Art. No. SC 1000 KNX
Status elements
The display area contains different display elements (figure 30) that are influenced by ETS
parameters. A name can be assigned to each KNX channel in the ETS (A). This text name is
centred in the display element for display whereby controllable KNX functions are identified for
the user (e.g. "ceiling spot"). In addition, a status value (B) can be displayed below the name,
which displays brightness values in plain text ("0...100 %") depending on the object value of the
dimming value feedback of the dimmer actuator addressed. After a device reset, the display
shows "---%" until a feedback object value of the status text is received.
Similarly to the status value, a symbol (C) can be displayed in the lower display area. The
"Lighting" icon is always used. The characteristic of the status icon, in which the brightness
state of the controlled KNX channel can be clearly read (
†
, changes depending on the
dimming status: Lighting OFF or low brightness,
‡
: Lighting maximum brightness, interim
values by symbol with fewer light beams).
The status value and icon can be omitted optionally.
In the channel function "dimming (Start/Stop)", a bar graph (D) is displayed in the sensor
element. This bar graph displays brightness values in graphic form based on the object value of
the dimming value feedback of the dimmer actuator addressed. The bar graph rises when the
brightness of the activated lighting becomes greater. Similarly, the bar graph falls when the
brightness decreases. At full deflection, the maximum brightness is set. If the bar graph shows
no deflection, the lighting is switched off.
The bar graphs is always visible and normally supplements the status indication by status value
and status icon.
Objects
A channel of the function "dimming (Start/Stop)" has 3 KNX communication objects...
-
"D.Output channel x - Dimming (Switching)" (1-bit transmitting):
Switching telegrams are transmitted to the bus via this object after a short touch of the
sensor element. A connected lighting system, for example, is switched on as a result. KNX
dimmer actuators then normally set the configured switch-on brightness.
-
"D.Output channel x - Dimming (Start/Stop)" (4-bit transmitting):
Dimming telegrams are transmitted to the bus via this object after a long press of the
sensor element (increment 100%). A connected lighting system is dimmed as a result. A
stop telegram is triggered via this object by releasing the sensor element.
-
"D.Input channel x Dimming (Feedb. brightness value)" (1-byte receiving):
Through this object the device can receive a brightness value feedback that a dimmer
actuator transmits, for example. The status value, status icon and bar graph 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 brightness value must be transmitted by the "actively transmitting"
actuator.
i
The object "D.Output channel x Dimming (Feedb. brightness value)" interprets received
values on the basis of the KNX data point type 5.001 (Scaling). The decimal data values
0...255 are evaluated as percentages 0...100 % and displayed in the device display.
