Setting parameters
Actuators KNX R4 16 A and KNX R8 16 A
• Version: 28.05.2020 • Technical changes and errors excepted.
In
Switch-off early warning
you can set a "flashing" which starts shortly before the
switch off. Define the warning time and the on/off rhythm.
6.3.5. Block function
The "Block function" menu item only appears if "Use blocking object" is selected in the
settings for the switch function channel: yes’ is selected.
The output channel can be blocked by a blocking telegram. Here it is defined what hap-
pens during the block, when bus voltage is restored and after the block. Manual oper-
ation is not possible when the block is active.
The function can be used, for example, for a light that switches on when a "panic but-
ton" (= trigger for blocking function) is pressed and can no longer be switched off.
6.3.6. Scenes
A group address for scenes
must be filed in the KNX system to control the scenes.
The input object ‘Channel - call/save scenes’ of the actuator is linked to this group ad-
dress.
A scene is
called
, then the
scene number
is communicated to the actuator. The state
stored in the actuator for this scene number is switched.
If the scene
saving
function is used, then the switch state is saved for this scene num-
ber in the actuator.
The "Scenes" menu item of the actuator only appears if "Use scenes" is selected in the
settings for the switch function: yes’ is selected. The actuator has
8 scene memories
for switch states.
Activate a scene save point.
Assign a scene number to the scene save point. The switch state stored in the actuator
is retrieved/stored via this scene number. Make sure that every scene number is used
only once per drive channel.
