Note
These three additional functions, Slave, Sequence and Staircase light can assume three operating
states:
Additional function is not active: The additional function has been deactivated via its communication
object Select additional function; a telegram with value 0 has been received. In this state, the DGN/S
behaves like a "normal" group-orientated DGN/S.
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 Select additional function 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. With an ON telegram
(telegram to the communication object Switch), the additional function is again triggered, i.e., the Se-
quence or the Staircase lighting runs, the slave lighting group again responds to the communication
object Brightness value of slave.
Additional function runs: The Sequence or the Staircase light runs, the function Slave 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 stand-
by mode. Thus, the additional function can be started immediately after 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 Activate additional function/status after a download.
If an additional function is selected, the following parameters apply for the time period in which the addi-
tional function is inactive.
Brightness value when turned ON
Options:
The parameter name changes if an additional function is selected: Brightness value when turned ON (only
if additional function is not activated).
This parameter defines the brightness value, which is used to switch on the lighting group when an ON te-
legram is received.
If a value is set, which is outside the dimming value range (Maximum brightness value or Minimal bright-
ness value), the threshold is set as the minimum or maximum brightness 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.
last value: The lighting group switches on with the brightness value, which it had when the OFF tele-
gram was received.
