Commissioning

Warning staircase lighting: The communication object Warning staircase lighting is available for the
lighting group. During the dimming time, additional warning is possible by setting the communication
object Warning staircase lighting to 1. Thus, for example, a pushbutton LED can be controlled or a
warn signal initiated which informs concerning the impending staircase lighting switch-off. If the
dimming down phase is parameterized with Jump to, no Warning staircase lighting is displayed.

Activate stairc. light./Status: The communication object Activate stairc. light./Status is available for the
lighting group. The Staircase lighting function can be activated (telegram with value 1) or deactivated
(telegram with value 0) via this communication object. Should the Staircase lighting function not be
activated, the lighting group is a "normal" lighting group. The following communication objects for the
Staircase lighting function (Staircase light. permanent ON and Warning) have no effect for the
"normal" lighting group. After activation of the Staircase lighting function via the communication object
Activate stairc. light./Status, the Staircase lighting function runs to completion and thereafter is in
standby.
Note
If the Staircase lighting function is used, it is highly recommended that this additional communication
object be enabled, as only this communication object allows the Staircase lighting function that has
been deactivated to be reactivated. The Status sending reaction can be set in
Gx Staircase
Enable function Forced operation
Options:
With this parameter, the lighting group can be enabled for forced operation.

1 bit control: A 1 bit Forced operation communication object is enabled. If the DALI Light Controller
receives a telegram with the value 1 via this communication object, the lighting group of the DALI Light
Controller is forcibly operated. With the value 0, the forced operation is rescinded and the lighting
group is once again enabled. The following parameters appear if 1 bit control has been
parameterized:

Options: 100 % (255)
99 % (252)
...
0 % (off)
The brightness value applied for switching on the lighting group during activated forced operation
can be parameterized with this parameter. Forced switch off of the lighting group is also
parameterized.
