2.3 DALI installation & features
2.3.1 Simplified installation
The installation of DALI is carried out with commercially available in-
stallation material for 230 V line voltage. The two wires of the five-wire
cables (e.g. NYM 5 x 1.5 mm²) that are not needed can be used for
the DALI interface - regardless of polarity. Thus, no separate bus ca-
ble is required! The ECG and control unit can be operated on different
line voltage phases.
2.3.2 Construction site mode
The ECGs can be switched on or off at any time via the fuse protec-
tion even if there is no controller installed or programmed (basic DALI
function). With ECGs straight from the factory the lighting is always
switched on at 100 % luminous flux.
2.3.3 Benefits of DALI ECG with group assignment
Each ECG in the DALI system can be addressed individually and digi-
tally. Each ECG is assigned an address and group association on
start-up. Each ECG may belong to as many as 16 groups – and to
several groups at the same time. The ECGs can be addressed individ-
ually, in groups or all together. The group assignment can be changed
at any time without rewiring.
2.3.4 Integrated scene memory
Each ECG can store up to 16 light values, irrespective of the group
assignments. Fading from one scene to the next is synchronous. This
means that all ECGs start fading to the new scene at the same time
and finish at the same time (by varying the dimming rate).
2.3.5 Status report from the ECG
The control unit can query the status of each and every ECG. This
enables a lamp fault (or failure) or the brightness of a lamp to be de-
termined, for example. The feedback capability of the OSRAM DALI
ECG is crucial in association with complex bus systems (EIB, LON) in
building management systems (e.g.: the OSRAM BASIC checks for
lamp faults and can forward these via a potential-free message con-
tact; the OSRAM Advanced provides the option of analysis by means
of the HPT (Hand Programming Tool, see www.osram.com/ecg-lms).
