POSITIONING THE SENDER AND RECEIVER UNITS
Safety light curtains and access control barriers can be installed verti-
cally to be used as a shield in front of, or around a hazardous zone. In
cases where a larger surface around the hazardous machine needs
to be safeguarded, a horizontally mounted AOPD may be appropriate.
Generally speaking, it must not be possible to pass over, around, below
or go behind the protective field of the AOPD. If this cannot be guaran-
teed, then additional protective devices must be used.
If both vertical and horizontal accesses need to be secured, then two
protective screens forming an “L” shape, one vertical and one horizon-
tal, are necessary.
For practical details on L-shaped installations, please consult the rel-
evant paragraph on page 35.
