Mounting
The UV 41 (HE) must be mounted as
closely as possible to the ame to be
monitored.
For mounting the UV41 on the burner
a suitable EM1/x adaptor is required.
When mounting it, make sure that the
rubber sealing ring enclosed with the
UV 41 (HE) is inserted between the UV
41 (HE) and the mounting adapter.
The UV 41 (HE) sensor will also detect
external light as a ame, which is why
the UV 41 (HE) must be mounted such
that, for example, no daylight, ignition
sparks or UV sources can be detected.
The UV 41 (HE) tube is sensitive to
impacts, vibrations, etc., which is why it
must be mounted without vibrating it.
After the mounting work is complete,
all screws must be checked for tight t.
If temperatures of more than 60 °C are
reached at the UV 41 (HE), an adapter
tted with a quartz cover glass and,
if necessary, an additional purging
air connection must be used (upon
request).
Attention
The maximum allowed line lengths
must not be exceeded. Supply and
signal lines must be laid separately, as
far as possible.
Attention
The ame detector UV 41 (HE) is deliv-
ered without cable screw connection.
To guarantee the required traction relief
and IP protection class IP 54, a cable
screw connection M16x1.5 for cable
diameters 5 - 9 mm is required (3 x
0.75 mm², which corresponds to an
AWG of 20, to 3 x 1.5 mm², which cor-
responds to an AWG of 16).
The protective earth conductor must
be connected using an insulated
female connector according to DIN
46245.
