Art. No. DS 4092 TS
4.2.4.1.2 Push-button function Dimming
If the push-button is set to the "Dimming" function, the ETS indicates a 1-bit object and a 4-bit
object. Generally, the device transmits a switching telegram after a brief press and a dimming
telegram after a long press. In the standard configuration, a telegram for stopping the dimming
process is transmitted when releasing the push-button after a long press. The time needed by
the device to detect an actuation as a long actuation can be set in the parameters.
Single-surface and double-surface operation in the dimming function
In the standard setting, the single-surface dimming function is preset in the ETS. In this mode,
the device transmits ON and OFF telegrams in an alternating pattern ("TOGGLE") on each brief
press. After a long press, the "brighter" and "darker" telegrams are transmitted in an alternating
pattern. The parameter "Command on pressing the button" defines the single-surface or double-
surface dimming function.

If the addressed actuator can be controlled from control sections, a faultless single-surface
operation requires that the actuator returns its switching state to the 1-bit object of the
push-button. In addition, the 4-bit objects of the control sections must be interconnected via
an identical group address. Otherwise, the operating function of the push-button would not
be able to detect if the actuator had been controlled from another control section.
Advanced parameters
The push-button has advanced parameters for the dimming function 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 process is to be
divided into several small levels (50 %, 25 %, 12.5 %, 6 %, 3 %, 1.5 %).
In the continuous dimming mode (100%), the device transmits a telegram only at the beginning
of a 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 device 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.
