LFL1 333 SIEMENS CONTROL BURNER☎️✔081388666204🔥PT Indira Mitra Boiler

Burner Controls LFL1...
Burner controls
 For gas, oil or dual-fuel forced draft burners of medium to high capacity
 For multistage or modulating burners in intermittent operation
 With checked air damper control
 Flame supervision
– with UV detectors QRA2 / QRA4 / QRA10
– and ionization probe
The LFL1 and this Data Sheet are intended for use by OEMs which integrate the
burner controls in their products!
Use
 Control and supervision of forced draft burners of direct spark flame or interrupted
pilot construction
 For medium to high capacity
 For intermittent operation (at least one controlled shutdown every 24 hours)
 For universal use with multistage or modulating burners
 For use with stationary air heaters (WLE)
 For use with dual-fuel burners
 Type-tested and approved in accordance with DIN EN 298
The flame supervision is ensured via a flame detector QRA2 / QRA4 / QRA10 or
ionization probe. The difference between 01 series and 02 series is the duration of the
safety time for the pilot burner of burners equipped with pilot gas valves. For
atmospheric burners of high capacity, use the LFL1.63

It is important to achieve practically disturbance- and loss-free signal transmission:
 Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
 Observe the maximum permissible detector cable lengths (refer to «Technical data»)
 2 UV detectors QRA2 / QRA4 / QRA10 can be connected in parallel (observe the
warning note)
 In connection with the QRA2 / QRA4 / QRA10, earthing of terminal 22 is mandatory
 The ionization probe is not protected against electric shock hazard
 Locate the ignition electrode and the ionization probe so that the ignition spark
cannot arc over to the ionization probe (risk of electrical overloads) and that the
ignition sparks cannot adversely affect the supervision of ionization
 Supervision with both ionization probe and UV detector QRA2 / QRA4 / QRA10 is
possible, but for safety reasons – with the exception of the second safety time «t9»
– only 1 flame detector may be active at a time. At the end of the second safety
time, 1 of the detectors must be inactive, however, that is, the detected flame must
have extinguished, e.g. by switching off the ignition valve via terminal 17
