Staircase timer function
The Staircase timer function that can be parameterized separately can be used for implementing time-
controlled staircase lighting or functionally similar applications. The Staircase timer function must have
been enabled in the "Groups - [x] group name – Staircase timer function" parameter node to make the
required communication objects and parameters visible. The Staircase timer function can be
parameterized only for the groups 1 ... 16.
The Staircase timer function is controlled via the "Start/Stop Staircase timer function" communication
object and depends on the "Switching" object of the group (cf. figure 24). This permits a 'parallel
operation' of time and normal control, with always the last command being executed.
A telegram to the "Switching" object during an active Staircase timer function ends the staircase
lighting time prematurely and sets the switching status according to the object value (time delays taken
into account). Similarly, the switching state of the "Switching" object can be overridden by a Staircase
timer function.
In combination with a disable function a time-independent permanent lighting function can also be set
up (cf. "Disable function").
The Staircase timer function can be extended by a pre-warning function. The brightness of the DALI
group can be reduced during the pre-warning. In acc. with DIN 18015-2, the pre-warning function is
designed to warn anyone present in the staircase that the lights will go out shortly.
