Introduction

1 Introduction to the technical reference manual

1.1 About the complete set of manuals for an IEDThe users manual (UM) is a complete set of four different manuals:

The Application Manual (AM)contains application descriptions, setting guidelines and settingparameters sorted per function. The application manual should be used to find out when and forwhat purpose a typical protection function could be used. The manual should also be used whencalculating settings.

The Technical Reference Manual (TRM)contains application and functionality descriptionsand 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 normalservice.

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 periodictesting. The manual covers procedures for mechanical and electrical installation, energizing andchecking 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 bychapter/section numbers) in which the protection IED should be installed and commissioned.

The Operators Manual (OM)contains instructions on how to operate the protection IED dur-ing normal service once it has been commissioned. The operators manual can be used to findout how to handle disturbances or how to view calculated and measured network data in orderto determine the cause of a fault.

1.2 About the technical reference manual

The technical reference manual contains the following chapters:

Thechapter IED Overviewdescribes the IED in general.

The chapter Local human-machine interfacedescribes the control panel on theIED. Display characteristics, control keys and various local human-machine in-terface features are explained.

1.3.1 Introduction

Outlines the implementation of a particular protection function.

Introduction

1.3.2 Principle of operation

Describes how the function works, presents a general background to algorithms and measure-ment techniques. Logic diagrams are used to illustrate functionality.

Logic diagrams

Logic diagrams describe the signal logic inside the function block and are bordered by dashedlines.

Signal names

Input and output logic signals consist of two groups of letters separated by two dashes. The firstgroup consists of up to four letters and presents the abbreviated name for the correspondingfunction. The second group presents the functionality of the particular signal. According to thisexplanation, the meaning of the signal BLKTR in figure 4is as follows:

BLKTR informs the user that the signal will BLOCK the TRIP command fromthe under-voltage function, when its value is a logical one (1).

Input signals are always on the left hand side, and output signals on the right hand side. Settingsare not displayed.

Input and output signals

In a logic diagram, input and output signal paths are shown as a lines that touch the outer borderof the diagram.

Input and output signals can be configured using the CAP531 tool. They can be connected to theinputs and outputs of other functions and to binary inputs and outputs. Examples of input signalsare BLKTR, BLOCK and VTSU. Examples output signals are TRIP, START, STL1, STL2,STL3.

Setting parametersSignals in frames with a shaded area on their right hand side represent setting parameter signals.These parameters can only be set via the PST or LHMI. Their values are high (1) only when thecorresponding setting parameter is set to the symbolic value specified within the frame. Exampleis the signal Block TUV=Yes. Their logical values correspond automatically to the selected set-ting value.

Internal signals

Internal signals are illustrated graphically and end approximately. 2 mm from the frame edge. Ifan internal signal path cannot be drawn with a continuous line, the suffix -int is added to the sig-nal name to indicate where the signal starts and continues, see figure 3.

Human machine interface Chapter 2


1 Human machine interface

The local human machine interface is available in a small, and a medium sized model. The prin-ciple difference between the two is the size of the LCD. The small size LCD has a four lines andthe medium size LCD can display the single line diagram with up to 15 objects.

The local human machine interface is equipped with an LCD that can display the single line di-agram with up to 15 objects.

The local human-machine interface is simple and easy to understand the whole front plate isdivided into zones, each of them with a well-defined functionality:

Status indication LEDs

Alarm indication LEDs which consists of 15 LEDs (6 red and 9 yellow) with userprintable label. All LEDs are configurable from the PCM600 tool

LED Chapter 2

5.1 IntroductionThe LED module is a unidirectional means of communicating. This means that events may occurthat activate a LED in order to draw the operators attention to something that has occurred andneeds some sort of action.

5.2 Status indication LEDs

There are three LEDs above the LCD. The information they communicate is described in thetable below.

5.3 Indication LEDs

The LED indication module comprising 15 LEDs is standard in REx670 IEDs. Its main purposeis 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 thefront panel. The alarm LEDs are found to the right of the LCD screen. They can show steady orflashing light. Flashing would normally indicate an alarm. The alarm LEDs are configurable us-ing the PCM600 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

Differential protection trip

SF6 Gas refill

Position error

CB spring charge alarm

Oil temperature alarm

Thermal overload trip

6.4 Indication LEDs

6.4.1 Introduction

The function block HLED (LEDMonitor) controls and supplies information about the status ofthe indication LEDs. The input and output signals of HLED are configured with the PCM600tool. The input signal for each LED is selected individually with the PCM600 Signal MatrixTool (SMT). LEDs (number 16) for trip indications are red and LEDs (number 715) for startindications are yellow.

Each indication LED on the LHMI can be set individually to operate in six different sequences;two as follow type and four as latch type. Two of the latching types are intended to be used as aprotection indication system, either in collecting or restarting mode, with reset functionality. Theother two are intended to be used as signalling system in collecting (coll) mode with an acknowl-edgment functionality. The light from the LEDs can be steady (-S) or flickering (-F).

6.4.2 Design

The information on the LEDs is stored at loss of the auxiliary power to the IED. The latest LEDpicture appears immediately after the IED is successfully restarted.

Operating modes

Collecting mode

- LEDs which are used in collecting mode of operation are accumulated con-

tinuously until the unit is acknowledged manually. This mode is suitablewhen the LEDs are used as a simplified alarm system.

Re-starting mode

- In the re-starting mode of operation each new start resets all previous activeLEDs and activates only those which appear during one disturbance. OnlyLEDs defined for re-starting mode with the latched sequence type 6 (Latche-dReset-S) will initiate a reset and a restart at a new disturbance. A distur-bance is defined to end a settable time after the reset of the activated inputsignals or when the maximum time limit has been elapsed.

Acknowledgment /reset

From local HMI

- The active indications can be acknowledged/reset manually. Manual ac-knowledgment and manual reset have the same meaning and is a commonsignal for all the operating sequences and LEDs. The function is positiveedge triggered, not level triggered. The acknowledgment/reset is performedvia the Reset-button and menus on the LHMI. For details, refer to the Op-erators manual.

From function input

- The active indications can also be acknowledged/reset from an input, RE-SET, to the function. This input can for example be configured to a binaryinput operated from an external push button. The function is positive edgetriggered, not level triggered. This means that even if the button is continu-

ously pressed, the acknowledgment/reset only affects indica
