Commissioning
Basic settings such as the dimming range and switching and dimming reaction of the DALI output or a
group or ballast are made in this parameter window.
Note
References to a central telegram below mean a telegram received via one of the Output x group
objects. The function of the group object relates to the whole DALI output including all the connected
DALI devices and groups.
References to a group telegram below mean a telegram received via one of the Output x – group y
group objects. The function of the group object relates to a DALI group.
References to a ballast or a DALI device below mean a telegram received via one of the Output x –
ballast y group objects. The function of the group object relates to a single DALI device or ballast.
Note
If an individual group or ballast telegram is in progress when a central telegram comes in, the former is
immediately interrupted and the central telegram for the DALI output is executed. Ballasts or groups
which are blocked or under forced operation are not controlled as part of the central telegram, as these
two functions have a higher priority. Note that broadcast commands cannot be used under these
circumstances, which can cause brightness differences on the output.
If all groups and ballasts are controlled with a central telegram and a telegram for a group or ballast
then comes in, this group/ballast is immediately controlled by the group/individual command and no
longer follows the central command.
The last incoming telegram takes priority and is executed.
Note
If a DALI device is controlled individually, it cannot also be assigned to a DALI group. A DALI device can
be controlled either individually via ballast commands or in a group via group commands. Overlapping
DALI groups are not supported.
Initially the DALI gateway assumes that group control is in use. If a ballast is to be individually
controlled, it must be specifically parametrized in ETS. The ballast concerned must be enabled in the
X ballasts parameter window, which is enabled by selecting individual control in the
X DALI configuration parameter window.
If a ballast is assigned to a group but is set to individual control in ETS, or is not set to individual control
but is not assigned to a group, this is referred to as a ballast-group conflict.
A ballast-group conflict is indicated as an incorrect state by a yellow caution field in the i-bus
Depending on which type of control is required (group G or individual S), the device must be assigned to
a DALI group or removed from its existing group.
To control individual DALI devices and groups together, a joint KNX group assignment is required.
