Function
The integral method in the respective spectral range is used for the flame radiation analysis of the
compact flame controller.
After pre amplification, the unwanted portion of constant light is withdrawn from the output signal. The
subsequent sensitivity adjustment permits signal suppression for the adaptation to the respective
burner condition.
The subsequently connected band pass filter achieves that modulation of the typical flame radiation of
the primary combustion zone is evaluated only, and outside light signals from neighbouring burners
can be differentiated from the individual burner.
The further functional groups integrate the signal processing for the dynamic monitoring channel,
which, by means of a dark-phase monitoring, continuously checks the failure-safety of the unit.
A component defect leads to an immediate switch-off of the flame-relay, which is available as a poten-
tial-free changeover contact.
The switching state „flame on" is displayed by a yellow LED on the rear side of the unit, just as the in-
tensity of flame, which is displayed by a flashing green LED.
A flame intensity output 0(4) - 20 mA can be used for external displays. The range can be selected by
jumper see drawing on page 3.
The safety switch-off time, which always depends on the fuels to be detected, is factory adjusted to 1
second. Longer switch-off times in acc. to local specifications available as option.
