Chapter 5 PFC Setup and Operation 48
PFC will not take into account the status of the digital input. The second setpoint
will not even appear in the PFC setup menu.
If you want to use different target setpoints and switch them depending on the
time schedule or another external condition, specify the operational setpoints as
SP1-2. In this event, both SP1 and SP2 setpoint ranges will be available for
setup, and should be defined for proper operation. The PFC will always consider
the status of the digital input in order to select an appropriate setpoint range:
open = SP1, closed = SP2. Before running the PFC, configure the digital input as
a status input (see Section 4.3).
Power Factor Setpoint Ranges
The setpoint range limits are designated as L.PF1 (low target power factor) and
Hi.PF1 (high target power factor) for the first setpoint, and as L.PF2 and H.PF2
for the second setpoint.
The allowable range for either power factor setpoint is 0.5 (inductive) to -0.5
(capacitive). The default setpoint range is 0.80 to 0.98.
The target power factor limits are always specified for the I (first) and IV (fourth)
quadrants with positive (imported) active power, regardless of the location of the
instrument on the source or load side. The PFC will automatically account for the
direction of power flow providing full four-quadrant operation.
If both target power factor limits are specified for the same quadrant, the high
power factor limit should never be less than the low limit. If the target limits are
being set for two quadrants, the lagging (inductive) power factor should be
specified as the low limit and the leading (capacitive) one as the high target limit.
Whenever these relations are not fulfilled, the instrument will automatically adjust
the high target power factor to the low target limit.
Reactive Power Setpoint Ranges
The setpoint range limits are designated as L.rE1 (low target reactive power) and
Hi.rE1 (high target reactive power) for the first setpoint, and as L.rE2 and H.rE2
for the second setpoint.
The allowable range for either reactive power setpoint is -10,000 (capacitive) to
10,000 (inductive).
The target reactive power limits are always specified for the I (first) and IV (fourth)
quadrants with positive (imported) active power, regardless of the location of the
instrument on the source or load side.
The high reactive power limit should never be less than the low limit. Whenever
this is not fulfilled, the instrument will automatically adjust the high target reactive
power to the low target limit.
PFC Setpoint Operate Delay
The PFC setpoints will not respond to the poor power factor or kvar if the time
that the measured value is outside the setpoint range is less than the user-
