6.3  Power Factor regula�on (PF)

The AVR controls in automa�c mode the power factor at generator terminals. The PF func�on is ac�ve when P300= 1, and I002= 5; once the 

52G digital input (generator in parallel) is closed, the PF func�on starts to work. Generator current reading is necessary to use this func�on. 

Be aware of the correct PF reading.

6.4  Reac�ve power regula�on (VAR)

The AVR controls in automa�c mode the reac�ve power at generator terminals. The VAR func�on is ac�ve when P300= 1, and I002= 6; once 

the 52G digital input (generator in parallel) is closed, the VAR func�on starts to work. Generator current reading is necessary to use this 

func�on. Be aware of the correct VAR readin
