The BE1-11mMotor Protection System provides flexible, reliable, and economical protection, control,
monitoring, and measurement functions for medium and large motors. The BE1-11moffers thermal
protection of the motor with a current-based thermal model that includes unbalanced current biasing,
custom voltage dependent curves, RTD biasing, and emergency start override. The system offers
differential and overcurrent protection for internal faults as well as overcurrent, voltage, frequency, and
power elements for protection against abnormal system and process conditions. The BE1-11moffers
motor maintenance data, learns and records start data, breaker- and trip-circuit monitoring, oscillography,
and sequential events recording. Control features include manual and emergency starting, thermal
capacity start inhibiting, start and stop buttons, virtual selector switches, virtual lockout, and variable-
mode timers. System metering and status information are available at the BE1-11mfront panel and
through the BE1-11mcommunication ports. The capabilities of the BE1-11mmake it appropriate for use in
medium and large motor applications and in critical small motor applications. BE1-11mapplications
include utility power generation facilities, water treatment facilities, petroleum drilling and refining, pulp
and paper mills, and chemical plants.
A front-panel USB port or optional rear Ethernet port enables local communication between the BE1-11m
and a PC operating with BESTCOMSPlus®software. BESTCOMSPlus software simplifies the
commissioning process by providing a graphical interface for setting the BE1-11mand configuring a
protection and control scheme for your application. Through BESTCOMSPlus, all BE1-11msettings and
logic can be retained in a file for printing or uploading to other BE1-11mprotection systems. Oscillography
and sequential events records can be retrieved from a BE1-11m, viewed, and printed.
Front panel features include a large, backlit alphanumeric display and LED indicators that display system
parameters, BE1-11msettings, and BE1-11mstatus. Pushbuttons enable navigation through the display
menu, changes to settings, and resetting of targets (with password access).

Introduction BE1-11m
Features
The BE1-11mprotection system includes many features for the protection, monitoring, and control of
power system equipment. These features include protection and control functions, metering functions,
and reporting and alarm functions. A highly flexible programmable logic system called BESTlogic™Plus
allows the user to apply the available functions with complete flexibility and customize the system to meet
the requirements of the protected power system. Programmable I/O, extensive communication features,
and an advanced user interface provide easy access to the features provided.
The following information summarizes the capabilities of this multifunction device. Each feature, along
with along with its setup and use, is described in greater detail in the later chapters of this manual.
General Features
HMI (Human-Machine Interface)
Each BE1-11mhas a front-panel display and 12 LED indicators: Power Supply Status, Relay Trouble
Alarm, Minor Alarm, Major Alarm, Trip, Select Control Switch, Operate Control Switch, and Indicator 1
through 7 (programmable in BESTlogicPlus. The backlit, liquid crystal display (LCD) allows the BE1-11m
to replace local indication and control functions such as panel metering, alarm annunciation, and control
switches. Four scrolling pushbuttons enable navigation through the LCD menu tree. Parameters are
changed using the Edit pushbutton. Targets, alarms, and other registers are cleared with the Reset
pushbutton. In Edit mode, the scrolling pushbuttons provide data entry selections. Edit mode is indicated
by an LED on the Edit pushbutton. Start and Stop pushbuttons are programmable in BESTlogicPlus.
The LCD has automatic priority logic to govern which metering values are displayed on the screen so that
when an operator approaches, the metering data of most interest is automatically displayed without
having to navigate the menu structure. Scrollable metering parameters are selected on the General
Settings, Front Panel HMI settings screen in BESTCOMSPlus.
Device Information
The version of the embedded software (firmware), serial number, and style number are available from the
front-panel display or the communication ports.
Three free-form fields (Device ID, Station ID, and User ID) can be used to enter information to identify the
BE1-11m. These fields are used by many of the reporting functions to identify the BE1-11mreporting the
information. Examples of BE1-11midentification field uses include motor name and motor number.
Device Security
Security settings affect read and write access. Passwords provide access security for six distinct
functional access areas: Read, Control, Operator, Settings, Design, and Administrator. Each
username/password is assigned an access area with access to that area and each area below it. An
administrator password provides access to all six of the functional areas.
A second dimension of security is provided by the ability to restrict access for any of the access areas to
only specific communication ports. For example, you could set up security to deny access to control
commands through the Ethernet port.
Setting Groups
Four setting groups allow adaptive relaying to be implemented to optimize BE1-11msettings for various
operating conditions. Automatic and external logic can be employed to select the active setting group.
Clock
The clock is used by the logging functions to timestamp events. BE1-11mtimekeeping can be self-
managed by the internal clock or coordinated with an external source through a network or IRIG device.
A backup capacitor and additional battery backup are provided for the clock. During a loss of operating
power, the backup capacitor maintains timekeeping for up to 24 hours depending on conditions. As the
capacitor nears depletion, the backup battery takes over and maintains timekeeping. The backup battery
has a life expectancy of greater than five years depending on conditions.

9424200996 1-3
BE1-11mIntroduction
IRIG
A standard unmodulated IRIG-B input receives time synchronization signals from a master clock.
Automatic daylight saving time compensation can be enabled and set for floating or fixed dates.
NTP (Network Time Protocol)
NTP synchronizes the real-time clock to network time servers through the Ethernet port. BESTCOMSPlus
is used to establish the priority of time reference sources available to the BE1-11m, IRIG-B, NTP, DNP,
and RTC (real-time clock). The NTP address is set using BESTCOMSPlus.
Communications
Three independent communication ports provide access to all BE1-11mfunctions. A USB (universal serial
bus) port is located on the front panel, a two-wire RS-485 port is located on the rear panel, and an
optional Ethernet port is located on the rear panel. The RS-485 and Ethernet ports are electrically
isolated.
Modbus®and DNP3 protocols are optionally available for the RS-485 or Ethernet communication port.
The IEC 61850 protocol is optionally available for the Ethernet port when RS-485 option is N (None).
Separate instruction manuals cover each available protocol. Consult the product bulletin or Basler Electric
for availability of these options and instruction manuals. Modbus sessions can be operated
simultaneously over the Ethernet and RS-485 ports.
System Parameters
Three-phase currents and voltages are digitally sampled and the fundamental is extracted using a
Discrete Fourier Transform (DFT) algorithm.
The voltage sensing circuits can be configured for single-phase, three-phase-three-wire, or four-wire
voltage transformer circuits. Voltage sensing circuitry provides voltage protection, frequency protection,
polarizing, and watt/var metering. Neutral-shift, positive-sequence, and negative-sequence voltage
magnitudes are derived from the three-phase voltages. Digital sampling of the measured frequency
provides high accuracy at off-nominal values.
An auxiliary voltage sensing input (Vx) provides protection capabilities for over/undervoltage monitoring of
the fundamental and third harmonic voltage of the VT source connected to the Vx input. This capability is
useful for ground fault protection.
Each current sensing circuit has low burden and is isolated. Neutral, positive-sequence, and negative-
sequence current magnitudes are derived from the three-phase currents. An independent ground current
input is available for direct measurement of the current in a transformer neutral, tertiary winding or flux
balancing current transformer. Either one or two sets of CTs are provided in the BE1-11mdepending on
the style number. Refer to the style chart for more information.
Programmable Inputs and Outputs
Programmable inputs and outputs are described in the following paragraphs.
Programmable Inputs
Either seven or 10 programmable contact sensing inputs with programmable signal conditioning provide a
binary logic interface to the protection and control system. Refer to the style chart for I/O options. Each
input function and label is programmable using BESTlogicPlus. A user-meaningful label can be assigned
to each input and to each state (energized and de-energized) for use in reporting functions. Board
mounted jumpers support dual voltage ratings.
Programmable Outputs
Either eight or five programmable general-purpose contact outputs provide a binary logic interface to the
protection and control system. Refer to the style chart for I/O options. One programmable, failsafe contact
output serves as an alarm output. Each output function and label is programmable using BESTlogicPlus.
A user-meaningful name can be assigned to each output and to each state (energized and de-energized)

1-4 9424200996
Introduction BE1-11m
for use in reporting functions. Output logic can be overridden to open, close, or pulse each output contact
for testing or control purposes. All output contacts are trip rated.
Reporting and Alarms
Several reporting and alarm functions provide fault reporting, differential reporting, demand, breaker, and
trip circuit monitoring. Reporting of power quality, energy data, general status, and motor status is also
provided.
Motor Status
Motor status is available on the front-panel display and through the communication ports. Motor status is
fully programmable with BESTlogicPlus.
Alarms
Extensive self-diagnostics will trigger a fatal relay trouble alarm if any of the BE1-11mcore functions are
compromised. Fatal relay trouble alarms are not programmable and are dedicated to the Alarm output
(OUTA) and the front panel Relay Trouble LED. Additional relay trouble alarms and all other alarm
functions are programmable for major or minor priority. Programmed alarms are indicated by major or
minor alarm LEDs on the front panel. Major and minor alarm points can also be programmed to any
output contact including OUTA. Over 50 alarm conditions are available to be monitored including user-
definable logic conditions using BESTlogicPlus.
Active alarms can be read and reset at the front panel or through the communication ports. A historical
sequence of events report with time stamps lists when each alarm occurred and cleared. These reports
are available through the communication ports.
Breaker Monitoring
Breaker statistics are recorded for a single breaker. They include the number of operations, fault current
interruption duty, and breaker time to trip. Each of these conditions can be set to trigger an alarm.
Trip Circuit Monitor (52TCM)
The trip circuit of a breaker or lockout relay can be monitored for loss of voltage (fuse blown) or loss of
continuity (trip coil open). Additional trip or close circuit monitors can be implemented in BESTlogicPlus
using additional inputs, logic timers, and programmable logic alarms.
Demands
Demand values are continuously calculated for phase currents, neutral current, negative-sequence
current, ground current, real power, reactive power, and apparent power. The demand interval and
demand calculation method are independently settable for phase, neutral, and negative-sequence
measurements. Demand reporting records peak and present demand with time stamps for each register.
Power Quality
The BE1-11moffers IEC 61000-4-30 Class B power quality measurement performance. Power quality
settings include a fixed or sliding reference mode, dip hysteresis, dip ratio, swell hysteresis, and swell
ratio.
Energy Data Reporting
Energy information in the form of watthours and varhours is measured and reported by the BE1-11m.
Both positive and negative values are reported in three-phase, primary units.
General Status Reporting
The BE1-11mprovides extensive general status reporting for monitoring, commissioning, and
troubleshooting. Status reports are available from the front-panel display or communication ports.
Fault Reporting
Fault reports consist of simple target information, fault summary reports, and detailed oscillography
records to enable the user to retrieve information about disturbances in as much detail as is desired. The

BE1-11mIntroduction
BE1-11mrecords and reports oscillography data in industry-standard IEEE, COMTRADE format to allow
using any fault analysis software. Basler Electric provides a Windows®based program called
BESTwave™that can read and plot binary or ASCII format files that are in the COMTRADE format. A
copy of BESTwave is included on the BE1-11 product CD.
Sequence of Events Recorder
A Sequence of Events Recorder (SER) records and time stamps all BE1-11minputs and outputs as well
as all alarm conditions monitored by the BE1-11m. Time stamp resolution is to the nearest half-cycle. I/O
and Alarm reports can be extracted from the records as well as reports of events recorded during the time
span associated with a specific fault report.
Protection and Control
The BE1-11mincludes protection elements that monitor voltage, current, power, phase angle, frequency,
temperature, and more to provide protection against faults and abnormal operating conditions. Control
elements make the BE1-11mcapable of controlling complex distribution configurations. The following
paragraphs describe each protection and control function.
Undervoltage (27P) and Overvoltage (59P) Protection
Four phase undervoltage and two phase overvoltage elements are included. Phase
undervoltage/overvoltage protection can be set to operate when one, two, or three phases decrease
below the pickup level. When a four-wire voltage transformer connection is used, under/overvoltage
protection can be set for either phase-to-phase voltage or phase-to-neutral voltage. The 27P elements
are equipped with an undervoltage inhibit feature. Inverse or definite time can be selected.
Auxiliary Overvoltage (59X) Protection
Two auxiliary overvoltage elements provide overvoltage protection. Auxiliary overvoltage protection
elements can be set to monitor separately the third harmonic, neutral-shift, positive-sequence, negative-
sequence, or auxiliary fundamental voltages. Ground unbalance protection is provided when the auxiliary
voltage input is connected to a source of 3V0 such as a broken-delta VT or when 3V0 mode is selected to
obtain calculated offset voltage from the phase quantities. Inverse or definite time can be selected.
Frequency (81) Protection
Four independent frequency elements can be set for over, under, or rate of change (81R) frequency
operation. Each can be set separately to monitor the frequency on the main three-phase voltage input or
the Vx input. Rate of change can be set to operate on positive, negative, or “either”.
Note
BE1-11mprotection systems enabled for IEC-61850 communication
(style Mxxxx5xxxxxxxx) have their frequency protection elements fixed
at two underfrequency elements and two overfrequency elements.
Instantaneous Undercurrent (37) Protection
One instantaneous undercurrent element operates with three-phase current. This protective function will
trip the motor when a loss of load occurs.
Instantaneous Overcurrent (50) Protection
Six instantaneous overcurrent elements can be set for single-phase, three-phase, ground, neutral,
positive-sequence, negative-sequence, or unbalanced protection.
Breaker Failure (50BF) Protection
One breaker failure function provides protection and security for the power system against failure of the
monitored breaker.

Introduction BE1-11m
Inverse Overcurrent (51) Protection
Five inverse overcurrent elements can be set for single-phase, three-phase, ground, neutral, positive-
sequence, negative-sequence, or unbalanced protection. Inverse-overcurrent functions employ a dynamic
integrating timing algorithm covering a range from pickup to 40 times pickup with selectable
instantaneous or integrated reset characteristics. Inverse time overcurrent curves conform to IEEE Std
C37.112-1996 - IEEE Standard Inverse-Time Characteristic Equations for Overcurrent Relays, and
include seven curves similar to Westinghouse/ABB CO curves, five curves similar to GE IAC curves, four
table curves, a fixed time curve, and a user programmable curve.
Negative-sequence current protection (46) is included as a mode of the 51 (inverse overcurrent) element.
A separate ground current input provides ground overcurrent protection for a separate ground CT.
Optionally, an SEF (sensitive earth fault) version of the separate ground CT is available.
Note
BE1-11mprotection systems enabled for IEC-61850 communication
(style Mxxxx5xxxxxxxx) do not allow voltage controlled or restrained
overcurrent elements. Blocking a 51 with an Undervoltage (27)
element may allow control pending application requirements.
Phase Current Differential (87) Protection
One phase current differential element provides three-phase, percentage-restrained, differential
protection with dual-slope, in-phase, differential mode. In flux balance mode, the differential CTs are
connected in a flux balancing configuration.
Power (32) Protection
A directional power element can be set for forward or reverse, overpower or underpower protection. The
element can be used for any application requiring directional power flow detection including intertie
protection (interconnects between an electric utility and a source of non-utility generation). The power
measurement algorithm is adapted as appropriate for any possible three-phase or single-phase voltage
transformer connection. Directional Power Protection can be set for one of three, two of three, three of
three, or total power.
Note
BE1-11
m
protection systems enabled for IEC-61850 communication
(style Mxxxx5xxxxxxxx) have their power protection elements fixed at
one underpower element.
Loss of Excitation - Reverse Var Based (40Q) Protection
One loss of excitation element operates on excessive var flow into the machine, indicating abnormally low
field excitation.
Power Factor (55) Protection
A power factor element protects synchronous motors from receiving vars from the external power system
due to loss of field excitation.
Thermal Curve (49TC) Protection
A thermal curve element provides thermal protection of the motor with a current-based thermal model that
includes unbalanced current biasing, custom voltage-dependent curves, RTD biasing, and emergency
start override.

BE1-11mIntroduction
Resistance Temperature Detector (49RTD)
Fourteen resistance temperature detector elements provide over/undertemperature protection in
applications where a remote RTD module is connected to the BE1-11mvia Ethernet or RS-485 cable. For
more information, refer to the RTD Module chapter.
Incomplete Sequence (48) Protection
An incomplete sequence element protects the motor from damage by announcing an incomplete
sequence if the motor starts and does not reach the running state after the user-settable time delay
expires.
Starts per Time Interval (66) Protection
A starts per time interval element prevents the motor from starting if the user-defined number of starts is
exceeded within a user-defined time interval.
Restart Inhibit Protection
A restart inhibit element prevents the motor from being started when motor or system conditions are such
that a motor start would not be successful due to thermal limits, or motor starting is not desired for
process or system reasons.
Analog Input Protection
Eight analog input protection elements monitor external analog input signals when two remote RTD
modules are connected via an Ethernet or RS-485 cable. Four analog inputs are provided with each RTD
module.
Fuse Loss (60FL)
A fuse loss element protects against false tripping due to a loss of voltage sensing. Voltage transformer
circuit monitoring adds security by detecting problems in the voltage transformer sensing circuits and
preventing misoperations of the 27, 32, 55, 59, and 51/27 functions.
Breaker Control Switch (101)
Tripping and closing of a selected breaker can be controlled by the virtual breaker control switch. The
virtual breaker control switch is accessed locally at the front panel or remotely through the communication
ports.
Virtual Control Switches (43)
Five virtual control switches are accessed locally at the front panel or remotely through the
communication ports. Virtual switches can be used to trip and close additional switches or breakers, or
enable and disable certain functions.
Logic Timers (62)
Eight logic timers with six modes of operation emulate virtually any type of timer.
Lockout Functions (86)
Two lockout elements are provided.
BESTlogic™Plus Programmable Logic
Each BE1-11mprotection and control function is implemented in an independent function element. Every
function block is equivalent to its single function, discrete device counterpart so it is immediately familiar
to the protection engineer. Each independent function block has all of the inputs and outputs that the
discrete component counterpart may have. Programming with BESTlogicPlus is equivalent to choosing
the devices required by your protection and control scheme and then drawing schematic diagrams to
connect the inputs and outputs to obtain the desired operating logic.
Custom logic settings allow you to tailor the BE1-11mfunctionality to match the needs of your operation's
practices and power system requirements.
