Alignment
NOTICE
Recommendation
If there is no ball joint available already, we therefore recommend using a LAMTEC adjustable
holder with the FV40-10 ball joint. The viewing direction of the flame detector must cut the
flame (
see figure 6-1
).
Particularly when there is an additional sight tube in the burner or the view of the flame is
considerably restricted, it is very important to align the flame scanner to optimum effect.
The longer the sight tube, the more advantageous it is that it has a larger cross-section.
NOTICE
Alignment parallel to the axis
In the axially parallel arrangement, it can be difficult to detect that the flame has gone out.
Avoid aligning the F300K in an axially parallel arrangement with the flame.
The correct positioning (alignment) of the F300K is a decisive prerequisite for high availability
or for the achievable selection quality. In any case, you should always take into account that
the aperture in the UV and UVIR (double sensor) versions is very restricted due to the lens.
Align the compact flame scanner as follows:
•
Align the F300K preferably in such a way that it picks up the first third of the flame to be
monitored (high flame frequencies).
•
Also align the F300K in such a way that it picks up only a small part or, even better, none
of the radiation from other burners or the re-radiation from the combustion chamber (low
flame frequencies).
