ROTATING DIODE FAULT
The regulator is constantly measuring the fluctuations that occur in the excitation current, when a
variation occurs above a percentage of the average current, and the actuation time exceeds a
defined time the regulator signals an alarm of the occurrence of the fault.
➢ Percentage reference of the average excitation current: 30%.
➢ Time for protection action: 5 seconds.
➢ Signaling: Alarm Led constantly lit in Cyan (Blue-green).
