6 Information for Mounting and Installation
The compact flame detector :
– is to be aligned in such a way as to cover the first third of the flame for single monitoring.
– has to cover the flame root area for a simple selection during the ’Flame in’ control state
(area of high flame frequencies), and during the ’Flame out’ state to only detect the resid-
ual radiation caused by the ’offshoots’ of the other flames in the combustion chamber (ar-
ea of low flame frequencies) or by reflection.
– If possible avoid aligning the compact flame detector parallel with the flame axis , since
in this position, a loss of flame can hardly be detected.
In order to reach a high availability and a high selection quality, it is very important to place the
compact flame detector at the appropriate location.
Make sure in every case that the aperture angle for the UV solutions is only about 8°. For this
reason we recommend to use the FH40, FV40, FS 51and/or FS 56 adjustable holding device
(ball-and-socket joint), unless already in place.
Correct alignment is of paramount impor-
tance in particular in such cases where there is an additional viewing tube inside the burner
or where the visibility of the flame is considerably restricted. With increasing length of the
sighting tube is a correspondingly larger cross-section advantageous.
NOTICE
The installation should take place with the holding device provided by LAMTEC .
Otherwise pay attention to an isolated mounting to avoide any interference from compensat-
ing currents provoke over the cable shield.
The installation site must be easily accessible to allow a perfect observation of the visual op-
erational controls even during operation of the furnace. When replacing the compact flame de-
tector, make sure to install a device having the same identification marking.
Make sure that the maximum admissible ambient temperature is not exceeded at the in-
stallation site. This applies in particular to radiant heat.
