2.4.10 DALI parameters in the ECG
The following data can be saved in the DALI ECG when a
DALI system is started up:
— Group membership of the DALI ECG (maximum
16groups, multiple assignment possible)
— Individual addresses for directly addressing each ECG
(max. 64)
— Light values for the individual scenes (max. 16)
— ECG parameters that determine the device behavior:
— Dimming speed
— Behavior in case of failure of the voltage at the
interface (“system failure level”)
— Behavior in case of mains voltage return
(“power-on level”)
In addition to the options named above, it is always possi-
ble to address all devices together, even without program-
ming the devices beforehand (construction site function).
2.4.11 Transmission wire requirements
When selecting the cable, it must be ensured that the en-
tire voltage drop does not exceed a value of 2 V at 250 mA
on the control line. Mains supply and control line may also
be routed in the same cable as with 1…10 V. Thus, a 5-core
NYM cable can be used to connect the DALI ECG with no
problem. The maximum total line length of a DALI system
(control unit and connected ECGs) should not exceed
300 m. The required cable cross section for the control line
can be determined according to the following formula:
The following is used as a basis for fi nding the cable cross-
section (transmission and supply cable):
Note
Due to the different technical states of the DALI interface in
control units on the market and the different local condi-
tions for installation, limiting the entire line length used in
the system to 300 m is recommended.
