Commissioning
The Light Controller LR/S x.16.1 and the Light Sensor LF/U 2.1 do not
require an additional power supply. The connection to the KNX is sufficient
to enable the Light Controller and Light Sensor functions.
You will require a PC or Laptop for parameterisation with the ETS (from
ETS2 V1.3) and a connection to the ABB i-bus
USB interface. If ETS3 is used a *.VD3 or higher type file must be imported.
The application program Control Dim xf 1-10V/1 (x = 2 or 4 outputs)
provides the device with a comprehensive and flexible range of functions.
The standard settings allow simple commissioning. The functions can be
extended if required.
Each individual output of both Light Controllers features the same technical
characteristics and software functions. It is thus possible, depending on
the application, to freely define every output and to parameterise them
accordingly.
The Light Sensor LF/U 2.1 can be assigned to any output.
If required even two or more Light Sensors can be assigned to an output
(control circuit). In this manner an acceptable constant lighting control is
established in a room even with difficult lighting conditions. A calibration
(setting) of the control circuits with one or more Light Sensors should be
undertaken in the operating range (target brightness). During this calibration
the final conditions which are prevalent in the room must exist as these
reflection and absorption properties directly affect the control circuit
algorithm. The description of the calibration procedure as well as correct
positioning of the Light Sensor can be found in chapter
control.
The following table provides an overview of the functions that are possible
with the Light Controller LR/S x.16.1, the Light Sensor LF/U 2.1 and
the application program Control Dim xf 1-10V/1" (x = 2 and 4 outputs):
