ABB i-bus KNX
Commissioning
The gateway has a Staircase lighting function which can trigger or stop individual groups or ballasts via
individual Switch telegrams.
As the function and the parameter window for the group and the ballast are identical, only the group is
referred to below. Group can be substituted with ballast.
Each group can be parametrized with its own individual staircase lighting sequence. This can have two
switch-off levels – a basic brightness and a turn off brightness. The lighting can switch to or from the turn
off brightness via KNX, e.g. depending on the time (day/night). This makes it possible to program a
nighttime mode in retirement homes or hospitals so that the lighting does not switch off completely at night.
When staircase lighting mode is active, the effects of other KNX telegrams on the staircase lighting, such
as brightness value, relative dimming or scene recall, are parametrizable. The reaction on KNX bus
voltage recovery can be parametrized, as can staircase lighting triggering and extension (pumping up).
Note
If the gateway receives a central Switch, Relative dimming or Brightness value telegram via a group
object for the DALI output while Staircase lighting mode is running, the telegram is executed. The
staircase lighting goes to standby and its sequence is re-executed by the next ON command on the
Switch group object.
The staircase lighting can also be completely deactivated via the Activate fct Staircase lighting group
object or a forced operation.
Note
The additional function Staircase lighting can adopt three operating states:
Additional function Staircase lighting is not active: The additional function is deactivated via its
Activate fct Staircase lighting group object if a telegram with the value 0 is received. In the deactivated
state the group reacts like a normal group. The properties set in the Group x parameter window apply.
In this state, an ON telegram does not start the additional function. The group only switches to staircase
lighting state after a telegram with the value 1 is received on the Activate fct Staircase lighting group
object.
Additional function is active in standby: The additional function is active but has been interrupted,
e.g. by an OFF telegram. The group is in standby. The additional function is retriggered by an ON
telegram (a telegram on the Switch group object), i.e. Staircase lighting is running.
Additional function active and running: The Staircase lighting function is running and processes the
timer program.
State on download and KNX recovery: This can be programmed in the Staircase lighting parameter
window for the group.
Depending on individual parametrization, the active Staircase lighting function can be put on standby by
a Brightness value, Relative dimming or Recall scene command.
