Lightscene control

Functional description
The DALI Gateway is fitted with a test button. If the device is connected
to the mains voltage, each DALI output can be switched on manually
in sequence and then off again.
Once the DALI devices are connected, they can be checked through
a manual test together with the wiring without bus voltage connected.
By pressing the test button (> 2 sec.), the green operating LED is extin-
guished and the test mode starts once the test button has been released.
Channel A is switched on first - all the other channels are switched off.
By pressing the button again (< 2 sec.), the next channel is switched on and
so on. The active channel is indicated by the yellow DALI LED (1 Hz) which
flashes. If you press the test button > 2 sec., the green operating LED starts
to light up and the test mode ends when the test button is released.
The device automatically exits the test mode after 5 minutes if no push
button action is carried out. Once test mode has ended, the channels
automatically revert to the state that existed prior to testing.
Any active scene control, automatic dimming processes as well as timed
processes in dynamic mode continue to run in the background but are not
switched through to the channels during test mode. The channels are
enabled again after exiting the test mode.
Up to 16 lightscenes can be set, stored and retrieved with the DALI-Gate-
way DG/S 8.1. The lightscenes can be set and stored via the ETS or
manually via push button. To prevent the manually adjusted lightscene being
overwritten, each lightscene can be disabled from being overwritten in the
event of an application download.
The lightscenes are composed of the 8 DALI outputs (channels). An indivi-
dual brightness value can be assigned to each channel in a lightscene or
be excluded from the lightscene by the parameter selection "unchanged".
Through setting a scene transitional period, the time can be set individually
per lightscene, after which all the devices in the scene have reached their
lightscene brightness value.
If a scene is dimmed up or down by the central command*), the relative
brightness variations of the individual channels are also stored once the
maximum or minimum brightness values are stored. That means that the
relative brightness values of the lightscene are stored when dimming up or
down.
* Caution: The central command influences all the DALI channels of the DALI
Gateway, not just the channels which are compiled in a lightscene.
