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. Since this operation concept
performs switching and dimming, it can be used autonomously without any additional
operating elements. Hence, the push-button in this case, can be configured for another
control function.
The rotary sensor differentiates between different operations (e.g. switching dimming brighter,
afterwards dimming darker or STOP / faster or slower operation for the operation concepts
"Dimming Comfort...") based upon the time that the rotary knob stands still after a completed
operation. The "Time for standstill after each movement" is configured in the ETS and should
not be selected too short in order to avoid unintended control operations - particularly during
fast operations. If the device detects additional operations immediately after a rotary movement
(time not yet elapsed), it evaluates the continuing movement of the rotary knob and executes
further reactions as described if necessary. The time for standstill detection is retriggered for
each rotary knob movement.
Dimming without OFF telegram
When operating the rotary knob, a 4-bit dimming telegram (relative dimming) with a step width
of 100 % is already transmitted after the first notch (minimum rotation angle) with this operation
concept. By using the maximum dimming step width, the entire brightness range can be
operated. The direction of rotation specifies the dimming command (Brighter / Darker). As soon
as the rotary knob is no longer operated, the device transmits a stop telegram after the
configurable "Time for standstill after each operation" in the ETS has elapsed, which stops the
dimming process.
This operation concept 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.
i
If the direction of rotation changes without a break during an operation, the rotary knob
immediately transmits a stop telegram to the bus. The device evaluates this operation as a
wrong operation and thus transmits no further telegram at the end of the rotary movement.
i
The rotation angle (number of notches during a rotary movement) and the speed of rotation
is not evaluated by the device in the operation concept "Dimming without OFF telegram".
