4.3.4 Dimmable energy-saving lamps with L response (leading edge)
This setting allows dimmable energy-saving lamps with L response to be dimmed. No load
detection is performed; dimming is carried out with leading edge instead.
•
The energy-saving lamp always starts with at least 85% output and then, if applicable,
automatically dims down to the minimum brightness after 1 second.
•
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).
•
This configuration is optimal, for example, for OSRAM 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.
Notes:
•
Many types of lamps can cause an overload in L mode, which automatically leads to the
dimming down of the load.
•
Because of impermissible radio interference, some ESLs must not be operated
in L mode.
In both cases, automatic load detection must be selected (i.e. RC mode).
