WIRING AND CONFIGURATION OF THE ECG
4.3. AstroDIM – autonomous dimming without
external control
4.3.1. Wiring
When the AstroDIM function is selected by providing a
permanent connection (jumper wiring) between line (L)
and the SD terminal of the ECG (see fi gures 21 and 22),
the ECG starts and ends dimming on its own (autonomous
operation). It is controlled only by the mains power switch
and no additional control lines are required.
There is no need to confi gure the ECG before AstroDIM
operation. The ECG starts operating with the default para-
meters of the AstroDIM function when the power is on.
The AstroDIM parameters, e.g. dim levels and fade times,
can be modifi ed via the 3DIM Tool by connecting a PC to
the DA terminals of the ECG via an OSRAM DALI magic
hardware interface.
External wiring between L and the SD terminal can be
avoided if the “AstroDIM/DALI” mode is selected via the
3DIM Tool (see fi gure 23b).
