UVS 10
UV sensor for flame control of gas burners, only in
conjunction with Elster Kromschröder automatic
burner control units IFS, IFD, PFS and PFD, flame
detectors IFW or PFF or burner control units BCU
or PFU.
This function is only guaranteed when used within
the specified limits – see also “Technical data”. Any
other use is considered as non-compliant.

Installation
CAUTION
Please observe the following to ensure that the
UVS is not damaged during installation:
– Use UV sensor only in conjunction with Elster
Kromschröder automatic burner control units,
flame detectors or burner control units.
– Cool UV sensor with filtered air when subject
to higher temperatures (see “Accessories”). In
addition, this protects the sensor from dirt and
condensation.

▷
▷
Max. distance between UVS and flame < 400 mm
(16”).
▷
▷
It can be fitted using a ½” viewing tube that should
be aligned on the first flame third, as this is where
the highest UV radiation is generally found. The
inside of the steel tube should not be coated
and the tube should be directed at the flame
from above so that no dirt collects in front of
the UV sensor.
▷
▷
The UVS..L with quartz glass lens must be pre-
cisely aligned with the flame.
▷
▷
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. neighbouring
flames (this must be observed when monitor-
ing pilot and main burners in particular), ignition
sparks, arcs from welding devices or lamps emit-
ting ultraviolet light.
▷
▷
Do not expose the UV sensor viewing opening
to direct sunlight.
▷
▷
Supply cooling air to cool and protect the optical
system from soiling and condensation.
▷
▷
Max. cable length in accordance with the speci-
fications for automatic burner control units IFS,
PFS, PFD, flame detectors IFW, PFF or burner
control units BCU, PFU.
