How does the OSD react to DALI commands?
The table below shows the reaction of the OSD and the
luminaires behind it on the most common DALI commands
in comparison with a “normal” driver .
All DALI commands given to the OSD that affect the
output level will start the occupancy timer . A single DALI
command will set the output level only for a limited period
(the occupancy timer period) if an area is not occupied .
Lights will switch off after this period (or go to background
level if set) .
You need to repeat the DALI command to keep lights on a
certain level . The repetition time must be shorter than the
occupancy timer period set in the OSD .
