Dimming (4 Bits)
You can use the relative dimming function to dim the output up or down relative to its current value. The step value of the brightness change and the dimming direction are defined by the telegram value.
Telegrams for the relative dimming function are received via the dimming object. After a relative dimming telegram has been received, a new nominal value is calculated using the current value, the received dimming direction and the received step value.
The preset dimming time for relative dimming to 100% is 5.4 s.
Example:
A: Minimum brightness in % = 22%, current output value = 25%
|
Dimming brighter telegram with a step value of 12.5% |
→ |
New nominal value: 25% + 12.5% = 37.5% |
|
Dimming darker telegram with a step value of 25% |
→ |
New calculated nominal value: 37.5% – 25% = 12.5% Actual value: 22% (A: Minimum brightness in %) |
The limit values A: Minimum brightness in % and B: Maximum brightness in % cannot be violated in the case of relative dimming.
