12. Navigate to Menu then to Operating Mode and select your operating
mode.
This screen shows the Operating mode. Verify your
steps are configured properly before making Operating
mode selections:
• Manual (mode = 0) – This mode disables all
automatic operating modes. Manual mode is the
default configuration. All capacitor steps have a
default configuration of auto.
• FILO (mode = 1) – This mode of operation
switches the capacitor steps on and off in first-in,
last-out (FILO) order. That is, the first step on is
the last step turned off. This is most useful when
all the capacitor steps are of similar size.
• Balanced (mode = 2) – This mode counts the
number of opening operations on each capacitor
step and switch-capacitor steps to balance the
number of opening operations equally across all
of the employed capacitor steps. This mode is also
most useful when all of the steps are of similar
size.
• Best Fit (mode = 3) – This mode selects capacitor
steps to be switched on and off to most closely
achieve the target power factor and kVAR needs
of the system. When the system’s kVAR needs to
increase, the available step or steps with the
closest (aggregated) kVAR rating is added. On
decreasing kVAR demand, steps are switched off
in similar fashion.
