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.

Stairc. light. activate/status: The communication object Stairc. light. activate/status is available for the
lighting group. The function Staircase lighting can be activated (telegram with value 1) and deactivated
(telegram with value 0) via this communication object. Should the function Staircase lighting not be
activated, the lighting group is a "normal" lighting group. The following communication objects for the
function Staircase lighting (Stairc. light. permanent ON and Warning) have no effect for the "normal"
lighting group. After deactivation of the function Staircase lighting via the communication object Stairc.
light. activate/status the function Staircase lighting runs to completion and thereafter is in standby.
Note
If the function Staircase lighting is used, it is highly recommended that this additional object be enabled
as only this communication object allows the function Staircase lighting that has been deactivated to be
reactivated. The sending behavior can be set in parameter window
lighting, page 90.
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 With the value 0, the forced operation is rescinded and the lighting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 with 1-bit control::

Brightness while object value = 1
(forced operation = active, ON)
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.
