Enable function "Blocking"
Options: no
yes
The object Block is enabled with this parameter. The function of the output
can be blocked here via this object so that it cannot be changed via the bus.
The current brightness value of the output is frozen. All commands with the
exception of forced operation and the reactions to bus voltage failure and
recovery are ignored. Incoming telegrams are not stored intermediately or
processed in the background. The information is lost.
An activation of the blocked operation during dimming up and dimming down
of the still active staircase lighting and switch or scene function is initially not
carried out. Only at the end of the dim process is the output blocked and the
brightness frozen. A block during the staircase lighting or control function on
the other hand leads to an immediate blocking of the output and freezing of
the brightness value. After unblocking, the staircase lighting function
continues with dimming (prewarning).
If lighting control or slave operation were active before the block they will be
re-established.
Forced operation has a higher priority than the block. With activated forced
operation the block function can be activated or deactivated.
In this way the current blocked state is available after forced operation as
would be the case without activated forced operation.
Enable characteristic adjustment
Options: no
yes
•
Yes: The parameter window Characteristic adjustment is enabled.
In this the dim characteristic (lighting dependent on the brightness value)
can be changed.
The special properties of the characteristic adjustment are defined in
the
X: Charact. Adj.
With the characteristic adjustment the curve of the ballasts can be
changed to suit requirements. Furthermore, using constant lighting
control the brightness value of a second lighting strip (slave) can be
increased or reduced in dependence on a master output (lighting strip).
In this case the brighter lighting strip should be selected as the master,
i.e. the slave output is controlled as darker by the characteristic
adjustment.
For further information see:
Note
The characteristic adjustment acts directly on the 1-10 V output and not
on the objects Master: Slave brightness value or Status brightness value.
This means that a characteristic adjustment must be set in the output of
the Light Controller or in the external slave.
In a master/slave combination of LR/S x.16.1 and DG/S 1.1 or DG/S 8.1,
a characteristic adjustment may not be transferred to the DG/S.
