2.3.1.26 LD0.LEDGGIO1 Indication LED states Color1/Color2
These LED indication points interpret the case when a signal is wired to both the OK
and ALARM inputs, but inverted to the other. This means that the LED toggles
between red and green colors. The default color for ALARM is red and green for OK.
Colors can, however, be reconfigured with a setting parameter.

Figure 2: Signal wired to both OK and ALARM inputs – inverted to the other
If the OK and ALARM inputs are wired to separate indication signals,
the LED will have three legal states and cannot be expressed with one
bit only. In this case, it is possible to combine this LED bit
interpretation with the corresponding value from the other LED state
interpretation.
