Note
If the gateway receives a central switch, relative dimming or Brightness value telegram via a group
object for the DALI output while Slave mode is running, the telegram is executed. The slave goes to
standby. To respond to the master again the group has to receive an ON telegram via the Switch group
object or be reactivated by the Activate fct Slave group object.
Note
The additional function Slave can adopt three operating states:
Additional function Slave is not active: The additional function is deactivated via its Activate fct Slave
group object if a telegram with the value 0 is received. In the deactivated state the group reacts like a
normal group. The properties set in the Group x parameter window apply. In this state, an ON telegram
does not start the additional function. The group only switches to slave state after a telegram with the
value 1 is received on the Activate fct Slave group object.
Additional function is active in standby: The additional function is active but has been interrupted,
e.g. by an OFF telegram. The group is in standby. An ON telegram (telegram on the Switch group
object) retriggers the additional function and the slave starts responding to the Brightness value of slave
group object or internally to its master again.
Additional function running: The Slave function receives its brightness value from the master. This
can be direct, internally from a ballast or group on the output without a KNX connection, or via the
Brightness value of slave group object. The master is assigned in the Group x Slave parameter window
using the Source (slave is controlled via) parameter.
Depending on individual parametrization, the active Slave function can be put on standby by a Switch-
on, Brightness value, Relative dimming or Recall scene command.

Options:
This group object defines whether the dimming time can be changed via KNX.
•
Fixed fade time: Dimming time is permanently set and cannot be changed via the KNX.
•
Can be changed via object "Flexible time for dimming/fade time": Dimming time can be changed via
the KNX using the Flexible time for dimming/fade time group object.
