Chapter 17: Disqualification (Important Warning)
In order to prevent and show
disalignements caused by any
obstacle placed in the active
beam of the barriers at system
off, it is necessary to connect
the disqualifiation output
(terminal D) in series to the
exchange of the alarm relay or
alternatively, use it to control an
additional relay, whose
exchange has to be put in series
to the alarm line.
NOTE
The output D gives a
transistorized negative (max. 50
mA) which fails when the signal
level goes under a minimum
level for over 30 seconds.
