Green led
One red LED:
- Lights up simultaneously with the green led
when the continuous operation threshold is
reached for more than 90 s and the excitation
current is reduced to the continuous
operation threshold. It is used to set the
excitation current ceiling
- Turns off when the excitation current is less
than the setting value (< 110% In)
- Flashes when the excitation current is
above the continuous operation threshold
during less than 90 s.
Green LED stays on,
- flashes when the excitation current has
reached the ceiling in < 10s with PMG
excitation.
- ftays on if Iexc = I Shutdown.

If the overload protection is activated, a
voltage drop possibly exceeding 10% of
the reference voltage will be observed.

During load shedding, an overvoltage is
observed, which will disappear in a few
seconds.
