4.8.1 Staircase lighting with function Light control
With the DALI Light Controller there is a possibility of using the function Staircase lighting in conjunction
with the constant lighting control. This means constant lighting control is undertaken during the operation
of function Staircase lighting. This combination is very efficient from an energy-efficiency point of view. In
addition to the limited switch on duration of the lighting, it is only controlled with the brightness value that is
actually necessary to light up the room to a sufficient level.
The control is only used during the operation of function Staircase lighting. During the dimming-up,
dimming-down and during the basis brightness running time, the lighting control is suspended and is in
standby.
During switching on or retriggering of the staircase lighting, the switch on brightness of the function
Staircase lighting is used switching on.
Should the function Staircase lighting be deactivated, the lighting group has a "normal" control function. In
the same way, the lighting group with deactivated function Light control behaves like a lighting group with
function Staircase lighting. If both functions are deactivated, the lighting group is a "normal" lighting group.
If lighting control is inactive and is activated via communication object Activate function controller, the
function Light control initially goes to standby. The staircase lighting is not restarted or retriggered in this
case. Only after the next switch on via the communication object Switch will the lighting control start to
control during the staircase lighting time. A prerequisite for this is that the staircase lighting time has been
ended and the function Staircase lighting is in the dimming down time, basis brightness hold time or
subsequently in standby.
The function Staircase lighting has a higher priority than the additional function Light control with regard to
the parameterized behavior for incoming KNX telegrams. The behavior should be defined in parameter
window - Gx Staircase lighting.
