WIRING AND CONFIGURATION OF THE ECG
The StepDIM parameters (power-on level, dim level
and dim fade time) are preset by OSRAM and stored in
the ECG. Notes on the factory settings can be found in
chapter 3.1.
For exact factory settings, please refer to the datasheet
of the respective ECG.
The factory settings can be modifi ed by the user via the
3DIM Tool. In principle, the power-on level can be set low-
er than the dim level. The minimum dim level, however, is
limited by the ECG.
Note: “Low” signal means the SD port fl oating, neither
neutral nor phase are connected to this port.
