Device design
The system slide-in module of the flame amplifier is based
on a signal processor circuit with fail-safe self-monitoring
system and has been approved for continous operation in
keeping with European standard EN298 as well as TRD
411 - 414. Every failure of component part will cause the
safe switching-OFF of the flame relay.
The flame scanner signal (see separate operating instruc-
tions of the flame scanner) reaches the sensitivity control-
lers in the form of a pulse telegram through a filter and
pulse shaper stage. Subsequently the flame signal is dis-
tributed to two different function channels.
