WIRING AND CONFIGURATION OF THE ECG
4.1. DALI ® – digital addressable lighting interface
4.1.1. Wiring
For DALI
® operation, the 3DIM ECG (OPTOTRONIC ® for
LED modules or POWERTRONIC ® for HPD lamps) is con-
nected to the mains and to a DALI ® controller or DALI ®
bus. The SD terminal is left unconnected. The LED module
or HPD lamp is connected to the output terminal of the
respective ECG.
Note: DALI ® connection has to be considered at the inter-
face between luminaire head and pole.
Up to 64 DALI ® electronic control gears can be controlled
via a 2-wire control line – individually, jointly or in up to
16 groups. All of them are connected in parallel to the
two wires (see chapter 4.1.2.). DALI
® connections are not
polarized. Therefore, plus and minus poles do not have
to be checked.
The lighting can be switched and dimmed via the DALI ®
control line. Additional status information can be read out
and exchanged between the ECG and the control unit. The
type of status information that can be exchanged depends
on the ECG or the control unit.
More details about DALI ® can be found at the following
websites (or in the corresponding standard IEC 62386):
