1 Overview
The F-PRO (model 5100) is a microprocessor-based relay providing compre-
hensive directional overcurrent protection, reclosing, metering, breaker moni-
toring and recording functions suitable for medium and low voltage lines.
F-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 F-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

In addition to the protection functions F-PRO provides fault recording (96
sample/cycle) to facilitate analysis of the power system after a disturbance has
taken place. The triggers for fault recording are established by programming
the output matrix and allowing any internal relay function or any external input
to initiate recording.
The primary protection provided is overcurrent based. A library for these
overcurrent functions provides commonly used IEEE and IEC inverse curves.
Because the curves are equation-driven, you can choose to enter an equation
parameter directly, creating other overcurrent shapes as needed. All
overcurrent functions are provided with directional control, if required, using
the ERLPhase method of positive sequence control.

1 Overview

current inputs. Use F-PRO with straight single breaker line schemes by us-
ing the main current inputs
• breaker failure detection and monitoring
• 2 completely dedicated four shot reclosers devices 79 Main and 79 Aux to
control line reclosing needs along with device 25C Sync Check/Dead Bus/

D02416R04.00 F-PRO 5100 User Manual 2-1
2 Setup and Communications
Power Supply
A wide range power supply is standard. The nominal operating range is 48–250
Vdc, 120 Vac, 50/60 Hz. To protect against 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 station ground using the case-grounding terminal
at the back of the relay, for details see for details see Figure 1.3: F-PRO Back
View on page 1-3.
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.
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 enable or disable the IEEE 1344 extension in the terminal mode settings
Utilities>Setup>Time, for details see “Utilities” on page 3-14. The enabled
mode allows the year to be received from the IRIG-B signal. If the available
IRIG-B signal has no year extension, this setting should be disabled.

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 2-9.
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 Re-
lay’s SCADA Services” on page 2-8.

Figure 2.2: External Modem Link
The relay’s user interface can also be accessed through a telephone link be-
tween the relay and your computer, using an external modem.
Connect the serial port on the external modem to the Port 2 on the relay's back
panel. Both devices are configured as RS-232 DCE devices with female con-
nectors, so the cable between the relay and the modem requires a crossover and
a gender change. Alternatively, you can use the ERLPhase modem port adapter
provided with the relay to make Port 2 appear the same as a PC’s serial port. A
standard modem-to-PC serial cable can then be used to connect the modem and
the relay, for pin-out details see “Communication Port Details” on page 2-9.
Connect the modem to an analog telephone line or switch using a standard RJ-
11 connector.
To work with a modem, the relay’s Port 2 must be appropriately configured.
Log into the relay through a direct serial link, go to the Utilities>Setup>Ports
screen, and set the Port 2 Modem option to Yes. The Baud Rate should be set
as high as possible - most modems will handle 57,600 bps. The Initialize set-
ting lets you set the control codes sent to the modem at the start of each con-
nection session. The factory defaults are: “M0S0=0&B1” for an external
modem and “M0S0=0” for an internal modem.

You can access both the relay’s user interface and DNP3 SCADA services si-
multaneously through the same network port with an optional Ethernet TCP/IP
LAN link. If the Ethernet option has been installed, Port 5 on the rear panel will
be labelled “NETWORK.”
The user interface accessed through the LAN is the same as that available
through a direct serial connection or a modem link, but requires the use of a
Telnet client on your PC. The HyperTerminal program, which is included in
Windows XP and is also available separately as HyperTerminal PE, provides
Telnet services. To select Telnet, go to HyperTerminal’s Properties dialog box
and set the Connect Using field to TCP/IP (Winsock). If this option is not avail-

able in the pick list, you require a newer version of HyperTerminal (v1.2 or
greater). Alternatively, you can use any Telnet program that fully supports VT-
100 terminal emulation and z-modem file transfer.
DNP3 SCADA services can also be accessed over the LAN, for details see
“Accessing the Relay’s SCADA Services” on page 2-8.
Connect Port 5 to the Ethernet LAN using an appropriate 10BaseT cable with
an RJ-45 connector. The relay supports 10 Mbit Ethernet, although a dual
speed 10/100 Ethernet hub or switch can be used.
By default, the relay is assigned an IP address of 192.168.1.100. If this address
is not suitable, it may be modified using the relay’s , for details see “Using Hy-
perTerminal to Access the Relay’s User Interface” on page 2-5.
Using HyperTerminal to Access the Relay’s User Interface
Change settings, view measured values and retrieve data from the relay using
its user interface. This section describes how to configure a standard Windows
VT-100 terminal program on your PC for use with the relay.
The computer must be connected to the relay by one of its serial, modem or
Ethernet communication ports, for details see “Communicating with the Relay
(IED)” on page 2-2.
The relay user interface is accessed using a standard VT-100 terminal style
program on your computer eliminating the need for specialized user interface
software. Any terminal program that fully supports VT-100 emulation and pro-
vides z-modem file transfer services can be used. The HyperTerminal program
is used here as an example.
Configure your terminal program as described in the table below and link it to
the appropriate serial port, modem or TCP/IP socket on your computer.
Terminal Program Setup
Baud rate For a direct serial link, the baud rate must match that of the relay serial
port.
For a modem link, the baud rate refers only to the link between your
computer and its own modem.

When the connection is established, press Enter in the terminal window to
bring up the following login prompt:
Instructions on logging in and running the user interface are given in “Terminal
Mode” on page 3-5.
If you see incorrect characters on a direct serial connection, it may mean there
is a mismatch between the relay’s baud rate and that of the PC.
Ending a User
Interface Session Use the Quit function in the relay’s user menu to end a session. This will close
the interface and require the next user to log in to the relay.
The relay automatically ends a session when it detects the disconnecting of a
direct serial cable or a modem hang-up. For other types of connections (e.g. se-
rial switches or Ethernet) you are advised to use the Quit function to ensure the
interface is closed and login protection is activated.
Font Use a font that supports line drawing (e.g. Terminal or MS Line Draw).
If the menu appears outlined in odd characters, the font you have
selected is not supporting line drawing characters.
