Introduction
The BE1-11g Generator Protection System provides flexible, reliable, and economical protection, control,
monitoring, and measurement functions for small, medium, and large generators. The BE1-11g offers
vector jump, out of step, distance, phase and neutral current differential, overexcitation (V/Hz),
overcurrent, directional overcurrent, over/undervoltage, over/underfrequency, RTD (Resistance
Temperature Detector) with remote module, breaker failure, and fuse loss protection. It offers breakerand trip-circuit monitoring, and oscillography and sequential events recording. Control features include
virtual selector switches, circuit breaker control, virtual lockout, and variable-mode timer s. An auto
synchronizer is optional. System metering, status information, and fault locating are available at the
BE1-11g front panel and through the BE1-11g communication ports. The capabilities of the BE1-11g
make it suitable for detecting generator faults and abnormal operating conditions in an integrated system.
Suitable BE1-11g applications include large power generation, distributed generation, local backup
generation, and intertie protection applications.
A front-panel USB port or optional rear Ethernet port enables local communication between the BE1-11g
and a PC operating with BESTCOMSPlus® software. BESTCOMSPlus software simplifies the
commissioning process by providing a graphical interface for setting the BE1-11g and configuring a
protection and control scheme for your application. Through BESTCOMSPlus, all BE1-11g settings and
logic can be retained in a file for printing or uploading to other BE1-11g protection systems. Oscillography
and sequential events records can be retrieved from a BE1-11g, viewed, and printed.
Front-panel features include a large, backlit alphanumeric display and LED indicators that display system
parameters, BE1-11g settings, and BE1-11g status. Pushbuttons enable navigation through the display
menu, changes to settings, resetting of targets (with password access), and direct access to virtual
switches.
Applications
The capabilities of the BE1-11g make it ideally suited for applications with the following attributes:
• Generator specific protection and control elements including loss of field, out of step, stator
ground protection, and sync check or synchronizer
• Generator focused protection including reverse power, negative-sequence, overexcitation, and

Features
The BE1-11g 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 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 its setup and use, is described in greater detail in the later chapters of this manual.
General Features
HMI (Human-Machine Interface)
Each BE1-11g has a front-panel display and LED indicators. Protection systems in an H or P style case
have five LED indicators: Power Supply Status, Relay Trouble Alarm, Minor Alarm, Major Alarm, and Trip.
Protection systems in a J style case have 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 BE1-11g 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. Protection systems in a J-style case have pushbuttons for selecting and controlling the
virtual control switches.
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
BE1-11g. These fields are used by many of the reporting functions to identify the BE1-11g reporting the
information. Examples of BE1-11g identification field uses include station name, circuit number, relay
system, and purchase order, and others.
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 informat ion.
Setting Groups
Four setting groups allow adaptive relaying to be implemented to optimize BE1-11g settings for various
operating conditions. Auto matic and ex terna l log ic ca n be employ e d to select the active setting group.
Introduction BE1-11g
9424200994 Rev N 3
Clock
The clock is used by the logging functions to timestamp events. BE1-11g 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
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. BESTCOMSPlus
is used to establish the priority of time reference sources available to the BE1-11g, IRIG-B, NTP, DN P,
and RTC (real-time clock). The NTP address is set using BESTCOMSPlus.
Communications
Three independent communication ports provide access to all BE1-11g 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 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/underv olta ge mon itor ing of
the fundamental and third harmonic voltage of the VT source connected to the Vx input. This capability is
useful for ground fault protection or sync-check functions.
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 BE1-11g depending on
the style number. Refer to the style chart for more information.
Programmable Inputs and Outputs
Programmable contact inputs and outputs are described in the following paragraphs.
Programmable Inputs
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
BE1-11g Introduction
4 9424200994 Rev N
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.
Protection systems in a J style case are equipped with seven contact sensing inputs. Protection systems
in an H or P style case are equipped with five contact sensing inputs.
Programmable Outputs
Programmable general-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
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.
Protection systems in a J style case are equipped with eight general-purpose contact outputs. Protection
systems in an H or P style case are equipped with five general-purpose contact outputs.
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, and general status is also provided.
Alarms
Extensive self diagnostics will trigger a fatal relay trouble alarm if any of the BE1-11g 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 BE1-11g 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 BE1-11g. Both
positive and negative values are reported in three-phase, primary units.
Introduction BE1-11g
9424200994 Rev N 5
General Status Reporting
The BE1-11g provides 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
BE1-11g 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 BE1-11g inputs and outputs as well
as all alarm conditions monitored by the BE1-11g. 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 Overexcitation, Sync-Check, Undervoltage, Overvoltage, Vector Jump,
Frequency, Instantaneous Overcurrent, Breaker Failure, Inverse Overcurrent, Phase Current Differential
(optional), Neutral Current Differe nti al (optional), Power, Loss of Excitation, Distance, Out of Step,
Thermal, and Analog protection. Virtual Control Switches, Timers, a Lockout Function, a Breaker Control
Switch, and an Auto Synchronizer (optional) make up the control functions. The following paragraphs
describe each protection and control function.
Overexcitation (24) Protection
One volts per hertz protection element provides overexcitation protection for a generator and/or
transformer.
Sync-Check (25) Protection
With the auxiliary voltage input connected to the bus, one sync-check function provides synchronism
protection. Sync-check protection checks for phase angle difference, magnitude difference, frequency
difference (slip) and, optionally, if the three-phase VT frequency is greater than the auxiliary VT
frequency. One voltage monitor output (25VM) provides independent dead/live voltage closing logic.
Undervoltage (27P) and Overvoltage (59P) Protection
Five phase undervoltage and four 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 Undervoltage (27X) and Auxiliary Overvoltage (59X) Protection
Four auxiliary overvoltage and four auxiliary undervoltage elements provide over/undervoltage protection.
Auxiliary voltage protection elements can be set to individually monitor 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. The
27X is equipped with an undervoltage inhibit feature. Inverse or definite time can be selected. Refer to the
Time Curve Characteristics chapter.
BE1-11g Introduction
6 9424200994 Rev N
Note
Vector Jump (78) Protection
One vector jump protection element protects the generator by disconnecting it from the grid when a loss
of mains or mains failure occurs, preventing the generator from remaining tied to the mains if the mains
returns due to an external reclose device.
Frequency (81) Protection
Eight 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”.
BE1-11g protection systems enabled for IEC-61850 communication
(style Gxxxx5xxxxxxxx) have their frequency protection elements fixed
at four underfrequency elements, two overfrequency elements, and
two frequency rate-of-change elements.
Instantaneous Overcurrent (50) Protection
Directional overcurrent protection is provided by six instantaneous overcurrent elements. Digital signal
processing filters out unwanted harmonic components while providing fast overcurrent response with
limited transient overreach and overtravel.
Instantaneous overcurrent elements can be set for single-phase, three-phase, ground, neutral, positivesequence, 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.
Inverse Overcurrent (51) Protection
Seven inverse overcurrent elements can be set for single-phase, three-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.
Phase inverse overcurrent elements can be voltage restrained or controlled for generator backup
applications. 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 (style GxxxxxxxPxxxxx o r GxxxxxxxTxxxxx)
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.
Neutral Current Differ e nti al (87N) Protection (style GxxxxxxxPxxxxx or GxxxxxxxTxxxxx)
One neutral current differential element provides sensitive phase-to-ground fault differential protection for
the wye winding of the transformer.
Introduction BE1-11g
9424200994 Rev N 7
Note
Power (32) Protection
Two directional power elements are included in the BE1-11m and 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 is calibrated on a threephase 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.
BE1-11g protection systems enabled for IEC-61850 communication
(style Gxxxx5xxxxxxxx) have their power protection elements fixed at
one underpower element and one overpower element.
Loss of Excitation - Reverse Var Based (40Q) Protection
One loss of excitation element monitors three-phase reactive power (vars) to determine when a loss of
field condition exists.
Loss of Excitation - Impedance Based (40Z) Protection
One loss of excitation element implements a two zone offset mho characteristic to protect against varying
load conditions.
Distance (21) Protection
Two distance protection elements provide backup protection for external faults that are not cleared by
external protective relaying due to a failure of the external system protection scheme or equipment.
Settings are provided to configure a zone of reach using a mho circle.
Out of Step (78OOS) Protection
When a generator loses synchronism, high peak currents and off-frequency operation can cause winding
stress, high rotor iron currents, pulsating torques, and mechanical resonances that may be damaging to
the machine. The out of step element monitors the generator or step-up transformer terminals and detects
an out-of-step condition based on the rate of impedance change.
Resistance Temperature Detector (49RTD) Protection
Fourteen resistance temperature detector elements provide over/undertemperature protection in
applications where a remote RTD module is connected to the BE1-11g via Ethernet or RS-485 cable. For
more information, refer to the RTD Module chapter.
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 25, 27P, 47, 59P, and 51/27 functions.
Auto Synchronizer (25A) (style GxxxxxxxSxxxxx or GxxxxxxxTxxxxx)
An auto synchronizer element synchronizes a generator to a bus by matching the voltage, frequency, and
phase angle. Modes are provided for Phase Lock Loop or Anticipatory operation.
BE1-11g Introduction
8 9424200994 Rev N
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 BE1-11g 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.
Refer to the BESTlogicPlus chapter for more information on logic schemes. Custom logic settings allow
you to tailor the BE1-11g functionality to match the needs of your operation's practices and power system
requirements.
Metering Functions
Metering is provided for the following parameters:
• Primary and secondary voltages (P-P, P-N, V1, V2, 3V0, Vx, Vx 3
• Frequency (phase and auxiliary)
• Primary and secondary currents (phase, ground, I1, I2, 3I0)
• Power (real, reactive, app a r ent)

Programming the BE1-11g
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 BE1-11g. The
capabilities of BESTCOMSPlus make the configuration of one or several BE1-11g Generator 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 BE1-11g at the user’s convenience.
The BE1-11 plugin opens inside the B ESTCO M S Plus main shell. The same default logic scheme that is
shipped with the BE1-11g is brought into BESTCOMSPlus by downloading settings and logic from the
BE1-11g or by selecting application type “G” 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.
BESTlogic™Plus Programmable Logic is used to program BE1-11g 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 oscillography files can be accomplished using BESTwave
software.
Figure 9 illustrates the typical user interface components of the BE1-11 plugin with BESTCOMSPlus.

Click the View drop-down button to switch between the Settings Explorer and Metering Explorer or split
the view between both. The Settings Info Panel displays settings ranges. A workspace can be opened,
saved, or set as default. See Figure 10.

Summary Screens
Summary screens provide an overview of the system setup. The legend, located in the lower right-hand
corner, provides interpretation for the various indicated colors. The current state of a protection and
control function or element is indicated by the color of the adjacent indicator. If the function is enabled, the
color is green. If the function is disabled only by a setting (such as zero), the color is yellow. If the function
is disabled only by a mode, the color is blue. If the function is disabled by both a setting and mode, the
color is gray. The System Summary screen is available by clicking BE1-11 in the Settings Explorer as
shown in Figure 11. Summary screens are also available for General Settings, Alarm Configuration,
Protection, and Control.

Programming Example
Changing default logic is sometimes required to match the protection requirements of the system.
Additionally, elements must be enabled and operating settings set. This example demonstrates how to
configure typical nominal settings and program the 50-3 instantan eous ov erc ur rent elem ent. Sy s tem
nominal quantities are set to 69.3 volts and 3.6 amps. The 50-3 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 BE1-11g. See Figure 7.
Step 2: The BE1-11 Connection screen appears. See Figure 8. 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 BE1-11g to BESTCOMSPlus.
Step 4: Click on the View drop-down button and de-select Show Metering Panel and Show Setting
Information. See Figure 10. 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 Power System screen. See Figure 12.
Step 6: Under Nominal Settings, enter settings for Secondary Phase Voltage (69.3 V) and Secondary
Phase Current (3.6 A).
Figure 12. Power System Screen
Step 7: In the Settings Explorer, expand Protection, Current and select the Instantaneous Overcurrent
(50-3) screen. See Figure 13.
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 1 tab. See Figure 14. Examine the 50-3 element. The Logic 0 connected to
the Block input indicates that the 50-3 element is never blocked.
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 50-3 Trip.
This 50-3 Trip Off-Page Output is carried over to the Logic Page 2 tab (Figure 15) where it
becomes an Off-Page Input. The 50-3 Trip Off-Page Input and several others are AND gated to
the Trip Bus Off-Page Output which is carried over to the Logic Page 3 tab (Figure 16) where it
