Introduction

About this manual

This manual provides thorough information on the protection relay
and its applications
Revision B
refer to section "Revision history of the REF 610".
Refer to the Operator's Manual for instructions on how to use the
Human-Machine Interface (HMI) of the relay, also known as the Man-Machine
Interface (MMI), and to the Installation Manual for installation of the relay.

The use of the relay

The feeder protection relay REF 610 is a versatile multifunction protection relay
mainly designed to protect incoming and outgoing feeders in a wide range of feeder
applications.
REF 610 is based on a microprocessor environment. A self-supervision system
continuously monitors the operation of the relay.
The HMI includes a Liquid Crystal Display (LCD) which makes the local use of the
relay safe and easy.
Local control of the relay via serial communication can be carried out with a
computer connected to the front communication port. Remote control can be carried
out via the rear connector connected to the control and monitoring system through
the serial communication bus.
