Please refer to Section 10.0. for a listing of plant documents that may be affected by the results of this calculation. l 5.2. The 273/274 series 4.16 kV system undervoltage relays examined in this calculation are considered to i be functionally identical and, as such, the data collected from each device can be considered independent samples from the same distribution. Therefore, the data can be combined to statistically determine the expected drift of the relays. 5.3. If the absolute value of the mean (average) of the final (second outlier drift points column) data set is less than 0.1 percent of setpoint, then a bias is assumed to not exist and the absolute value of this i mean is added to the standard deviation adjusted to correspond to a 95 %/95 % probability / confidence. If the absolute value of the mean is greater than 0.1 percent of setting, then c bias with the appropriate sign is assumed to exist and it is not added to the adjusted standard deviation. If a bias dces exist it is incorporated into the nominal setpoint calculation via the overall device drift calculation. 5.4 It is assumed that the data provided in Reference G.S. were performed in accordance with References P.5., P.6. and G.8. and thus any repairs and/or calibration adjustments made to the relays were recorded on the Relay Test Reports (Ref. G.S.) during the time period examined. It is also assumed that, unless otherwise noted on the Relay Test Reports (Ref. G.5.), that the As-Left value is the same as the As-found value. 5.5. 'Ihe Potential Transformers (PT) are assumed to have an uncertainty of 1.200% of the relay tap setting. This is based on Reference G.2. (Attachment D) worst-case li error. It is also assunied that this error cannot be applied to the time delay portion of the relay as the " process" is time which is a constant as opposed to the errors associated with the voltage IT. 5.6. It is assumed that the switchgear room is an environmentally controlled area with minimum fluctuations in humidity and temperature. It is assmned that the ambient temperature for the relays located inside the switchgear room (Ref. G.4.) will be maintained within the vendor specified operating temperature range for the relays. The operating range is -30*C to +70*C [-22*F to ISPF] (Ref. V.I.). Any error associated with the " variation in operating voltage over the temperature range 20-40 deg C: 0.5 volt, typical" (Ref. V.I.) is assumed to be included in the as-found / as-left voltage drift error term. The ambient temperature during calibration is also assumed to be within the operating temperature range of the relays (References P.S. and P.6.). Given these assumptions the i relays will only be ana'yzed for normal conditions. 5.7. According to the PBNP Setpoint Methodology (Ref. G.I.), only mechanical desices experience a l permanent output shift due to a seismic event. Ref. G.I. also assumes that for scismic events greater 4.16KV Reactor Trip Undervoltage Matrix Relays Uncertainty / Setpoint Calculation PBNP Setpoint Venfication Project i GWS 11/23/98 KLD 11/23/98 DUKE JOB No. 00087.00.0007.33 PAGE l 1 5 0 GWS 6/30/97 SKV 6/30/97 Engineering CALC No. PBNP-IC-33 l BY DATE CHECKED DATE & Senices of29 REV Ic33r1. doc

- j. than an Operating Basis Earthquake, instrumentation will be recalibrated prior to any subsequent
, accident; thus, negating any permanent shift that may have occurred due to the seismic event. i 5.8. From the PBNP Setpoint Methodology (Ref. G.1), statistically derived as-found/as-left drift values include the effects of M&TE used in past calibrations. To maintain the validity of these values, it is assumed the M&TE used to perform future calibrations will be of equivalent accuracy to the M&TE
- used in the past calibrations on which the as-found/as-left drift data is based.
5.9. The intent of this calculation is to provide drift value:; for the 273/274 relays for a two year 4 surveillance interval. Ideally, the intervals over which the drift is calculated will be 730 days for a i two year interval. However, since the typical calibration interval for these devices is one year, the Sliding Filter Approach, as described in Appendix H of Reference G.I. is used for this drift l evaluation. Since the PBNP Technical Specifications (Ref. G.6. (b)) allow for a 25% extension of i surveillance intervals, the combined drift data which has a time interval of 730 days i25% is included i in the data sets and is considered two-year data. J l 4

The spreadsheet cells are fonnatted to display three decimal places.

] 5.11. The analytical hmit for the 273/274 series relays time delay setting will be defined as the maximum j reactor trip response time which is 1.5 seconds (Section VIILE of Ref. C.I.). This analytical limit 1
only applies to the reactor trip function of the undervoltage relays, namely the 273/274 series relays. 5.12. Uncertainty values for voltage settings are presented in percent of voltage tap setting rather than ! voltage setting span since the relays do not have an instrument span (Ref. V.l.). Instead the relay has i seven(7) tap settings that may be selected. Uncertainty values for time delay settings are similarly presented in percent of time delay setting since there isgtime delay setting span (Ref. V.l.). fcggg 5.13. The Low and High Tolerances for the Unit 2 273/274 series relays shown on Page 36 of Reference P.6. are outside the range of the setpoint and are assumed to be a transcription error.

7.4.2. Nr minal Trip Setpcirt, Alltweble Value, and Retry Error Definitions From Reference G.I. the Nominal Trip Setpoint (NTSP) is calculated using the following equation: l l NTSP = ALi(TLEn
- PS) .
where AL = AnalyticalLimit TLEn = Total Loop Error for normal >.' anditions
- j. -PS = Process Span l Since the devices are relays the Process Span term will be replaced with the Actual Trip Setpoint (ATSP), .
therefore; } , l NTSP = ALi(TLE
- ATSP)
The Total Loop Error will always be for normal conditions (Assumption 5.6) so the "n" subscript will not l be used. The "i" is used as these signs are dependent on the direction of conservatism. I The Allowable Value (AV) is calculated using the following equation from Reference G.I.; AV = ATSP i(Trip RE
- PS) where ATSP '= ActualTrip Set point - i RE = Rack Error = Relay Error PS = Process Span The Relay Error is calculated in a similar way to the TLE except that the process term (Trip PT) is not included:
RE = (A + D + M + V + P + T + H + R + S)v2 + B+ + B' l l l Since these devices are relays the Process Span will be equal to the Actual Trip Setpoint (ATSP), therefore; AV = ATSP $ (RE
- ATSP) 7.4.3. Nominal Trip Setpoint and Allowable Value Check Limit Tests The AV is checked using the following two tests according to Reference G.I.:
Check Limit 1 = AL i(S/PE
- PS) = CL1 Check Limit 2 = NTSP i(RE
- PS) = CL2 where AL = Analytical Limit S/P E = Sensor / Process Error NTSP = NominalTrip Setpoint RE = Relay Error PS = Process Span 4.16KV Reactor Trip Undervoltage i Matrix Relays Uncertainty / Setpoint Calculation PBNP Setpoint Verification Project l 1 GWS 11/23/98 KLD 11/23/93 DUKE JOB No. 00087.00.0007.33 PAGE O GWS 6/30/97 SKV 6/30/97 Engineering CALC No. PBNP-IC-33 10 REV BY DATE CHECKED DATE l & Services of29 Ic33r1. doc
- i-l Since these devices are relays the S/P E term shall be replaced with the Potential Transformer Error (pte).
Again the ATSP replaces the process span term. The equations then are as follows: l l CLI = ALi(pte
- ATSP) l CL2 = NTSP t (RE
- ATSP) j Again the "i" symbol is used to show that the sign is dependent on the direction of conservatism.
Note that for the tims delay settings the PT / process effect is not considered. Therefore for the time. delay ! setting: TD CL1 = AL (0

- spreadsheet file IC33.XLS. See Table under Assumption 5.10.
7.4.4.1. Surveillance As-Found/As-Left Data ne surveillance as-found/as-left p.ckup and time delay relay data recorded on the test data sheets l provided in Reference G.5. were entered into the appropriate spreadsheets. He surveillance test data sheets document the calibration and maintenance performed on the relays. Any pertinent maintenance information is entered into the comments section of the spreadsheet. The day, month and year that each surveillance procedure was performed, was entered beside each set of as-found/as-left readings. Per Reference G.I. an Excel @ function, which determines the number of days between two dates, was used to determine the length (in days) of each surveillance interval. I yr to 2yr Surveillance interval (days) = (as-found date - 2yr Previous as-left date) This method is the Sliding Filter Approach as described in Appendix H of Ref.G.I. This approach allows use of one year surveillance intervals for two year drift determination (Assumption 5.9). If the surveillance interval calculated above was less than .148 days (24 months-25%) or greater than 912 days (24 months +25%) then the data point was removed. After the above conversions are complete then the as-found / as-left data, as well as the final drift number, is considered good for 24 months i 25% which is a maximum of 30 months. Raw drift data points were then created by using the following equation to create each point: Raw Drift Data Point = (as-found value - 2yr Previous as-left value)

Briefly, the absolute value of the drift data minus the data set mean is compared to the l Outlier Criteria Multiplier multiplied by the data sample standard deviation.

The outlie criteria were selected from TABLE A of Appendix H of'Reference G.I. (See also ~ TABLES! of Excel @ file IC33.XLS) based on the number of data points in the given data set. If
~ the number of da'a points in the given data set is not represented in the table, linear interpolation was used to determine the appropriate criteria value.
The data sets with the outliers identified and removed are beside the columns of the spreadsheet containing the raw data sets. The mean standard deviation and the number of data points per data set were recalculated for the data sets with outliers and other filtered data removed. 7.4.4.3. Descriptive Statistics and Drift . The final outlier filtered column of data was copied to the next column, if the total number of I remaining points after outlier filtering was 95% of the raw data set number of points or greater, and ! 1 then sorted in ascending order using the Excel @ sorting capabilities. Beside the column of sorted 4 data, data points are rounded to five decimal places and then displayed to three decimal places in l percent of voltage or time delay setting. This column of sorted, rounded data is the data set that is used to calculate the drift value. This column is also analyzed for normalcy and used for the ;

Tests for Normalcy Normalcy testing is performed on each data set to determine ifit is normal or bounded by a normal curve. There are four tests which are performed in this calculation: Skewness l Kurtosis J Probability Plot Histogram An evaluation of these tests is given below. 7.4.4.4.1. Skewness and Kurtosis Skewness is the third moment around the mean (average) of the data and is used to describe the synunetry of the distribution. The Skewness should show that the data is symmetrical around the mean if the distribution is normal.

The Excel @ value obtained for Skewness is compared with the number obtained from Table B of i Appendix H of Reference G.I. This number is the distribution of Skewness at 5% and is selected I based on the number of points in the data set. If the calculated value of Skewness is greater than or equal to the value from Table B, then the data set may not be normally distributed. In this case the Skewness is said to be "Significant." If the number of data points is less than 25 then a Skewness test cannot be performed. I Kurtosis is a function of the fourth moment about the mean and is a measurement of the peakedness ) l of the data distribution (Ref. G.I.). Table C of Appendix H of Reference G.I. provides Kurtosis criteria values for data sets that have 50 data points or greater. In this case both data sets had 50 or greater points, thus the values for Kurtosis could be determined by matching the number of data points to Table C for the computed Kurtosis (b2 ) whichis: b = [(x - y)* 2 [(x - y)2 I where: x = data set points X = Mean of the data set The b2 Kurtosis value is then compared to Table C of Appendix H of Reference G.I. If this Kurtosis value is within the range defined by the table then the Kurtosis is said to be " insignificant" and the data set may be normal. If the value is not within the range then the Kurtosis is said to be "Significant" and it is unlikely that the data set is normal. The same test is performed on the Excel @ generated Kurtosis value (g2) which is compared to Table D of Appendix H of Reference G.I.

This shows that the voltage data set might be normally distributed. The time delay data set failed the Sk:wness and Kurtosis tests. This shows that the time delay data set may not be normally distributed. 7.4.4.4.2. Probability and Histogram Plots Per Reference G.I. a probability plot is a plot of the cumulative distribution function (CDF) of the data against a special grid. The grid is arranged such that, if the data in the data set is normally distributed, a plot of the data's CDF will lie in a straight line having a slope equal to the standard deviation of the data and a y-intercept equal to the mean of the data. Per Reference G.I. the probability plots are used to qualitatively examine the distribution of the data and determine ifit is normal. To aid in the evaluation of the probability plot and provide a n.cthod of comparison, a straight line having the slope and y-intercept indicated is also plotted on the grid. The evaluation of the probability plot is a discussion comparing the probability plot and the straight line representing a normal distribution for each data set. Ideally the probability plot 4.16KV Reactor Trip Undervoltage Matrix Relays Uncertainty / Setpoint Calculation PBNP Setpoint Verification Project GWS 11/23/98 KLD 11/23/98 DUKE JOB No. 00087.00.0007.33 PAGE l 1 O GWS 6/30/97 SKV 6/30/97 Engineering CALC No. PBNP-IC-33 15 REV BY DATE CHECKED DATE & Services of29 Ic33r1. doc
l I ,. 3 will lie directly on top of the normal distribution's straight line, however, since the data sets represent only a sample of the entire population, it is acceptable if the probability plot approximates the straight line representing the normal. The probability plots for the drift data are available in the associated appendices A and B for the l drift calculations. In general the data sets may not be normally distributed due to the lines falling well away from the normal distribution. Another test for normalcy is the Histogram Plot. This plots the frequency of occurrence of data I with a specific value versus the range of values the data can have. This is useful in showing the actual distribution curve of the data to see if the standard bell-shaped cun'e is apparent. ; The histogram is generated by comparing the data set with a " bin" which is a series of numbers that are selected to contain the data set. This bin is chosen so that it contains the data set and has enough resolution of munbers in order to create the histogram. The histogram is then generated showing the number of times a certain bin number is " hit." If the data set is normal it should l create a bell shaped distribution around a mean of zero(0). l The histogram plots for the drift data are available in the associated appendices A and B for the drift calculations. Neither of the histograms show the normal distribution cun'e for the data sets, therefore the data sets may not be normal. 7.4.4.4.3. Normalcy Conclusions and Binomial Approximation Given the four tests performed above it was concluded that the data sets may not be normally distributed. Thus a normal approximation of a binomial was performed on the data sets to validate that the drift value calculated using a normal distribution is a valid 95% probability / 95% l confidence bound of the drift. The binomial approximation involved comparing a selected drift value against the absolute value of the difference between each data point and the mean. If a data point met this condition then it is i considered to be part of the binomial distribution. The criteria is adjusted until 95% or more of the l points are within the distribution. This criteria is then considered to be the drift value. Since in both cases a binomial approximation was used, the initial value used is the drift normal distribution value originally computed. The number is approximated using the following equations for binomial approximation (Reference G. I .): X = dx(n)- yl < (o-
- m /95 95 + X))
X'= X N Note: included if there is no bias indicated N P - lower = X'-1.96QX'* (1 - X') / N where: X = the total number of data points that have satisfied the inequality. x(n) = individual data points of the data set. y = mean of the data set. o- = standard deviation of the data set. 4.16KV Reactor Trip Undervoltage Matrix Relavs Uncertainty / Setpoint Calculation PBNP Setpoint Verification Project l 1 GWS 11/23/98 KLD 11/23/98 DUKE JOB No. 00087.00.0007.33 PAGE 0 GWS 6/30/97 SKV 6/30/97 Engineering CALC No. PBNP-IC-33 16 REV BY DATE CHECKED DATE & Senices of29 Ic33r1. doc

m,3,93 = 95% probability / 95% confidence multiplier. P lower = X' converted to percent confidenc : of the binomial approximation. The X' and P lower values are essentially the 95% probability / 95% confidence levels for the binomial approximation. These are calculated using the equations above and the initial drift value (standard deviation multiplied by the 95/95 multiplier). The goal is to have both X' and P lower be l both equal to or greater than 95%. ! If the initial drift value fails to do this then a new criteria is chosen that does satisfy the inequality 95% of the time with a 35% confidence level. Thus the New X equation would be: l New ~ X = [ }x(n)-xl < (new ~ criteria) l The new criteria number thus becomes the drift value for 95% probability / 95% confidence of the

Given the NTSP calculated above, the margin between the ATSP and the NTSP may be computed: I ! Voltage Setpoint Margin = ATSP - NTSP = (90.00 - 83.52) Vac = 6.48 Vac l Since the above margin is positive the ATSP is considered acceptable given the AL and the calculated i NTSP. l l According to the Technical Specifications the 273/274 series relay Tech Spec Limits are all equal to 2 89.15 Vac which is (Ref. G.6. (c))"275% of normal voltage" (see also Section 6.1). Given the computation of AV above the Tech Spec Margin may be computed: i i Tech Spx Margin = AV - Tech Spec = (89.24 - 89.15) Vac = 0.09 Vac l Since the above margin is positive, the AV and the ATSP is considered acceptable with regard to the Tech l Spec value. 8.5.2. Nominal Trip Setpoint and Allowable Value for the Time Delay Setting l From Section 7.4.2 the Nominal Trip Setpoint (NTSP) for the Time Delay (TD) setting is calculated using the following equation: l TD NTSP = TDAL -(TD Trip TLE
- TD ATSP) where TDAL = Time Delay Analytical Limit TD Trip TLE = Tinie Delay Trip Total Loop Error TD ATSP = Time Delay Actual Trip Setpoint p The signs are negative as the shorter time spans are more conservative.
The time delay analytical limit (TDAL) is given from Ref. C.I.

Note that for the time delay settings the PT / process effect is not considered (see Section 7.4.3) and the TD Trip RE term is equal to the TD Trip TLE term for the time delay setting (see Section 8.3.2). Therefore for the time delay setting: TD CL1 = l TDAL -(0

As shown in the table above, the existing reactor trip relay voltage and time i delay setpoints (ATSP) are currently acceptable with respect to the Tech Spec, Analytical Limit, Allowable Value, and the calculated NTSP.
- The maximum undervoltage relay delay (Max UV Relay Delay) shown in the table above was taken 1 from Revision 0 of this calculation and is used in Ref. C.1, in order to calculate the AL. Since this l maximum delay value is conservative with respect to the revised calculated TD Allowable Value and TD Acceptable As-Found values it may be maintained within Ref. C.I. as the maximum relay delay so that no l revision to Ref. C.I. is necessary.

Types 27, 270, 27H, 590, and 59H. See the section on Testing for single-chase voltage relays covered by earlier issues of this instruction book. Tno relay is housed in a case suitable for conventional semiflush panel mounting. All connections to the relay are made at the rear of the case and are cleerly numoarec. Relays of the 4118, 411R, and 411C catalog serias are similar to relays of sno 2118, 211R, and 211C series. Both series provide the same casic functions and tro of totally drawout construction; however, the 4118. 411R, and 411C series relays orovide integral test facilities. Also, secuenced disconnects on the 411 series pre-vsnt nuisence operation during withdrawal or insertion of tne relay if the normally-open contacts are used in tne aco11 cation. Host settings are made on the front canel of the relay, behind a removable clear i olastic cover. rolay cover. The target is reset by means of a pusnbutton extending through tne ORECAUTIONS following precautions should be taken when apolying these relays: Incorrect wiring may result in damage. Be sure wiring agrees with the connection lu_,sgram for the 0 articular reiay before energizing. Important: connections for the ' \ 411 catalog series units are different from the 211 series units.
- 2. Acoly only the rated control voltage marked on the relay front canel. The proper colari yt must ce coserved when the ce control power connections are made.

ImSo'tsnt? connections are different for 4118, 411R, and 411C sertes untcs compared to 2118, 211R, and 2ttC unscs. Contro1 power must be connected in tne < proper polarity. I For ralays with dual-rated control oower* before energi21nQ, withdraw the relay frce its case and inspect that tne movable link on tne lower printed circuit ocard is in I tne correct position for the system control voltage. (For units rated 11ovde, the I link should be placed in the position marked 125voc.) Relays rated for use with 12Ovac control power have an internal isolation transformer connected to relay terminals 7 and 8. Polarity of the ac control power to these i terminals need not be observed. l These relays hsve metal front panels which art connected througn printed circuit Doard runs and connector wiring to a terminal at the rear of the relay case. The terminal is marked 'G". In all applications this terminal should De wired to grounc.

PICKUP (VOLTS) The pickup tads are 18 belled by the actual value of'aC input voltage which will cause the relay to operate. Note: operating voltage values other than the specific values provided by tne taps can be obtained by means of an Internal adjustment po tenti ome ter. See section on testing for setting procedure. on these relay models there is nn adjustment for the differential between the operate I I and reset voltage values. %./ TIME DIAL The time dial taos are identified as 1,2,3,4,5,6. Refer to the time-voltage charac-teristic curves in the Application section. Time dial selection is not providied on i relays with an Instantaneous operating cnaracteristic.

An operation target is provided. The target is set electronically when the output contacts transfer. The target will retain ita indication on loss of de control power. In order to reset the target, normal dc control power must be present and a
" normal" ac voltage condition must exist; in other words, for an undervoltage relay tne voltage mest be higher than the sat point, and for overvo~ltage releys. 1ower.
APPLICATION DA fA The ABB circuit-ShieldTN single-pnase voltage relays covered by this instruction book provide a wide range of application including undervoltage protection for motors, over and undervoltage protection for generators, and automatic bus transfer,.

The Type 270 relay nas a definite-time characteristic with 2 ranges available; c.1-1 sacond and 1-10 seconds, as shown in TVC-605820 and TVC-605821. l Undervoltaae Relays. Tvoe_. 274 cataloo series 2119. 211R. 4118. 411R-Typtcal applications include instantaneous undervoltage detection for bus transfer schcmes, and for generator intertie schemes. The low range relay is used as a l residual voltage detector in motor bus transfer schemes. l Typical connections are shwen in Figure 3. The relay has an instantaneous operating time as shown in TVC-60581g. j Overvoltace Aelays. Tvoc 59H and Tvoe 690. catalog series 211C and 411C: Thes3 instantaneous and definite time overvoltage relays ars companions to the Type 27H and Type 270 undervoltage relays, and offer similar characteristics where overvoltage protection is required.
]
! "we time voltage characteristic for the Type 590 is given in TVC-605839. For the as 59H the maximum operating time above 1.09 times pickup is 16 milliseconds. I l l l l 0 i l l Notas on *he Use of AC Control power - l In asneral the use of a station battery to provide a reliable source cf tripping and control power is preferred. However, many of the relay types described in this IB cro cvailable for use with 120 vac control power. The output contacts may be used in a 120 vac circuit or in a cacacitor trip circuit where the capacitor voltage is no more than 170 vde nominal. (Consult factory if the higher rating is esquired: * -CAP
- l catalog suffix.) The control power for these relays should never be taken from a I cactcitor trip circuit as the voltage is too high and the relay will drain the
!. etocc1 tor in the event of loss of AC supply. l Tyon 27 and 'ype 27D Undervoltage Relays used with 120 van control power in the i "s31f-powered
- mode, with both signal and control power taken from the same source, will not maintain their timing characteristics if the voltage drops below I approximately 85 volta. The relay will trip immediately. If this characteristic is
- uncoot raole for a particular application, the Type 27H instantaneous relay should be i uccd followed by a pneumatic timer with time delay on cropout. A contact from the timer would be used to trip. The timer wculd be picked uo by a contact of the Type 27H under " normal" line conditions. With undervoltage or loss of voltage, the timer would time out and close its contact in the tripping circuit. If the voltage loss were momentary, the timer would allow riding through the loss without tripping.
This -arrangement thus makes the time delay independen*,of control powar and retains ths eenefits of accurate voltage sensing provided by the Type 27H relay.

Follow test instructions to ! i verify tnat tne relay is in proper working order. We recommend that an inoperative I relay oe returned to the factory for repair; however, a schematic diagram, and in I some cases a circuit description, can be provided on request. Renewal parts will be cuoted by the factory on request. There are many earlier versions of these single-phase voltage relays which are now ooso)ete and nave Deen superseded. If you have a relay which has its front panel stimoed with Instruction Book IB 16.4.7-2, of the ocok, you should recuest Issue D from butthe which is not covered by this Issue E il factory. Also see para 9Paph 6 on oosolete relays. 1 211 series Units ' Orawout circuit boards of the same catalog number are interchangible. A unit is icentified by the catalog number stamped on the front panel and a serial numbe r i stamoed on the cottom sioe of the drawout circuit board. I 1 Tne board is removed by using the metal pull knubs on the f ront panel . Removfng the ~ ocard witn cne un t : to service may cause en undesired operation. 1 I An la moint extender ocard (cat 200x0018) is available for use in troubleshooting and ca11 oration of tne relay. 411 Series Units H3tal handles provide leverage to withdraw the relay assembly from the case. Removing
- ths unit in an aoplication that uses a normally closed contact will cause an cocration. The assembly is identified by the catalog number stamoed on the front 8,
l ognel and a serial numoer stamoed on the bottom of the circuit board. [ I i Test connections are readily made to the drawout relay unit by using standard Danana ! elug leads at the rear vertical circuit ocard. This rear board is marked for easier { t identification of tne connection points.

- 2. HIGH POTENTIAL TESTS ]dI High potential testa are not recommended. A hi-pot test was performed at the factory $
before snipping. If a control wiring insulation test is recuired, partially withdraw the relay unit from its case sufficient to break the rear connections before applying f't the test voltage,

- 3. BUILT-IN TEST F11NCTION (
Ba sure to take all necessary precautions if tests are run with the main circuit En3rg12ed. Tna euilt-in test is provided as a convenient functional test of the relay and assoc-iotcd circuit. When you depress the button labelled TRIP, the measuring and timing circuits of the reiny are actuated. When the relay times out, the output con tacts iransfer to trip the circuit breaker or other essociated, circuitry, and the target is i i
~
dic$ layed. The test button must be held down continuously until operation is - obtained. For the undervoltage relays, the timing is equivilent to that for a [ comolete loss of voltase. l I . L Attsdassi C su Met & .I Csis, Ms. ffn912.- ?]

\ Follow calibration Drocedures under paragraph 5. on inverse or definite-time relays, select Time Dial #3. For undervoltage relays check timing by dropoing voltage from 120 to 0 volta. For overvoltage relays check timing by increasing voltage to 150g of pickup. Telerances snould be within +/-5x for pickup and +/-10s for timing.
Caiioration may be adjusted to the final settings required by the application at this time. ,
- 5. CALIBRATION A typical test circuit is snown in Figure 3. Connect the relay to a proper source of control voltage to maten its nameplate rating and internal plug setting for cual-rated units. The ac test source should be harmonic-free. Sources using ferro-reso-nant-transformer regulators should not be used due to hign harmonic content.
For relays with time delay, the time-dial tap pin should be placed in position si l (fastest) when check 1ng pickup and drecout voltages. The voltage snould be varied l slowly to remove the effect of the time delay f rom the voltage measurements. l l Pickup may be varied between the fixed tap values by adjusting ;he internal pickup calibration potentiometer. For 211 series units the 18 point extender board provides easier access to the internal Dots. Place the voltage tan pin in the-nearest value and adjust the internal pot, repeating the test until the desired e perating voltage !- 1s octained. If the internal pot has insufficient range, move the tap pin to the next closest value and try again. Similarly the time delay may be adjusted higher i l or lower snan tne values snown on the time-voltage curves by means of the internal pot. The internal calibration pots are, identified as follows:
