Art. No. SC 1000 KNX
4.2.4.2.12 Disabling function
Disabling function configuration
With the 1-bit communication object "B. Key disabling", the operating areas of the push-button
extension module can be partly or completely disabled. During a disable, the rockers or buttons
can also temporarily execute other functions.
An active disable applies only to the functions of the rockers or buttons of the push-button
extension module. The status LED or other functions of the device are not affected by the
disabling function.
The disabling function and the pertaining parameters and communication objects are enabled if
the parameter "Disabling function ?" in the parameter node "Push-button extension module ->
Disable" is set to "Yes".
You can parameterize the polarity of the disabling object. In case of polarity inversion (disabled
= 0 / enabled = 1), the disabling function is not activated immediately after a device reset (object
value = "0"). There must first be an object update "0" until the disabling function will be
activated.
i Telegram updates from "0" to "0" or from "1" to "1" on the "button disabling" object remain
without effect.
Presetting the reaction at the beginning and end of a disable.
If the disabling function is used, the reaction of the push-button extension module on activation
and deactivation of the disabling function can be preset separately in the parameters
(parameter "Reaction of push-button sensor at the beginning / end of disabling"). In this
connection it is irrelevant which of the operating areas is influenced and possibly also locked by
disabling. The push-button extension module always shows the configured behaviour.
The disabling function must have been enabled in advance.
o Set the parameter "Reaction of pushbutton sensor at the beginning / end of disabling" to
"No reaction".
The push-button extension module shows no reaction at the beginning and at the end of
disabling. The sensor only adopts the state as provided for by the "Behaviour during active
disabling".
o Set the parameter "Reaction of pushbutton sensor at the beginning / end of disabling" to
"Internal scene recall scene 1 …8".
The push-button extension module recalls one of the up to 8 internal scenes. Scene
storage is not possible.
o Set the parameter "Reaction of pushbutton sensor at the beginning / end of disabling" to
"Reaction as button >> X << / >> Y << when pressed / released".
The push-button extension module executes the function assigned to any "target button" in
non-disabled state. Target buttons are operating buttons of the push-button extension
sensor which may be configured for rocker or for button operation. The target buttons are
configured separately for the beginning (X) of for the end (Y) of disabling. Both buttons of a
rocker are treated as two separate buttons.
The action configured for the respective target button is executed. If the configuration of the
target button has no function or no telegram on pressing or releasing the button, or if a
module button is configured without the suitable extension module connected, then there is
also no reaction to disabling or to re-enabling. If the selected target button is part of a
configured rocker, the behaviour preset for the respective rocker side (rocker X.1 or X.2)
will be used. The telegrams are transmitted to the bus via the required communication
object of the target button.
The following table shows all possible telegram reactions of the push-button extension
module with respect to the target button function.
