Near range
In close proximity (50 mm-wide area in front of the front screen), the detection capabil‐
ity of the safe multibeam scanner may be restricted.

Response time of the safe multibeam scanner
Overview
The response time of the safe multibeam scanner must be taken into account, among
other things, so that the safe multibeam scanner can be positioned in a suitable
location and the protective fields can be sized correctly.
The protective device’s response time is the maximum time between the occurrence of
the event leading to the sensor’s response and the provision of the switch-off signal to
the protective device’s interface (for example the OFF state of the safety output).
The response time of the safe multibeam scanner depends, among other things, on the
set multiple sampling.
Influence of signal transmission
In addition to the protective device’s response time, further signal transmission and
processing also influence the time up until the end of the dangerous state. This
includes a control’s processing time and the response times of downstream contactors,
for example.

Monitoring case switching
Overview
The safe multibeam scanner monitors all configured protective and warning fields in
parallel. After switching to another monitoring case, the safe multibeam scanner can
access the results for the now active protective and warning fields without delay. This
also applies if multiple sampling is configured.
The input signals for monitoring case switching are transmitted via CANopen.
