4.2.4.3 Status LED
Two single-colour status LEDs can be used as orientation lighting or as button-press display. In
the "neutral position" device version, the LED can also be used as a status indicator with the
"rocker switch" operation concept. In this case, the LEDs have their own 1-bit communication
objects for activation.
The status LEDs are configured on their own parameter pages. The "function" parameters on
these parameter pages define the LED display functions. In the 1-gang push-button bus
coupler, both LEDs always perform the same display function. In the 2-gang device, the LEDs
can perform different functions independent of each other.
The following LED functions are available for selection in the configuration...
-
"always OFF"
This setting can only be selected for the rocker and button functions. The corresponding
status LED is always off in this parameter setting.
-
"always ON"
This setting can only be selected for the rocker and button functions. The corresponding
status LED is always on in this parameter setting (orientation lighting).
-
"button-press display"
This setting can only be selected for the rocker and button functions. At the same time, the
device switches on a status LED for the "Light period of status LED for button-press
indicator" as soon as a corresponding rocker switch or button is pressed. The period is
configured jointly as button-press display for all status LEDs on the "General" parameter
page. The status LED lights up when the rocker or button is pressed even if the telegram is
transmitted by the device only when the button or rocker is released.
The dependency of the status LED to the rocker switches or buttons depends on the device
variant. (see page 19)...
- "1-gang switch position": Both status LEDs (left and right) light up on pressing button 1,
- "1-gang neutral position": Both status LEDs (left and right) light up on pressing the rocker
switch 1 or buttons 1 and 2,
- "2-gang switch position": The left status LED lights up when on the button 1, the right
status LED lights up on pressing button 2,
- "2-gang neutral position": The left status LED lights up on pressing the rocker switch 1 or
buttons 1 and 2, the right status LED lights up on pressing the rocker switch 2 or the
buttons 3 and 4.
i
The KNX function "Scene extension with storage function" can particularly affect the status
LED allocated to the actuated button. If the status LED is configured to "button-press
display", the LED always lights up for the configured light period when the button is pressed
(1...5 s). When transmitting a storage telegram after pressing the button for a long time (> 5
s), the status-LED is additionally activated for 3 seconds in order to indicate that the
storage instruction was transmitted to the bus.
-
"Status indicator (via LED object)"
This setting can only be selected for rocker switch functions. At the same time, the status
LEDs can indicate the state of a separate 1-bit communication object. It is possible to
switch the LED on or off statically via the 1-bit object value received (object value "0" =
OFF, "1" = ON).
After a bus reset or after ETS programming, the value of the LED object is always "0".
-
"Inverted status indicator (via LED object)"
This setting can only be selected for rocker switch functions. At the same time, the status
LEDs can indicate the state of a separate 1-bit communication object. It is possible to
switch the LED on or off statically via the 1-bit object value received (object value "1" =
OFF, "0" = ON).
After a bus reset or after ETS programming, the value of the LED object is always "0".
