When the excitation current is set to the
rated value, a voltage dip is observed in
excitation current limit when the
limitation is activated and the current
limit is reached.
4.2.3 - Special type of use
WARNING
The excitation circuit F+, F- must not be
left open when the machine is running:
this will irreparably damage the AVR.
