Minimal brightness value
Option:
min. physical brightness
5%
…
70%
With this parameter, the minimum brightness value is defined which the
DALI devices should assume when dimming or when setting a brightness
value. The absolute minimum brightness value (min. physical brightness),
which the ballast lamp combinations can assume is manufacturer-specific
and is typically between 1 % and 5 %. If a minimum brightness value is set
which exceeds the maximum brightness value, the minimum brightness
value is set equal to the maximum brightness value. If the “Burn in Lamps”
function is activated, the lamp will be operated only with 0 % (off) or 100 %
brightness regardless of this setting.
If a brightness value is received via the “Brightness value/Status”
communication object, which is below the defined minimum brightness
value, the minimum brightness value is set.
The set minimum brightness value in the device continues to be valid with
central commands.
Maximum brightness value
Option:
100%
…
30
With this parameter, the maximum brightness value is defined which the
DALI devices should assume when dimming or when setting a brightness
value. If a maximum brightness value is set which is lower than the minimum
brightness value, the maximum brightness value is set equal to the minimum
brightness value. If the “Burn in Lamps” function is activated, the lamp will be
operated only with 0 % (off) or 100 % brightness regardless of this setting.
If a brightness value is received via the “Brightness value/Status”
communication object, which is above the defined maximum brightness
value, the maximum brightness value is set.
The set brightness value in the device continues to apply for central
commands received for channel A and channel B.
Permit channel to be turned on via dim telegram
Option:
yes
no
If set to "yes", the channel can be turned on via the dimming function.
Switching off is not possible. This function is not supported by
DALI. It is possible to dim down to the minimum brightness
value. The device must be switched off via the shutoff
command (e.g. short push of a button).
