Commissioning
Slave is controlled via
Options:
This parameter determines where the slave receives its brightness value. This brightness value can
originate externally via the KNX, from one of the other KNX devices or internally in the DLR/A from one of
the first 4 lighting groups.

Object "Brightness value of slave": In this case, the slave evaluates the value received via the object
Brightness value of slave as a control signal for its lighting group.

Group x brightness: In this case, the slave receives its brightness value internally in the DLR/A from
lighting group x. The brightness value is not applied with an offset from the master.

Group x brightness offset: In this case, the slave receives its brightness value internally in the DLR/A
from lighting group x. The brightness value is applied with an offset from the corresponding lighting
group.
Dim period to reach slave brightness
(function slave brightness)
Options:
This parameter determines the time duration, in which the DLR/A sets the brightness value from the
communication object Brightness value of slave or internally from another lighting group for the lighting
group when activating the function Slave.

jump to: All DALI devices of the lighting group immediately switch on with the received brightness
value.

0.7 s...90.5 s: This is the time duration used by the lighting group to dim to the received brightness
value.
If function slave is active (running):

Switch on
Options: no reaction
set function in standby
With activated function Slave, the parameter can be used to define the reaction to an ON telegram
on the communication object Switch or Switch/status.

no reaction: An ON telegram is ignored.

set function in standby: An ON telegram ends function Slave, and the DLR/A carries out the
switch telegram. The function Slave is latent and waits until a renewed activation (standby
state) via the communication object Activate function slave or via a telegram with the value 1 to
the communication object Switch or Switch/status.
