Figure 18: Rotation angle and dimming step widths in segments during a fast rotary knob
operation
(here with ETS dimming step width 6 %)
T
Parameter "Time for standstill after each movement"
<T slow operation: Dimming step width according to ETS parameter
>T fast operation: dimming step width dependent on rotation angle
The rotary knob distinguishes between slow and fast control operations by counting the number
of notches within a time period (T). The time period is defined directly by the parameter "Time
for standstill after each movement" and retriggered for each new movement. If the device
counts three notches within the time period, it evaluates the control operation as fast and
switches over from the fixed dimming step width according to ETS parameter to the dimming
step width dependent on rotation angle. Otherwise, it is a long control operation that is
retriggered and executed with each new notch.
The operation concept "Dimming Comfort without OFF telegram" only outputs relative dimming
commands. Thus, only a 4-bit communication object is available. Switching telegrams are not
transmitted by the rotary knob to the actuator in this configuration.
Dimming Comfort with OFF telegram
This operation concept functions in the dimming process just like the concept "Dimming Comfort
without OFF telegram", the only difference being that the device can also switch off the
activated actuator by means of a rotary knob operation. For this purpose, the rotary knob
evaluates a brightness value feedback of the dimmer actuator. The behaviour of the device
when switching off is identical to the operation concept "Dimming with OFF telegram".
