ing and contains the device type designation and the se-
rial number.
5.2 Functional description
The compact flame controller CFC 100 disposes of a small
banded UV sensitive detector unit which generates an im-
pulse diagram proportional to the UV radiation. The follow-
ing sensitivity setting allows a processing of the signal for
the adaptation to the heating relations. Other functional
groups contain among other things the signal processing
for the dynamic monitor canal which checks the fail-safety
of the device continuously.
A components defect leads to the immediate disconnection
of the flame relay which is available as a potential free
changeover contact for the burner control.
The switching state becomes additional shown by yellow
LED at the back of the device. The flame intensity of the
compact flame controller can be read directly in the device
by means of a pulsating green LED. To the visualisation or
remote indication a current output of 4-20 mA is available.
The max. load of 500

should not be exceeded.
The safety switch-off time for operation is put by factory
on one second. Optionally longer safety switch-off times
are possible if requested.
