4.3.3 Dimmable energy-saving lamps with RC response (trailing edge)
This setting allows dimmable energy-saving lamps with RC response to be dimmed.
The energy-saving lamp always starts with 100% output and then, if applicable, automatically
dims down to 95% after 3 seconds. After another
30 s the ESL is warm enough and can be
dimmed down to the minimum brightness.
•
Minimum configurable minimum brightness = 1%. With energy-saving lamps, depending on
type, a minimum brightness of 20%...35% is sensible (below that the lamps flicker or go out
completely).
•
If the ESL is switched off in the warm state for less than 30 s, after being switched on again
the heating phase will be shorter.
In this case, the duration of the warm-up phase corresponds to the previous turn-off time.
•
This configuration is optimal, for example, for MEGAMAN lamps.
This produces the following relation between the time elapsed since switching on and the minimum
possible dimming value:
No values are permitted in the hatched area independent of the requested dimming value.
Note:
As connecting an L-load in RC mode could lead to functional problems with the dimmer,
load detection will always be performed as a precaution.
The RC mode will only actually be used when no L-load is detected.
