Maximum brightness value
Options:
This parameter defines the maximum brightness value, which the lamps of the lighting group can assume.
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 minimum dimming value, the maximum brightness value is set equal to the mini-
mum brightness value.
If the function Burn-in lamps is activated, the lamp group will be operated only with 0 % (OFF) or 100 %
brightness, regardless of this setting.
If a brightness value is received via the communication objects Brightness value, Brightness value/status
or Brightness value of slave, which is above the defined maximum dimming value, the maximum dimming
value is set.
The maximum brightness value also applies in the functions Staircase light, Scene and Sequence.
Note
The maximum and minimum dimming values selected for the lighting group are also valid with a central
telegram via the communication objects of the DALI output.
Example: Lighting group 1 is parameterized with a maximum dimming value of 80 %; lighting group 2 is
parameterized with 90 %. If the DGN/S receives a central telegram in this constellation to set the
brightness value to 100 %; lighting group 1 is set to 80 %, and lighting group 2 is set to 90 %.
Allow switching ON via dim telegram
Options:
This parameter defines the switch on response of the lighting group at dimming.
yes: Switch ON using the dim telegram is allowed.
no: Switch ON using the DIM telegram is not allowed. The lighting group must be switched on in order
to be dimmed.
Allow switching OFF via dim telegram
Options:
This parameter defines the switch off response of the lighting group at dimming.
yes: Switch OFF via a DIM telegram is allowed.
no: Switch OFF via a DIM telegram is not allowed. The lighting group must be switched off explicitly
via an OFF telegram. Independent dimming down is not possible.
