4.2.4.6.2 Dimming function
For each rocker or each button with the function set to "dimming" the ETS indicates a 1-bit and
a 4-bit object. Generally, the push-button sensor transmits a switching telegram after a brief
press and a dimming telegram after a long press. In the standard parameterisation, the push-
button sensor transmits a telegram for stopping the dimming action after a long press. The time
needed by the push-button sensor to detect an actuation as a long actuation can be set in the
parameters.
The status LEDs can be configured independently . (see chapter 4.2.4.7.1. Functions of the
status LED).
Single-area and dual-area operation in the dimming function
In the rocker function, the device is preprogrammed for dual-area operation for the dimming
function. This means that the push-button sensor transmits a telegram for switch-on after a brief
press and a telegram for increasing the brightness after a long press of the left button
("brighter"). Similarly, the push-button sensor transmits a telegram for switch-off after a brief
press and a telegram for reducing the brightness after a long press on the right button
("darker").
With the button operation concept, the device is preprogrammed for single-area operation for
the dimming function. In this mode, the push-button sensor transmits on each brief press ON
and OFF telegrams in an alternating pattern ("TOGGLE"). After a long press, the push-button
sensor transmits "brighter" and "darker" telegrams in an alternating pattern.
The parameter "Command on pressing the button" or Command on pressing the rocker" on the
parameter pages of the buttons or rockers defines the single-surface or dual-area operation
principle for the dimming function. For the rocker and also for the button function, the command
issued on pressing the button or rocker can basically be selected at the user's discretion.
i
If the actuator can be controlled from several sensors, a faultless single-area operation
requires that the addressed actuator reports its switching state back to the 1-bit object of
the button or rocker and that the 4-bit objects of the push-button sensors are interlinked.
The push-button sensor would otherwise not be able to detect that the actuator has been
addressed from another sensor, in which case it would have to be actuated twice during
the next use in order to produce the desired reaction.
Advanced parameters
For the dimming function, the push-button sensor can be programmed with advanced
parameters which are hidden in the standard view for greater clarity. If necessary, these
advanced parameters can be activated and thus be made visible.
The advanced parameters can be used to determine whether the push-button sensor is to cover
the full adjusting range of the actuator with one dimming telegram continuously ("Increase
brightness by 100 %", "Reduce brightness by 100 %") or whether the dimming range is to be
divided into several small levels (50 %, 25 %, 12.5 %, 6 %, 3 %, 1.5 %).
In the continuous dimming mode (100%), the push-button sensor transmits a telegram only at
the beginning of the long press to start the dimming process and generally a stop telegram after
the end of the press. For dimming in small levels it may be useful if the push-button sensor
repeats the dimming telegram in case of a sustained press for a presettable time (parameter
"Telegram repetition"). The stop telegram after the end of the press is then not needed.
When the parameters are hidden ("Advanced parameters = deactivated"), the dimming range is
set to 100 %, the stop telegram is activated and the telegram repetition is deactivated.
Full-surface operation with the dimming function
When a rocker is used for dimming, the device needs some time at the beginning of each
operation in order to distinguish between a short and a long operation. When full-surface
