The diagram in Figure 5 illustrates how commands and references are managed both for magnetization
and for demagnetisation. Using a DCREG2, the phase of counter-energizing, which is essential to
suppress residual magnetization, is no more available.
If relays are used instead of a PLC, relays controlled by DCREG2's digital outputs may be equipped with
AC or DC coils, provided that the maximum allowable power value is not exceeded. Because of weak
current values (milliAmperes), use low capacity relays to make sure that contacts properly close.
