4-4 BE1-BPR Functional Description 9272000990 Rev J
Output relays O1 through O5 are operated (energized) by the programmable logic section when the
corresponding logic equation is true. Table 4-2 lists the two logic equation states and the corresponding
hardware states.

Output relay O1 is a high-speed output with maximum operate time of 5 milliseconds.
Detailed target information about the inputs and outputs is displayed by the Targets menu screen.
Whenever any of the target output relays energize, the front panel Target LED lights. Target information is
latched in non-volatile memory if the output is programmed as latching. To reset the Target LED, operate
the front panel Reset pushbutton or enter the RESET command through a serial communication port. The
PTARGET command programs output relays as target relays.
Targets
A two line by 16 character, LCD shows targets, setup, status, and diagnostic information and allows
provides programming capability. LED backlighting illuminates the LCD screen.
Liquid Crystal Display (LCD)
Serial communication ports at the front and rear of the BE1-BPR provide total programming capability and
remote access for diagnostic, relay setup, and relay control.
Serial Ports RS-232/RS-485
SOFTWARE FUNCTIONAL DESCRIPTION
Most relay settings may be adjusted using the front panel keyboard and display. However, to program the
relay logic, change the breaker configuration data, time and date format, CT data, and request reports,
the front or rear communications port must be used. In general, tasks that are not easily performed at the
front panel should be done through the communication ports.
Introduction
Relay diagnostic and setup information is organized in a menu format when viewed using the front panel
display. Figure 4-2 shows the menu progression from startup to maintenance for an enhanced BE1-BPR.
Figure 4-3 shows the menu progression for a standard BE1-BPR. The right arrow key is used to scroll
through the available menu screens and the down arrow key is used to access menu sub-screens. When
using a communication port, the relay is programmed using ASCII software commands. Information about
software commands is available by using the HELP command. The HELP command provides a list of
available commands or information and syntax regarding a specific command along with an example of
its use.
HELP Commands Information HMI Menu Branch: N/A
Parameter Comments
Cmd HELP or H returns information about using the HELP command. HELP1 or H1
provides a list of relay commands. HELP or H, where is a
specific command, returns information on the usage and format of the
command and an example of its use.
