• Can a DALI ECG belong to more than one group at the same
time?
Yes. Each DALI controller can belong to up to 16 groups.
• Where are the data for the group assignments and light
scene values stored?
They are stored directly in the internal EEPROM of the ECG.
• Are the data in the ECG lost if there is a power failure?
No, the data are permanently stored in the ECG. They are retained
even if the power failure is prolonged.
• What happens if an ECG fails?
The ECG simply has to be replaced and adjusted to the appropri-
ate settings (the procedure depends on the control unit).
• What happens if a control unit is faulty?
If the DALI interface voltage is lost, all ECGs take on the so-called
"system failure level" (ECG factory setting: 100 % light).
• Can DALI be integrated in superordinate building manage-
ment systems (e.g. EIB or LON)?
Yes, by using gateways or control units with the appropriate inter-
face.
• Is DALI a competitor to EIB or LON?
No, DALI is only a subsystem of the building management system
for controling the lighting.
• Can 1…10 V components also be incorporated in a DALI
lighting control system?
Yes, by using DALI to 1…10 V converters.
• Can existing 1…10 V lighting systems be upgraded with a
DALI controller?
Yes, a DALI to 1…10 V converter is needed for each 1…10 V lumi-
naire group (e.g. DALI CON 1…10 SO).
• Can the wiring of the DALI ECG be checked on a building
site?
This depends on the control unit used. DALI ECGs that are still in
their factory setting always produce 100 % light when the mains
voltage (with protection) is applied.
