Functional description
The dynamic mode can be set individually for each channel. Timed bright-
ness characteristics can be set and retrieved when required.
If the operating mode is set to dynamic mode, the channel is able to
implement a simple staircase lighting function as well as special lighting
sequences for a daylight simulation. Only the communication object
“Channel X On / Off” is available in this operating mode. The dimming
characteristic can be set with the following parameters (see 4.3.2.2).
Fig. 7: Dynamic mode - Timed progression of the dimming range
Any values can be set for the starting, hold and switch OFF values in order
to implement specific dimming sequences e.g. daylight imitation for a ligh-
ting sequence in a greenhouse or background lighting on the staircase.
This background lighting could look as follows: The corridor is always illumi-
nated with the switch OFF value e.g. 10% (background lighting). If someone
presses the light in the corridor, the lighting is dimmed to 80% for 8 minutes
and then to 10% again.
The minimal and maximal threshold cannot be parameterised in the dynamic
mode. The limitation is predefined by the start value and the turn-off value.
This must be taken into consideration during the parameterisation of the
dynamic course.
