General Information
The BE2000E is an electronic, solid-state, microprocessor-based control device. The BE2000E regulates
the output voltage of a brushless, ac generator by controlling the current into the generator exciter field.
Input power to the BE2000E is from a multi-pole, high-frequency, permanent magnet generator (PMG).
The BE2000E is supplied in an encapsulated package designed for behind-the-panel mounting. The
BE2000E is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators
(LEDs) annunciate regulator status and system conditions. BE2000E connections are made through
quarter-inch, quick-connect terminals on the rear panel. A nine-pin DB-9 type connector on the rear panel
provides communication between the BE2000E and an IBM compatible PC.
Features
BE2000E units have the following features and capabilities:
•Four control modes: automatic voltage regulation (AVR), manual or field current regulation (FCR),
power factor (PF) regulation, and reactive power (var) regulation.
• Programmable stability settings.
• Soft start control with an adjustable time setting in AVR control mode.
• Overexcitation (OEL) limiting in AVR, var, and PF control modes.
• Underfrequency (volts/hertz) regulation.
• Crowbar circuitry protects the field.
• Overtemperature protection.
• Three-phase or single-phase generator voltage (RMS) s ens ing/re gu lat ion in A VR mode .
• Single-phase generator current sensing for metering and regulation purposes.
• Field current and field voltage sensing.
• Four contact sensing inputs for system interface.
• One common output relay for alarm indication and trip functions.
• Six protection functions (overexcitation shutdown, generator overvoltage shutdown, BE2000E
overtemperature shutdown, loss of generator sensing shutdown, overexcitation limiting and
crowbar shutdown).
• Generator paralleling with reactive droop compensation and reactive differential compensation.
• Front-panel human-machine interface (HMI) indicates system and BE2000E status and gives the
ability to make setting changes at the front panel.
•Rear RS-232 communication port for personal computer communication using BESTCOMS™-
BE2000E Windows® based software for fast, user-friendly, setup and control.

Human-Machine Interface
The BE2000E Human-Machine Interface (HMI) consists of front panel controls and indicators and a rear
panel communication port.
Front Panel Controls and Indicators
BE2000E front panel controls and indicators consist of 12 red LEDs and three pushbuttons. Figure 1
illustrates the front panel controls and indicators of the BE2000E. The LEDs indicate control mode and
status conditions and are also used when adjusting settings at the front panel.

Read and understand the operation of the individual adjustments
before attempting any initial adjustments.
Initial Adjustments
Before starting the generator, the procedures in the following paragraphs should be performed.
Remove the 5-ampere fuse before starting the generator for the first time. Perform all preliminary engine
governor adjustments without the regulator energized.
After initial governor adjustments are complete, reinstall the 5-ampere fuse, and connect only the power
input leads or PMG leads to the regulator. Remove all other regulator connections that may be present
and temporarily insulate them.
Start and run the generator at rated speed. The regulator will perform the self-test and enter a shutdow n
mode. At this time, initial adjustments can be made. To do this, step through each adjustment using the
“SELECT” button. For each adjustment, press the “UP” or “DOWN” button to obtain the desired level on
the LED bar graph.
After the initial adjustments are made, shut down the generator and connect the remaining regulator
leads. The generator may be started and final adjustments may be performed on the regulator.

Making Settings Changes
The following paragraphs describe how the HMI is used to make setting changes.
Front Panel Operation
The LEDs indicate control mode and status conditions and are also used when adjusting settings at the
front panel. Repeatedly pressing the “SELECT” button steps through the various adjustments, starting
with the “Coarse Voltage” adjustm ent and progres s ing thr oug h to the “Fine Voltage” adjustment. The next
press of the “SELECT” button exits the adjustment mode.
When in the adjustment mode, only the adjustment LEDs will be lit. All mode status LEDs will be turned
off. Adjustment LEDs are of two types. The first type is the LED that indicates the function being adjusted.
This LED blinks slowly (approximately once per second). The second type is the LED that indicates the
level of adjustment. This LED is on steady. The level of adjustment is changed by pressing the “UP” or
“DOWN” button. When an adjustment level LED (on steady) overlaps the function LED (slow blinking), the
LED will remain in the slow blinking mode. If no button is pressed for a period of one minute, the regulator
saves the settings and exits the adjustment mode. If regulator power is interrupted before the automatic
save feature is commanded, that level of adjustment will be lost.
When the regulator is not in the adjustment mode and either the “UP” or “DOWN” button is pressed, the
regulator enters the “Fine Voltage” adjustment mode and changes the generator fine voltage set point by
0.1V. Successive presses of the “UP” or “DOWN” button shall continue to adjust the fine voltage setting.
Pressing the “SELECT” button causes the regulator to exit the adjustment mode. Mode status LEDs blink
approximately twice per second.

Functional Description
This chapter describes how the BE2000E functions and explains its operating features. To ease
understanding, BE2000E functions are illustrated in the block diagram of Figure 3. A detailed description
of each function block is provided in the paragraphs under the heading of BE2000E Function Blocks.
BE2000E operating features include four operating modes, four protective functions, startup provisions,
reactive droop compensation, underfrequency compensation, and an auxiliary analog input. A detailed
description of each operating feature is provided in the paragraphs under the heading of BE2000E Operating Features.
Figure 3. Simplified Block Diagram
BE2000E Function Blocks
The following paragraphs describe each of the function blocks illustrated in Figure 3. The function of each
block is explained along with the operation of all function block inputs and outputs.
Analog Inputs
Six analog voltage and current inputs may be sensed and brought to the BE2000E input.
Generator Voltage
Generator voltage is monitored at terminals E1 (A-phase), E2 (B-phase), and E3 (C-phase). Nominal
voltages of up to 600Vac may be sensed at these terminals. Voltage applied to these inputs is scaled and
conditioned before being applied to the input of the ADC. The voltage signal from phase C and A (V
the generator is used by the ADC to calculate the rms value of generator voltage across phases C and A.

) of
14 9287500995 Rev B
Caution
Likewise, the voltage signal from phase C and B (V
) of the generator is used by the ADC to calculate
C-B
the rms value of generator voltage across phases C and B. The rms value of generator phase B to phase
A voltage (V
phase C to phase B (V
) is calculated by the microprocessor from the phase C to phase A signal (V
B-A
) signal.
C-B
Additionally, the generator phas e C to phase A (V
) signal is applied to a filtered zero cross detector
C-A
) and the
C-A
circuit. This signal is applied to the microprocessor and is used to calculate generator frequency.
Phase B Line Current
The phase B line current (IB) signal is developed through a customer supplied current transformer (CT)
and monitored through terminals CT1 and CT2. Current up to 5 amperes rms may be monitored at these
terminals. The current monitored at these terminals is scaled and conditioned by an internal current
transformer and active circuitry for use by the ADC. The signal applied to the ADC is used to calculate the
rms value of phase B line current.
Additionally, the phase angle between phase B line current and phase C to phase A generator voltage is
calculated for use during Droop and Var/ Pow er Fact or oper at ion .
Field Voltage (
VFIELD
)
Voltage across the regulator field output terminals, F+ and F–, is monitored, scaled, and conditioned
before being applied to the ADC. This signal is used to calculate the dc value of field voltage for use in
system protection.
Field Current (I
FIELD
)
Current through the main power output switch is converted to a proportional voltage level. This voltage
signal is scaled and conditioned before being applied to the input of the ADC. The result is used to
calculate the dc value of field current for use in the Manual mode of operation as well as protection of the
system.
Analog (Auxiliary) Input
If the dc voltage is removed from the Analog (Auxiliary) Input, the
operating setpoint will return to the original value.
This input allows adjustment of the BE2000E regulation setpoint by the application of a positive or
negative dc voltage across terminals A and B. Voltage up to +3 Vdc may be applied at this input. The
circuit induces a 1,000-ohm burden on the dc source. The application of a +3 Vdc signal corresponds to a
+30 percent change in setpoint.
Contact Input Circuits
Four contact input circuits powered from an internal 13 Vdc supply provide input control from usersupplied contacts.
Raise
Closing a contact across terminals 6U and 7 causes the active operating setpoint to increase. This
function is active as long as the contact is closed.
Lower
Closing a contact across terminals 6D and 7 causes the active operating setpoint to decrease. This
function is active as long as the contact is closed.
Functional Description BE2000E
9287500995 Rev B 15
Var/Power Factor Control (52J/K)
Closing a contact across terminals 52J and 52K disables var/power factor control. An open contact
enables the BE2000E to control the generator reactive power in either the var or the power factor mode.
For more information, refer to the Parallel Generator Compensation (52L/M) contact input.
Parallel Generator Compensation (52L/M)
Closing a contact across terminals 52L and 52M disables parallel operation. An open contact enables
parallel operation and the BE2000E operates in reactive droop compensation mode.
The 52J/K input has priority. Therefore, if the 52J/K and the 52L/M inputs are both open, the system
operates in var/power factor mode.

The communication port provides the interface for user programming (setup) of the BE2000E. Connection
is made to the female RS-232 (DB-9) connector with a user-supplied, standard 9-pin cable. The
communication port is optically isolated and is powered from a transformer-isolated supply.
Microprocessor
The microprocessor is the heart of the BE2000E and performs measurement, computation, control, and
communication functions by the use of its embedded programming and the nonvolatile settings stored in
its memory.
Power Input Stage
Input power is applied to terminals 3 and 4 from the PMG. It is rectified and filtered before being applied
to the power amplifier and the power supply. Input power is single-phase in the range of 180 to 240 Vac
at a frequency of 200 to 360 hertz.
Power Supply
The internal switch-mode power supply receives power from the power input stage and supplies power at
the required dc voltage levels to the internal circuitry of the BE2000E.
Power Amplifier Stage
The power amplifier receives power from the power input stage and supplies a controlled amount of
power to the exciter field via terminals F+ and F–. The amount of power supplied to the exciter field is
based on gating pulses received from the microprocessor. The power amplifier uses a solid state power
switch to provide the required power to the exciter field. Power amplifier output to the field is rated up to
75 Vdc at 3 Adc continuous and 150 Vdc at 7.5 Adc for 10 seconds.
Front Panel Indicators
Twelve front panel LED indicators light to indicate various operating modes, protective functions, and
adjustments. The Human-Machine Interface chapter provides more information about the front panel
indicators.
Front Panel Switches
Changes to settings can be made at the front panel using the three pushbutton switches. These pushbuttons are labeled Select, Up, and Down. The Human-Mac hin e Inter face ch apter prov ides more information about the front panel switches.
Relay Output
A common alarm output contact is provided through terminals AL1 and AL2. This normally open, form A
contact annunciates alarm or generator trip conditions and closes in the event of a protective shutdown or
transfer. The relay output is non-latching.

BE2000E Operating Features
The following paragraphs describe the characteristics of each BE2000E operating feature.
Operating Modes
The BE2000E provides up to four modes of operation selectable through Windows® communication
software. Automatic voltage regulation mode, Manual mode, Var mode, and Power Factor mode are
standard features.
Automatic Voltage Regulation Mode
In Automatic Voltage Regulation (AVR) mode, the BE2000E regulates rms generator output voltage. This
is accomplished by sensing generator output voltage and adjusting dc output excitation current to
maintain voltage at the regulation setpoint. The regulation setpoint is adjusted by the R aise and Low er
contact inputs, front panel switches, or through Windows communication software. The regulation point
may also be modified by the Droop function or the Underfrequency function under certain conditions.
Manual Mode
In Manual mode, also known as Field Current Regulation (FCR) mode, the BE2000E maintains dc
excitation current at a set level. The current-level setpoint is adjustable from 0 to 3 Adc by the Raise and
Lower contact inputs, front panel switches, or through Windows communication software.
The Manual mode excitation level must be evaluated prior to enabling
this feature. If the level of excitation current is inappropriate for the
generator, severe damage to the generator may occur.
Var Control Mode
In Var Control mode, the BE2000E maintains generator vars (volt-amperes, reactive) at a set level when
paralleling with an infinite bus. The BE2000E calculates generator vars using the sensed generator output
voltage and current quantities and then adjusts the dc excitation current to maintain vars at the setpoint.
Var control is enabled and disabled through the front panel switches or Windows communication
software. When the software is turned on, var control is enabled or disabled through the var/Power Factor
Control (52J/K) contact input circuit. The var setpoint is adjustable from 100 percent absorb to 100
percent generate through the Raise and Lower contact inputs, front panel switches, or through Windows
software.
Power Factor Control Mode
In Power Factor Control mode, the BE2000E maintains generator power factor at a set level when
paralleling with an infinite bus. The BE2000E calculates generator power factor using the sensed
generator output voltage and current quantities and then adjusts the dc excitation current to maintain
power factor at the setpoint. Power factor control is enabled or disabled through the front panel switches
or Windows software. When the software is turned on, it is enabled or disabled through the var/Power
Factor Control (52J/K) contact input circuit. The power factor setpoint is adjustable between 0.6 lag and
0.6 lead through the Raise and Lower contact inputs, front panel switches or through Windows
communication software.
Reactive Droop Compensation
The BE2000E provides a reactive droop compensation feature to assist in the sharing of reactive load
during parallel generator operation. When this feature is enabled, the BE2000E calculates the reactive
portion of the generator load using the sensed generator output voltage and current quantities and then
modifies the voltage regulation setpoint accordingly. A unity power factor generator load results in almost
no change in generator output voltage. A lagging power factor generator load (inductive) results in a
Functional Description BE2000E
9287500995 Rev B 17
reduction of generator output voltage. A leading power factor generator load (capacitive) results in an
increase of generator output voltage. Droop is adjustable up to 10 percent with rated, nominal B-phase
line current (5 amperes applied through terminals CT1 and CT2) and 0.8 power factor. The droop feature
is enabled and disabled through the Parallel Generator Compensation contact input circuit (terminals 52L
and 52M). The 52J/K input must also be closed to disable droop.
Underfrequency
Generator Underfrequenc y
When generator frequency drops below the selected knee frequency setpoint, the voltage setpoint is
automatically adjusted by the BE2000E so that generator voltage follows the selected PU (per unit) V/Hz
curve. When operating on the selected PU V/Hz curve, the Underfrequency Active indicator flashes on
the front panel and in BESTCOMS™-BE2000E software. The knee frequency is adjustable from 40 to 65
hertz and the PU V/Hz curve may be set to a slope from 1 to 3 in increments of 0.01 through the Windows
communication software. The default is 59 Hz and a slope of 1.
Engine Unloading
The engine unloading feature modifies the underfrequency curve. This feature becomes active when the
generator frequency decreases a programmable amount (Unloading Activation - Frequency) below the
knee frequency setpoint, and when the speed change rate is greater than the Unloading Activation - Rate.
The amount of droop while engine unloading is active is adjusted by the Unloading Droop - Percentage
(%) setting. The amount of time engine unloading is active is set by Unloading Droop - Time (sec.).
Engine unloading adjustments are made through BESTCOMS-BE2000E software.
Unloading Activation - Frequency (Hz) is entered as a value below the underfrequency corner where the
engine unloading feature may be activated. A frequency value of 0.9 to 9.0 Hz can be entered in 0.1 Hz
increments. The default value is 0.9 Hz.
Unloading Activation - Rate (Hz/25 ms) of 0 to 25.5 Hz per 25 ms can be entered in 0.1 Hz per 25 ms
increments. The engine unloading feature is activated when the frequency rate of change exceeds the
setting of this field. The default value is 0.1.
Unloading Droop - Percentage (%) field defines the percent drop in generator output voltage for each 1.5
percent decrease in generator frequency when operating in the Engine Unloading mode. The Unloading
Droop Percentage is adjustable from 1 to 20 percent in 1 percent steps. The default value is 10 percent.
Unloading Droop - Time (sec) value defines the length of time that the Engine Unloading mode may be
active before control is passed to the normal Underfrequency mode of operation. Droop time is adjustable
from 1 to 5 seconds in 1 second increments. The default value is 1 second.
Protection
The BE2000E has the six protective functions listed below:
• Overexcitation shutdown
• Generator overvoltage shutdown
• BE2000E overtemperatur e s hutdow n
• Loss of generator sensing shutdown
• Overexcitation limiting
• Crowbar shutdown
Each function, except Crowbar Shutdown, has a corresponding front panel indicator that lights when the
function is active. An active function (except Crowbar Shutdown) is also annunciated through the
Windows communication software.
Overexcitation Shutdown (Field Voltage)
This function is enabled or disabled through BESTCOMS-BE2000E software. When enabled, if field
voltage exceeds the setpoint (80 Vdc default), the Overexcitation Shutdown indicator flashes on the front
panel and in the Windows communication software, the relay output closes after 15 seconds and the
BE2000E Functional Description
18 9287500995 Rev B
BE2000E shuts down. When the BE2000E is powered up following an over-excitation shutdown, the
Overexcitation Shutdown indicator will flash for 5 seconds.
Generator Overvoltage Shutdown
The BE2000E monitors the sensed generator output voltage. If it exceeds the overvoltage setpoint (a
percent of nominal) for 0.75 seconds, the Generator Overvoltage indicator flashes on the front panel LED
and in the Windows communication software, the relay output closes and the BE2000E shuts down.
When the BE2000E is powered up following a generator overvoltage shutdown, the Generator
Overvoltage indicator will flash for 5 seconds. The default setpoint is 120 percent of nominal.
BE2000E Overtemperature Shutdown
A temperature sensor within the BE2000E continually monitors the temperature of the device. If the
temperature exceeds 70° C (158° F), the BE2000E Over temp er ature indic at or flas hes on the front pan el
and in the Windows communication software, the relay output closes and the BE2000E shuts down.
Loss of Generator Sensing Shutdown
The BE2000E monitors the sensed generator output voltage and takes protective action if a loss of
sensing voltage is detected. For single-phase sensing, a sensed voltage of less than 50 percent of
nominal is interpreted as a loss of sensing. For three-phase sensing, the total loss of a sensed phase or
an imbalance between phases of more than 20 percent nominal is interpreted as a loss of sensing. When
sensing input continuity is not lost, an adjustable time delay of 0 to 25 seconds is present when a loss of
sensing condition is detected. If sensing input continuity is lost, the time delay is disabled.
If a loss of sensing occurs, the Loss of Generator Sensing indicator flashes on the front panel and in the
Windows communication software, the relay output closes, and the BE2000E shuts down. When the
BE2000E is powered up following a loss of generator sensing shutdown, the Loss of Sensing indication
will flash for 5 seconds.
This function is disabled when a generator short circuit condition is detected or when sensed frequency
drops below 12 Hz. A generator short-circuit is determined when the phase B CT current exceeds 3PU
(>15 Aac sensing current). Loss of sensing is not active during soft start time.
Overexcitation Limiting (Field Current)
The BE2000E has a field current limit that is factory preset at 6.5 amperes. The limit is adjustable from 0
to 7.5 amperes with an adjustable time delay that has a range of 0 to 10 seconds. Both settings are made
through the Windows communication software. When the overexcitation limit is exceeded, the
Overexcitation Limiting indicator flashes on the front panel and in the Windows communication software.
When the adjustable time delay expires, the relay output closes and the BE2000E shuts down. When the
BE2000E is powered up following overexcitation limiting, the Overexcitation Limiting indicator will flash for
5 seconds.
Crowbar Shutdown
The Crowbar Shutdown Circuit protects the generator rotor from overcurrent damage resulting from a
shorted BE2000E power switch. During operation, if the field voltage exceeds the setpoint and the power
stage receives no gating pulses for 1.5 seconds, the Crowbar Circuit activates and places a short-circuit
across the BE2000E input power terminals. This protects the generator by blowing the input power fuse
and removing operating power from the device.
Generator Soft Start
The BE2000E incorporates an adjustable soft start feature that controls the time for generator voltage to
ramp to the regulation setpoint. The ramp rate is adjustable from 1 to 120 seconds in 1 second
increments through the Windows communication software. The underfrequency feature is also active
during soft start and takes priority in control of the generator voltage. The default setting is 7 seconds.
Functional Description BE2000E
9287500995 Rev B 19
Installation
The BE2000E is delivered in a sturdy carton to prevent shipping damage. Upon receipt, check the part
number against the requisition and packaging list for agreement. Inspect for damage, and if there is

Note
Connections
BE2000E connections are dependent on the application. Incorrect wiring may damage the unit.
Be sure that the BE2000E is hard-wired to earth ground with no
smaller than 12 AWG copper wire attached to the ground terminal on
the rear of the unit case. When the unit is configured in a system with
other devices, it is recommended to use a separate lead to the ground
bus from each device.
BE2000E Terminations
BE2000E units have two types of interface terminals (Figure 6). One type is quarter-inch, quick-connect
terminals and the other is a nine-pin DB9 connector. All terminals are located on the rear of the unit. The
quarter-inch, quick-connect terminal labels are located on the rear of the case. Wires performing common
functions, such as voltage sensing leads, should be grouped together. The nine-pin DB-9 type connector
is used for temporary interface with both IBM compatible PCs and hand-held computers.
Figure 6 shows the terminal connections located on the rear panel of the BE2000E. Except as noted
above, connections should be made with minimum wire size of 14 AWG.

Phase B Line Current Sensing Input
Generator line current is stepped down through a user-supplied current transformer (CT). Secondary
current from that transformer is applied to terminals labeled CT1 and CT2.
Raise and Lower Contact Inputs
Remote setpoint adjustment may be accomplished by connecting a single-pole, double-throw (SPDT),
spring return, center-off switch to the terminals labeled 6U, 7, and 6D. To connect this switch, the center
pole, or common terminal, must be connected to terminal 7. The other two terminals are connected to
terminals 6U and 6D. This remote adjust switch may be mounted up to 150 feet (45 meters) away from
the BE2000E when using twisted, shielded cable.
Var/Power Factor Control Contact Input
A customer supplied enable/disable contact for this function connects to the terminals labeled 52J and
52K. This function is disabled by a closed contact.
Parallel Generator Compensation
A customer supplied enable/disable contact for this function connects to the terminals labeled 52L and
52M. This function is disabled by a closed contact.
Analog (Auxiliary) Adjust
If the dc voltage is removed from the Analog (Auxiliary) Input, the
operating setpoint will return to the original value.
This input allows adjustment of the BE2000E regulation setpoint by the application of a positive or
negative dc voltage across termi nals A and B. Voltage up to +3 Vdc may be applied at this input. The
circuit induces a 1,000-ohm burden on the dc source. The application of a +3 Vdc signal corresponds to a
+30 percent change in setpoint.
Power Supply Inputs
Power input terminals are labeled 3 and 4.
Chassis Ground
The chassis ground terminal is labeled GND.

BE2000E Connections for Typical Applications
Figures 9 through 12 illustrate typical applications using the BE2000E. Figure 9 shows an application
where the BE2000E is connected for three-phase voltage sensing. Figure 10 shows an application with
single-phase voltage sensing while Figure 11 illustrates an application with a single-phas e gen er ator.
Figure 12 illustrates the connection of two BE2000E devices used in a Cross-Current (Reactive
Differential) application. Note that the 0.1 ohm resistor shown may have to vary. When operating in
parallel reactive differential mode (cross current), attention must be paid to the use of the burden resistor
shown in Figure 12. The burden resistor should have a value approximately 10 times the cross current
loop resistance for proper differential operation. The value of 0.1 ohm is a suggested value. The voltampere (VA) capacity of the paralleling current transformers should be considered after sizing the burden
resistor.

Saving Settings to BE2000E Memory
Settings are saved in nonvolatile memory (EEPROM). In the event of a power loss, these are the settings
that are active at power up. If settings are changed and sent to the BE2000E but not sent to EEPROM,
the changed settings are lost if BE2000E operating power is lost. When exiting BESTCOMS-BE2000E or
closing communication, you are asked if you want to save the settings to EEPROM. This question is
asked even if no settings changes were made.

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 Setti ng Ad justme nts
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. Click ing 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.

Alarm/Status Tab
The Alarm/Status tab indicators provide the status of BE2000E protection functions, control modes, and
contact inputs. Alarm/Status tab indicators are illustrated in Figure 35 and are described in the following
paragraphs.
Figure 35. Metering, Operation and Alarms - Alarm/Status Tab
Protection Alarms. Protection Alarm indicators provide the status of BE2000E protection functions. Alarm
indicators include Overexcitation Shutdown, Overexcitation Limiting, Underfrequency, Generator
Overvoltage, Loss of Generator Sensing, and Unit Overtemperature. When a BE2000E protection
function detects an alarm condition, the appropriate indicator changes from black to red.
Control Status. The VAR/PF Mode Active indicator changes from black to red when the BE2000E is
operating in AVR mode and correction of power factor or vars is selected. The Low-Line Override Active
indicator changes from black to red when low-line override is active. The Single-Phase Override Active
indicator changes from black to red when single-phase override is active. The Low-Line and Single-Phase
Override Active indicator changes from black to red when both the low-line and single-phase override
functions are active. The Manual Mode Active indicator changes from black to red when the FCR control

Metering, the Metering Signal indicator stops flashing and the metering functions stop being updated.
PID Data
BESTCOMS-BE2000E enables generator stability to be set through the automatic calculation of PID
parameters. PID stands for Proportional, Integral, Derivative. The word proportional means that the
response of the BE2000E output is proportional or relative to the amount of change that is observed.
BESTCOMS™ Software BE2000E
9287500995 Rev B 53
Integral means that the BE2000E output is proportional to the amount of time that a change is observed.
Integral action eliminates offset. Derivative means that the BE2000E output is proportional to the required
rate of excitation change. Derivative action avoids excitation overshoot.
BESTCOMS-BE2000E automatically calculates PID values after the user selects the generator
frequency, generator time constant (T'do), and exciter time constant (Texc). With BESTCOMS-BE2000E
software, the user may generate new PID numbers, add to a PID list file, and update the AVR gain
settings.
The PID window (Figure 36) is accessed by clicking the PID button. The PID button can be clicked only
when the Stability Range setting of the Control Gain screen is set at a value of 21. (A setting of 21
enables the entry of custom stability settings through the PID window.) Then, when a field of the Control Gain screen is changed or selected, the PID button changes from gray to yellow and the button can be
clicked to view the PID window. After the PID number s are modified , calcu lat ed, and updated, the PID
window is closed by clicking the Update Setting Sc reen button. The modified PID values are then shown
on the Control Gain screen.
Figure 36. PID Window
PID Calculation Based on Input Values
The available range for the exciter time constant depends on the value entered for the generator time
constant. (The default value for the exciter time constant is the generator time constant divided by 6.) The
generator time constant value selected must be in the range of 1.00 to 15.00 seconds and in 0.05
increments. When the generator time constant value is 1.00, the available exciter time constant range is
0.03 to 0.50 in 0.01 second increments. When the generator time constant value is 15.00, the available
exciter time constant range is 0.30 to 3.00 in 0.01 second increments.
For example, when T'do is set at 2.0 seconds, Texc is 0.33. After specifying the input values, a set of PID
parameters (output data) is generated automatically. If T'do is set at 5.00 seconds, then Texc is 0.83
seconds. The calculated KP is 155.47, KI is 138.72, KD is 48, and Kg is 1.
PID parameters can be directly removed from, added to, or modified in the PID List Data. PID parameters
may also be saved into a file (pidlist.dat).

If connections are incorrect, correct the problem.
If connections are correct, proceed to Step 6.
Step 6. Verify that the load being applied to the generator for droop testing is not purely resistive.
If only a resistive load is being applied to the generator, apply an inductive load and retest.
If the load being applied to the generator is inductive, proceed to Step 7.
Step 7. Verify that your BE2000E is compatible with the current sensing transformer (5 A secondary)
being used. For example, a current sensing transformer with a 1 ampere output rating would
produce very little droop since your BE2000E has a 5 ampere current transformer input.
If the current transformer input is incorrect, replace the current sensing transformer for
compatibility.
If the current transformer input is correct, proceed to Step 8.
Step 8. If the above steps fail to correct the malfunction, replace the BE2000E unit.
