Commissioning
This parameter defines the brightness value for the Turn off brightness function, i.e. the brightness
at which the output switches off when it receives an OFF telegram.
Values set outside the thresholds (maximum brightness/minimal dimming value) are automatically
adjusted to the maximum or minimum.
Group object
"Activate fct Turn off brightness"
(enable in "Output functions")
Options: Yes
No
Turn off brightness can be activated/deactivated via the KNX using the Activate fct Turn off
brightness group object. This means a timer can be used, for example, to set the lighting to a
parametrizable turn off brightness at night instead of switching it off.
•
Yes: The output evaluates the Activate fct Turn off brightness group object. If the gateway
receives a telegram via this group object on the output, the system reacts as follows:
1: The turn off brightness is set to the parametrized brightness value. The Turn off brightness
function is activated. An OFF command will then apply this brightness value instead of OFF,
0%.
0: The brightness value is set to 0. The Turn off brightness function is not activated and an OFF
command switches the system off via the Switch group object, applying a brightness value
of OFF, 0%.
•
No: The output does not evaluate the Activate fct Turn off brightness group object. The system
always switches off at the parametrized turn off brightness.
Note
The Turn off brightness function can be applied to the whole DALI output, all ballasts and all
groups. It must first be enabled in the X Output x functions parameter window along with the
Activate fct Turn off brightness group object.
To define whether the output, a ballast or a group reacts to the Turn off brightness function on
the output, make the settings in the relevant parameter window: A Output, Ballast x or Group x.
