Version Compatibility
This chart indicates the versions of Offliner Settings, RecordBase View and
the User Manual which are compatible with different versions of L-PRO firm-
ware.
RecordBase View and Offliner Settings are backward compatible with all ear-
lier versions of records and setting files. Use RecordBase View to view records
produced by any version of L-PRO firmware and Offliner Settings can create
and edit older setting file versions.
Minor releases (designated with a letter suffix - e.g. v3.1a) maintain the same
compatibility as their base version. For example. L-PRO firmware v3.1c and
Offliner Settings v3.1a are compatible.
Please contact ERLPhase Customer Service for complete Revision History.

PC System Requirements and Software
Installation
Hardware
The minimum hardware requirements are:
• 1 GHz processor
• 2 GB RAM
• 20 GB available hard disk space
• USB port
• Serial communication port
Operating System
The following software must be installed and functional prior to installing the
applications:
• Microsoft Windows XP Professional Service Pack 3 or
• Microsoft Windows 7 Professional Service Pack 1 32-bit or 64-bit
Relay Control Panel requires Windows XP SP3 (it will not work on earlier ver-
sions of Windows).
Software Installation
The CD-ROM contains software and the User Manual for the L-PRO Trans-
mission Line Protection Relay.
Software is installed directly from the CD-ROM to a Windows PC. Alterna-
tively, create installation diskettes to install software on computers without a
CD-ROM drive.
The CD-ROM contains the following:
• L-PRO Offliner Settings: Offliner settings program for the relay
• L-PRO Firmware: Firmware and installation instructions
• L-PRO User Manual: L-PRO manual in PDF format
• L-PRO Function Logic Diagram: diagram in PDF format
• Relay Control Panel: software
• Relay Control Panel User Manual: manual in PDF format
• USB Driver
To Install Software on the Computer
Insert the CD-ROM in the drive. The CD-ROM should open automatically. If
the CD-ROM does not open automatically, go to Windows Explorer and find
the CD-ROM (usually on D drive). Open the ERLPhase.exe file to launch the
CD-ROM.

PC System Requirements and Software Installation
xiv L-PRO 4000 User Manual D02706R02.30
To install the software on the computer, click the desired item on the screen.
The installation program launches automatically. Installation may take a few
minutes to start.
To view the L-PRO User Manual the user must have Adobe Acrobat on the
computer. If a copy is needed, download a copy at www.adobe.com.
Anti-virus/Anti-spyware Software
If an anti-virus/anti-spyware software on your local system identifies any of
the ERLPhase applications as a “potential threat”, it will be necessary to con-
figure your anti-virus/anti-software to classify it as “safe” for its proper oper-
ation. Please consult the appropriate anti-virus/anti-spyware software
documentation to determine the relevant procedure.

1 Overview
1.1 Introduction
The L-PRO 4000 provides easy-to-use, state-of-the-art comprehensive dis-
tance and directional line protection for medium to extra-highvoltage transmis-
sion lines using communication-based schemes. It provides control,
automation, metering, monitoring, fault oscillography, dynamic swing record-
ing, event logging with advanced communications in a flexible cost effective
package.
The primary protection is line protection with 5 zones of phase and ground dis-
tance functions – user-defined Mho or Quadrilateral shapes and communica-
tions based schemes (i.e. teleprotection or pilot schemes).
To provide a complete package of protection and control the relay supplies oth-
er functions such as:
• 1.0 to 1.3 cycle operation at 80% reach, ideal for EHV transmission line
applications
• Ring bus capability – breaker failure and individual breaker monitoring
• 4-shot recloser with dead line/dead bus control and sync check
• Single pole and three pole trip and reclose
• 24 statements of ProLogic addresses special protection needs
• Power Swing Blocking / Tripping
• Load Encroachment
• Switch On To Fault function
• VT Supervision function
• CT Supervision function
• Over / Under Voltage functions
• 8 Setting Groups (SG) with setting group logic
• Back up Directional overcurrent and earth fault protection
• Over / Under / Rate of change of frequency devices
Relay Control Panel (RCP) is the Windows graphical user interface software
tool provided with all 3000, 4000 series and higher (new generation) ERL re-
lays to communicate, retrieve and manage records, event logs, fault logs, man-
age settings (identification, protection, SCADA etc.,), display real time
metering values, view, analyze, and export records in COMTRADE format.
In addition to the protection functions the relay provides fault recording (96
samples/cycle) to analyze faults and to review the operation of the overall pro-
tection scheme. The relay also has low speed swing recording which can be
used to analyze system stability. The triggers for fault recording are established

by programming the output matrix and allowing any internal relay function or
any external input or any GOOSE messaging input to initiate recording.
