NOTE: if the auxiliary power supply is missing, the STOP state information is lost; as a consequence, the START
and STOP management described above only applies when the D-Vo is running under one of the following
operating conditions:
1. separate power and auxiliary supply, i.e. auxiliary supply always on even when the generator is stopped;
2. auxiliary supply shunted from power supply and generator running at full rpm (with residual auxiliary supply
>20Vac).
