3.11.3 Operating Mode of the LED Indicators
For each of the freely configurable LED indicators, the operating mode can be
selected separately. This setting will determine whether the LED indicator will
operate either in energize-on-signal (ES) or normally-energized (NE) mode,
whether it will be flashing and whether it will be in latching mode. Latching is
disabled either manually via setting parameters or by an appropriately
configured binary signal input (see Section 3.12, (p. 3-62)) at the onset of a
new fault, signalized by the onset of a general starting, or of a new system
disturbance, depending on the selected operating mode.
Therefore the operating modes turn out to be the 2³=8 possible combinations of
the following components:
●
flashing / continuous,
●
energize-on-signal (ES) / normally-energized (NE),
●
updating / latching with manual reset,
in addition to these there are the following 4 operating modes:
●
energize-on-signal (ES) with reset after new fault (flashing / continuous)
and
●
energize-on-signal (ES) with reset after new system disturbance (flashing /
continuous),
so that there are 12 possible operating modes in total.
