The Eaton FP-5000 Protective Relay is a multifunction panel
mounted, microprocessor-based relay, designed for both ANSI
and IEC applications (Figure 1). It is a self-contained device which
operates from either ac or dc control power and provides true
rms sensing of each phase and ground current. Only one relay is
required per 3-phase circuit. Current, voltage and operator
selectable protective functions are integral to each device.The FP
5000 is designed to protect the mains, ties or feeders at any
voltage level. It is primarily applied on medium voltage
distribution circuits up to 69 kV. The FP-5000 monitors several
primary and derived electrical parameters of the system.
1.2 Audience
The audience for this document is the Specifying or System
Engineer, the operating personnel and the troubleshooting
personnel. This document will guide the system user to apply
and program the FP-5000. The document will provide operating
information, enabling the operating user to start and trip the
breaker associated with the FP-5000. The operator can refer to
this publication regarding any operation of the FP-5000. This
document will also provide information to program the FP-5000
and use the troubleshooting features to collect and analyze
historical, trending and oscillographic data.
1.3 Safety and Caution Notices/Disclaimers

1.6 FP-5000 Hardware Resources and Description
The FP-5000 has four current measuring inputs, four voltage
measuring inputs, eight contact inputs, seven contact output
relays, communications and a front panel user interface.
Based upon the firmware loaded into the flash memory of the
FP-5000 and the customer settings entered manually through the
front panel or through the RS-232 port using the PowerPort
program, the microprocessor observes inputs, sets outputs and
stores data for user retrieval
