Description
Behaviour when receiving a
dimming command (4-bit)
immediate on
The change from 0% to 100% or
100% to 0% takes place within
max. 1 s (in very quick
increments), but can be
interrupted by a stop command
(release button).
soft on with dimming time 1
soft on with dimming time 2
soft on with dimming time 3
The change from 0% to 100% or
100% to 0% takes place within
the preset dimming time in
correspondingly lower
increments.
Behaviour when receiving an
absolute value (8-bit)
immediate on
The received dimming value is
adopted immediately (max.
delay 1 s).
soft on with dimming time 1
soft on with dimming time 2
soft on with dimming time 3
The change from the new
dimming value takes place
within the preset dimming time
proportionately to the change in
value.
Example with dimming time 1 =
12 s: Change from:
- 0 to 100% or 100 to 0% in 12 s
(= 100% of 12 s)
- 25 to 50% or 50 to 25% in 3 s
(= 25% of 12 s)
etc.
Switch-on Value
Value before previous switch-
off
The last dimming value before
switching off is saved and
restored
minimum value
The configured minimum
brightness is applied.
100%
10%, 20%, 30%
40%, 50%, 60%
70%, 80%, 90%
The dimmer adopts the selected
value after it is switched on.
Here again the configured
minimum dimming value needs
to be taken into account.
