Introduction - GE ALPS Instruction Manual

1 PRODUCT DESCRIPTION
1.3 CUSTOM PROGRAMMABILITY
The ALPS offers a high degree of custom programmability. Custom programming of the ALPS is accomplished using
Xpression Builder. Xpression Builder is a Windows based program that allows the user to design programmable logic and
make I/O (Input/Output) assignments for the ALPS and other GE Power Management relays. Xpression Builder is included
with ALPS software suite on the GE Power Management CD. A complete description of Xpression Builder is included in
Chapter 13: XPRESSION BUILDER.
In addition to the pre-programmed line protection schemes and configurable I/O, the ALPS relay includes the capability for
the user to design custom logic. This logic may be used to supplement or to replace the built-in scheme logic. The program-
mable logic includes the following: up to 40 logic gates (AND, OR, NOT), each with up to 4 inputs; 8 programmable timers
each with a settable pickup and dropout delay; 8 counters; and 8 latches.
All of the contact converters (Digital Inputs) in the ALPS are user configurable. However, each ALPS relay is shipped with
Default Contact Converter Assignments as shown below and on the default elementary diagrams on pages 1–49 to 1–52.
Each configurable input can be assigned only one flag – assigning more than one flag to a configurable
input may cause maloperation!
