Maximum brightness value
Options:
This parameter defines the maximum brightness value that the ballast or group can adopt. This value is
stored in the DALI devices and thus applies for all functions. If a maximum brightness value is set which is
below the minimal dimming value, the DG/S sets it to the minimum.
If the Burn-in lamps function is activated, the group, ballast or output is operated at 0% (OFF) or 100%
brightness, regardless of the minimal dimming/maximum brightness setting.
If a brightness value above the defined maximum brightness value is received via one of the Brightness
value group objects, the maximum value is adopted.
The maximum brightness value also applies with dimming and with the Staircase lighting, Slave and
Scenes functions.
Note
The DALI output itself has no separate maximum brightness value. The minimal dimming/maximum
brightness values defined for the group or ballast remain applicable even on receipt of a central
telegram via the Output x group objects.
Example: Group 1 is assigned a Maximum brightness value of 80%, Group 2 90% and a ballast, 85%. If
the DG/S receives a central telegram Set brightness value at 100%, these group and ballast settings will
not change.
Turn on brightness (Switch fct)
Options:
This parameter defines the brightness value used to switch on the ballast, group or DALI output when an
ON telegram is received.
Values set outside the thresholds (maximum brightness/minimal dimming value) are automatically adjusted
to the maximum or minimum.
If the ballast, group or DALI output receives an ON telegram while at a brightness value other than the turn
on brightness – e.g. due to dimming – it adopts the turn on brightness.
•
Previous value: The ballast, group or output switches on at the brightness value it was switched off at
by the Switch group object.
