Light controller controls as "master"
other dimmer actuators
Options: no
yes
•
yes: The object Brightness value of slave is enabled.
•
no: The Light Controller only calculates the setpoint of the connected
lighting for its own output. The status of the brightness value is only sent
via the objects Brightness value or Brightness value/Status.
A brightness difference between the master and the slave can be
implemented by a curve correction. In this way for example, the illumination
for the lighting strip at the window should be darker than the lighting strip
positioned in the middle of the room. This brightness offset (characteristic
correction) should be parameterised in the slave.
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.
Changing brightness during lighting control
Options: fast
medium
slow
individual setting
This parameter determines how fast the lighting changes when the lighting
control commences.
Normally this parameter can be used to select between fast, medium, slow
and individual setting. With master mode only medium, slow and individual
setting are possible to reduce the bus load.
•
fast: The Light Controller starts to control with fast successive
(< 2 seconds) dimming steps in order to reach the setpoint as quickly as
possible.
A fast correction may be necessary if the constant lighting control has
the react quickly to the shade or shadows which result from a blind
which closes quickly.
•
medium: The Light Controller commences with sending dimming steps
at medium speed (< 3 seconds) to achieve the setpoint.
