Art. No. SC 1000 KNX
based on the position feedback of the Venetian blind or rolling shutter actuator. In selection
operation, the bar graph visualises the blind/shutter height or alternatively the slat position
depending on which element was last selected for operation in the display area. In direct
operation the bar graph always displays the blind/shutter position only.
The position orientation of the bar graph (ascending, descending) depends on whether the slat
control or blind/shutter control was selected. In the shutter/blind control, the bar graph falls from
the top to the bottom when the position of the activated shading system becomes greater.
Similarly, the bar graph rises when the position becomes less. In the slat control, the bar graph
orientates itself from the bottom to the top. In this case, the bar graph rises when the position of
the activated slats becomes greater. Similarly, the bar graph falls when the position decreases.
At full-scale deflection of the bar graph, the maximum shutter/blind position has been reached
or the slats are completely closed. If the bar graph does not show any deflection, the shutter/
blind is completely retracted or the slats are completely opened.
The bar graph is always visible and normally supplements the status indication by status value
and status icon.
Objects
A channel of the function Venetian blind/shutter (Step/Move/Step)" has up to 4 communication
objects depending on the type of configuration blind/rolling shutter etc...
-
"D.Output channel x - Venetian blind (Step)" (1-bit transmitting):
Short-time telegrams are transmitted to the bus via this object after a short touch of the
sensor element. This causes any ongoing drive runs to be stopped. Alternatively, blinds/
shutters or slats are activated briefly since the drive is being activated from the "Stop"
state. KNX blind or shutter actuators then execute the configured short-time operation
(Step).
-
"D.Output channel x - Venetian blind (Move)" (1-bit transmitting):
Long time telegrams (up, down) are transmitted to the bus via this object after a long press
of the sensor element. This enables activated blinds/shutters of shading systems to be
controlled until the end positions. KNX blind or shutter actuators additionally execute the
configured long-time operation (Move).
A short time telegram (see object "D.Output channel x - Venetian blind (Step)") can
interrupt ongoing drive runs of the long time operation (Stop) thereby enabling a blind/
shutter to be stopped at any desired point.
-
"D.Input channel x Venetian blind feedb. blind/shutter height" (1-byte receiving):
Through this object the device can receive a position feedback for the blind/shutter height
that a Venetian blind or shutter actuator transmits, for example. The status value, status
icon and bar graph for the blind/shutter height visualisation are influenced as a result.
Consequently, the feedback object must always be configured properly so that the status
indications of the channel element work correctly.
The feedback of the position value must be transmitted by the "actively transmitting"
actuator.
-
"D.Input channel x Venetian blind feedb. Slat pos." (1-byte receiving):
Through this object the device can receive a position feedback for the slat position that a
Venetian blind actuator transmits, for example. The status value, status icon and bar graph
for the slat visualisation are influenced as a result. Consequently, the feedback object must
always be configured properly so that the status indications of the channel element work
correctly.
The feedback of the position value must also be transmitted by the "actively transmitting"
actuator here.
