Power Factor. This value is the calculated result of dividing the Real Power (W) value by the Apparent
Power (VA) value. See Equation 4.
Φ = ÷ =

Operating Status. The Operating Status controls and indicators include three buttons and three
corresponding indicators. Operating Status buttons are labeled PF, VAR, and OFF. Clicking the PF button
changes the color of the adjacent PF indicator to green and causes the BE2000E to maintain the desired
power factor regulation point. The power factor regulation point can be set within the range of 0.6 lead to
0.6 lag. Clicking the VAR button changes the color of the adjacent VAR indicator to green and causes the
BE2000E to maintain the desired var regulation point. The var regulation point can be set within the range
of 100 percent absorb to 100 percent generate. Clicking the OFF button changes the color of the adjacent
OFF indicator to red and disables power factor and var regulation.
Operation of the Operating Status controls is determined by the status of the contacts connected across
the BE2000E Var/PF Control terminals (52J, 52K). When these contacts are open, the Operating Status
controls are enabled. Closing the contacts at terminals 52J and 52K disables the Operating Status
controls and interrupts regulation of vars or power factor until the contacts are opened again.
Setpoint - Voltage (V). This setting field can be used to enter the desired generator output terminal
voltage. The voltage setpoint can also be entered at the Setting Adjustments screen, Setpoint tab,
Automatic Voltage Regulator (AVR) - AVR Setpoint (V). The background color of this field is green when
operating in AVR mode and power factor and var regulation is disabled.
Setpoint - Current (A). This setting defines the field current setpoint when operating in FCR mode. The
current setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Field Current
Regulator (FCR) - FCR Setpoint. Current values from 0 to 3 Adc may be entered in increments of 0.01
Adc. The background color of this field is green when operating in FCR mode.
Setpoint - Var (% of nom.). This setting determines the level of generator vars maintained by the
BE2000E when operating in var mode. The var setpoint can also be entered at the Setting Adjustments
screen, Setpoint tab, Reactive Power Control (VAR) - VAR Setpoint (% of nom.). The background color of
this field is green when the BE2000E is operating in AVR mode and is regulating the var setpoint.
Setpoint - Power Factor. This setting determines the level of power factor regulation maintained by the
BE2000E. The power factor setpoint can also be entered at the Setting Adjustments screen, Setpoint tab,
Power Factor Control (PF) - PF Setpoint. Power Factor setpoint values are adjustable from
–0.6 to –1 (1)
or 0.6 to +1 in 0.001 increments. The background color of this field is green when the BE2000E is
operating in AVR mode and is regulating the power factor setpoint.
Control Mode. Clicking the AVR button changes the color of the adjacent AVR indicator to green and
enables the AVR operating mode. When operating in AVR mode, the BE2000E regulates the generator
output voltage at the AVR setpoint. Clicking the FCR button changes the color of the adjacent FCR
indicator to green and enables the FCR operating mode. When operating in FCR mode, the BE2000E
maintains the field current at the FCR setpoint.
Fine Adjustment. Raise and Lower buttons control the fine adjustment of the operating setpoint. (The fine
adjustment through the front panel push buttons only controls the voltage setpoint.) Raise and Lower
buttons perform the same function as closing the appropriate set of contacts connected to the External
Adjust terminals (6D and 7 to decrease, 6U and 7 to increase) of the BE2000E. In AVR mode, each click
of the Raise button increases the voltage setpoint 0.01 volts; each click of the Lower button decreases
the voltage setpoint 0.01 volts. The minimum and maximum limits for fine adjustment of the voltage
setpoint are controlled by the Regulator Sensing Voltage setting (System Configuration screen) and the
Fine Voltage Adjustment - Band setting (Setting Adjustments screen). Fine adjustment of the voltage
setpoint can be increased/decreased no higher/lower than the Regulator Sensing Voltage setting
plus/minus the Band setting. For example, a Regulator Sensing Voltage setting of 100 volts and a Band
setting of 10 percent allows the Fine Adjustment function to increase the voltage setpoint to a maximum
of 110 volts and decrease the voltage setpoint to a minimum of 90 volts. For VAR, PF or FCR modes, the
Raise and Lower buttons allow fine adjustment over the entire adjustment range.
