multiple sampling
DANGER
H
azard due to lack of effectiveness of the protective device
Persons or parts of the body to be protected may not be recognized or not recognized in
time in case of non-observance.
A higher multiple sampling increases the response time.
b
Make a note of the safety laser scanner’s new response time in Safety Designer.
b
Adjust the minimum distance from the hazardous point to the new response time.
Multiple sampling indicates how often an object has to be scanned before the safety
la
ser 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.
b
Increase the multiple sampling up to 16.
✓
An object must be this many times.

Only 2-time multiple sampling may be used for
vertical access protection.

Multiple sampling after switching between monitoring cases
DANGER
H
azard due to lack of effectiveness of the protective device
If combined with very short switchover times, higher multiple sampling after switching
between monitoring cases can result in a person or part of their body not being
detected.
b
Make sure that every monitoring case is active for at least the amount of time
required for detection by the safety laser scanner (setting for multiple sampling
after switching between monitoring cases multiplied by the scan cycle time set,
including the supplement due to interference protection).
