Indicator light
Description Function
LED green Indicates status of mains and output
voltage
The LED is off during programming.
ON: Mains voltage present, device operating normally
(I < I
Ovl
)
OFF: Mains voltage absent
LED red Indicates overload/short-circuit current.
The LED lights up when the output
current exceeds the overload limit
(I > I
Ovl
). For SV/S 30.640.5.1, overload
and short-circuit current values apply to
the total current, I = I

Indicates present bus current
If a current value exceeds/falls below
the indicator value by +/-
5 % for at
least 110 ms, the LED comes ON/goes
OFF.
Example, SV/S 30.640.5.1:
LED No. 2 (200 mA) lights up if the
output current exceeds/stays at
210 mA for 110 ms. The LED goes off
if the current falls below 190 mA for at
least 110 ms.

Triggers and indicates a bus reset.
This function can be triggered only
when mains voltage is applied.
Operating one line with two power
supplies:
when the mains supply fails, the Reset
button on the affected device does not
function.
Reset button: Pressing the button for > 2 seconds triggers a
reset. The line shorts. Pressing the button again
during a reset has no effect (no reaction, no
retrigger, no interrupt, etc.)
ON: After pressing for > 2 secs. or for the duration of
the reset (20 s) after receiving the object value.
ON: After 20 s reset
Flashes: At 4.8 Hz while being pressed
Indicates a KNX telegram AN: Receiving telegram
OFF: Stand-by mode
Indicates a communication error on the
bus ON: The LED comes ON for 1 second and is
retriggerable if there is a transmission error or if a
telegram fails or is incomplete (e.g. “BUSY”,
“NAK” (receipt not correct)).
OFF: Device working normally
Please note
Individual LEDs may flash during downloads or while the application is being unloaded.
