If the muting function is configured, the muting is
terminated when muting period exceeds the specified
maximum muting period

displacement of the reference boundary structures or UAM
should cause the OSSD to switch to OFF-state when
displacement exceeds the allowable tolerance. This is
applicable especially if the angle of approach exceeds ±30º
from the detection plane
21 Safety relay life span is still valid
