Warning!
Condensation, formation of ice and ingress of water are not permitted!
If not observed, the safety functions are no longer ensured and there will be a
risk of electric shock!
With this type of flame supervision, the radiation of oil flames in the visible band of the
light spectrum is used for generating the flame signal. The light-sensitive element is a
photocell. When illuminated, it generates DC voltage, causing a current to flow to the
input of the flame signal amplifier. Hence, the RAR... is an active detector. The photo-
cell is insensitive to infrared radiation so that glowing firebrick in the combustion cham-
ber cannot produce a flame signal.
