SECTION 2 • QUICK START
GENERAL
This section provides an overview of the BE1-951 Utility Multifunction Relay. You should be familiar with
the concepts behind the user interfaces and BESTlogic before you begin reading about the detailed BE1-
951 functions. Sections 3 through 6 in the instruction manual describe each function of the BE1-951 in
detail.
The following information is intended to provide the reader with a basic understanding of the user
interfaces and the security features provided in the BE1-951 relay. Detailed information on the operation
of the human-machine interface (HMI) can be found in Section 10, Human-Machine Interface, and the
ASCII command communications in Section 11, ASCII Command Interface. BESTCOMS is a Windows
®
based software application that enhances communication between the PC user and the BE1-951 relay.
BESTCOMS for the BE1-951 is provided free of charge with the BE1-951. BESTCOMS operation is very
transparent, and does contain a Windows
®
type help file for additional operational details.
Also covered in this section is an overview of BESTlogic, which is fundamental to how each of the
protection and control functions is set-up and used in the BE1-951 relay. Detailed information on using
BESTlogic to design complete protection and control schemes for the protected circuit can be found in
Section 7, BESTlogic Programmable Logic, and Section 8, Application.
Sections 3 through 6 describe each function provided in the BE1-951 relay and include references to the
following items. Note that not all items are appropriate for each function.
• Human-machine interface (HMI) screens for setting the operational parameters.
• ASCII commands for setting the operational parameters.
• ASCII commands for setting up the BESTlogic required to use the function in your protection and
control scheme.
• Outputs from the function such as alarm and BESTlogic variables or data reports.
• HMI screens for operation or interrogation of the outputs and reports provided by each function.
• ASCII commands for operation or interrogation of the outputs and reports provided by each
function.
About This Manual
The various application functions provided by this multifunction relay are divided into four categories:
input/output functions, protection and control functions, metering functions, and reporting and alarm
functions. Detailed descriptions of each individual function, setup, and use are covered in the sections as
shown in
Table 2-1. Detailed information on using programmable logic to create your own protection and
control scheme is described in Section 7, BESTlogic Programmable Logic.
