Installation
CAUTION
Use UV sensor only in conjunction with Elster
Kromschröder automatic burner control units,
flame detectors or burner control units in order to
avoid damage.
▷
It is preferable to install the unit inclined from
above or in the horizontal.
< 400mm
(16”)
▷
Distance between UVS and flame: max. 400 mm
(16").
▷
The UV sensor may only be exposed to the UV
light of its own flame. It should be protected
from other sources of ultraviolet light, e.g. neigh-
bouring flames (this must be observed when
monitoring pilot and main burners in particular),
ignition sparks, arcs from welding devices or
lamps emitting ultraviolet light.
▷
Avoid exposing the UV sensor viewing openings
to direct sunlight.
▷
Protect the viewing openings against dirt and
moisture.
