Special Dimming Mode (RL-LED)
Normally, trailing edge phase (RC) is set automatically for LED or energy-saving lamps (ESL/CFL).
You can also dim special lamps in leading edge phase mode (RL-LED). To do this set the dimming mode in the ETS.
You should select this mode in the following cases:
-
If the manufacturer of the light expressly recommends the leading edge phase or RL operating mode.
-
If the lowest dimming value in the automatically selected operating mode is still too bright, and this operating mode is not prohibited by the manufacturer of the light. Switching to dimming operation mode RL-LED is particularly useful if the dimming range was previously deemed too small (Dimming Range).
The setting is activated once the application has been loaded. The inductive properties of the load are also checked in this operating mode, and the system will switch to the RL operating mode if necessary.
Load detection is normally performed when switching on or dimming (value > 0) for the first time after the mains voltage has been restored.
