The ABB i-bus KNX DALI Light Controller DLR/A 4.8.1.1 is a KNX device surface-
mounted (SM) device for installation in suspended ceilings or underfloor.
The DALI Light Controller can in conjunction with the application program Control
Dim Groups 4f DALI/1 integrate devices with DALI interfaces into a KNX building
installation. The connection to KNX is implemented via a bus connection terminal.
The 4 sensor inputs for the Light Sensor LF/U together with the first 4 lighting groups
of the DALI Light Controller can be used for a constant lighting control.
The DALI output can be used to connect up to 64 DALI devices. The 64 DALI
devices should be assigned into 8 lighting groups with the ETS independent
Software Tool. Control of the 64 DALI devices via KNX is exclusively group-
orientated.
The fault status (lamps and ballasts) of every individual DALI device can be sent via
a coded communication object on the KNX.
In the DLR/A, a staircase lighting time curve can be set. Constant lighting control
can be combined with a staircase lighting time curve, so that constant lighting
control can be implemented during the staircase lighting time curve. The 8 lighting
groups can be integrated into scenes as required. Using a 1 bit or 8 bit KNX scene
telegram, these scenes can then be recalled or stored via the KNX. Furthermore, a
master/slave function with integrated offset is available that can be used to integrate
further lighting groups or dimming actuators into the lighting control.
Using central telegrams, all the DALI devices connected to a DALI output can be
commonly controlled via the KNX (broadcast).
The DLR/A is a DALI control device (master) and requires an AC or DC auxiliary
power supply. The DALI power source for the 64 DALI devices is integrated into the
DALI Light Controller. In order to control the DALI devices manually or via the KNX,
the KNX voltage and the auxiliary voltage (light controller supply voltage) must be
applied. Should one of these voltage sources be absent, the DALI devices can no
longer be controlled. The behavior of the DALI devices on voltage failure can be
parameterized.
All the DALI devices connected can be commonly turned on or off via manual
operation on the device.
