Version Compatibility and Release History
This chart indicates the versions of Offliner Settings, RecordBase View and the
User Manual which are compatible with different versions of B-PRO firm-
ware.
RecordBase View and Offliner Settings are backward compatible with all ear-
lier versions of records and setting files. You can use RecordBase View to view
records produced by any version of B-PRO firmware and Offliner Settings can
create and edit older setting file versions.
Minor releases (designated with a letter suffix - e.g. v1.1a) maintain the same
compatibility as their base version. For example. B-PRO firmware v1.1b and
Offliner Settings v1.1a are compatible.

D01908R02.12 B-PRO User Manual 8700 1-1
1 Overview
The B-PRO (model 8700/BUS) is a microprocessor-based relay providing bus
differential protection, integrated breaker failure and overcurrent protection
functions, metering, fault and swing oscillography.
B-PRO has two working modes—online and offline. In the online mode you
can use any communication software package (e.g. Procomm or HyperTermi-
nal) to connect to the B-PRO using VT100 terminal emulation. In online mode
you can:
• change and review relay settings
• view event and metering information
• initiate and retrieve recordings, and retrieve settings
In offline mode you can use Offliner Settings and RecordBase View software
to:
• create and review relay settings
• analyze fault waveforms
• store records
The B-PRO relay provides differential protection (low-impedance) for the fol-
lowing types of bus configurations:
• 1 bus with up to six inputs and one set of voltage inputs (Figure ).
• 1 transformer zone with 2 inputs.
• 2 differential zones, 1 for a bus and 1 for a transformer (Figure ).
• 2 bus zones (Figure 1.3).
Backup feeder protection is provided for all inputs, regardless of which zone is
selected, even if an input is not used in a differential zone.

AC Current and
Voltage Inputs B-PRO is provided with terminal blocks for up to 18 ac currents and 3 phase
to neutral voltages.
Each of the current input circuits has polarity (•) marks.
A complete schematic of current and voltage circuits is shown, for details see
“AC Schematic Drawing” in Appendix I and “DC Schematic Drawing”
in Appendix J.
External Inputs The B-PRO relay contains 9 programmable external inputs. External dc volt-
age of either 48/125 volts or 125/250 volts nominal are possible depending on
the range provided.
To prevent an external input from picking up on spurious voltage pulses, a soft-
ware filter is applied to the input signals. The filter ignores logic high voltage
levels that occur for less than 2 milliseconds. This was increased from 700 mi-
croseconds in firmware version 2.1.
Output Relay
Contacts The B-PRO relay has 14 output relay contacts. Each contact is programmable
and has breaker tripping capability. All output contacts are isolated from each
other. The output contacts are closed for a minimum of 100 ms after operation.
Relay Inoperative
Alarm Output If the relay is in self check program or becomes inoperative, then the Relay In-
operative Alarm output contact closes and all tripping functions are blocked.

Model Options/Ordering
B-PRO is available as a horizontal mount, for details see “Mechanical Draw-
ings” in Appendix G.
B-PRO is available with an internal modem card or internal network card.
The CT inputs are 1 A nominal or 5 A nominal. The external inputs are 48/125
Vdc or 125/250 Vdc. The system base frequency is either 50 Hz or 60 Hz.
All of the above options must be specified at the time of ordering.

2 Setup and Communications
Power Supply
A wide range power supply is standard. The nominal operating range is 48 to
250 Vdc, 120 Vac, 50/60 Hz. To protect against a possible short circuit in the
supply use an inline fuse or circuit breaker with a 5 A rating. Make the chassis
ground connection to ensure proper operation and safety.
There are no power switches on the relay. When the power supply is connect-
ed, the relay starts its initialization process and takes about 40 seconds to com-
plete showing the green Relay Functional LED.
Case Grounding You must ground the relay to the station ground using the case-grounding ter-
minal at the back of the relay, for details see for details see Figure 1.4: B-PRO
Front View on page 1-3.
IRIG-B Time Input
The relay is equipped to handle modulated or unmodulated GPS satellite time
IRIG-B signals. The IRIG-B time signal is connected to the BNC connection
on the back of the relay. When the IRIG-B signal is provided to the relay and
is enabled in the settings through the user interface, the IRIG-B functional LED
comes on and the relay clock is referenced to this signal. No settings are re-
quired to differentiate between modulated or unmodulated signals; this is au-
tomatically detected by the relay.
You can enable or disable the IEEE 1344 extension in the terminal mode set-
tings Utilities>Setup>Time. The enabled mode receives the year from the
IRIG-B signal. Disable this setting, if the available IRIG-B signal has no year
extension.
WARNING!
To ensure safety and proper operation you must connect the relay to
the station ground using the rear grounding terminal on the relay.
Ground the relay even when testing.
Do not rely on the rack mounting screws to provide case grounding.

2 Setup and Communications
2-2 B-PRO User Manual 8700 D01908R02.12
Communicating with the Relay (IED)
You can connect to the relay to access its user interface and SCADA services
by:
• direct serial link (user interface and SCADA)
• external or internal modem link (user interface only)
• ethernet network link (user interface and SCADA)
Direct Serial Link
Figure 2.1: Direct Serial Link
The relay has three serial ports that provide direct access to its user interface
and SCADA services.
All of the relay’s serial ports (Ports 1, 2 and 3) are configured as EIA RS-232
Data Communications Equipment (DCE) devices with female DB9 connec-
tors. This allows them to be connected directly to a PC serial port with a stan-
dard straight-through male-to-female serial cable, for pin-out, for details see
“Communication Port Details” on page 2-8.
The relay’s user interface is accessed through a standard VT-100 terminal em-
ulation program running on a PC. To create a direct serial link between the re-
lay and your computer, connect the serial cable (provided) between your
computer's serial port and Port 1 on the relay’s front panel. Port 2 on the relay’s
back panel can also be used for direct serial access, provided the port is not
configured for modem use. When connected, run the terminal emulation soft-
ware on your computer to establish the communication link, for details see
“Using HyperTerminal to Access the Relay’s User Interface” on page 2-5.
The relay’s Modbus and DNP3 SCADA services can be accessed via a direct
serial link to Port 3 on the relay’s back panel, for details see “Accessing the
SCADA Services” on page 2-7.
