NOTE
T
he configurable object resolution has an influence on the protective field range availa‐
ble. 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 104.
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 new response time of the safety laser scanner 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 responds. 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.

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

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

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

Multiple sampling after monitoring case switching
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 monitoring case switching multiplied by the configured scan cycle time
including the supplement due to interference protection).
