Setting for the phase reversal function (see description for function group MAIN)
for electrical machines in pumped storage power stations.
Phases to be reversed (A-B swapped, A-B swapped or A-B swapped) may be set
separately for each end.
At the same time the display MAIN: Phase reversal activ will be
triggered unless the setting is No swap.
