Overview
Flame monitor
IR Flame Detector FFS 06
For IR flame detectors and UV flame
detectors, the minimum response thres-
holds are 15 mV AC and 25 mV AC,
respectively. Refer to the technical
documentations of the flame monitors
for further commissioning instructions.
Note: The UV flame detectors are not
provided with this sensitivity adjust-
ment. They are optimized by aligning to
the flame to be monitored in the best
possible way using the measurable
signal voltage on the measuring line.

Assembling and commissioning of
flame detectors
The flame detector should be installed
in the provided mounting at an inspec-
tion opening of the burner in a way that
the burner flame to be monitored is
clearly visible in the overall operational
range of the furnace. The sensitivity of
the IR flame detector FFS 06 to the bur-
ner flame can be adapted via the thres-
hold switch in the flame detector. In
doing so, the sensor housing should be
unscrewed and the setting on the thres-
hold switches made according to the
Figure (2).
