Mode Function
BASEPF Gen-set power factor is maintained at
constant level adjusted by the setpoint
Base PF.
PF-IM/EX Gen-set power factor is controlled so, that the
mains power factor is maintained constant at
the level adjusted by setpoint Import PF
ANEXT BASEPF Gen-set power factor is maintained at
constant level given by the analog input
PFCtrl:AnExBPF
ANEXT PF-IM/EX 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.
