Function
Supervision of light radiation of oil flames in the visible range of the light spectrum.
The light-sensitive element is a photo resistor whose electrical dark resistance lies in
the M range.
As the intensity of light increases, the electrical resistance drops to the k range and is
evaluated by the burner control for generating the flame signal.
In contrast to the photocell ot the RAR, glowing firebrick in the combustion chamber
can be detected.
