Overview

The DALI Light Controller DLR/A 4.8.1.1 requires, in addition to the KNX voltage, a light controller supply
voltage to generate the DALI voltage for full function capability. The light controller supply voltage range
can be found in
alone is sufficient for programming the application in the DALI Light Controller. Thus in an office
environment it is possible to pre-program the DLR/A exclusively using the KNX voltage without having to
resort to a light controller supply voltage (a 230 V AC/DC supply).
For commissioning of the Software Tool, in which the compilation of the lighting groups and the calibration
of constant lighting control can be implemented, the light controller supply voltage must also be connected.
The properties of the lighting groups are independent of each other and can be programmed individually. It
is thus possible, depending on the application, to freely define every lighting group and to parameterize
them accordingly.
The first 4 lighting groups have a special feature, as they can be used for constant lighting control together
with the connected Light Sensor LF/U. If required even two or more light sensors can be assigned to a
lighting group (control circuit). In this manner an acceptable constant lighting control is established in a
room even with difficult lighting conditions. The description of the calibration procedure as well as correct
positioning of the light sensor can be found in chapter
In the DLR/A, it is possible to parameterized a lighting group by using the copy and exchange function and
to transfer the parameters to another lighting group. The copy and exchange function is described in detail
at Copying and exchanging parameter
The following table provides an overview of the functions used by the DLR/A 4.8.1.1 and those possible
with the application program Control Dim Groups 4f DALI/1.
