Self test DiagnosticStart Leave an initial condition or reset condition (Pickup)Trip Operation (with operate time)
Operating time Duration of time interval between the instant when the character-istic quantity in reset condition is changed, under specifi ed condi-tions, and the instant when the relay operates
Dropout ratio The ratio of a reset value to an operate value in well-specifi ed con-ditions. The dropout ratio may be lower or greater than 1 according as an over or under element is considered
Reset time Duration of the time interval between the instant when the charac-teristic quantity in operate condition is changed, under specifi ed conditions, and the instant when the relay operates.
The stated reset time is related to a step variation of characteristic quantity in operate condition to the reset condition.
Overshoot time The critical impulse time for a relay which is in its reset condition, is the longest duration a specifi ed change in the input energizing quantity(ies) (characteristic quantity), which will cause the relay to change to operate condition, can be applied without the relay switches. The overshoot time is the difference from the operate time and the critical impulse time.
The declared values for the overshoot time are applicable with the lower setting value of the operation time.

2 G E N E R A L2 G E N E R A LPreface
The relay type NA011 can be used in radial networks as feeder or power transformer protection. In solidly grounded systems the residual overcurrent protection can be used on feeders of any length, while in ungrounded or Petersen coil and/or resistance grounded systems, the residual overcurrent protection can be used on feeders of small length in order to avoid unwanted trippings due to the capacitive current contribution of the feeder on external ground fault.Beside to the phase and residual overcurrent protections, the automatic reclosing function is pro-vided.The NA011 protection relay may be shipped with traditional CTs or low power (LPCT) current inputs; for both versions, the residual overcurrent protection can use the measured (CTs or balanced trans-former) or the calculated residual current.
Following input circuits are available:Phase current inputs
Traditional CTsThree phase current inputs with secondary nominal currents independently selectable at 1 A or 5 A through DIP-switches.
Low power CTsThree phase current inputs with primary nominal currents independently selectable through DIP-switches and software.
Residual current inputMeasured residual current
One residual current input with secondary nominal current selectable at 1 A or 5 A through DIP-switches.
Calculated residual currentResidual current is calculated by the vector sum of the three phase currents, measured by three 1 A or 5 A CTs or by three LPCT type sensors.
Setting, programming and reading operations must be effected by means of Personal Computer with ThySetter software or by means of remote communication interface (RS485 bus); all operations must be performed through MMI.
The NA011 hardware case is suitable for flash and rack mounting

Main featuresMetallic case. Backlight LCD 2x16 Display.Eight LEDs that may be joined with matrix criteria to many and various functions.RESET key to clear LED indications and latched output relays.Three binary inputs.Independently settable for start, trip, self-test and control four output relay (K1...K4) Each output relay may be set with normally energized or normally de-energized operating mode and manual or automatic reset (latched/no-latched).Rear RS485 port, with ModBus protocol.RS232 front serial port (local communication for Thysetter).Real time clock with super capacitor backup.
The most signifi cant constructive features are:Galvanically insulated input and output circuits (communication and binary circuits included).Fast sampling rate for inputs.Optimum fi ltering of input signals through combined use of analog and digital fi lters.Traditional electromechanical-type fi nal output contacts with continuous monitoring of control coil continuity.Auxiliary supply comprising a switching-type voltage stabilizing circuit having a very wide working range and a very small power dissipation
The most signifi cant operating features are:Programming of operating modes and parameters by means of the front keys and alphanumeric display, with a programming procedure based on carrying out guided selections and on explicit and immediate signalling of the operations being performed, so that such procedure can be carried out without coding tables or mnemonic informations.The feature modifi cation operations do not interrupt the normal functions of the relay.Impossibility of programming unacceptable parameter values, thanks to the automatic limitation of top and bottom scale values for the relative setting ranges.Currents are sampled 64 times per period and measured in the effective value (RMS) of the funda-mental component using the DFT (Discrete Fourier Transform) algorithm and digital fi lters.The fault recorder (SFR) runs continuously capturing in circular mode the last twenty events upon trigger of binary input/output and/or element pickup (start-trip).The event recorder (SER) runs continuously capturing in circular mode the last three hundred events upon trigger of binary input/output.Digital fault recorder (DFR) in COMTRADE format (oscillography).

4.2 SOFTWARE DESCRIPTION
The program which handles operation of the Pro-N relays is made up of three fundamental elements shown in the following block diagram.
KernelThe kernel represents the nucleus of the system: it includes the processing functions closest to the electronic circuits; particularly the algorithms providing for the generation of the synchronisms (tim-ers) for sampling the analogue signals and numerical processing. The software is structured with interrupts operating with various priority levels in a non “pre-emp-tive” task system. By means of Discrete Fourier Transform calculation, based on 64 samples/period, information is deduced in relation to the amplitude and phase of all the current measurements; these are constantly updated and at the disposal of all the protection and control application algorithms. In addition, the kernel manages a service communication protocol known as Basic Protocol (BP).
DriversThe driver library contains all the specialised modules for the command and control functions which make up the connection ring between the kernel and the application. Examples of drivers include the Modbus communication and LCD display modules.
ApplicationThe application contains all the elements which carry out the protection and control functions. The main modules are:
- diagnostic function,- input management (logical inputs and block signal), - protective functions, - event recording, - output management (output relays, LEDs and block signals).
Each element (Kernel, Drivers and Application) may, in turn, be split into modules:
Base protocol (kernel)The module known as the Basic Protocol (BP) manages the service communication between the kernel and the other modules through the communication buses:
- direct for internal functional call,- SPI over synchronous serial, - SCI over asynchronous serial. The activities which may be performed by means of BP include:
- measurement confi guration ,- measurement reading,- measurement enabling.
Calibration (kernel)Calibration is performed using the base protocol functions for coordinating the calibration and test-ing stages with the automatic testing equipment (ATE).
Communication (drivers)The protective device implements the MODBUS RTU protocol for communicating via the RS232 inter-face with the ThySetter setting software and via the RS485 interface with the fi eld bus. All major codes according to the Modbus standard are envisaged; for a complete description and map of the addresses, please refer to the appendix mentioned further in this manual.

23NA011- Manual - 10 - 2013FUNCTION CHARACTERISTICS
Data Base (application/drivers)Using modular criteria, the database is structured in three sections:
- RAM containing the volatile data, - REE and PAR containing the data recorded in non-volatile memory. Duplication of the data into two memory banks is envisaged with a continuous control system based on the cross checking of the consistency of the stored data. Modification of the calibration pa-rameters is split into two stages; in particular, data undergoing modification is placed in temporary memory and subsequently confirmed permanently (Store command) or discarded (Clear command). Instead, the area identified as REE is set aside for recording data which does not require the Store command for storage, or date written directly by the application (e.g.: counters,...)
Self-test (application)This function cyclically monitors the operation of the main hardware and software functions without affecting the process cycle with any signifi cant delays. In particular, the functions monitored are the following,
- the reference voltage levels,- output relay coil continuity, - the program fl ow control by monitoring the execution times and stack area occupancy,- checking the pilot wires (accelerated logic system), - the consistency of the data in the REE and PAR blocks, duplicated in the EEPROM.
Development toolsFor the development of the project, a CASE instrument has been developed, responsible for the opti-mized production of software code for the management of collaboration, the database and the MMI data and the Xml files used for communication. The automatic code generation criteria ensures the quality of the result in terms of the reusability, verifiability and maintainability of the software life cycle.

4.3 I/O DESCRIPTION
Metering inputsThe following input are provided:
Three phase current inputs for traditional CTs or LPCTs (Low Power Current Transformers).One residual current input available on NA011#xxx2 and NA011#xxx3 versions.The nominal currents are independently adjustable at 1 A or 5 A through DIP-switches (CTs inputs).
The input circuits are dimensioned in order to withstand the currents which arise when a fault oc-curs, both in transient and steady state condition.
Signal processingVarious processing levels are involved:
Acquisition (base level).Direct measures of physical channels (fi rst level).Calculated measures (second level).Derived (third level).
The measures concerning a level are based on data worked out in the previous level.For each level the required resources concerning the priority for tasks (conditioning circuits, DSP) are on hand.
ACQUISITION (base level)The input signals are sampled 24 times per power cycle
- iL1...iL3 phase currents instantaneous value- iE residual current instantaneous value
From the sampled quantities, several measures are computed for protection, monitoring and meter-ing purposes.
Samples are processed by means DFT (Discrete Fourier Transform) algorithm and the phase and amplitude of fundamental are computed:
Phase currents IL1, IL2, IL3
Residual current IE[1]
Note 1 The residual current input is available on NA011#xxx2 and NA011#xxx3 versions; when input is unavailable (NA011#xxx1 version), the residual current is calculated by the vector sum of the three phase currents, measured by three 1A or 5A CTs or by three LPCT type sensors.

Output relaysFour output relays are available (K1...K4) with two changeover contacts (SPDT, type C):[1]
K1, K2 and K4 are trip relays.K3 is a signalling relay.[2]
Each output relay may be programmed with following operating mode:Operation MODE (No latched, Latched).Logic (Energized/De-energized).
To each output relay a programmable timer is matched (Minimum pulse width parameter).All parameters are available inside the Set \ Relays menu.
Any change to the settings can be affected at any time, also with the relay on duty, separately for each relay.Notes:
When de-energized operating mode is set, the relay remains in rest condition if no trip command is in progress.When energized operating mode is set, the relay remains in operating condition if no trip command is in progress and the auxiliary supply is powered on.When no-latched operating mode is set (Kx Mode No-latched), the output relay reset at the end of the trip condition. To each output relay a programmable timer is matched (minimum pulse width operation).When latched operating mode is set Kx Mode Latched, the output relay doesn’t reset at the end of the trip condition; it stays ON until a reset command is issued (RESET key, ThySetter or com-munication command).It is advisable to make sure that the output contact technical data are suitable for load (Nominal current, breaking capacity, make current, switching voltage,...).
Matching every output relay to any protective element is freely programmable inside the Setpoints submenus according a tripping matrix structure.[3][4]

Phase overcurrent - 50/51Preface
Three operation thresholds, independently adjustable (I>, I>>, I>>>) with adjustable delay (t>, t>>, t>>>).The fi rst one may be programmed with inverse time according the IEC 60255-3/BS142 standard.The second and third thresholds have a defi nite time characteristic.For the defi nite time thresholds a reset time can be set (t>>RES, t>>>RES) useful to reduce the clearing time for intermittent faults.
Operation and settingsEach phase fundamental frequency current is compared with the setting value. Currents above the associated pickup value are detected and a start is issued. After expiry of the associated operate time a trip command is issued; if instead the current drops below the threshold, the element it is restored.The fi rst threshold (I>) may be programmed with defi nite or inverse time according the following characteristic curves:
Standard Inverse Time (IEC 255-3/BS142 type A or SIT): t = 0.14 · t>inv / [(I/I>inv)0.02 - 1]Very Inverse Time (IEC 255-3/BS142 type B or VIT): t = 13.5 · t>inv / [(I/I>inv) - 1]Extremely Inverse Time (IEC 255-3/BS142 type C or EIT): t = 80 · t>inv / [(I/I>inv)2 - 1] Moderately Inverse (ANSI/IEEE type MI): t = t>inv · {0.01 / [(I/I>inv)0.02 - 1] + 0.023}Very Inverse (ANSI/IEEE type VI): t = t>inv · {3.922 / [(I/I>inv)2 - 1] + 0.098}Extremely Inverse (ANSI/IEEE type EI): t = t>inv · {5.64 / [(I/I>inv)2 - 1] + 0.024}I-squared-t (I 2t = K): t = 16 · t>inv / (I/I>inv)2
Where:t: operate timeI>inv: threshold settingt>inv: operate time setting
For all inverse time characteristics, following data applies:Asymptotic reference value (minimum pickup value): 1.1 I>invMinimum operate time: 0.1 sRange where the equation is valid:[1] 1.1 ≤ I/I>inv ≤ 20
For all defi nite time elements the upper limit for measuring is 40 In for traditional CT input versions or 12.5 kA (primary current) for LPCT input versions (e.g. 25 In with In = 500 A).All overcurrent elements can be enabled or disabled by setting the relative start and/or trip output to a selectable relay inside the Set \ Relays menu.The fi rst overcurrent element can be programmed with inverse time characteristic by setting the I>Curve parameter (DEFINITE, IEC/BS A, IEC/BS B, IEC/BS C, ANSI/IEEE MI, ANSI/IEEE VI, ANSI/IEEE EI, I2T) available inside the Set \ 50/51 menu.An adjustable reset time delay is provided for second and third threshold (t>>RES, t>>>RES).
Note 1 When the input value is more than 20 times the set point , the operate time is limited to the value corresponding to 20 times the set point

Residual overcurrent - 50N/51NPreface
The residual current is:Measured for NA011#xxx2 and NA011#xxx3 versions from one residual current input with second-ary nominal current selectable at 1 A or 5 A through DIP-switches or,
Calculated for NA011#xxx0 and NA011#xxx1 versions by the vector sum of the three phase currents, measured by three 1A or 5A CTs or by three LPCT type sensors.Two operation thresholds, independently adjustable (IE>, IE>> with adjustable delay (tE>, tE>>) are available; they may be programmed with defi nite or inverse time according the IEC, ANSI/IEEE or I2T standard curves.
Operation and settingsThe residual fundamental frequency current) is compared with the setting value. Current above the associated pickup value is detected and a start is issued. After expiry of the associated operate time a trip command is issued; if instead the current drops below the threshold, the element it is restored.The thresholds (IE> and IE>>) may be programmed with defi nite or inverse time according the follow-ing characteristic curves:
Standard Inverse Time (IEC 255-3/BS142 type A or SIT): t = 0.14 · tE>inv / [(IE/IE>inv)0.02 - 1]Very Inverse Time (IEC 255-3/BS142 type B or VIT): t = 13.5 · tE>inv / [(IE/IE>inv) - 1]Extremely Inverse Time (IEC 255-3/BS142 type C or EIT): t = 80 · tE>inv / [(IE/IE>inv)2 - 1] Moderately Inverse (ANSI/IEEE type MI): t = tE>inv · {0.01 / [(IE/IE>inv)0.02 - 1] + 0.023}Very Inverse (ANSI/IEEE type VI): t = tE>inv · {3.922 / [(IE/IE>inv)2 - 1] + 0.098}Extremely Inverse (ANSI/IEEE type EI): t = tE>inv · {5.64 / [(IE/IE>inv)2 - 1] + 0.024}I-squared-t (I 2t = K): t = 16 · tE>inv / (IE/IE>inv)2
where:t: operate timeIE >: pickup valuetE >inv: operate time setting
For all inverse time characteristics, following data applies:Asymptotic reference value (minimum pickup value): 1.1 IE>Minimum operate time: 0.1 sRange where the equation is valid:[1] 1.1 ≤ IE/IE>inv ≤ 20 If IE>inv pickup ≥ 2.5 IEn, the upper limit is 10 IEn
For all defi nite time elements the upper limit for measuring is 10 IEn for version with CTs inputs and 35 In for version with LPCTs inputs.
All elements can be enabled or disabled by setting the relative start and/or trip output to a selectable relay inside the Set \ Relays menu.For each threshold a reset time can be set (tE>RES, tE>>RES) useful to reduce the clearing time for intermittent faults.
Note 1 When the input value is more than 20 times the set point , the operate time is limited to the value corresponding to 20 times the set point

Breaker failure - BFPreface
When the protection issues a trip command but, because an anomaly, the circuit breaker cannot open, the breaker failure protection issues a back-up trip command to trip adjacent circuit break-ers.The breaker failure function may be started by internal protective function if associated with BF.
Operation and settingsThe starting of the timer occurs if both the following conditions are fi lled:
Start and trip of internal protective elements (trip of elements matched with BF protection);The CB is closed (the CB state may be acquired by means one or two binary inputs connected to the auxiliary contacts 52a and 52b).
If both conditions are held along the set operate time tBF, the BF element trips at deadline, vice versa the timer is cleared and the function is restored.To the purpose to restore the BF element as quickly as possible, with start of the same protection (see A condition), additionally to the trip of some internal protections, their starts are required (start reset is faster than trip reset).
The element may be disabled or enabled by associating to the BF Enable parameter the Trip I>, trip I>>, trip I>>>, trip IE>, trip IE>> and/or Trip EXT parameter.
The tBF and BF Enable parameters are available inside the Set \ Breaker failure-BF menu.

Circuit breaker supervisionPreface
By means 52a and/or 52b auxiliary contacts, the CB position is acquired; based on this information a Open and/or Close can be sent safely issued by user.For detecting the CB position one or two binary input (52a or 52b) can be used.For detecting the CB wrong congruity two input (52a and 52b) must be used.To activate the Auto-reclose function the CB state acquisition must be enabled.
Operation and settings52a is the auxiliary contact in the breaker that is in the same position as the breaker (52a open = CB open). It must be assigned to the IN2 binary input.52b is the auxiliary contact in the breaker that is in the opposite position as the breaker (52b open = CB closed)). It must be assigned to the IN1 binary input.
Circuit breaker commandsBy means of the (Open) and (Close) keys the circuit breaker command may be issued.The committed output relays must be enabled inside the Set \ Relays menu.

4242 NA011- Manual - 10 - 2013 FUNCTION CHARACTERISTICS
Rapid reclosure dead time (trdt)[1]
It is the time interval from the CB opening command and the CB reclosing command.The setting time for the rapid reclosure is a compromise from the time required for the arc extinc-tion on the fault location and the max allowable out of service time of the line.The parameter must be adjusted on the basis of the extension and grid voltage. The minimum value should allow the arc deionization and the insulation restoring in order to comply with the mechani-cal characteristics of the circuit breaker and the residual arc extinction.
Slow reclosure dead time (tsdt)[2]
It is the time interval from the failed fast reclosure and the start of slow reclosure sequence.The setting time for the waiting time is a function of the mechanical characteristics of the circuit breaker (data must be supplied by manufacturer). For newest circuit breakers typical values are 60 s and 180 s for oldest circuit breakers.
Reclaim time (tr)It is the time interval following the initiation of reclosure command.If no trip operation arises within the reclaim time the reclosing operation is regarded as successful and the device is ready for a new sequence.If any trip arises within the reclaim time the cycle goes on with sequence depending from the setting mode.
Slow reclosure fault discrimination time (td).If any trip arises within the time interval td, the cycle goes off and the failed reclosure is issued.
Rapid reclosingWith Rapid-reclose setting (79 Mode = Rapid), if no faults (CB opening command) occurs within the reclaim time (Successful rapid reclosure), after the reclaim time the system comes back to reset; a new trip starts a rapid reclosing sequence again. Any trip within the tr time interval causes a block-ing of the sequence and a failed reclosure signal is issued (unsuccessful rapid reclosure);
Unsuccessful rapid reclosure; new fault (CB opening command) occurs within the reclaim time.The automatic reclosing system is blocked and a failed reclosure command is issued.After the reclaim time, following a closed CB condition without any faults, the system comes back to reset.
Note 1 The reclosing waiting time is calculated from the fi rst event that is detected between the reset of the trip element and the open state acquisition of the circuit breaker
Note 2 The reclosing waiting time is calculated from the fi rst event that is detected between the reset of the trip element and the open state acquisition of the circuit breaker

Rapid +Slow reclosingWith Rapid+Slow reclose setting (79 Mode = Rapid+Slow) if a fault (CB opening command) oc-curs within the reclaim time, after the slow reclosure dead time (tsdt) a slow reclosure is operated. Because no trip occurs within the reclaim time the system comes back to reset; any new trip starts a rapid + slow reclosing sequence again (Successful rapid + slow reclosure).
Conversely if a new fault (CB opening command) occurs within the reclaim time and the next slow reclosure is issued with fault within the slow reclosure fault discrimination time td the automatic reclosing system is blocked and a failed reclosure command is issued (unsuccessful rapid + slow reclosure).
Rapid + slow reclosures and subsequent delayed reclosures
With Rapid+Slow reclose setting (79 Mode = Rapid+Slow) and more than zero reclosures are enabled (79N.DAR = 1...5) if a fault (CB opening command) occurs within the reclaim time, after the slow reclosure dead time (tsdt) a slow reclosure is operated on fault detected later than td1 but within the reclaim time tr; once the reclaim time has elapsed, the delayed reclosing is issued.

TestThe test function allows the checking of each 50-51 and 50N-51N protection function threshold by means of the introduction of a dummy signal, with twice the setting threshold value and duration as to cause the start and/or tripping of the threshold itself, into the input circuit stages of the relay. This test does not include checking the system measuring transformers and the relevant connec-tions to the digital protection relay. Having activated the test function mode, the threshold relating to the protective function to be checked and the relevant test method must be selected. The latter may or may not include changing the status of the output relays assigned as the selected threshold start and /or trip. For the thresholds relating to protective functions 50 and 51 the dummy signal is applied simultane-ously over all phases. Example, with setting t>inv = 1 s, the operate time for the fi rst element 50/51is:
10 s with IEC/BS A characteristic13.5 s with IEC/BS B characteristic26.6 s with IEC/BS C characteristic
In cases involving selection of the test mode without any changes in the status of the output relays (“blank” Testing), upon tripping of the selected threshold, the corresponding LED is lit and the test outcome recorded as the most recent event. The test condition is shown by means of the blinking green LED ON.[1]
Test I> ledTest I>> ledTest I>>> ledTest IE> ledTest IE>> led
In cases involving selection of the test mode with changes in the status of the output relays, at the start and/or tripping of the selected threshold the corresponding programmed output relay is switched, the corresponding LED lit and the outcome recorded as the most recent event. The test condition is shown by means of the blinking green ON.[2]

The relay self-test function classifi es relay operational anomalies according to three levels: - MINOR ANOMALY: The device continues to function within the possible limits with the protective devices activated; - MAJOR ANOMALY: Operation of the device may be corrected by the operator by resetting the initial (default) confi guration and hence the desired settings; - FATAL ANOMALY: All logic and protective functions are inoperative and the relay must be returned to the factory. The internal self-test function is capable of detecting the following anomalies and indicating them by means of messages: - defective auxiliary power supply (FATAL ANOMALY); - output relay coil breakage (FATAL ANOMALY); - alteration of the calibration data stored in EEPROM memory (FATAL ANOMALY); - alteration of the parameters (threshold setting, times, relays… etc.) in EEPROM memory (MAJOR ANOMALY); - alteration of the data (counters, records, ...etc.) in EEPROM memory (FATAL ANOMALY);Upon detection of at least one of the above mentioned anomalies, the output relay programmed for Self-test is switched and the information is recorded (latched).

Core balanced CT[1]
Proper installation is shown in fi g. 1a and 1b.The current balance transformer, when used for measuring residual current, must be crossed in the same direction by all active conductors and hence, also by the neutral conductor if distributed, with the exception of the ground connection protective conductor. The drawing below shows cases of assembly of the toroid on unscreened and screened cables; prior to proceeding with assembly, it is necessary to check that there are no screen-to-ground connections upstream of the sensor.
In order to ensure a linear response from the sensor, the cables must be positioned in the centre of the transformer so that the magnetic effect of the three cables is perfectly compensated in the absence of residual current (Fig.2a). Hence, the assembly indicated in the drawing of fi g.2b, in which phase L3 causes local magnetic saturation whereby the vectorial sum of the three currents would be non-null, should be avoided. The same considerations also apply when the sensor is positioned near bends in the cabling. It is recommended that the transformer be placed away from bends in the conductors).The use of a balance transformer with an inside diameter about twice the diameter of the the cable going through it is recommended.
Note 1 Use of a toroid is recommended when high sensitivity is required (NA011#xxx2 and NA011#xxx3 versions

EarthA protective ground connection is required, which must be connected to the suitable screw with a separate lead of at least 2.5 mm2; the connection from A21 or a22 terminal and the ground srew is also required.[1]
CT amperometric inputsThe amperometric input circuits are assembled inside the fi xed module, so no short circuit on the secondary CTs must be provided when the removable module is pulled outIn the event of case replacement, some camps must be provided externally to shorting the second-ary CTs circuits to avoid secondary open circuit of CTs that may endanger equipment or people.
When making the current connections, attention must be paid to not exceeding the performance of the line current transformers. To be exact, the total load, constituted by the protective relay, any other protective relays or measuring instruments and the resistance of the connections, must not ex-ceed the line CT performance. In particular, consumption of the relay input circuit must not exceed 0.2 VA while the load (expressed in VA) constituted by the conductors is given by:
0.018 × L × In2 / Swhere: L the overall length, expressed in m, of the two conductors in relation to each phase; In nominal current of the line CT expressed in A;S cross sectional area of the current conductors expressed in mm2.It is recommended that cabling of a suitable thickness be used in order to limit wear of the CT sec-ondary circuits.
LPCT amperometric inputsThe amperometric input are designed for Low Power Current Transformer with 100 A - 22.5 mv ratio. Connections to NA011 device must be carried out by means RJ45 plugs, forming a part of the Trans-former.[2]
Note 1 The A21 and A22 terminal are link together inside the relay

Binary inputsThe dry input circuits, despite being galvanically isolated, must preferably be supplied with the same auxiliary voltage of the control panel.The inputs are polarity free with wide voltage range.
The optocupled inputs are immune to transitory interferences, however the following recommenda-tion must be considered in high disturbed environments:
Position input wiring away from high energy sources.Use shielded cables with ground connection on only one end (preferably at the relay side.
Output relaysFour output relays are available (SPDT, type C):
K1, K2 and K4 (trip relays).K3 (signalling relay).
It is advisable to verify that the technical characteristic of the contacts be suitable for the applied load (about current, nominal voltage, make and break current , etc..).All contacts are shown in de-energized state for standard reference
RS232 portThe link from PC and NA011 serial port must be established by means a L10041 cable.
When no RS232 port is available on Personal Computer, a suitable USB to RS232 converter must be employed.After installation, the same communication port must be selected to defi ne the Thysetter parameters (typically COM4, COM5,...).

7.2 MMI (Man Machine Interface)
On the front panel there are eight buttons which allow the user to perform all the settings, reading and modifi cation operations.
The adjustment of the settings and the operation mode of the output relays must be performed while the unit is electrically powered; the alphanumeric display shows the necessary information with reference to the operations performed through the keyboard. All preset values are permanently stored in the nonvolatile memory.The buttons take the following operations:
- (Up) move the cursor upwards to the preceding menu options
- (Down) move the cursor downwards to the subsequent menu options
- (Left) move the cursor upwards to the preceding menu options
- (Right) move the cursor downwards to the subsequent menu options
- (Enter) access to the selected menu with the option of modifying any given parameter
- (Reset) abort the current changes and/or accessing the previous menu
At power-up, the display shows the text:“THYTRONICNA011-adate and time: (01/01/2000 00:00”The ON green Led points out the auxiliary power supply voltage (permanent lighted) and possible faults (blink lighted).The display backlight is automatically activated when any key switch is set.
By means of the (Up) or (Down) buttons, it is possible to cyclically browse through the menu op-tions: Read, Set, Oscillography, Communication, Test, Reset, Time, Option
Having identifi ed the sub-menu of interest, it is possible to gain access by using the (Right) button
and then analogously, run through the relevant options by using the (Up) or (Down) buttons. The full menu tree and some examples are showed in the following pages (numerical values and settings are pointed out as examples and does not agree with real situations.
Reading variables (READ)All data (measure, settings, parameters, etc...) may be displayed:“Measures >”“Digital inputs >”“AutoReclose - 79 >”“Circuit breaker >”“Counters >”“Last fault >”“Info >”“Protection trip >”“Self-test >”

ResetInside the Reset menu the clearing of counters (Reset counters) LEDs and relays (Reset alarm) may be operated.
DEFAULT (Option)Available inside the Option menu are the confi guration parameter reset (Default) commands.Set default PARSet default REEIn case of any anomalies detected by the self-test function, where confi guration data has become corrupted, it is possible to restore the factory default settings. In particular, using the command “Set default PAR”, the calibration data is restored (thresholds, times, output relay assignment etc), whilst with the command “Set default REE” all the updated variables (counters, ...etc) and the serial com-munication parameters are automatically reset. Except for extraordinary situations, it is not necessary to use such commands which in any case allow the restoration of the factory set default values following an anomaly. Following use of this command, it is necessary to then proceed with the setting of the desired set-tings and/or the calibration of the voltages just as in the case for first installation.
Data/time setting (Time)To effect a change, (year, month,...) the modifi cation may be confi rmed by using the key. Likewise the Set menu the modifi cation in progress status is highlighted by the symbol “E” fl ashing in the upper right area of the display.
Subsequently, it is possible to change the parameter by means of the or keys (the “E” symbol continues to flash to highlight the Editing status); upon reaching the desired value, it is necessary
to once more use the key. Acceptance of the change is indicated by the disappearance of the flashing “E” to be replaced by the symbol “!”. Differently from the Set menu the changes are stored and became active immediately without the Store command.
Circuit breaker commandsBy means of the (Open) and (Close) keys the circuit breaker command may be issued.The committed output relays must be enabled inside the Set \ Relays menu.
Note 1 The tests are active only if the selected function is assigned to an output relay

7.4 MAINTENANCE
The devices do not require any particular maintenance; all circuits use high quality static com-ponents, the subassembly products undergo dynamic checks on their functioning before the fi nal assembling of the complete equipment. The dedicated circuits and the fi rmware for the self-test function continuously check the relay operation; the continuously operating auto-zeroing function dynamically corrects the measuring errors due to offset, heat dependent drifts, aging of components, etc.The microprocessor is equipped with a watch-dog circuit which restores the correct operation of the fi rmware in case of fault.The possibility of reading the value of the signals measured on the display (the relay used as an am-meter) allows one to check both the system parameters and the operation of the protection relays at any time. The relay can be preset as well to show the current values referred to the nominal current of the current transformers, as directly in primary amperes (according to the preset value of CT’s nominal primary current); the same is done for the input voltages.If connected to the central control unit, all data available on the display can be checked and pro-cessed thus performing a continuous check and maintenance.
7.5 REPAIR
No repair of possible faults by the client is foreseen; if following to any irregularity of operation, the above tests confi rm the presence of a fault, it will be necessary to send the relay to the factory for the repair and the consequent settings and checks.
7.6 PACKAGING
The devices must be stored within the required temperature limits; the relative humidity should not cause condensation or formation of frost.It is recommended that the devices are stored in their packaging; in the case of long storage, espe-cially in extreme climatic conditions, it is recommended that the device is supplied with power for some hours before the commissioning, in order to bring the circuits to the rating conditions and to stabilize the operation of the components.
