1.3 CUSTOM PROGRAMMABILITY 1.3.1 INTRODUCTION
The LPS-O offers a high degree of custom programmability. Custom programming of the LPS-O relay is
accomplished using the Xpression Builder software. Xpression Builder is a Windows based program that
allows the user to graphically design Programmable Logic and create I/O (Input/Output) assignments for the
LPS-O and other GE Power Management relays. Xpression Builder is included on the GE Power Management
CD-ROM or may be downloaded from the GE Power Management website. A complete description of the LPS-
O custom programming features and Xpression Builder is included in Chapter 13: XPRESSION BUILDER
.
