– Signal processing with two separately constructed and alternately activated transmission
channels.
– Continuous comparison of the output levels for anticoincidence.
The transmission range of the digital frequency analysis covers signal transmittance between
10Hz or 25Hz (factory configuration) and 200 Hz.
Mains frequency signals and their harmonics are filtered, with a filter bandwidth of 3 Hz.
Setting of the sensitivity of the flame scanner FFS08 IR, FFS07 IR/UV.
Adjust sensitivity with switch S1 and S2. You will find the switches after opening the scanner’s
housing.
WARNING!
Do not open FFS08 UV and FFS 06 UV!
Setting of the sensitivity is not possible for FFS08 UV and FFS06 UV.
