Enable Group object
"Activate fct Turn off brightness"
Options:
Linked group object:
On receipt of an OFF command from the Switch group object, the Turn off brightness function sets the
lighting to a turn off brightness instead of switching it off (brightness value 0).
•
Yes: The group object is enabled. The group object is evaluated in the output, group or ballast in order
to switch to the turn off brightness on receipt of an OFF command.
•
No: The group object is not enabled.
Whether a ballast or group evaluates this group object is defined for each ballast/group in the
corresponding Ballast x or Group x parameter window.
Note
The Relative dimming function via the Dimming group object and the Set brightness value function via
the Brightness value group object are unaffected.
Note
Whether the group or ballast evaluates the telegram received is defined in the corresponding group or
ballast parameter windows. The Activate fct Turn off brightness group object can therefore influence any
or all of the ballasts or groups on the output.
Note
The function can be used e.g. to prevent the lighting from switching off completely at night in retirement
homes or hospitals, so that there is always a basic brightness – the turn off brightness.
