3.10.2 Access protection
An example of reference monitor function used for access protection is shown in figure 3-23(a), (b).
Reference segments should be configured on each surface for displacement detection. Reference segments
should be configured such that displacement can be easily detected. The OSSD will switch to OFF-state
when access penetration is detected, and also if the distance between SE2L and the reference structure
changes. This function is compulsory for vertical applications.
