Introduction
1.1.
About this manual
This manual provides basic information on the protection relay REF 610 and
presents detailed instructions on how to use the Human-Machine Interface (HMI) of
the relay, also known as the Man-Machine Interface (MMI). In addition to the
instructive part, a short chapter on commissioning and maintenance of the relay is
included.
1.2.
The use of the 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 has 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.
