As foreseen by the correct muting sequence, occupation and subsequent
freeing of sensor 3 determines the end of the muting cycle. Each time
sensor 3 is involved other than in the way envisaged, fail muting status is
generated. For this reason:

To avoid interference between the light barrier and the muting sensors,
the light barrier must be assembled so that the synchronism beam is on
the part opposite the muting beams.
In ARGOLUX AS safety barriers, the synchronism beam is generated by the
ASR receiver and is the first beam starting from the output connector part:
