Instruction Manual 51
4.3.2.1.- FUNCTION SELECTION
Use this screen ( Figure 53 ) to select the functions of the AFQ-4W:
Figure53: Function selection screen.
Harmonic filtering: Current harmonic neutralisation. (This option is enabled by
default.)
Phase balancing: Balancing of the current between phases. (This option is not
enabled by default.)
Reactive compensation: A function that allows the shifting of the cos
Φ to be
compensated. (This option is not enabled by default.)
Function priority Order: The AFQ-4W allows the functions to be prioritised in
the event of filter current saturation by overload. When the “Function priority
order ” function is disabled, priority is given to the current harmonic filtering and
reactive compensation and overload balancing are penalised. If “Function
priority order” is activated, priority is given to current balancing between phases
and reactive current compensation, ahead of harmonic neutralisation. (This
option is not enabled by default.)
