PF control modes in SPtM or SPI application 
 
ProcCtrlSingle: PF ctrl PtM 
Gen-set power factor is maintained at 
constant level adjusted by the setpoint 
Base PF. 
ProcCtrlSingle: PF ctrl PtM  
Gen-set power factor is controlled so, that the 
mains power factor is maintained constant at 
the level adjusted by setpoint Import PF 
ProcCtrlSingle: Import PF, 
I/E Qm-meas 
Gen-set power factor is maintained at 
constant level given by the analog input 
PFCtrl:AnExBPF 
Analog input: PFCtrl:AnExBPF 
Gen-set load is controlled so, that the mains 
power factor is maintained constant at the 
level given by the analog input PFCtrl:AnExI/E 
– I/E power factor is measured by controller 
on auxiliary CT input or by analog input.
