Via the "Duration of long operation", the time is specified from which a long button press
is recognized, and the object values are reset. The first level must be set again with a
press of the button. Any time from 0.3 to 3 seconds can be set. A typical value after which
a jump-back to level 1 is set at 0.4 s.
12.18.2 Common parameter – Method of dimming
Options
You can switch between the two dimming versions "Start-Stop dimming" and "Step-wise
dimming" via this parameter.
"Start-Stop dimming" means that exactly two 4-bit telegrams for dimming are always sent
out. For triggering of a dimming command, a telegram with the information "Dim by 100%
brighter" or "Dim by 100% darker". When the button is release, the second telegram is
sent out with the "Dimming stop" information. Hence, a connected dimming actuator can
be halt at any time during the dimming phase.
The second dimming procedure is the step-wise dimming ("Dim stop is not sent" setting).
For step-wise dimming, a defined value, e.g. "Dim brighter by 6.25%" is always sent out
for triggering of a dimming command. This dimming procedure can be utilized if dimming
sensor and actuator are install in different lines. In this case, telegram delays can occur
through a coupler and thus varying brightness values if multiple dimming actuators are to
be activate in different lines.
12.18.3 Extended parameter – Working mode of the buttons for switching
Options
The "Working mode of the button for switching" application determines whether switching
on or switching off occurs via the right or the left side of the button. Using the behavior
"Alternating on/off" always switches between ON and OFF. That means, for example, if
an ON telegram was last sent out, then a renewed operation of the rocker switch will
trigger an OFF telegram. If the button is operated again, an ON telegram will be sent
again, etc. The button thus always remembers the last state and then switches over to
the other value.
This also applies for values that are received via the associated 1-bit communication
object. This means that if an ON telegram was sent out for the last button operation,
thereafter an OFF telegram was received via the communication object, the next
operation of the button will send out an ON telegram. It must be observed here that the
S-flag (writing) of the communication object is activate.
