External selection of auto reclosing mode

The auto reclosing mode can be selected by use of available logic function blocks.

Below is an example where the choice of mode, ARMode=3ph or ARMode=1/2/3ph, is

done from a hardware function key at the front of the IED, but alternatively there can

for example, be a physical selector switch on the front of the panel which is connected

to a binary to integer function block (BTIGAPC).

The connection example for selection of the auto reclosing mode is shown in Figure
