4.4 Connecting lighting groups using the ELC bus
If SmartDrivers are connected using DALI C0, all connected lights form a
lighting group. This means that all settings, such as light target values and
switch-off delay time, apply to all lights, as does all instances of a presence
detector being triggered.
This grouping is not ideal for many room configurations: If a presence de-
tector detects a person in an open-plan office, it may be sufficient to illu-
minate only part of the room. A dimmer orientation light would be sufficient
for the rest of the room.
This very option is provided by the connection of lighting groups using the
ELC bus, which also increases the number of lights that can be controlled.
The ELC bus does not enlarge a single lighting group, instead it networks
up to 10 lighting groups.
Like other bus networks, the ELC bus also has a chain topology. To pro-
tect against malfunctions, both ends of the connection must be equipped
with terminating resistances. This is done using the ELC bus configuration
switch.
