Field Flashing OFF (disabled): 

        

    

Field Flashing and self-excita�on procedure is influenced also by the Keep Alive func�on. The 

“keep alive”

 feature allows to maintain a 

minimum excita�on current even when the Generator frequency drops below the minimum (P.130). The minimum excita�on current value 

can be adjusted using parament P.250; this se�ng must be done based on the power source (set up to 0 if the power is from PMG or 

auxiliary). With “keep alive” enabled (P.250>0), the S2022 will try to keep a minimum excita�on current during the start-up (and during the 

shu�ng down). As default P.250 is adjusted to 5. This means that the S2022, during the start-up  (and shut-down),  will  try  to  keep  the  

excita�on current to 5% of the rated excita�on current (P.000). Once the frequency will be higher the P.130 (Generator minimum frequency), 

the AVR will leave the “keep alive” area and will enter in the V ramp area.

In case the AVR is powered with a PMG or with an external power source the “Keep Alive” func�on has to be disabled (set P.250=0).

With P.250=0 also the Field Flashing is disabled, does not ma�er the bridge posi�on described above.

Above screenshot shows the Field Flashing and the Keep Alive func�ons effects during generator star�ng up and shu�ng down. Once the 

frequency drops below P.130 the AVR ac�vates the keep alive func�on and works in order to maintain the excita�on current to the P.250 

keep alive se�ng (in this case 5%).
