13 XPRESSION BUILDER
13 XPRESSION BUILDER 13.1 INTRODUCTION
The LPS-O relay has been designed to allow flexibility in the operation of contact converter inputs and contact
outputs. The inputs and outputs are not hard-wired to any function; the functions of each input and output are
defined by a software file which is downloaded to the relay as a part of each setting group.
The software file represents the linkage between the contact converters, internally generated protection flags,
and contact outputs; it contains information regarding the logical relationships among each entity. This file is
built using a windows based application called Xpression Builder.
Xpression Builder allows the utility engineer to design the interconnection of the inputs and outputs with Bool-
ean operators, latches, timers, and counters in a graphical environment. The application performs the task of
compiling the design from a graphical format, and allows the engineer to download the file to a relay setting
group with LPSO-Link. Each setting group can contain different Xpression Builder logic. The LPS-O comes
with a default Configurable Logic implementation.
If the LPS-O software suite has been installed from the Products CD or Web page, Xpression Builder may
already be installed. To install Xpression Builder by itself, consult the following procedure. Note that Microsoft
Windows must be installed on your PC before proceeding with the Xpression Builder Installation.
a) INSTALLING FROM PRODUCTS CD
To install Xpression Builder from the Products CD:
1. Start Windows.
2. Insert the GE Power Management Products CD into your local CD-ROM drive. The CD-ROM autorun utility
will automatically load the page shown in Figure 13–1: GEPM PRODUCTS CD PRIMARY SCREEN into
your default web browser.
