Section 1 Introduction

About this chapter

This chapter is an introduction to the operator’s manual, its purpose and usage.

1.1 Introduction to the operator’s manual

1.1.1 About the complete set of manuals for an IED

The user’s manual (UM) is a complete set of five different manuals:

en06000097.vsd

Application

manual

Installation and

commissioning

manual

Operator´s

manual

Engineering

guide

The Application Manual (AM) contains application descriptions, setting guidelines

and setting parameters sorted per function. The application manual should be used to

find out when and for what purpose a typical protection function could be used. The

manual should also be used when calculating settings.

The Technical Reference Manual (TRM) contains application and functionality

descriptions and it lists function blocks, logic diagrams, input and output signals,

setting parameters and technical data sorted per function. The technical reference

manual should be used as a technical reference during the engineering phase,

installation and commissioning phase, and during normal service.

The Installation and Commissioning Manual (ICM) contains instructions on how

to install and commission the protection IED. The manual can also be used as a

reference during periodic testing. The manual covers procedures for mechanical and

electrical installation, energizing and checking of external circuitry, setting and

configuration as well as verifying settings and performing directional tests. The

chapters are organized in the chronological order (indicated by chapter/section

numbers) in which the protection IED should be installed and commissioned.

The Operator’s Manual (OM) contains instructions on how to operate the protection

IED during normal service once it has been commissioned. The operator’s manual

can be used to find out how to handle disturbances or how to view calculated and

measured network data in order to determine the cause of a fault.

• The chapter “Safety information” presents warnings and notices, which the user

should pay attention to.

• The chapter “Overview” describes operations an operator may perform on a daily

basis or when the need arises.

• The chapter “Understand the local human-machine interface” describes how to

use the human-machine interface.

• The chapter “Understand the HMI tree” describes the different menu trees.

• The chapter “Read measured values” describes how to locate and identify

available measurement data.

• The chapter “Event list” describes the location and nature of recorded events.

• The chapter “Handle disturbances” describes how to retrieve disturbance

information and reset alarms.

• The chapter “Read and change settings” describes how to locate, and change

settings and parameters.

• The chapter “Diagnose IED status” describes the location and use of available

diagnostic tools.

• The chapter “Test the IED” describes the tests applicable to the IED.

• The chapter “Control and supervise the bay” describes how to use the Single

Line Diagram to open and close primary apparatuses.

• The chapter “Reset” describes resetting procedures.

• The chapter “Authorization”describes user categories and password procedures.

• The chapter “Glossary” describes words and acronyms used in the literature

describing the IED.

This manual does not contain any instructions for commissioning or testing.

1.1.3 Intended audience

General

The operator’s manual addresses the operator, who operates the IED on a daily basis.

Requirement

The operator must be trained in and have a basic knowledge of how to operate

protection equipment. The manual contains terms and expressions commonly used

to describe this kind of equipment.

Section 2 Safety information

About this chapter

This chapter lists warnings and cautions that must be followed when handling the

IED.

2.1 Warnings

Do not touch circuitry during operation. Potentially lethal voltages

and currents are present.

Always connect the IED to protective earth, regardless of the

operating conditions. This also applies to special occasions such as

bench testing, demonstrations and off-site configuration. Operating

the IED without proper earthing may damage both IED and measuring

circuitry and may cause injuries in the event of an accident.

Never remove any screw from a powered IED or from a IED

connected to powered circuitry. Potentially lethal voltages and

currents are present.

Always avoid touching the circuitry when the cover is removed. The

product contains electronic circuitries which can be damaged if

exposed to static electricity (ESD). The electronic circuitries also

contain high voltage which is lethal to humans.

Section 3 Overview

About this chapter

This chapter presents a general overview of the Operator's manual.

3.1 Operator overview

The Human machine interface (HMI) on the IED provides an ideal mechanism for

the day to day operation and even advanced use of the IED. The keypad, LCD and

LEDs on the front of the IED are what constitute the HMI. Troubleshooting, apparatus

control, monitoring, setting and configuring are all possible via this interface.

Through the screens and menu elements available, as well as the keypad, the user is

able to navigate throughout the menu structure and move from screen to screen. This

document is, to a great extent, arranged in the same way as the IED software is

structured and describes all aspects of operation via the HMI.

The operator can document disturbances so that their causes can be analyzed and

evaluated for future reference. For example, the fault currents and voltages at the time

of the fault can be documented. The operator can also retrieve data about protected

objects, providing further information for fault analysis. This implies viewing the

mean value of current, voltage, power and frequency or primary and secondary

measured phasors. The operator can check the IED status at any time.

In some cases the operator may need to change the way the IED operates. This might

include changing the active setting group or a parameter value. This must always be

done strictly according to applicable regulations because un-authorized changes may

lead to severe damage of the protected object especially if a fault is not properly

disconnected.

3.2 Identify the IED

To identify the IED, open the diagnostics menu. The identity of the IED along with

other data is found under:

Diagnostics/IED status/Product Identifiers

The type of IED, the main function type, its serial number, ordering number and

production date are found here.
