9.2 Flame Monitoring
9.2.1 Integral flame monitoring (option)
Purpose
The integral flame monitoring system is primarily used for standard applications (e.g. oil or gas
flames at a burner in a combustion chamber) because of it’s limited adjustment possibilities.
NOTICE!
We recommend the LAMTEC flame monitoring systems (like F 200 K 2 or f 250 with FFS 05
or FFS 06), if you have other requirements for the flame monitoring (e.g. combustion of coal
dust). You will find information on this devices in the corresponding manuals (DLT7600, and
DLT7502 / DLT 7503).
The task of the flame monitoring device is to scan the burner’s flame in combustion plants un-
affected from any condition in the combustion chamber (e.g. glowing nogging) and to release
the closing of the fuel valves at a flame blow out with an internal control command of the burn-
er control system.
The flame monitoring device has the following tasks:
–
Scanning the burner flame unaffected of the conditions in the combustion chamber (e.g.
glowing nogging)
– internal release of the control command to close the fuel valves at a flame blow out with
the burner control system
You may connect the following LAMTEC flame sensors:
FFS 06, FFS 05 UV, FFS 06, FFS 06 UV (with the following sub-types FFS 05, FFS 05 UV in
version for Ex zone 1 or Ex zone 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 (FFS 05 UV-1/ FFS 06 UV-1)
– Spectral radiation region = 210......380 nm (FFS 05 UV-2 FFS 06 UV-2)
– Spectral radiation region = 850....1200 nm (FFS 05-1)
– Spectral radiation region = 1200....2800 nm (FFS 05, FFS06, FFS 05-T, FFS 06-T)
– Pulse frequency ca. 10...200 Hz
– Pulse amplitude

10mV
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.
