NOTE
The 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,

Multiple sampling
DANGER
Hazard 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
laser 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‐
ardous area protection or vertical hazardous
point protection under clean ambient condi‐
tions
2×
Stationary application: such as vertical access
protection
Only 2-time multiple sampling may be used for
vertical access protection.

Mobile application
4×
Stationary application: such as horizontal haz‐
ardous area protection under dusty ambient
conditions

Multiple sampling after object detection
The set multiple sampling also applies by default if a field becomes free again after an
object detection. That means, when the field is free again, the free field is scanned the
same number of times until the safety outputs switch back to the ON state.
If you activate the
Activate different multiple sampling rate after object detection
option, you
can specify deviating values for the monitoring level or for individual fields. This may
cause the outputs to switch back to the ON state faster or slower after a field has
become free again.
