Chapter 4 Setup Menus 43
4.14 PFC Manual Mode Menu
This menu allows you to manually operate (connect or disconnect) the PFC
capacitor banks in progressive order by entering commands from the front panel.
The menu can be only accessed via the Setup Change Menu (CHG) if the PFC is
running in Manual Mode (see Section 4.13, PFC Setup).
When in the Manual Mode menu, the present measured power factor value is
displayed in the upper window, the PFC operation status in the flashing middle
window and measured reactive power in the lower window. Depending on the
selected power factor setpoint trigger, the power factor and reactive power are
based on the true RMS measurements or on the fundamental harmonic values.
The PFC operation status reported in the middle window is explained in Table 4-12.
The up/down arrow keys are used as the command keys and act in Manual Mode
as follows:
Switches in a capacitor bank
Switches out a capacitor bank
The capacitor banks are connected and disconnected progressively from the first
controlled bank to the last, following all pre-set switching and re-connection
delays. Whenever a number of the banks with the same size are available, the
PFC will use at each step the bank that has the minimum number of switching
cycles. A new command will not be accepted until the PFC has completed the
previous command, i.e., until the reported PFC operation status is Ready, Full or Idle.
To switch in a capacitor bank:
Ensure that the PFC is ready, and then press and release the up
arrow key.
To switch out a capacitor bank:
Ensure that the PFC is ready, and then press and release the
down arrow key.
To quit the menu:

Table 4-12 PFC Operation Status
Code Operation Status Description
rdY Ready A switching program is complete
ALAr Alarm Operations are stopped by an alarm setpoint
buSY Busy Waiting until a switching delay is expired
FULL Full All capacitor banks are switched in
IdLE Idle All capacitor banks are switched out
NOTE
The Manual Mode commands do not affect the capacitor banks that are defined as
permanently switched banks. These always switch in automatically when the PFC is put into
operation, including in Manual Mode.
