— How can DALI ECGs be addressed?
They can be addressed individually, in groups or all
together.
— Can I receive feedback from the DALI ECGs?
Yes, all device settings as well as the device status
(lamp malfunction, for example) can be queried.
— Can a DALI ECG belong to several groups at once?
Yes. Each DALI control gear can belong to up to
16groups.
— Where are the data for group membership and
scene light values saved?
It is saved directly in the ECG internal EEPROM.
— Are data in the ECG lost in the event of power
failure?
No, the data are permanently stored in the ECG. They
are also retained after a longer power failure.
— What happens when an ECG fails?
The ECG just needs to be replaced and equipped with
the corresponding individual settings (the procedure de-
pends on the control unit used).
— What happens if a control unit is defective?
If the DALI interface voltage is lost, all ECGs implement
a so-called “system failure level” (factory setting: 100 %
light).
— Is it possible to integrate DALI into superordinate
building management systems (e.g. KNX or LON)?
Yes, using gateways or control units with the
corresponding interface.
— Is DALI a competitor of KNX or LON?
No, DALI works as a sub-system of the building
management system to control light.
— Can 1…10-V components be integrated into a DALI
light management system?
Yes, using a converter from DALI to 1…10 V.
— Can existing 1…10-V light systems be upgraded
with a DALI control unit?
Yes, only one converter from DALI to 1…10 V is
needed for each 1…10-V luminaire group (e.g. DALI
CON 1…10 SO).
— Can the wiring of the DALI ECGs be inspected at
the building site?
This depends on the control unit used. DALI ECGs
new from the factory are always set to 10 % light when
applying the mains voltage (with fuse).
— Which insulation should be used for the DALI
control line?
The DALI control line must be approved for mains volt-
age (as with the 1…10-V interface).
— Can existing 1…10-V control lines be used for
DALI?
Yes (line rated for mains voltage).
— What is the maximum permissible length of the
control line?
Maximum 300 m is allowed between the control unit
and the farthest DALI consumer.
— Can control and supply lines be routed together?
Yes, a 5-x-1.5-mm
2
NYM cable can be used, for
example.
— What should the cable cross section of the con-
trol line be?
— Up to 100 m: min. 0,5 mm
2
— From 100 m to 150 m: 1,0 mm
2
— From 150 m: 1,5 mm

— Can anyone develop a DALI control unit or ECG?
Yes, there are no restrictions. Using the DALI logo,
however, is only allowed for members of the DALI
Group.
— What happens when DALI ECGs from different
manufacturers are used in a single system?
The devices are DALI-compliant if they bear the DALI
logo. However, bear in mind that as with the 1…10-V
technology, various fi lament preheating times in the
ECGs from different device manufacturers lead to
deviating lamp switch-on times.
— Can control units from different manufacturers be
combined?
No, only the DALI ECGs can be exchanged in a control
system, not the control components.
— Can a maximum and minimum luminous fl ux limit
be set?
Yes, the values can be changed/limited with the
corresponding control unit.
