Parameter window Central

In the parameter window Central, the settings for simultaneous control of all lighting groups are
parameterized.
Note
If a central telegram is referred to in the following, this is a telegram, which is received via one of the
communication objects with the name DALI Output. They are the communication objects No. 11 to 29.
The function of the communication object relates to all lighting groups available in the DLR/A.
If DALI devices are connected to the output that is not assigned to lighting groups, they are not
controlled via the central telegram DALI output. In the parameter window Gx: group it is possible to
program the DLR/A, so that all devices, which are not assigned to a group, are automatically assigned
by the DLR/A to group 8. In this way, it is possible to commonly control all connected DALI devices even
without manual group assignment via the communication object DALI output.
If at the time of the incoming central telegram an individual group telegram is implemented, this is
immediately interrupted and the central telegram is executed on the DALI output. If all lighting groups
are controlled with a central telegram and if a subsequent telegram is received for an individual lighting
group, this lighting group will execute the group telegram. The telegram received last has an even
higher priority and is executed.
Central telegrams interrupt the functions Slave, Light control and Staircase lighting of a lighting group.
The lighting groups undertake the central telegram. The functions switch to standby mode and must be
restarted/activated after completion/fulfillment of the central telegram by an ON telegram or activation of
the function.
