Product Description
The analog light transmitter
G43111120 makes it possi-
ble to convert analog light
values to be transmitted on
the Dupline
bus.
The light value can be trans-
mitted in parallel on 8 chan-
nels, which are independent-
ly programmable, and can
thereby be compared to 8
different threshold values in
the Channel Generator
G38900014 version 2.02 and
activate field units accordingly.
The design of the LUX
makes it possible to mount
the sensor discreetly, e.g. on
walls.
No external power supply is
required, since the sensor is
supplied from the Dupline
signal wires.

channel allocation
The LUX sensor transmits the
light value using the AnaLink
principle, i.e. the sensor usually
transmits the value serially on
one channel. When several
threshold values are to be con-
figured for the same light value,
it is possible to transmit the val-
ue on up to 8 channels. If not all
8 channels are used, the unused
channels can remain un-pro-
grammed.
The LUX sensor transmits its
Analink value logarithmically. If
the LUX value is transferred to
an external unit, this unit must
support the following logarithmic
function:
LUX = 0.1 10 (
3 Analink
)

Mounting
As a rule, the G4311120 LUX
sensor should be mounted
where the outdoor light comes
into the room to be monitored,
e.g. on the wall where the win-
dows are to be darkened by
roller blinds. If the sensor is
overshadowed by an overhang
of the roof or similar, this will
increase the darkness at the
sensor, which in connection with
a dimmer function will cause the
dimmer to switch on premature-
ly and to switch off too late.
An optical feedback of the light-
ing to the LUX must be avoided
to the greatest possible extent,
since the light affecting the sen-
sor when the lighting is switched
on can cause a switch on/switch
off cycle.
When selecting the place of
monitoring, environmental
effects (dust, dirt, snow) must
also be taken into consideration,
since in the long run they can
reduce the light sensitivity of the
LUX.
