Introduction2.1.REX 521 protection relayThe protection relay REX 521 is designed for protection, control, measuring andsupervision in medium voltage networks. Typical applications include incoming andoutgoing feeders as well as substation protection. The protection relay is providedwith energizing inputs for conventional current and voltage transformers. Also ahardware version with inputs for current and voltage sensors is available.The protection relay is based on a multiprocessor environment. The HMI includingan LCD (liquid chrystal display) with different views makes the local use easy andinforms the user via indication messages. Modern technology is applied both inhardware and software solutions.The REX 521 is part of the substation automation concept for distributionautomation and extends the functionality and flexibility of the concept.81MRS 751107-MUM Protection RelayOperator’s Manual REX 52193.

Thenselect the desired language with [↓] and [↑] buttons.3.Confirm the selection by pressing the [E] button once more or cancel theselection by pressing the [C] button.After altering the language, the display menus are shown in the new language andthe selection is restored after a disconnection of the power supply.12Operator’s Manual3.1.3.PasswordsFig. 3.1.3.-1Password menusSetting values are protected by passwords. There are two different passwords, onefor protecting the HMI setting values and another for protecting settings throughserial communication.•The default value of the serial communication password is 001 and of the HMIpassword 999.•The HMI password is not active until it has been changed from the default value.After changing it, the relay prompts for password whenever the [E] button ispressed in the setting value menu. Once the right password has been given, itstays active until the display is returned to idle state by time-out. To disable theHMI password, change it back to the default value 999.•In case a password is forgotten, the HMI password can be viewed and changedvia serial communication.3.1.4.Display backlightThe backlight of the display is normally off. When a button on the HMI is pressed,the backlight turns on automatically and the panel is ready for further operations.•At power up, the backlight is also turned on during the display test.•After a time-out period (5 min), the backlight is automatically switched off ifthere has not been any activity on the panel.•When changing between Local/Remote mode by a digital input, the backlight isturned on for 10 seconds.3.1.5.Display contrastThe display contrast is temperature compensated, which means that the contrastautomatically adjusts itself with temperature to preserve readability.•To obtain optimal readability, the contrast of the display can be adjusted.Pressing simultaneously the [E] button and [↑] or [↓] button increases ordecreases the contrast.13Fig. 3.1.5.-1Adjusting display contrast•The display contrast may be adjusted anywhere in the menu structure except inthe setting menus where the [E] button is used for entering the setting mode.•The selected contrast value is stored in a non-volatile memory and thus, after anauxiliary power failure, the contrast is restored automatically.3.1.6.Display testUpon auxiliary voltage connection, the backlight is turned on and a short display testis run. This display test includes all the LEDs and the LCD. The LEDs are tested byturning them on simultaneously while the LCD shows two patterns so that all thepixels are activated. After the test, the display returns to normal state.•The display test can also be started manually by navigating toConfiguration\Display\Test display and then selectingTest display (refer to section “Menu chart” on page15).3.1.7.Selecting primary valuesThe setting values, input data and recorded values that are relative to some quantitycan be obtained directly in amperes and volts. For the relay to know how to convertbetween primary and per unit values, the setting values describing the measurementdevices (CT, VT, VD, RS) need to be properly set.1.Navigate to Configuration\Display\Primary values and selectPrimary values instead of the default Per unit values.2.Navigate to Configuration\Meas. devices and enter the data for allthe CTs and VTs, VDs and RSs that are in use in that particular hardware. Forinformation about setting the rated values for the protected unit and about thetechnical data of the measuring devices, refer to Technical Reference Manual,General (see “Related documents” on page6).3.1.8.Optically isolated serial communication portThe front panel of the protection relay is provided with an optical serialcommunication connector. The connector is used for programming the relay with aPC via a RS-232 cable, type 1MKC950001-1.143.2.Menu chartThe contents of the menu chart depend on the configuration of the relay. However,Fig. 3.2.-1An example of a menu chart structure15Operator’s Manual3.2.1.Measurement menuThe contents of the measurement menu depend on the relay configuration.If a measurement view is selected, it remains active after the time-out period. Thesame is true with the manual control view. From other views, the display reverts toidle mode at the same time as the backlight is switched off.•If energy measurements are present, accumulated values can be reset by pressingthe [C] button for 2 s.Table 3.2.1-1Measurement view16Table 3.2.1-1Measurement view (Continued)* The calculated thermal level of the device, maximum from the stator and the rotor.**Only available in configuration H083.2.2.Event menuThe event menu (Main menu\Measured values\Events) contains thefunction block name and the event in the same manner as the indication messages(see “Indication messages” on page22). The first view of the event menu shows theamount of events (maximum 50). The most recent event is stored on top of the list.When a certain event is selected, date and time of the event in question can be readby moving one step right with the [→ ] button. If the event in question is a trip eventand its data in the recorded data menu (Main menu\Protection\…\Recorded data1\…3\) has not been overwritten, it is possible to move directlyto the associated recorded data by moving right [→ ] again in the date and time view.Return to the event view with the [C] button or with the [← ] button, like in normalmenu navigation. When viewing recorded data, the return is directed to the eventsummary view (Main menu\Measured values\Events) if•the recorded data is overwritten, or•the original event is overwritten in the event list, or•the event list is cleared.These events are stored in the non-volatile memory, which means that they can alsebe seen after a disconnection of the power supply. When displayed, the event list canbe cleared by pressing the [C] button for 2 seconds.17Fig. 3.2.2.-1Event view3.2.3.Manual control3.2.3.1.Local/Remote position selectionThe control position can be changed in Control\Manual control\Local/Remote.•The control mode can be selected by pressing the [E] button and using the [↑] and[↓] buttons.•The [E] button confirms the selected mode and the [C] button cancels theselection and keeps the current mode.For password handling, refer to section “Passwords” on page13.Table 3.2.3.1-1Control positionsControl position DescriptionControl off Local and remote operations are inhibited. The current state of the objectis shown in the control menu.Local Object can be controlled from the HMI and the digital inputs. Remotecontrol is inhibited.Remote Object can be controlled via remote communication. Control from theHMI and digital inputs is inhibited and the object state is shown in thecontrol menu.External input The digital input programmed for selector Local/Remote is used forselecting between the local and remote modes. When selected the modewill be displayed as Local (ext.) or Remote (ext.) depending onthe digital input state.The selected control position remains the same during auxiliary power-off.When the local mode is selected, the character “L” is shown in the bottom-rightcorner of the HMI main view. However, if the language in the relay is other thanEnglish, the character that is shown in the display depends on the selected language. 183.2.3.2.Controlling breakerThe object control menu is in Control\Manual control\Control CB.Only the current position of the breaker is shown and no control is possible in remoteor control off mode. In local mode the state of the breaker is shown and the possibletarget states can be scrolled with [→ ] and [← ] buttons. Possible target states areopen and closed. When the desired target state is selected the object can be selectedby using the [E] button.Message =Preparing... can be briefly shown before the text=Are you sure? is displayed. The operation can then be confirmed with the [E]button and cancelled with the [C] button. If the operation is cancelled the text=Aborted is displayed for three seconds and then the current state of the breakeris shown. The same happens if the =Are you sure? has been displayed for 30seconds.Notice that an adjustable timeout in Control\General\Select timeoutrestricts the time between the object selection and the control request. If the timeoutis shorter than 30 seconds and it elapses before the operation is confirmed,controlling the object will not be possible before the object is selected again. If theoperation is confirmed, the appropriate transition text (=Opening... or=Closing...) is shown for at least four seconds after which the current state ofthe object is shown.19The current state of the interlocking of the object can prevent the select or executerequests. In that case the text =Interlocked is displayed for three seconds. Theattempted operation is cancelled and after the three seconds the current state of theC o n t r o l C B=O p e n.

To enter the valid password, change the active digit by pressing the buttons [← ] and [→ ], then set the digit value by pressing the buttons [↑] and [↓].4.Once the password has been entered, press the [E] button to confirm. Now the selected setting value starts flashing.5.Enter the new setting value using the buttons [↑], [↓] and [→ ], [←].6.Press the [E] button to confirm.7.If the new value is within the allowed limits, it is now stored in the non-volatile memory and restored after disconnection of power supply.8.If an illegal setting value is confirmed, a message in the display tells the user that the setting is out of range by showing the message Invalid value, and the previous parameter value remains unchanged.3.2.5.Setting bit masksEvent masks and switchgroups are presented as bit masks with a checksum. Most of the events can be included in or excluded from the event reporting by altering the bits of the event masks. Switchgroups are used for changing the connections of inputs and outputs to the relay function blocks.Fig. 3.2.5.-1Bit mask in setting modeWhen navigating in menus containing bit masks, only the checksum is shown. If setting mode is entered, the single bit presentation (bit 0, value 1, in the example above) appears in the rightmost lower corner of the display. The contents of the bit mask may be altered by entering single bit values. However, the new values are not valid until setting mode has been exited by pressing the [E] button.1.Navigate to the right parameter using the buttons [↑], [↓] and [→], [← ] and the menu chart structure as reference.2.Activate setting mode by pressing the [E] button.3.If the default HMI password has been changed, it is now prompted. To enter the valid password, change the active digit by pressing the buttons [← ] and [→ ], then set the digit value by pressing the buttons [↑] and [↓].4.Once the password has been entered, press the [E] button to confirm. Now the selected setting value starts flashing.5.Enter the new setting value using the buttons [↑], [↓] and [→ ], [← ].6.Press the [E] button to confirm.When entering single bit values, the bit to be edited may be shifted by pressing the[→ ] button when the cursor is located in the rightmost corner of the display. In thatway, the cursor does not have to be moved back and forth between the bit numberand the value during the setting period, thus simplifying the procedure.For information about the meaning of each event, refer to Event List for REX 521on the CD-ROM Technical Descriptions of Functions (see “Related documents” onpage6).3.3.Indication messagesThere are two different kinds of indication messages:•A text message together with a LED indication.This type of messages are related to information from the protection functionsand information concerning the condition of the protection relay (self-supervision).•A text message without a LED indication.This type of messages are related to condition monitoring, alarms and warningsor help texts appearing when certain display operations are performed.Indication messages have a certain priority. If different types of indications occursimultaneously, the message with the highest priority appears on the display.Priority order of the messages:1.Internal fault, CBFP2.Trip3.Start, Block4.Help messagesIndication messages may be cleared with the [C] button, until the display reverts tothe menu active before the events.Help messages are displayed when certain operations are done. For example, whenresetting output relays, events and registered values by pressing the [C] and [E]buttons for 5 s, a help text describing the operation is displayed at the same time.3.3.1.Protection indicationsWhen a protection function starts, the symbol of the protection function and the textSTART are displayed. The corresponding yellow LED indicator is also lit. In caseof three-phase or two-phase protection functions, the faulted phases are displayed aswell.Fig. 3.3.1.-1Indication of startIf a started protection function is blocked, the name of the function and the textBLOCK are displayed. Now, the yellow LED indicator is blinking.22Fig. 3.3.1.-2Indication of blockingIf a protection function trips, the name of the function and the text TRIP appear onthe display. The red LED indicator is lit. The faulted phases are displayed in thiscase.Should the protection function deliver a delayed trip for circuit-breaker failureprotection (CBFP), the red indicator starts blinking.Fig. 3.3.1.-3Indication of trip3.3.2.Self-supervisionThe protection relay is provided with an extensive self-supervision system. The self-supervision system handles run-time fault situations and informs the user aboutexisting faults over the display and the serial communication.When a fault has been detected, the green READY indicator starts blinking. At thesame time, the self-supervision (IRF) output relay is activated.Additionally, a fault indication text INTERNAL FAULT appears on the display andan event is generated.Fig. 3.3.2.-1Indication of faultThe fault indication has the highest priority and no other indication can overrun it.The fault indication text is displayed until it is cleared by pressing the [C] button.The green READY indicator continues blinking as long as the fault is present.Should the fault disappear after a reset, the indicator stops blinking and an event isgenerated over the serial communication. The self-supervision (IRF) output relay isreturned to its normal state.23243.3.3.Condition monitoring indicationIf the relay configuration includes condition monitoring functions that are not directly related to any protection function or to the internal relay condition,indication messages with the message SUPERV and an explanatory text appear if faults are found.Fig. 3.3.3.-1Condition monitoring indicationOperator’s Manual3.4.LED indicators3.4.1.Green indication LED (READY)3.4.2.Yellow indication LED (START)3.4.3.Red indication LED (TRIP)253.5.Alarm LEDs3.5.1.Alarm LED 1-8a.Valid only if the LED is not activated by the parameter Alarm LED States.b.The alarm can also be OFF if an auxiliary supply break has occurred. The state of the LED is thenpreserved and has to be acknowledged (cleared) from the main view.26274. Test modeDigital inputs, output relays and IRF relay may be tested by setting the parameter Test mode to Testing in the menu Main menu\Tests\General . When test mode is activated, the green READY indicator is blinking. For more information, refer to Technical Reference Manual, General (see “Related documents” on page 6).Test mode can be cancelled by setting the parameter to No test or by disconnecting the power supply.If the user does not cancel the test mode, it remains active and the Ready LED remains blinking.4.1.I/O test The picture below shows the menu used for digital input testing (Tests\Inputs ) in the hardware variant with nine digital inputs. The digits correspond to the inputs DI1...DI9, starting from the right side. Fig. 4.1.-1Digital input testing The following picture shows the menu used for output relay testing Tests\Outputs . Observe that the self-supervision relay is activated in another menu and is thus not included in this menu. The relays are activated in the order: SO, PO and HSPO, starting from the right side.Fig. 4.1.-2Output relay testing If the user forgets to cancel the test mode, it remains on and the Ready LED indicator remains flashing.4.2.IRF testThe IRF relay may be tested by activating the IRF relay in the menuMain menu\Tests\General\Activate IRF .4.3.Function block testThe outputs (Start and Trip) of a function block can be activated locally via the HMIor externally via serial communication. This is possible without setting the relay intest mode as described in “Test mode” on page27. The outputs are activated byusing control parameters of the function. For more information about the functions,refer to the CD-ROM Technical Descriptions of Functions (see “Related documents”on page6).285.

Panel cut-out dimensionsThere are two options to widen the existing cut-out: To the left or to the right depending of the switchgear lay-out(free space on it).Figure 2: Left cutting Figure 3: Right cuttingFigure 1: REX521RRP with REF615 replacement relayA. 179 mm ± 1, new cut-out widthB. 136 mm ± 1, old cut-out widthC. 254 mm ± 1Cu t t i n g To o l O p e r at ing G ui d e 53. Cutting orderFigure 4 illustrates the cutting order on the front side of the switchgear door when the cutout is widened to the right.The left side cutting is symmetrical but to the left.Ensure the needed free space before starting the cutting procedure.If offcut gatherer is not used, protect the personnel and the switchgear panel from flying offcuts.It is recommended to use the gatherer. Figure 4 illus-trates the needed free space when the gatherer is in use. If there is not enough free space for the gatherer (see Figure 5 and Figure 6), the cutting head can be usedwithout the gatherer. However, safety concerns must be addressed. As the cutoffs may fly from the cutting head, make sure to pick up all the cutoffs and clean dust after the work is completed.Figure 4: Cutting order on the front side of the switchgear doorFigure 5: Cutting order to the leftFigure 6: Cutting order to the rightA. 179 mm, new cut-out widthB. 8 mmC. 254 mmD. 136 mm, old cut-out widthE. 58 mmF. 18 mmG. 100 mm1.

Add the gatherer (9) to the die (6) part of the cut-ting head with M6 socket screws (10).Use tightening torque of 4.2...5.2 Nm.The cutting tool kit includes a socket screw key (ISO2936-5) for the M6 screws.10Cu t t i n g To o l O p e r at ing G ui d e 9. Check and correct the gatherer alignment with the cutting head.Ready installed cutting head with the gatherer. After assembling the cutting head, insert the bat-tery to the power unit. The battery can be insertedfrom either side.Cu t t i n g To o l O p e r at ing G ui d e 116. PreparationsSee the Safety Guide before using the cutting tool.The cutting can be performed from the front or the back of the panel door. It is recommended to make the cut-out from the front side of the door panel to avoid sharp edges and ensuring smooth installation of the new replacement relay.The instructions in this document are based on making the cut-out from the front. The low-voltage compartment must be de-energized during the hole cutting procedure and installation of the new replacement relay.Ensure that there is enough space to operate the cutting tool in all intended directions. Check the space required by the new replacement relay. The cutting tool operation needs space around the cut-out.1. Remove the existing device.2. Release the signal connectors (not their wires).3. Release the wires from current/voltage connector.The used current/voltage connector wires arereused (in specified connector poles) with the newreplacing device.12 Cu t t i n g To o l O p e r at ing G ui d e6. Release the four fixing brackets.4. Release the protective ground wire.5. After the wires have been released, the whole de-vice can be released. Remove the four fixing bracketscrews.Cu t t i n g To o l O p e r at ing G ui d e 137. Operating the cutting tool on the left/right side edges1. Widen the existing cut-out to the left or to the right depending on the switchgear layout (freespace).For your safety, keep your hands on the powerunit, never on the cutting head.Beware of the sharp edges! Use safety gloves,protective glasses, hearing protectors and a hard hat.7. After releasing all the four fixing brackets, removethe device.2. Check that the cutting head is correctly installed. The marking REX 521 should be on the same side onthe punch and the die.14 Cu t t i n g To o l O p e r at ing G ui d e4. Push the operating switch as long as the sheetmetal part has been cut off.Be careful with the flinging offcuts, especiallyif the offcut gatherer is not used.Do not push the operating switch too long as it may cause maximum pressure in the power unit and result in additional force with vent lever use.3. Start the cutting procedure by pushing the guiding faces of the cutting head to the cut-out edges: to the top edge and to the right edgeside if the right edge widening/cutting is valid.For your safety, keep your hands on the powerunit, never on the cutting head.Beware of the sharp edges!5. Push the vent lever to ensure that the punch isreleased after each cut.In some cases, additional force is needed topush the vent lever.6. Make five cuts 1...5/6...10 one below the other (seefigure 4).Shake the cutting tool in between the cuttings 1...10 to arrange more space for the offcuts inside the gatherer.It is recommended to make overlapping cuts of 1...3 mm to avoid sharp edges in between the cuttingjunction points.Cu t t i n g To o l O p e r at ing G ui d e 15The fourth cut.7. For the fifth cut, push the cutting head, which is guiding the faces, firmly against the bottom sideedge.16 Cu t t i n g To o l O p e r at ing G ui d e2. Use a file to remove any sharp edges or burrs aroundthe cut-out area.3. Cover the relay compartment to avoid spreading dust.1. After each relay cut-out (ten separate cuttings), empty the offcut gatherer.For safety reasons remove the battery first.Ensure that no offcuts remain inside the switchgear if the offcut gatherer was not used.8. Finalizing the cutout4. Clean dust and any remaining offcuts.Cu t t i n g To o l O p e r at ing G ui d e 179. Finishing the work2. Push the new replacement relay firmly against the panel cut-out.1. It is advisable to coat bare surfaces, for example with cold galvanized compounds, in case of corrosive atmosphere.Install the new replacement relay.3. Add the four fixing brackets.4. Tighten all the four fixing bracket screws step bystep. Use tightening torque of 1.3...1.7 Nm.18 Cu t t i n g To o l O p e r at ing G ui d e5. Start the wiring work by connecting the safety ground wire.6. Connect the signal wire connectors. Fix female side wire connectors with their fixing screws to the male side connectors. Use a type PH 0 or PZ 0 (ISO 8764/2) screwdriver. Use tightening torque of 0.2Nm.8. Finish the work and close the door.7. Install the current and voltage wires. Only use screwdriver and insert bits for Phillips (PH 1) cross-recessed screws (M3.5). Use tightening torque of0.8...1.2 Nm.Cu t t i n g To o l O p e r at ing G ui d e 19—ABB Oy Distribution Solutions EP Service P.O.
