' PURPOSE t

'Four Limit Control Switches manufactured by NAMCO Controls were

. subjected to a scistic qualification. test for Class E equipment to be t

used iri nuclear-powered electrical generating plants. The four svitches are a representative sample of EA180-ll302 and EA7h0-80100 limit switches

.'i 1

and the scismic test results vill be considered as representative of the characteristics of each-switch scrics.

The tests involved single-axis sinusoidal vibration in cach of three. mutually perpendicular axes parallel to the major dimensions of the switch, in accordanco with IEEE 382-1972, 323-1971, and 37 l+-1975 The test program was conducted by Dr. Edvard J.

TEST EQUII'ME!!T The test equipment consisted of two different shake tables.

The firnt shake table was a mechanical device for large amplitude - low frequency vibration.

Maxirnum peak to peak displacement was twelve inches, giving a singic amplitude of six inches.

Displacements down to.025 inches single amplitude could be achieved.

The mechanical i

i chake table uns used to test over the frequency range 1-20 IIz.

The second device was an electro-dynamic shake table for small amplitude -

i high frequency vibration.

Peak to Peak displacement up to 0.4 inches could be achieved.

The electrodynamic shake table was used to test over the frequency range 20-35 Hz.

Both shake tables were taonitored for wave form by an accelerometer mounted on the table.

During the test procedure the switch was energized electrically l

vith 125 volts DC at 1/2 amp. and monitored continuously for contact opening of 2 tailliseconds or greater.

The switch was tripped from the actuated position to the unactuated and back during the test procedure and monitored for contact opening.

Switch tio, 32,EA-180-11302 Attn : 1ir. Ed Solem

Dear Mr. Solem:

This is in reference to your letter of January 15, 1980 j

concerning our report of the vibration test for Switch flo, 32, EA-180-11302, to determine whether cross-coupling would j

cause the switch to trip and 'thus fail.

~O The test procedure is the same as that described in j

our report of June,1977, where Switch I-lo, 32,EA-180-11302 was subjected to the seismic qualification test.

In the-test of Switch llo. 32 for cross-coupling, the switch was tested in the Y-component as specified by the Acre Cleveland Development

Company,

!!o failure was observed during the test procedure,

Behavior of The Test Circuit t

The test circuit was designed to detect switch openings of more than a pre-set time.

For the purpose of these tests the time was set at 2 milliseconds.

During the seismic tests it was reported that the circuit was triggering.

Therefore, i

personnel from Acme-Cleveland Development Company observed the situation.

'i O

It was found by use of an oscilliscope that_the circuit

)d i'

was responding not to contact openings but to small changes in voltage due to increases in contact resistance as the contacts moved over one another.

Although th.e decreace in voltage may have lasted for considerable times, no contact openings of more than 2 milliseconds were observed in that instance.

At that.

point it was decided that whenever the circuit was triggered the oscilliscope would be used (by Dr. Edward J. Walter & As-sociates' personnel) to determine if there was a contact opening of more than 2 milliseconds or not.

APPEllDIX C MIAI.YSIS OF CROSS COUPI,ING Abstract The following analysis was undertaken in order to establich that'significant cross coupling does not exist in the switch mechanism under test.

The inherent constraints on the motion of noving parts were used as a basis for the analysis.

In one case it was necessary to establish the non-existence of significant cross coupling experimentally.

O Panc 1 of 4 (C) 10-36 l

APPENDIX C SEISMIC TESTING / CROSS COUPLING

,All of the parts and assemblics of which the switch is comprised may be. classified into three categories depending upon the geometric constraints upon their movement uithin the unit.

The first category is components free to revolve about an axis but which have balanced angular masses about the axis.

The recond category is components which are free to rotate about an axis within a range the limits of which are 9 to either side of a principal axis of the switch.

The third category is parts which are constrained to linear movement in a line which is within 9 of a principal axis of the switch.

The contact lever arm assembly (83) is in the first category. As the at. gular moment of inertia of this component is balanced about the central axis, vibration will not result in any t'orque about the axis.

Therefore, it is not necessary to consider this component-in the analysis of cross coupling.

Components belonging to the second category are the IcVer shaft assembly (94), the latches (19), and the rocker arm (65).

The parts belonging to the third class are the contact carrier plate assemblics which are located at the ends of the contact icver assembly (83) and the roller assembly (75, 80, and 81).

The linear motions of Category 3 components, except (75, 80, and

81) and the tangential motions of the Category 2 components, are all within 9 of the Y axis.

Therefore, a vibration with a deviation of 9 from the Y axis would cause a higher g loading along the direction of motion of thene componentn than motion directly along the Y axis.

1 Page 2 of 4 (C)

(

m-U

Appendix C 2/15/80 Scistaic Testing / Cross Coupling Therefore, the g Icvels used in single axis testing should be multiplied by a factor of.98 (i.e., co* sine of 9 ) in order to compensate for possibic ef-fcc t t: due to multi-axis vibration.

Movement of components (75, 80, and 81) is within 9 of the X axis.

Therefore, it could cross couple with the Y axis movements of the other Category 2 and Category 3 components.

The X axis movements of (75, 80,

'and 81) cannot cause any Y axis movements directly.

They can, however, allow Y axis movements of (65) and (94).

It is shown below that movements of (94) cannot occur at 10 n's due to the preloaded force of Spring (107):

V In order to determine that movement of (65) due to cross coupling was not a factor in these tests a separate test was run with components (75, 80, and 81) completely removed.

This conservatively simulates any cross coupling betueen components (75, 80, and 81) and (65).

Due to the above considerations, cross coupling is not considered limiting in this unit; and therefore, singic axis vibration testing is considered suitabic.

10.0 TEST REPORTS (C0NT'D).

10.2 Suppicmentary Testing for Short Travel Swi tches.

4 An excerpt f rom EA180 Quali fication Test Report, Revision 1, dated September 5, 1978.

A copy of this report is included in this sec-tion.

~

Those switches of the EA-180 series which contain a short O

travel mechanism differ tuterna117 from.the standard travel

~

versions'in-some respects.

It was, therefore, felt that it uas necessary to test a short travel model up through the scismic s

portion of the test in order to verify that the internal mechanism of this suitch was not subj ect.to scismic failure.

The tests' conducted were the same as those conducted on the switch #61 in the body of the report except that the LOCA tests were not performed.

The short travel switch which uas tested (#83, Model EA-180-14302, Rev. C) maintained optimal electrical performance throughout all portions of this test.

During the seismic test-ing the trip position of this switch was observed to change -

as noted in the seismic repo:t.

The maximum change was.107" and the direction of change was such that the switch would v

actuate earlier in the tripping cycle than it had prior to the scismic testing.

Cross coupling tests were not necessary for this switch.

This was because as they were for the long travel mechanism.

the parts #75, 80 and 81 of the' normal long travel mechanism i

(see page 5 of'the main body of the report) are not prescht in sub-this switch, and part 62 which replaces these parts is not l.

I I

jcet to movement in the X axis.

this switch It uns not considered necessary to LOCA test travel versions of the switch covered in the main because short body of this report will be built with identical scaling Q

mechanisms (i. e. gaskets and 0-rings) to switch #61.

I i

The switch was heat aged at 200 F in a high humidity chamber from 12/23/77 to 1/1/78.

The open contact resistance on a Meggar instrument reasured above 1000 megohms (infinity) before and af ter the heat age test and the closed contacts passed a current of.086 amps at 100 V.D.C.

The switch uas wear life cycle tested for 100,000 cycles at 70 RPM using a cam to actuate the lever arm.

The load on the suitch was.5 amps @ 100 V.D.C.

The test was from 1/3/78 to 1/4/78.

After the uear cycle test the contact resistance was over 1000 megohms (infinity) and the closed contact current wao.086 amps.

g

/

s The suitch was irradiated at Isomedix, Inc. from 1/12/78 to

'~'

1/31/78.

The switch was irradiated with a cobalt 60 cource.

The total irradiation applied was 204 Mrads with an energy level of 1.25 Mev. at 1.2 Mrad /hr. rate.

The open and closed contact resistance and current were the same values as before the irradiation test.

The switch was seismic tested by Dr. Edward J. Walter &

Associa tes from 2/1/78 to 2/13/78.

The seismic tests consisted of fragility test and plant induced vibration simulation.

After the seismic test the open contact resistance was above 1000 megohms (infinity).

Before and after the seismic test the closed contacts passed a current of.036 amps at 100 V.D.C.

The test program for switch #83 was completed on 2/13/78.

The data is attached.

This will nummarize parameters pertinent to the irradintion 'of three switches per your purchaue order no. DC-97214, dated January 12, 1978.

The unito were identified as switches 81A, 82A, and 83 The switches were place'd in a cobalt-60 gamma field a't a dose rate

-Oor1.2laradperhour.

The~ switches were expocod for 170.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, yielding a minimum donc of 204 megarado.

Donimetry was performed using an Atomic Energy of Canada Limited

,'( AECL) Red Perspex. system with Type BC,-2 readout.

Calib'ation of r

the Perspex in made by AECL using Ceric dosimetry traceable to the U.S. National Bureau of Standards.

Icomedix regularly crocs-calibraten its AECL system with an inhouse Harwell Tercpex cyntem, and makes nemi-annual calibrations directly with MBS, using the UBS Radiochromic Dye'nyutem.

A copy of the donimetry correlation re-port in available upon requect.

Irradintion was conducted in air at ambient temperature and prennure.

Radiant heat from the cource heated the camples nomewhat, but the temperature did not exceed 100 F, an indicated by previcun measure-ments on an oil solution in the name relative position.

l Irradiation was initiated on January 15, 1978, and wan completed on January 26, 19/8.

an acceleration 13 g for a total of 10 cycles, one third of the total cycles in each component, X, Y, and Z.

Tcat Procedure:

The nvitch vac tested in eccl $ of three mutually perpendicular directions, designated X, Y, and Z, parallel to the major axcu of the nvitch.

In each orienLution, the fragility dwell tect and the plant induced vibration simulut,1on te st were made.

In the Fragility TMell test the switch contacts were monitored.

Ibth the I ormally Open (I:0) contacts and the Normally Closed (I;C) contacts were monitored for seismic failure by means of a light indicator circuit.

No seismic failure occurred during the tects.

The trip angle of the switch was alco monitored during the test at both the normally Op?n (1:0) contacts and the llormally Closed (11C) contacts.

The llorzaally Open (HO) contacts were monitored first.

The suitch was actuated and subjected to vibration for a minimu:n of 30 ceconds.

I! ext, the I!ormally Closed (I!C) contacts verc monitored with the switch unactuated and cubjected to vibration for a minimma of 30 acconds. Total vibration time uns a minimun of 60 seco. ids.

('))

This procedure van repeated for each frequency of the fragility dwell tect..

The trip pocition remained within 1/16 inch throughout the tent proccdure uit.h the follouing three exceptions:
