1 EBR‑3000 High Impedance Differential ProtectionRelayThe EBR‑3Z (i. e. an EBR-3000 relay combined with an EBR‑Z) is a digital protectionrelay designed for the high impedance differential protection scheme.

The intuitive operating concept with plausibility checks and extensive commissioningfunctions such as the built-in fault simulator allows a safe and time-optimizedmaintenance and commissioning. The parameter setting and evaluation softwarePowerPort-E can be used consistently across the entire family of devices.

General Description

The principle of the High Impedance Differential protection is comparable with the LowImpedance Differential Protection: Calculate and monitor the sum of all the currentsflowing into the protected object, and under non-fault conditions the sum is zero. Anydifferential current, however, is forced through the high impedance of the HighImpedance Relay.

The input of the High Impedance Relay consists of a resistance (EBR‑Z) and anovercurrent protection element (ANSI 87 in the EBR-3000).

The following convention is important to know: Even though the EBR-3000 measures thecurrents flowing through the stabilizing resistor, all the measurements are presented as avoltage across this stabilizing resistor (which is 2000 Ω for the EBR‑Z). The burden ofthe EBR-3000 measuring input (which is in series with the EBR‑Z resistor) can beneglected compared to these 2000 Ω.

The EBR-3000 monitors the magnitude of this voltage to differentiate between in-zoneand through faults.

An array of varistors is built into the EBR‑Z. It is connected across the input of the relayto avoid that the relay gets damaged by high voltage. The varistors need to be able toconduct significant power. The paralleled CTs deliver the current under special faultcircumstances (e. g. in case of a breaker failure) for more than 30 cycles.

In particular, the order variant EBR‑Z‑2A features two varistors per phase, energy rating5200 W⋅s, whereas the order variant EBR‑Z‑2B features four varistors per phase, energyrating 10400 W⋅s. For technical details see ╚═▷ “11.2 Technical Data EBR‑Z”, thecomplete ordering options can be found here: ╚═▷ “1.2.5 Catalog Codes for the EBR‑3Z”(or, for a stand-alone EBR‑Z: ╚═▷ “1.2.7 Catalog Codes for the EBR‑Z”).

A solution to reduce the energy absorption requirements is to short-circuit the highimpedance input via a lockout relay (which is closed as soon as a trip occurs). (Somemore detailed considerations about the thermal energy, including example calculations,can be found in the Protection chapter, see ╚═▷ “4.2.1 Calculation of the ThermalDimensioning of the MOV”.)

NOTICE!

Note that the concept of High Impedance Differential protection implies somerequirements to the connected CTs, especially:

• All CTs connected to the High Impedance Module must have the same ratio,accuracy class and construction.

• All the CTs must be connected in parallel.• The point where all the CTs tie together should be equidistant from all CTs.• The burden rating/saturation voltage must be sized appropriately.• No other equipment can be connected to the CT outputs.

External Fault

During an external fault or during normal load condition, and if the current transformershave the same ratio and if no current transformer saturation occurs, the current circulatesaround the CTs and no or only very little current will flow through the relay.

During a through-fault condition (external fault), the current transformer at the faultedfeeder carries the highest amount of current. This CT is the first candidate for CTsaturation. To prevent false tripping, the threshold of the High Impedance DifferentialRelay (87) must be above the current that is driven through the relay path in the case of acompletely saturated current transformer.

For a completely saturated current transformer the current output is zero. A saturated CTcan be seen as a short-circuit with a small resistance. The stabilization impedance (of theEBR‑Z) in series with the relay forces the differential current to flow through the saturatedCT, instead of through the relay. The stabilization resistance is much higher than the CTresistance. The relay threshold must be above the voltage across the resistor that canoccur in case of the worst-possible external fault.



Internal Fault

An internal bus fault is fed by all current sources. On the secondary side, the equivalentcurrent flows into the High Impedance Differential Relay. The voltage across the resistorexceeds the pickup value, so that the relay trips.

As this current produces a very high voltage across the resistor, a varistor has to be usedto restrict this hazardous voltage. At internal faults, the CTs saturate because of the highresistance in the relay path.

High Impedance Applications

The high impedance differential protection scheme is used for example for single busbarapplications, for three phase differential protection of generator, motors or transformersor for restricted and balanced ground fault applications, see principle diagram in ╚═▷Fig. 1 above.

It is, however, also usable for the following applications:

• Three phase differential protection of transformers, generators, motors, etc.

• Restricted earth fault protection for grounded-wye windings or balanced earth faultprotection applications.

High Impedance Restricted Earth/Ground Fault protection is often used if the star point ofa winding is grounded.

High Impedance Differential Protection can also be used to protect the delta winding in agrounded network. This is sometimes called “Balanced Earth Fault Protection” (BEF).

Structure of This Manual

• Safety first! Make yourself familiar with the most important safety messages usedthroughout this manual: ╚═▷ “1.1.1 Important Definitions”. Moreover, there isgeneral information about the delivery scope (╚═▷ “1.2 Information About theDevice”) and this manual and the conventions and symbols used here (╚═▷ “1.1.2Symbols and Definitions”).


1 EBR‑3000 High Impedance Differential Protection Relay1.1 Comments on the Manual

• A general overview of the protection functions available with the EBR-3000 can befound as a function diagram: ╚═▷ “1.2.8 EBR-3000 Functional Overview”. Note thatthe availability of some functions depends on the ordered device type. See ╚═▷“1.2.6 Catalog Codes for the EBR-3000” for the available variants.

• The EBR-3000 uses a special modular concept for its settings, measured values andsignals. Although this concept of modules and parameters is simple and straight-forward it is strongly recommended, especially for beginners, to make oneselffamiliar with it: ╚═▷ “1.3 Modules, Settings, Signals and Values”

• PowerPort-E is the operating program that can be installed on a Windows PC. It canconnect to the EBR-3000, and it can be used to do configuration work and retrievedata (measuring and statistics values, fault records, etc.) from the EBR-3000. A fewintroductory words are here: ╚═▷ “1.8 PowerPort-E”; however, for a detaileddescription you can consult the full PowerPort-E Manual as a separate document.

• The hardware aspects (e. g. dimension diagrams and connection diagrams) can befound here: ╚═▷ “2 Hardware”

• Various Security settings might have to be done, because the EBR-3000 is deliveredwith no access restrictions and a very simple standard password that does not offerany safety at all. Unless you are sure that no special access restrictions are requiredfor your application, it is strictly recommended to check the “Security” chapter: ╚═▷“1.4 Security”

• A few settings are related to the EBR-3000 itself: ╚═▷ “1.3.7 Device Parameters”

• The EBR-3000 makes a lot of measured values available and maintains statistics ofsome more values: ╚═▷ “1.6 Measuring Values” and ╚═▷ “1.7 Statistics” describewhat concepts and settings are related to this.

• The various communication protocols that the EBR-3000 makes available forcommunicating with the substation are described in ╚═▷ “3 CommunicationProtocols”.

• The usual application for a EBR-3000 involves various Breakers shall be tripped bythe protection functions in case of a fault. This is implemented by having thesetriggered by a “86” Lockout Relay, which is connected to the EBR-3000 and trippedin case of a fault. Optionally, a second Lockout Relay can be added, which is used toshort-circuit the CTs (and thus protect them from the hazardous effect of the highvoltages that can occur in case of fault). The concepts related to the control of theLockout Relays is described in ╚═▷ “5 Control / Lockout Relays”.

• The multitude of protection functions is described in sub-chapters within the“Protection Functions” chapter: ╚═▷ “4 Protective Elements”. Keep in mind that thereis one “master protection” module that governs all protection functions: ╚═▷ “4.1Protection (Prot) Module”. And furthermore, it is not only important to know how toactivate a protection module, it is also essential to know about the blocking of amodule: ╚═▷ “4.1.1 Blockings”

• Various kinds of events (disturbances, detected faults, etc.) are recorded by theEBR-3000, so that you need to know how to access these records: ╚═▷ “6 Recorders”

• The EBR-3000 offers programmable logic equations for programming inputs, outputs,blocking of protective functions, and custom logic functions in the relay: ╚═▷ “7Programmable Logic”



• In addition to the various protection functions, the EBR-3000 also features varioussupervision functions. The main difference is that – contrast to a protectionfunction – a supervision function does not issue any trip signal, but generates analarm signal under special circumstances. This alarm signal can be used to blockprotection functions, or it can be assigned to any of the LEDs or some output: ╚═▷ “8Supervision”

• Commissioning aspects for the EBR-3000: ╚═▷ “9 Commissioning”. But note thatprotection-specific commissioning descriptions are sub-chapters within therespective chapters for the protection functions.

• Technical data, tolerances, and applicable standards: ╚═▷ “11.1 Technical DataEBR-3000”

WARNING!

FOLLOW INSTRUCTIONS

Read this entire manual and all other publications pertaining to the work to be performedbefore installing, operating, or servicing this equipment. Practice all plant and safetyinstructions and precautions. Failure to follow the instructions can cause personal injuryand/or property damage.



WARNING!

PROPER USE

Any unauthorized modifications to or use of this equipment outside its specifiedmechanical, electrical, or other operating limits may cause personal injury and/orproperty damage, including damage to the equipment. Any such unauthorizedmodifications: (1) constitute “misuse” and/or “negligence” within the meaning of theproduct warranty, thereby excluding warranty coverage for any resulting damage; and (2)invalidate product certifications or listings.

The programmable devices subject to this manual are designed for protection and alsocontrol of power installations and operational devices that are fed by voltage sources witha fixed frequency, i.e. fixed at 50 or 60 Hertz. They are not intended for use with VariableFrequency Drives. The devices are further designed for installation in low voltage (LV)compartments of medium voltage (MV) switchgear panels or in de-centralized protectionpanels. The programming and settings have to meet all requirements of the protectionconcept (of the equipment that is to be protected). The user must ensure that the devicewill properly recognize and manage (e. g.: switch off the Breaker) on the basis of userselected programming and settings all operational conditions (failures). Before startingany operation and after any modification of the programming/settings, make adocumented proof that the programming and settings meet the requirements of theprotection concept.

The Self-Supervision Contact (Life-Contact) has to be wired with the substationautomation system in order to supervise and monitor the state of health of theprogrammable protective device. It is very important that an alarm annunciation is drivenfrom the programmable protective device self-supervision contact (Life-Contact) thatrequires immediate attention when tripped. The alarm indicates that the protectivedevice is no longer protecting the circuit and the system should be serviced.

Typical applications for this product family/device line are for example:

• Feeder protection;• Mains protection;• Busbar protection;• Generator protection;• Transformer protection and• Machine protection.

This device is not designed for any usage beyond these applications. This applies also tothe use as a partly completed machinery. The manufacturer cannot be held liable for anyresulting damage. The user alone bears the risk if this device is used for any applicationfor which it was not designed. As to the appropriate use of the device: the technical dataspecified by Eaton has to be met.

1.1.2 Symbols and Definitions

Load Reference Arrow System

• It is common practice to either use the “Load Reference Arrow System” for loads(consumed energy) or the “Generator Reference System” for generators (generatedenergy).

• All E‑Series protection devices (except generator protection devices) use exclusivelythe “Load Reference Arrow System”. Generator protection devices are workingbased on the “Generator Reference System”.

• This applies to directions and phase angles. The phase angle is defined as the anglebetween the current phasor and the voltage phasor.

• Current and voltage arrows are to be counted positive in the direction of the arrow.

Typographical Conventions

• »Parameters are indicated by right and left double arrow heads and written in italic.«

• »SIGNALS are indicated by right and left double arrow heads and small caps.«

• [Paths are indicated by brackets.]

• Software and Device names are written in italic.

• Module and Instance (Element) names are displayed italic and underlined.

• »Pushbuttons, Modes, and Menu entries are indicated by right and left double arrowheads.«

Numbered Signals in Function Diagrams

The signals labeled by encircled numbers are meant to signify connections betweendifferent diagrams. So, if you find such an encircled number somewhere “on the left side”of a diagram you might want to look up in which other diagram this particular signal hasbeen generated.

Therefore all encircled numbers appearing “on the right side” (i. e. as an output signal) ofa diagram are listed as part of the Index chapter.



1.1.2.1 Symbols in Function Diagrams

Setting Values

The upper box in the diagram on the left is theusual symbol of a setting value in a functiondiagram. The setting name is specified by itsmodule and parameter name, separated by adot “.” one from the other.

Second example: Thanks to the high degree ofmodularisation in E‑Series protection devices,the logic depicted in some function diagrams isoften valid for several modules. In these cases,only a symbolic module name, for example:“Name”, is given. In the heading part of thediagram, the meaning of “Name” is specified asa list of modules to which the diagram applies.

In rare cases it is necessary to also specify themenu path (or at least the top-level menu item),because it would be too inconvenient to specifythis particular setting only based on modulename and parameter name. In the thirdexample, the setting »delta phi - Mode« ismarked as a Field Parameter (i. e. to be foundwithin menu branch [System Para]).

Another remark: All diagrams in this documentshow a small label, in this case: “HPT_Y05”. Thisis the diagram name, i. e. a unique identifier forthe diagram. Of course, this is not a settingname, nor any other part of the depicted logic.All function diagrams have an identifier with thecharacters “_E”.)

Bottom row, left: Numbered input signal; right:numbered output signal: From the technicalpoint of view, there is no difference to “normal”(non-numbered) signals. But these signalsappear in several different diagrams, and thenumbering helps to identify and locate themacross the Technical Manual.

Therefore all encircled numbers appearing “onthe right side” (i. e. as an output signal) of adiagram are listed as part of the Index chapter,so that you can look up where a particular signalhas beeen “generated”.

If the setting value of parameter »Name . VXSelection« is set to “Measured”, then output 1 isactive and output 2 is inactive.

If the setting value of parameter »Name . VXSelection« is set to “Calculated”, then output 1 isinactive and output 2 is active.

The setting value of parameter »Name .ExBlo1« is not a choice from a simple, fixedselection list, but it is another parameter(usually a binary output signal) that is assignedfrom a parameter list.

This means that the setting parameter assumesthe value of the assigned parameter. In case of abinary output signal, for example, it means thatthe parameter »Name . ExBlo1« is activewhenever the assigned output signal is active.

If no signal has been assigned then the output isalways inactive (and only the “No assignment”box, which is not connected in this example,would be active).

1.3 Modules, Settings, Signals and ValuesThe EBR-3000 is a digital protection device that holds various data in its internal memory.Some data is meant to be changed by the user to adapt the functionality to therespective application, other data types are set by the device during run-time and aretherefore read-only from the user's perspective.

All settings, device planning and checking the state of signals at run-time can be done:

• Directly at the device; or

• By way of the PowerPort-E software application.

Modules

The firmware of the EBR-3000 can be thought of being sub-divided in severalindependent function blocks. Throughout our Technical Documentation, we are talking of“modules” (or sometimes of “functions”). Every protection function, for example, is amodule of its own. For E‑Series devices, this is a fundamental concept: For example, thefunctionality of calculating statistical data is a module (named »Statistics«), everycommunication protocol is a module, the general functionality of controlling switchgeardevices is a module (named »Ctrl«), there is even a general protection module(named »Prot«) that interacts with all specific protection modules.

It is important to know that every parameter and every signal and value is always part ofexactly one module (even if the module name might not be displayed on the panel for thesake of simplicity).

Modules can interact with each other, either because this is a fixed implemented part ofthe firmware, or if the user has assigned some signal of a module to a parameter (thatbecomes a module input this way). An example for a fixed implemented interaction isthat the trip signal of any protection module always triggers the trip signal of thegeneral »Prot« module.

Some modules exist in several (identical) instances, which can be activated andconfigured independently. These can be used to have several protection stages. However,there is one fundamental difference to the EBR-3000: The functionality of all instances (ofa particular module) is always identical (except for the differences that are due todifferent setting values).

There is the following naming convention: If several instances of amodule »Module« exist, then these are named »Module[1]«, »Module[2]«, … (or, as ashort form for descriptions: »Module[x]«).

Types of Settings, Signals and Values

Settings (also called parameters)

• Parameters are data that can be modified by the user, to adapt the functionality ofthe respective application.

PowerPort-E users can save all settings to a file. This is a file with a filename of theform *.ErPara. It can be (re-)loaded at any later time, and the setting values


1 EBR‑3000 High Impedance Differential Protection Relay1.3 Modules, Settings, Signals and Values

contained therein can be transferred to some (other) EBR-3000 protection device.(For details see the PowerPort-E manual.)

(Remark: There are a few exceptions, where a particular setting is always storedwithin the device and never saved to a *.ErPara file. This is the case if it is notdesirable to directly transfer the setting value from one device to another; the TCP/IPsettings are an example for this.)

There are several types of parameters, depending on the type of data they can hold.For the user, it is not necessary to know details, but it can be good to know thatthere are numerical parameters (e. g. overcurrent thresholds) and parameters whichhold one option out of a selection list. These select options can either be fixed values(e. g. the choice of communication protocol), or they can be a signal (so that duringrun-time, the actual parameter value equals the state of the assigned signal). Thiscase of a signal assignment is what has been mentioned above as a “module input”.

• Some parameter properties depend on the value of particular other parameters. Forexample, the “device planning” parameters (in the [Device Planning] menu) do notonly activate or deactivate protection functions but also control the visibility of theirrelated parameters.

Some parameters depend on others not only with respect to visibility, but alsodefault values and/or available value ranges. (For example, the range of someprotection parameters depend on the CT ratio.)

• There are parameters that exist only once, named “Global Parameters”.

These are usually within the [Global Prot Para] menu.

• Setting Group Parameters can be found in menu branches [Set 1] … [Set 4]: Theseare protection parameters that have a “four-fold” existence: The user can set fourvalues, and each of these is member of a particular “parameter set” (Set 1 to Set 4).At any time only one of these four parameter sets is active, which has the effect thatthe respective set value is active. (This is always independent of the protectionfunction: It always affects all protection functions at the same time if one switches toanother parameter set.)

• By means of Adaptive Parameter Sets you can modify single parameters dynamicallyduring run-time: Setting values are defined to be dependent on the “True/False”value of a particular Boolean signal. It is possible to define up to four Boolean signalsfor value switching, which means that – together with the base value – such anAdaptive Parameter can have up to five alternative values (per parameter set, whichmakes a total sum of up to 20 values). Which one gets actively used at a particularmoment of time, will then depend on the run-time value of the (up to four) relatedBoolean parameters.

In contrast to Setting Group Parameters, Adaptive Parameter Sets are “local”, i. e.they are effective only within the protection function where they had been activated.

Note, however, that not all protection functions support Adaptive Parameter Sets.

Since some users are maybe not quite familiar with the concept of AdaptiveParameter Sets there is a dedicated chapter with a more detailed description. See╚═▷ “1.3.2 Adaptive Parameter Sets”.

Direct Commands



• Direct Commands are part of the “menu tree”, just like a setting parameter, butthey are meant to be executed immediately. Typical examples are the DirectCommands for resetting a Counter.

Therefore Direct Commands are NOT part of a *.ErPara parameter file.

Signals

• Signals are run-time states, i. e. depend on the result of a protection function or onthe state of a Digital Input.

Signals are part of the “menu tree”. They can all be found in the menu path[Operation / Status Display].

• Some Signals represent the state of the installation/equipment (e. g.: positionindicators of the breaker).

• Some Signals are assessments of the state of the grid and the equipment (e. g.:System OK, Transformer failure detected).

• Some Signals represent decisions that are taken by the device (e. g.: Trip Command)based on the parameter settings.

• Many signals can be assigned to particular parameters. This means the function ofthis parameter depends on the run-time state of the signal. For example, everyprotection function features several blocking parameters. (See also ╚═▷ “4.1.1Blockings”.) If a signal has been assigned to a blocking parameter then therespective protection function gets blocked as soon as the run-time state of theassigned signal becomes “True”.

• In the same way can signals also be assigned to the LEDs of the EBR-3000, so thatan LED is lit as soon as the assigned signal becomes “True”. (See also ╚═▷ “2.5.1LEDs”.)

Input States (for a module input)

• Input States are special signals and are part of the “menu tree”. For everyparameter to which a signal can be assigned, there is a related Input State. At run-time, the Input State reflects the current state of the assigned signal. This way thedependencies in the behavior of a protection function can be traced.

There is the following naming convention: If a parameter to which a signal can beassigned is named »Name«, then the related Input State has the name »Name-I«.

Counters, Values

• Values are more or less volatile data that are constantly kept up to date during run-time.

• The most common (and most important) type of Values is the set of MeasuredValues (e. g. the current and/or voltage values measured at the CT/VT, frequencyvalues); we are going to use the term Measured Values also for values that arederived from measured values by calculation, e. g. the power value calculated fromcurrent and voltage). Of course, the set of available Measured Values depends onthe capabilities of the particular protection device.



A Statistical Value is a special type of “calculated measured values”, and can be amaximum, minimum or average value; this helps to analyse the development of ameasured value in time. For most Statistical Values, there is a related DirectCommand, which can be used to reset the statistics.

• Another important type is the Counters. Whereas Measured Values are usuallyfloating-point numbers (mostly with a related unit of measurement), do Countershold a digital, integer number. For most Counters, there is a related DirectCommand, which can be used to reset the Counter value to 0.



1.3.1 Parameter Settings

Parameter Setting at the HMI

Every parameter belongs to an access area. Editing and changing of a parameter requiresa sufficient access authorization. See ╚═▷ “1.4.1 Access Authorizations (access areas)”for a details description of access areas.

The user can obtain the required access authorizations by unlocking access areas inadvance of parameter changes or context-dependent. In the following sections bothoptions will be explained.

Option 1: Direct Authorization for an Access Area

Call up menu [Device Para / Security / Access Level].

Select the required access level respectively navigate to the required accessauthorization (level). Enter the required password. If the correct password has beenentered, the required access authorization will be obtained. In order to do the parameterchanges please proceed as follows:

• Move to the parameter you want to change by using the Softkeys. If the parameteris selected, the lower right corner of the display should show a »Wrench« symbol.

This symbol indicates, that the parameter is unlocked and can be edited, because therequired access authorization is available. Confirm the Softkey »Wrench«, in order to editthe parameter. Change the parameter.

Now you can:

• save the change you made and have them adopted by the system or:

• change additional parameters and save finally all the altered parameters and havethem adopted by the system.

To save parameter changes immediately,

• press the »OK« key for saving changed parameters directly and to have themadopted by the device. Confirm the parameter changes by pressingthe »Yes« Softkey or dismiss by pressing »No«.

To change additional parameters and save afterwards,

• move to other parameters and change them



NOTICE!

A star symbol in front of the changed parameters indicates that the modifications haveonly been saved temporarily, they are not yet finally stored and adopted by the device.

In order to make things easier to follow, especially where complex parameter changes areinvolved, on every superior/higher-ranking menu level the intended change of theparameter is indicated by the star symbol (star trace). This makes it possible to control orfollow up from the main menu level at any time where parameter changes have beenmade and have not been saved finally.

In addition to the star trace to the temporary saved parameter changes, a generalparameter changing symbol is faded-in at the left corner of the display, and so it ispossible from each point of the menu tree to see that there are parameter changes stillnot adopted by the device.

Press the »OK« key to initiate the final storage of all parameter changes. Confirm theparameter changes by pressing the »Yes« softkey or dismiss by pressing Softkey »No«.

NOTICE!

If the display shows a Key Symbol instead of a Wrench-Symbol, this will indicate,that the required access authorization is not available.

In order to edit this parameter, a password is required, that provides the requiredauthorization.

NOTICE!

Plausibility check: In order to prevent obvious wrong settings the device monitorsconstantly all temporary saved parameter changes. If the device detects animplausibility, this is indicated by a question mark in front of the respective parameter.

In order to make things easier to follow up, especially where complex parameter changesare involved, on every superior/higher-ranking menu level, above the temporarily savedparameters an invalidity is indicated by the question mark (plausibility trace). This makesit possible to control or follow from the main menu level at any time where implausibilitiesare intended to be saved.

In addition to the question mark trace to the temporary saved implausible parameterchanges a general implausibility symbol/question mark is faded-in at the left corner of thedisplay, and so it is possible to see from each point of the menu tree that implausibilitieshave been detected by the device.

A star/parameter change indication is always overwritten by the question mark/implausibility symbol.

If a device detects an implausibility, it rejects saving and adopting of the parameters.



Option 2: Context-dependent Access Authorization

Navigate to the parameter, that is to be changed. If the parameter is selected, the lowerright corner of the display shows a »Key«-Symbol.

This symbol indicates, that the device is still within the »Read Only Lv0«-Level, or that thecurrent level does not provide sufficient access rights to allow editing of this parameter.

Press this Softkey and enter the password that provides access to this parameter. (Thispage provides also information, which password/access authorization is required to dochanges on this parameter.)

Please change the parameter settings.

Now you can:

• save the change you made and have them adopted by the system or:

• change additional parameters and save finally all the altered parameters and havethem adopted by the system.

To save parameter changes immediately,

• press the »OK« key for saving changed parameters directly and to have themadopted by the device. Confirm the parameter changes by pressingthe »Yes« Softkey or dismiss by pressing »No«.

To change additional parameters and save afterwards,

• move to other parameters and change them

NOTICE!

A star symbol in front of the changed parameters indicates that the modifications haveonly been saved temporary, they are not yet finally stored and adopted by the device.

In order to make things easier to follow up, especially where complex parameter changesare involved, on every superior/higher-ranking menu level the intended change of theparameter is indicated by the star symbol (star trace). This makes it possible to control orfollow from the main menu level at any time where parameter changes have been madeand have not been saved finally.

In addition to the star trace to the temporary saved parameter ch
