Color Temperature Control Block
Color Temperature Control| Block function block for
the control element Block
Color Temperature Control; the control element must be connected to this
function block. See
Block Presence and Presence
General. With this function block, the brightness and color temperature are controlled over the time of day. This allows the color or warmth of the light to be controlled along a curve over the day. A color temperature control is a function used in many lighting and display systems to adjust the color rendering. It allows control over the color temperature, which influences the perceived "warmth" or "coolness" of the perceived "warmth" or "coolness" of the light or screen. The curve itself is set on the control element and stored in the controller, see Color light control. From it the block calculates the current value every minute and outputs it on the outputs Percent and Color temperature K - but only as long as the input Automatic is not equal to 0. The time switch and the presence settings of the control element also switch this input. |
Inputs |
||
| HE | Brightness | Optional. Measured brightness in Lux. If this input is connected, additional settings are shown on the control element. Via these settings it can be selected that, for example, when Present the automatic mode is only switched on when it is dark. The thresholds "Threshold bright" and "Threshold dark" are set on the control element. Not connected: no distinction is made between bright and dark, the selection is not shown on the control element and switching times and presence values are always executed. |
| RS | Reset runtime | Optional. Reset counter on-time. The change from 0 to not equal 0 is evaluated, the counter is set to 0. Not connected: the counter is only reset via the Reset button on the control element. |
| AU | Automatic | Automatic mode of the color light control. Not equal to 0 releases the curve, 0 blocks it. While blocked, the outputs Percent and Color temperature K are no longer changed by the block and the lighting stays as it was last set. The input is written by the control element, by its time switch and by its presence settings and can additionally be set from the program or from the bus. Not connected: the automatic mode is never active. |
Outputs |
||
| PR |
Percent |
Brightness 0-100 %. Updated by the automatic mode every
minute and written when operating by hand. |
| FK | Color temperature K | Color temperature in Kelvin. Updated by the automatic mode every minute and written when operating by hand. |
| SP |
Status Percent |
Optional. Feedback of the brightness from the luminaire. It is shown on the control element and determines when the switch-on time is counted. Not connected: the value of the output Percent applies. |
| SK | Status Color temperature | Optional. Feedback of the color temperature from the luminaire, it is shown on the control element. Not connected: the value of the output Color temperature K applies. |
| LZ | Runtime | Accumulated switch-on time in hours. It is counted as long as the brightness is not equal to 0. The value is retained across a restart. |
| WT | Maintenance | 1 as soon as the switch-on time has reached the maintenance limit set on the control element, otherwise 0. If no limit is entered there, the output stays 0. |
