10 Appendix
Approvals for flame scanner/sensor in conjunction with ETAMATIC OEM with validity from that
date are not valid for F250, FFS05 or FFS06.
Replacement for FFS05 = FFS07
Replacement for FFS06 = FFS08
Replacement for F250 = F152 or F200K (depending on application)
10.2.1.2 Characteristics flame sensor
Input variables - optical flame sensor
Required input values from the flame's emitted radiation indication "Flame present”
– Spectral radiation region = 260......400nm (FFS07 UV-1, FFS08 UV-1)
– Spectral radiation region = 215....360 nm (FFS07 UV-4, FFS08 UV-4, replace UV-2)
– Spectral radiation region = 1200....2800 nm (FFS08 IR-1, FFS07 IR-1, FFS07 IR-1 T,
FFS08 IR-1T, FFS08 IR-1 T/S2)
– Pulse frequency ca. 10...200 Hz
– Pulse amplitude 10mV
10.2.1.3 Self Monitoring
– 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.
