Introduction
1 Introduction to the operator’s manual
1.1 About the complete set of manuals for an IED

The user’s manual (UM) is a complete set of five different manuals:
Application Technical Installation and Operator´s Engineering

manual reference commissioning manual guide
manual manual
en06000097.vsd
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 tech-
nical data sorted per function. The technical reference manual should be used as a technical ref-
erence 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 per-
forming 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 dur-
ing 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 IED 670 engineering guide (EG) contains instructions on how to engineer the IED 670
products. The manual guides to use the different tool components for IED 670 engineering. It
also guides how to handle the tool component available to read disturbance files from the IEDs
on the basis of the IEC 61850 definitions. The third part is an introduction about the diagnostic
tool components available for IED 670 products and the PCM 600 tool.
1.2 About the operator’s manual

Use the operator’s manual for instruction on how to perform common tasks during normal ser-
vice.

Safety information
1 Warnings
Warning!
Do not touch circuitry during operation. Potentially lethal voltages and currents are present.
Warning!
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.
Warning!
Never remove any screw from a powered IED or from a IED connected to powered circuitry.
Potentially lethal voltages and currents are present.
Warning!
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 circuit-
ries also contain high voltage which is lethal to humans.

About this chapter

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

Operator overview Chapter 3
Overview
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 soft-
ware 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 doc-
umented. The operator can also retrieve data about protected objects, providing further informa-
tion 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 accord-
ing to applicable regulations because un-authorized changes may lead to severe damage of the
protected object especially if a fault is not properly disconnected.

graphical monochrome LCD which measures 120 x 90 mm. It has 28 lines with up to 40 char-
acters per line. To display the single line diagram, this LCD is required.
18
LED Chapter 4
5 LED
The LED module is a unidirectional means of communicating. This means that events may occur
that activate a LED in order to draw the operators attention to something that has occurred and
needs some sort of action.
5.1 Status indication LEDs

There are three LEDs above the LCD. The information they communicate is described in the
table below.
LED Indication Information

Green:
Steady In service
Flashing Internal failure
Dark No power supply
Yellow:
Steady Dist. rep. triggered
Flashing Terminal in test mode
Red:
Steady Trip command issued
5.2 Indication LEDs

The LED indication module comprising 15 LEDs is standard in IED 670s. Its main purpose is
to present an immediate visual information for protection indications or alarm signals.
There are alarm indication LEDs and hardware associated LEDs on the right hand side of the
front panel. The alarm LEDs are found to the right of the LCD screen. They can show steady or
flashing light. Flashing would normally indicate an alarm. The alarm LEDs are configurable us-
ing the PCM 600 tool. This is because they are dependent on the binary input logic and can there-
fore not be configured locally on the HMI. Some typical alarm examples follow:
• Bay controller failure

• CB close blocked
• Interlocking bypassed
• SF6 Gas refill
• Position error
• CB spring charge alarm
• Oil temperature alarm
• Thermal overload trip
The RJ45 port has a yellow LED indicating that communication has been established between
the IED and a computer.

About this chapter

This chapter describes measurement categories and how to locate them using the HMI. Each
measurement category has a section of its own that includes a general description of the type of
quantity being measured and the path in the local HMI to the measurement.
27
Overview Chapter 6
1 Overview
The measurement menu contains primarily analog measurement data. External signals can also
be viewed as they are or as they appear in the Signal Matrix Tool (SMT). These signals are a
virtual representation of the hard wired signals on the various inputs and outputs. The SMT is
only accessible via the PCM and is intended to simplify the configuration of the IED. It allows
hardware changes to made without having to reconfigure the internal logic. Signals that can be
used in the SMT are indicated with the Suffix SMT.
The functions available under measurements are outlined below.
1. Analog primary values are the quantities measured on the primary side of the cur-
rent and voltage transformers (CTs and VTs).
2. Analog secondary values are the quantities measured on the secondary side of the
current and voltage transformers. These are the quantities measured on the Trans-
former module (TRM) inputs.
3. Analog mean values are the quantities measured at the inputs of the milliampere
module (MIM).
4. Under Monitoring a number of submenus are available. These include Service
values, Current phasors, Voltage phasors, Current sequence components and
Voltage sequence components.
5. Metering displays the pulse counter function. The measurements available here
show pulse counter status data.
All measurement descriptions in this document reflect the maximum number of hardware units
possible in any application. In reality the hardware in the IED will be chosen according to a par-
ticular application. For example, it is possible to equip a 1/1 x 19” case IED with 14 I/O modules.
In reality fewer I/O modules may be installed. In the measurements menu the operator will only
see data from the hardware and software installed.

View analog primary values Chapter 6
2 View analog primary values
2.1 Overview
The analog primary values are analog quantities measured on the primary side of the TRM and
reflect the actual current or voltage on the primary side of the VTs and CTs. The ratio is adjusted
under settings and also depends on the rating of the TRM. 24 primary values and phase angles
are displayed in this view.
Measurements\Analog Primary Values
Displays the quantities measured by the transformer module (TRM). For each channel used the
amplitude of the voltage or current and its phase angle is shown. The status of the module is al-
ways shown and channels not in use are indicated with the abbreviation NC. Data from up to
two TRMs and four LDCMs can be viewed. All currents and voltages are given in RMS values.

4.1
Measurements from the Milliampere Input Module (MIM) are found in this part of the measure-
ments menu. Data from either the hard wired mA module or the Signal Matrix Tool mA modules
are shown here.
4.1.1 mA input module (MIM)

Measurements\Analog Mean Values\mA modules\Instance No.\AI
Displays input data from the milli-ampere module which has six inputs. Each input has a range
of +/- 20 mA. The value displayed on the screen is however dependant on the settings for the
Milli-ampere Module. In the menu for settings, the range and a transformation factor can be ad-
justed to suit the application. This means that an input 3 mA may be displayed as temperature
of 45 degrees. The output values shown are without units.
4.1.2 Signal matrix for mA inputs (SMMI)

Measurements\Mean Analog Values\SMT mA modules\Instance No.\AI
Displays the input signals coming into the Milli-ampere Module. Each module has six physical
inputs with an input tolerance of +/- 20mA. The value displayed depends on the settings applied
to this board which may for example cause an input of 3mA to show a value 30. The SMT mA
modules are the virtual representation of MIMs in the Signal Matrix Tool.

The current sequence component under monitoring displays the positive (I1), negative (I2) and
zero sequence (I0) current values for a three phase line, both magnitude and phase angle for each
component are displayed. These indicate how well balanced a system is. In an ideal balanced
system the zero sequence current should be zero, the positive sequence current should be equal
to the current of each phase with the same phase angle (relative to GPS) as the L1 phase signal
and the negative sequence current should be zero.
5.4 Voltage sequence component

Measurements\Monitoring\Voltage Sequence Components (MSQI)
The Voltage sequence component displays the positive (U1), negative (U2) and zero (U0) se-
quence components in the system, and includes the magnitude and phase angle of each compo-
nent. Three sets of values are shown. This data indicates how well balanced the system is.

This chapter describes disturbance detection and handling. This includes resetting LED alarms,
triggering disturbance reports, fault distance calculation and the viewing of several fault indica-
tors.

Identify a disturbance Chapter 8
Handle disturbances
1 Identify a disturbance
A disturbance record can be generated manually by using the Manual Trig functionality in the
HMI menu. Other disturbance records are generated automatically in the system dependant on
the settings made. Disturbance reports generate a disturbance sequence number and are time
tagged. The fault location and fault loop are among the data generated in a fault record. Under
each fault report there are five categories of information available. These are described in the
sections that follow.

records the screen generated displays information about the disturbance such as its sequence
number, time of occurrence, trig-signal, fault location and fault loop. The path in the HMI is
shown below.

current, voltage and phase angle can be viewed. The recording number and Trig time are also
displayed. The path in the HMI is shown below.
Disturbance records\Record xx\Trip Values
2.5 Recalculate distance to fault

This screen displays the fault loop with reactance and resistance values. To recalculate the dis-
tance to fault, press the E key on the keypad.
In the Recalculate distance to fault section in a disturbance record it is possible not only to view
fault data but to recalculate the distance to a fault. By taking into account peripheral influences
like the resistance and reactance of other lines in the immediate network area new distances can
be calculated. The reactance and resistance in the forward direction have the suffix B and in the
reverse direction they have the suffix A.
Recalculation may be necessary in cases where the data from a different fault loop needs to be
calculated. In three phase faults only one loop is shown in the disturbance record. When recal-
culating, a different fault loop can be selected. The path in the HMI is shown below.

About this chapter

This chapter describes how to find and change settings and parameters. The chapter is divided
into two sections which match the way the two categories of settings are divided up in the HMI.
The General settings group consists of those parameters that cause an automatic restart of the
IED. The Setting group N consists of six groups of settings with default values for all parame-
ters. These do not require or cause a restart once they have been changed. Time, synchronization
and the activation of setting groups are also dealt with here.

In the General submenu there are three settings. These are for the Subnet address, the Node ad-
dress and the NeuronID.
Settings\General settings\Communication\SLM\
Rear optical LON port\ServicePinMessage
In this submenu a Service pin message can be generated. This is similar to a “ping” in traditional
networks. This sends a signal to another node in the system which is then made aware of the
Neuron ID of LON port and can respond to that port.
Settings\General settings\Communication\SLM\Rear optical LON port\ADE
The Application Data Event (ADE) menu is where operation of LON is set on or off and where
the data exchange speed can be set. If LON is used primarily to send event data then the appro-
priate setting is slow. Should LON be used, for example, as a channel for TRIP signals then the
setting fast would be appropriate.

2.3 Analog modules

2.3.1 Overview
Under Analog modules in the General settings menu there are settings for Analog inputs and I/O
modules. Within each instance of analog input there are settings for all 12 channels that include
the name of the channel, star point of the CT circuit, the primary and secondary values from the
measuring transformers (CTs and VTs). The channel type and ratings are shown but cannot be
changed.
The settings for binary inputs and outputs even include the milliampere input modules. A mix
of up to 14 instances of BIM, BOM and IOM is possible depending on the physical configuration
of the IED. Operation ON or OFF can be set for all of these and for the BIMs oscillation release
and oscillation block settings are available. These settings are on board level and apply to all bi-
nary inputs or outputs on a board.
2.3.2 Analog modules

Settings\General Settings\Analog modules\AnalogInputs
Displays all variations of analog input modules with parameters. The analog input modules have
different combinations of current and voltage inputs. Each channel has parameters where the
type of channel is set, the primary and secondary values from VTs and CTs and for Current
Transformers the star point location (line side or busbar side) is set.
2.3.3 I/O modules

Settings\General Settings\I/O Modules
Settings for binary inputs and outputs (BIM, BOM, IOM), and under each binary module there
are one or more adjustable parameters. In the I/O modules folder there is also a “reconfigure”
setting that starts a dialog box prompting the user to confirm or cancel the command. Since only
I/O modules installed in the IED are shown, the parameters available for setting depend on the
physical configuration of the IED. All I/O modules include the operation parameter which en-
ables the operator to switch the module on or off.
The milliampere modules (MIMs) are also found in the I/O Modules folder. Parameters possible
to set here are dead band settings and various current threshold values.
2.4 HMI

About this chapter

This chapter describes the various control and supervision functions available in the HMI. In
particular, how the single line diagram available on the display can be used for this purpose. It
also describes the Selector switch function available under the control menu.
91
Overview Chapter 12
1 Overview
The control menu in the HMI includes the Single line diagram, Single command and Selector
switch functions.
The Single Line Diagram (SLD) is used to control and supervise the bay by allowing the oper-
ator to close and open apparatuses using keys on the front panel of the IED. This is primarily
intended as a backup for higher level control systems. If for example MicroSCADA were to mal-
function, then bay level switches and circuit breakers can be controlled directly from the HMI.
The Single command function is used to view LON interlocking data and is only visible if LON
is configured and used in the system.
The Selector Switch function is configured in the PCM 600 tool and the switch position can be
changed in the HMI. The selector switch has the same function as a rotating switch with up to
32 positions. Each position is configured in the PCM 600 to match a certain application. Each
position number corresponds to the equivalent position of a rotating switch. It is only visible if
it has been configured in the PCM 600.
1.1 Read measured values and check apparatus status

In the single line diagram a number of measured quantities are displayed. These are normally
system voltage (U), system current (I), active power (P) and reactive power (Q). They are dis-
played on the right hand side of the SLD graphic. The quantities shown can be configured in the
PCM and may therefore not always have the same appearance in different IEDs.
1.2 Locating and using the single line diagram

It is possible to navigate the SLD screen using the up and down keys on the IED keypad. The
apparatus under control is highlighted as the user moves from symbol to symbol using the key-
pad. An apparatus is opened using the green O key and closed using the red I key.

1.3 Control screen messages

These messages appear at the bottom of the SLD screen and are in the form of a prompt asking
the user to confirm an action, such as the opening of a circuit breaker. They can also warn the
user as to conditions that are a hindrance to the intended action, such as an interlocking condi-
tion. The user may be given the choice to override certain conditions.

The Administrator submenu allows the administrator to log on, log off, edit own data, add new
users, edit users and delete users. The HMI path is as follows:

1.1 To log in as administrator

Write abb in place of the three first * symbols. Place the cursor at the fourth * symbol. Press the
"down arrow" until the $ symbol appears directly behind abb. Enter
1.2 User categories

There are three different user categories, these are listed below:
• Super user (Unlimited access)

• Administrator (Admin. only)
• Control safeAction (Limited access)
The users are categorized according to the level of access they are allowed in the system. The
super user is the default setting. The super user has unlimited access to the HMI. The adminis-
trator user category can create new users, change passwords, access settings but cannot exercise
direct apparatus control. The Control safeAction category of user can open and close breakers,
disconnectors and the like via the HMI but has no access to settings and cannot manoeuvre an
apparatus which is interlocked.
User access can be limited to certain places and to certain levels in the control system. This is
known as place authority. In multi-level control systems there are control points on different lev-
els in the system. It may be desirable to have a certain category of user at a remote locality such
as the network control centre (SCADA). Other users may be placed at the station operator WPL
(MICROSCADA). Both are remote in relation to the IED.
The control IED is provided with a control switch that can be set to LOCAL, REMOTE or OFF.
OFF means that no operator place is allocated.
LOCAL means that the IED is controlled locally via the HMI or local panel (PC or similar).
REMOTE means that the IED is controlled from a higher level location such as the substation
control centre (MICROSCADA) or network control centre (SCADA). Settings can still be done
locally but all control functions are lifted to the next level in the control hierarchy.
Parameter setting can always be done at all levels. It is the capability to execute control functions
that is moved from place to place.

Instance When several occurrences of the same function are available in the IED
they are referred to as instances of that function. One instance of a func-
tion is identical to another of the same kind but will have a different num-
ber in the IED user interfaces. The word instance is sometimes defined
as an item of information that is representative of a type. In the same
way an instance of a function in the IED is representative of a type of
function.

Overreach A term used to describe how the relay behaves during a fault condition.
For example a distance relay is over-reaching when the impedance pre-
sented to it is smaller than the apparent impedance to the fault applied
to the balance point, i.e. the set reach. The relay “sees” the fault but per-
haps it should not have seen it.

TCS Trip circuit supervision
TCP Transmission control protocol. The most common transport layer proto-
col used on Ethernet and the Internet.
TCP/IP Transmission control protocol over Internet Protocol. The de facto stan-
dard Ethernet protocols incorporated into 4.2BSD Unix. TCP/IP was
developed by DARPA for internet working and encompasses both net-
work layer and transport layer protocols. While TCP and IP specify two
protocols at specific protocol layers, TCP/IP is often used to refer to the
entire US Department of Defense protocol suite based upon these,
including Telnet, FTP, UDP and RDP.
TEF Time delayed earth-fault protection function
TNC connector Threaded Neill Concelman, A threaded constant impedance version of a

BNC connector
TPZ, TPY, TPX, TPS Current transformer class according to IEC
Underreach A term used to describe how the relay behaves during a fault condition.
For example a distance relay is under-reaching when the impedance
presented to it is greater than the apparent impedance to the fault
applied to the balance point, i.e. the set reach. The relay does not “see”
the fault but perhaps it should have seen it. See also Overreach.
U/I-PISA Process interface components that deliver measured voltage and cur-
rent values
UTC Coordinated universal time. A coordinated time scale, maintained by the

Bureau International des Poids et Mesures (BIPM), which forms the
basis of a coordinated dissemination of standard frequencies and time
signals. UTC is derived from International Atomic Time (TAI) by the addi-
tion of a whole number of "leap seconds" to synchronize it with Universal
Time 1 (UT1), thus allowing for the eccentricity of the Earth's orbit, the
rotational axis tilt (23.5 degrees), but still showing the Earth's irregular
rotation, on which UT1 is based. The Coordinated Universal Time is
expressed using a 24-hour clock and uses the Gregorian calendar. It is
used for aeroplane and ship navigation, where it also sometimes known
by the military name, "Zulu time". "Zulu" in the phonetic alphabet stands
for "Z" which stands for longitude zero.
UV Undervoltage
V.36 CCITT interface for 4 wire data communication with a speed exceeding
48Kkbps.
WEI Weak end infeed logic
VT Voltage transformer
X.21 A digital signalling interface primarily used for telecom equipment
3IO Three times zero-sequence current. Often referred to as the residual or

the earth-fault current
3UO Three times the zero sequence voltage. Often referred to as the residual
voltage or the neutral point voltage
