Note
The additional functions Slave and Light control can assume the following operating states:
Additional function is not active: The additional function has been deactivated, a telegram with the
value 0 has been received. In this state, the DLR/S behaves like a "normal" group-orientated DALI Light
Controller.
In this state, an ON telegram does not start the additional function. Only after a telegram with the value
1 has been received on the communication object Function Activate Slave/Function Activate controller
is it possible to start the additional function.
Additional function is in standby mode: The additional function is active but has however been
interrupted, e.g. by the OFF telegram. The lighting group is in standby mode. An ON telegram (telegram
to the communication object Switch) triggers the additional function again, i.e., Light control operates
and the slave lighting group again responds to the communication object Brightness value of slave.
Additional function running: Light control runs, the Slave function receives brightness values from the
master. With corresponding parameterization of the switching telegrams, the additional functions can be
set to standby mode.
State after download: After a download, the additional functions are active and can be found in
standby mode. Thus, the additional function can be started immediately after a download, without any
additional activation, exclusively with a corresponding ON telegram.
When the corresponding communication object for the status message of the additional function is
enabled via the parameterization, the status of the additional function (activated/deactivated) is sent via
the respective communication object Fct Activate Slave/Status or Fct Activate controller/Status after a
download.
If an additional function is not selected or deactivated, the following parameters apply:
Switch-on value
Options:
If an additional function is enabled, the parameter name changes to Switch-on value (only if addition
function is not activated).
This parameter defines the brightness value, which is used to switch on the lighting group when an ON
telegram is received.
If a value is set which is outside the dimming value range (Maximum dimming value or Minimal dimming
value), the threshold is set as the minimum or maximum dimming value.
If for example, the lighting group is at a brightness value, which is not equal to the switch-on value, and it
receives an ON telegram, the parameterized switch-on value is set.

Previous value: The lighting group is switched on with the brightness value which it had when the OFF
telegram was received.
