Introduction
The BE1-11m Motor Protection System provides flexible, reliable, and economical protection, control,
monitoring, and measurement functions for medium and large motors. The BE1-11m offers 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 BE1-11m offers
motor maintenance data, learns and records start data, breaker- and trip-circuit monitoring, oscillography,
and sequential events recording. Control features include manu al and emer genc y s tar ting, ther mal
capacity start inhibiting, start and stop buttons, virtual selector switches, virtual lockout, and variablemode timers. System metering and status infor mat ion are available at the BE1-11m front panel and
through the BE1-11m communication ports. The capabilities of the BE1-11m make it appropriate for use in
medium and large motor applications and in critical small motor applications. BE1-11m applications
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 BE1-11m and configuring a
protection and control scheme for your application. Through BESTCOMSPlus, all BE1-11m settings and
logic can be retained in a file for printing or uploading to other BE1-11m protection 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, BE1-11m settings, and BE1-11m status. Pushbuttons enable navigation through the display
menu, changes to settings, and resetting of targets (with password access).
Applications
The capabilities of the BE1-11m make it ideally suited for applications with the following attributes:
• Applications with large motor or important process that require comprehensive motor protection
and control
• Applications that require loss of excitation protection for synchronous motors
• Applications requiring an interface between the protection and control package and the process
control systems
• Isolation between the RTDs and the BE1-11m due to distance between the BE1-11m package

BE1-11m Introduction
2 9424200996 Rev L
Features
The BE1-11m protection 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 BE ST logic™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 BE1-11m has a front-panel display and 12 LED indicators: Power Supply Status, Relay Trouble
Alarm, Minor Alarm, Major Alarm, Trip, Stopped, Starting, Running, RTD Alarm, Overload, Start Blocked,
and Lockout. 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 a nd 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 BE1-11m reporting the
information. Examples of BE1-11m identification field uses include motor name and motor number.
Device Security
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.
Security settings affect read and write access. Refer to the Security chapter for more information.
Setting Groups
Four setting groups allow adaptive relaying to be implemented to optimize BE1-11m settings 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. BE1-11m timekeeping can be selfmanaged 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
Introduction BE1-11m
9424200996 Rev L 3
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.
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 . BE ST CO M SPlus
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 BE1-11m functions. 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 also 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 av ai lable for the Ether net port. Sep ar ate instruction manuals cover
each available protocol. Consult the produc t bullet in 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 fau lt prote c tion.
Each current sensing circuit has low burden and is isolated. Neutral, positive-sequence, and negativesequence current magnitudes are derived from the three-phase curr ents . An ind e pend ent 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 BE1-11m depending 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
Seven programmable contact sensing inputs with programmable signal conditioning provide a binary logic
interface to the protection and control system. 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
Eight programmab le gen er al-purpose contact outputs provide a binary logic interface to the protection
and control system. 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
BE1-11m Introduction
4 9424200996 Rev L
each output and to each state (energized and de-energized) 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, 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. Seven frontpanel LEDs provide status for Stopped, Starting, Running, RTD Alarm, Overload, Start Blocked, and
Lockout. Motor status is fully programmable with BESTlogicPlus.
Alarms
Extensive self diagnostics will trigger a fatal relay trouble alarm if any of the BE1-11m core 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 userdefinable logic conditions u sing BE STlogicPlus.
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 BE1-11m offers 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 BE1-11m provides extensive general status reporting for monitoring, commissioning, and
troubleshooting. Status reports are available from the front-panel display or communication ports.
Introduction BE1-11m
9424200996 Rev L 5
Note
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
BE1-11m records and reports oscillography data in industry-standard IEEE, COMTRADE format to allow
using any fault analysis software. Basler Electric provides a Windows
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 BE1-11m inputs 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.
® based program called
Protection and Control
Protection functions consist of Undervoltage, Overvoltage, Frequency, Instantaneous Undercurrent,
Instantaneous Overcurrent, Breaker Failure, Inverse Overcurrent, Phase Current Differe nti al, Power, Loss
of Excitation, Thermal, Incomplete Sequenc e, and Ana log protection. Virtual Control Switches, Timers, a
Lockout Function, and a Breaker Control Switch make up the control functions. 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 for one of three, two of three, or three of three logic.
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. Refer to the T ime Cur ve
Characteristics chapter.
Auxiliary Overvoltage (59X) Protection
Two auxiliary overvoltage elements provide overvoltage protection. Auxiliary overvoltage protection
elements can be set to individually monitor the third harmonic, neutral-shift, positive-sequence, negativesequence, 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. Inverse or definite time can be
selected. Refer to the Time Curve Characteristics chapter.
Frequency (81) Protection
Four independent frequency elements can be set for over, under, or rate of change (81R) frequency
operation. Each can be individually set 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”.
BE1-11m protection 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.
BE1-11m Introduction
6 9424200996 Rev L
Note
Breaker Failure (50BF) Protection
One breaker failure function provides protection and security for the power system against failure of the
monitored breaker.
Inverse Overcurrent (51) Protection
Five inverse overcurrent elements can be set for single-phas e, thr ee-phase, ground, neutral, positivesequence, 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, a
fixed time curve, and a user programmable curve. Refer to the Time Curve Characteristics chapter for
more information about the inverse over cur r ent protec t i on characteristic curves.
Negative-sequence current protection (46) is included as a mode of the 51 (inverse overcurrent) element.
Each inverse overcurrent element can be individually set for forward, reverse, or non-directional control.
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.
Phase Current Differential (87) Protection
One phase current differential element provides three-phase, percent age-restrained, differential
protection with dual-s lo pe, i n-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 adap ted as appropr i ate for any poss ible thr ee-phase or single-phase voltage
transformer connection. Directional power is calibrated on a three-phase basis regardless of the voltage
transformer connection used. Directional Power Protection can be set for one of three, two of three, three
of three, or total power.
BE1-11m 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.
Introduction BE1-11m
9424200996 Rev L 7
Resistance Temperature Detector (49RTD)
Fourteen resistance temperature detector elements provide over/undertemperature protection in
applications where a remote RTD module is connected to the BE1-11m via 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 num ber 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. For more information, refer to the RTD Module chapter.
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 mis-operations of the 27P, 47, 59P, 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 BE1-11m protection 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. Progr a mm i ng with BEST logicPlus 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.
BE1-11m Introduction

Programming the BE1-11m
This section contains an introduction to BESTCOMSPlus, explains summary screens, and gives an
example of settings elements and programming logic.
Introduction to BESTCOMSPlus®
BESTCOMSPlus is a Windows®-based, PC application that provides a user-friendly, graphical user
interface (GUI) for use with Basler Electric communicating products. The name BESTCOMSPlus is an
acronym that stands for Basler Electric Software Tool for Communications, Operations, Maintenance, and
Settings.
BESTCOMSPlus provides the user with a point-and-click means to set and monitor the BE1-11m. The
capabilities of BESTCOMSPlus make the configuration of one or several BE1-11m Motor Protection
Systems fast and efficient. A primary advantage of BESTCOMSPlus is that a settings scheme can be
created, saved as a file, and then uploaded to the BE1-11m at the user’s conv e nie nc e.
The BE1-11 plugin opens inside the B ESTCO M S Plus main shell. The same default logic scheme that is
shipped with the BE1-11m is brought into BESTCOMSPlus by downloading settings and logic from the
BE1-11m or by selecting application type “M” on the Style Number screen. This gives the user the option
of developing a custom setting file by modifying the default logic scheme or by building a unique scheme
from scratch.
BE1-11m Quick Start
14 9424200996 Rev L
BESTlogic™Plus Programmable Logic is used to program BE1-11m logic for protection elements, inputs,
outputs, alarms, etc. This is accomplished by the drag-and-drop method. The user can drag elements,
components, inputs, and outputs onto the program grid and make connections between them to create
the desired logic scheme.
BESTCOMSPlus also allows for downloading industry-standard COMTRADE files for analysis of stored
oscillography data. Detailed analysis of the os c illogr a phy files can be acc ompl ish ed usi ng BEST wave
software.
Figure 8 illustrates the typical user interface components of the BE1-11 plugin with BESTCOMSPlus.

nominal quantities are set to 69.3 volts and 3.6 amps. Motor parameters are set to 4.5 Full Load Amps
and 1.15 Service Factor. The 50-4 element is set for a 5.62 amp pickup and a 30 second time delay.
Additionally, the element pickup output is logically wired to output 4 and a user alarm.
Step 1: Star t BE ST C OMSPlus and select New Connection, BE1-11 from the Communication pull-down
menu to connect to the BE1-11m. See Figure 6.
Step 2: The BE1-11 Connection screen appears. See Figure 7. Select USB Connection and click
Connect.
Step 3: Select Download Settings and Logic from Device from the Communication pull-down menu. This
copies all settings and logic from the BE1-11m to BESTCOMSPlus.
Step 4: Click on the View drop-down button and de-select Show Metering Panel and Show Setting
Information. See Figure 9. This maximizes the workspace.
Step 5: In the Settings Explorer, click the “+” next to BE1-11. This expands the sub menus in the tree.
Now expand System Parameters and select the Motor Configuration screen. See Figure 11.
Step 6: Under Nominal Settings, enter settings for Secondary Phase Voltage (69.3 V) and Secondary
Phase Current (3.6 A). Under Motor Configuration, enter settings for Full Load Amps (4.5 A) and
Service Factor (1.15).

Step 7: In the Settings Explorer, expand Protection, Current and select the Instantaneous Overcurrent
(50-4) screen. See Figure 12.
Step 8: Select the Mode (3 Phase) and enter settings for Pickup (5.62 A) and Time Delay (30,000 ms).
Step 9: In the Settings Explorer, click BESTlogicPlus Programmable Logic to open the logic diagram.
Click the Logic Page 3 tab. See Figure 13. Examine the 50-4 element. Off-Page Inputs and an
AND gate are used to block operation of the 50-4 element when the motor is starting or stopped.
In other words, the 50-4 element is only protecting the motor when it is running.
Off-Page Inputs/Outputs are used to make connections between logic pages and help keep logic
diagrams free from clutter. The Trip output is connected to an Off-Page Output named Overload.
This Overload Off-Page Output is carried over to Logic Page 4 (Figure 14) where it becomes an
Off-Page Input. The Overload Off-Page Input and several others are AND gated to physical
Output 1 on the BE1-11m. Therefore, the OUT1 contacts operate when the 50-4 element is
tripped.
