Product and functional overview

The group-orientated ABB i-bus
installation in suspended ceilings or underfloor. Up to 64 DALI devices that can be controlled in 8 lighting
groups may be connected to a DALI output. The DALI power source for the 64 DALI devices is integrated
into the DLR/A.
Control using KNX is implemented exclusively via 8 lighting groups. Only the first 4 lighting groups can be
used for direct constant lighting control combined with 4 Light Sensors LF/U 2.1. Using the function Slave,
any number of lighting groups can be assigned to a master, e.g. controller. A brightness value offset is
available for a slave, e.g. a second lighting strip, to utilize a brightness value that deviates from the master
for every controller group (master). The offset can, for example, be time-controlled or switched off or on
with KNX using an outdoor brightness sensor, so that the room is always lit with the optimum level of
brightness. Furthermore, the function Staircase lighting is available. As an option, the constant lighting
control can be combined with the function Staircase lighting.
Furthermore, setting of 14 light scenes is possible, which can be recalled or stored via 8 bit or 1 bit KNX
telegrams.
The DALI devices connected to the DALI output (max. 64) can also be controlled or recalled (broadcast)
together. This is also possible without previous commissioning (group assignment) via the KNX.
Information relating to a lamp and/or ballast malfunction is available individually for a lighting group or for a
DALI device on the KNX. DALI error messages can be inhibited on the KNX with the assistance of a KNX
communication object.
Via a Test button, connected DALI devices can be commonly (by broadcast) turned on or off for testing.
The brightness value (0...100 %) of the ballast after ballast supply voltage recovery (power on level) is
programmable. The initial DALI address assignment occurs automatically via the DALI Light Controller.
This means that when replacing a DALI device, where DALI addresses are assigned without any gaps the
new DALI device is automatically brought into operation without the need for any auxiliary tools. This
function can be vetoed via a parameter in the application.
Readdressing of the DALI devices and the assignment of the 64 DALI devices into 8 lighting groups is
implemented in the ETS independent Software-Tool, so that for example a facility manger without ETS
knowledge is capable of exchanging and reassigning DALI devices should maintenance be required. Error
states of the individual DALI devices and/or lighting groups are represented graphically. Furthermore,
commissioning of the constant lighting control is simplified. DALI addresses and group assignments can
be deleted and devices can be reset to their supplied state.
The setting of the parameters and allocation of the group addresses is implemented with the Engineering
Tool Software ETS. The most up-to-date version should be used.
