5.1 Application
In combination with a BFI flame scanner, the flame ampli-
fier 3016 offers a fail-safe flame monitoring system. The
fast switch-off time (adjustable between 200 and 650 ms)
can be considered as the most excellent feature. More-
over, a malfunctioning channel has also been integrated,
indicating flame scanner; flame amplifier or wiring errors.
5.2 Front plate
The display of the current flame intensity is achieved via a
10 section bar graph display. The sensitivity level I or II is
displayed via two LED’s (green) A further LED (yellow)
signals flame-on. Finally the error-LED (red) is situated on
the front plate.
5.3 Function
The BFI flame monitoring system consists of one flame
scanner (for instance type 2) which transmits, depending
on the flame intensity information received, more or less
pulses to the flame amplifier via the connection cable. The
amplifier evaluates the pulse message and produces, de-
pending on intensity, the flame-on or off signal. In addition
to this the intensity evaluation is interrupted for 200ms per
sec. for a self-test. In case of malfunction detection, the
system switches off.

the functional groups in the flame amplifier 3016.
