min. physical brightness
individual device adjustment
These parameters define the brightness value, with which each DALI device
of channel A or B is switched on when an ON telegram is received.
If a value to be set is outside the minimum and maximum dimming value
limits, the brightness will be limited to the maximum or minimum dimming
values.
If for example the device is at a brightness value which is not equal to the
switch ON value and it receives an ON telegram, the parameterised switch
ON value is set.
The "last brightness value" parameter setting has the effect that the device
switches on with the brightness value which it had before the OFF command
had been received.
The minimum physical brightness of DALI equipment is the brightness level
which the luminaire can set as the minimum dimming value conditioned by
its physical properties. Typical values for the minimum physical brightness of
ballasts are 1...10%. If devices with different minimum physical brightness
are connected on the channel device, different brightness values are set.
The setting "individual device adjustment" has the effect that with a central
ON command, the devices assume the switch ON value which is set in the
parameter window "Device x" (x = A, B).
Permit channel to be turned on via dim telegram
Option: yes
no
individual device adjustment
If set to "yes", the device can be turned on via the dimming function.
The setting "individual device adjustment" has the effect that the
parameterisation of the individual sample is still valid for this DALI sample, if
a central control received.
Switching off is not possible. This function is not supported by
DALI. It is possible to dim down to the minimum brightness
value. Switching off can be implemented via the OFF command
(e.g. short push of a button).

individual device adjustment
This parameter determines the period which a dimming process requires
when switching on at 0 % brightness to reach the switch ON value. The
same speed applies for switching off from the set brightness value to the
OFF value. This dimming time only affects dimming commands which are
received via ON/OFF telegrams. A soft start or soft stop can be set with this
parameter. With the setting "constant dimming speed", the same speed
