DEATH ON CONTACT OR SEVERE BURNS

may result if safety precautions are not observed .

Never work on electronic equipment unless there is someone nearby who is familiar with the operation and hazards of the equipment and who is able to give first aid . When the technician is aided by operators , he must warn them about dangerous areas . When possible , shut off power to equipment . Remove all jewelry from hands and wrists before beginning work on the equipment .

Be careful not to contact high - current connections when installing or operating this equipment . When possible , keep one hand away from the equipment to reduce hazard of current flowing through the vital organs of the body.

TM 9-1430-600-20-1

INSTRUCTIONS FOR ARTIFICIAL RESPIRATION (Extracted (with modifications ) from FM 21-11 , First Aid for Soldiers)

a.

Take a deep breath ,

open your mouth wide ,

and

make

an

airtight seal around the

casualty's nose , using one of the techniques shown in the figure .

b.

With your eyes focused on the casualty's chest , blow forcefully into the airway ( mouth or nose). Rising of the casualty's chest indicates that the air is reaching the lungs . In this case , the procedure is continued . If the chest does not rise , corrective action must be taken. First , hold the jaw up more forcefully and blow harder , making sure that the air is not leaking from the mouth or nose . If the chest still does not rise , recheck the mouth for foreign matter. If necessary, turn the casualty on one side . Strike the casualty between the shoulders with considerable force , repeatedly if necessary , to dislodge obstruction in the airway; then resume attempts to inflate lungs .

C.

Remove your mouth from the casualty's airway opening and listen for the return of air . If the casualty's exhalation is noisy , elevate the jaw more .

d.

After each exhalation of air from the casualty's lungs , blow another deep breath into the airway. Make the first five to ten breaths deep and give them at a rapid rate in order to provide fast reoxygenation . Thereafter , give the breaths at a rate of 12 to 20 per minute until the casualty is able to breathe satisfactorily or until you are positive life is gone . A smooth rhythm is desired but split- second timing is not essential . As the casualty attempts to breathe , adjust the timing of your efforts to assist .

WARNING

After a period of resuscitation , the casualty's abdomen may bulge indicating that some of the air is going into the stomach . Since inflation of the stomach makes it more difficult to inflate the lungs, apply gentle pressure to the abdomen with your hand between inflations . If your breathing at the start has been very deep and rapid , you may become faint , tingle , or even lose consciousness if you persist. After administering the first five to ten deep , rapid breaths , you should adjust your breathing to a rate of 12 to 20 times a minute , with only moderate increase in normal volume so that you will be able to continue to give artificial respiration for a long period without temporary ill effects .

WARNING

RADIO - FREQUENCY RADIATION HAZARD

Radio- frequency (rf) radiation from radar set ( RS ) antennas and associated equipment is not cumulative , but it can be hazardous . It heats the body tissues , and , if the radiation intensity is sufficiently high , will permanently damage tissue . This damage is not immediately apparent .

SAFETY PRECAUTIONS Observing the following precautions will insure that no one is exposed to hazardous levels of rf radiation . Stay out of the area within 120 meters in front of RS and within maximum angular track limits . Stay at least two meters from sides of the RS. Stay out of buildings , shelters , and vehicles between RS and denied occupancy zone .

Stay offthe roof and ladder of RS. Stay out of the door - platform area of RS . Operational personnel shall conduct routine functional tests of all warning devices and interlock systems and maintain a log book of all such tests .

Give audible signals to alert personnel that RS is going on the air. •

Conduct initial and routine briefings on system hazards and the radiation protection program for all site personnel . Stop RS radiating immediately when a fixed beam condition such as clutter or target dropout is indicated .

Before radiating or going to remote operation insure that all crew members have vacated the RS roof and area .

Place a placard at the fire control operator console indicating the prohibited azimuths , computer tapes , and power levels for each primary target line and secondary target line .

FAULT INDICATOR TABLE The fault indicator table is used when the operator at the display and control (D & C)

console observes a fault indication on an indicator panel . The corrective procedure referenced in the table is then performed . Most of the faults listed indicate a power control or interlock

AN hardware failure . These types of faults will register on one or more of the indicator panels listed .

SATR Since these faults result in one or more subsystems being inoperative , the operator should look at all panel fault indications to determine which procedure to perform . The operator should observe the following rules to determine which procedure to perform first:

1.

For Crash -Type Prime Power Failures : Generator Control Panel A64 and Distribution Box A66 corrective procedures should be performed first.

2. For Control and Interlock Failures : Distribution Box A66 and Ambient Air Control Panel A72 corrective procedures should be performed first . 3. For Non-Crash -Type Computer and Display Failures : BITE Indicator Panel A51 corrective procedures should be performed first .

Before starting the corrective procedure referenced in the table , the operator NOTE

should check for open drawers , open blackout curtains , or any other nonstandard operating condition .

ARRAYS A 150

The antenna map is a computer printout showing antenna element test

results in a special format .

The Antenna Group A 150 on the radar set has seven arrays ; the main array, track - viamissile (TVM ) array, and five side lobe canceller ( SLC ) arrays . The arrays consist of individual phase shifting radar elements - 5463 active and 204 unused . The antenna element test uses a computer and 212 BITE lines to insure these elements are working properly. Each element is 337.5 degree tested and , simultaneously , each BITE line is zero degree tested . The results generated are sent from the beam steering processor ( BSP) to the control unit group input output control ( CUGIOC) in the form of 312 24- bit words. A reformatting program is used to change this data into a more useful form . This program analyzes the 312 words and produces a pass /fail score for each element and BITE line . These results are printed in a standard format which represents the front views of the seven arrays. Each of the 5667 elements has a character print position representing its actual location in its particular array. The element's test result is printed in its assigned position with an asterisk ( * ) for pass and a character (0) for fail . The BITE line scores are printed the same way under the heading ZERO TEST . This output from the hard copy unit ( HCU ) is called the antenna map (fig . A and fig . B) .

Purpose. The purpose of the antenna map is: (1 ) To visually display the location of those elements in the main array, TVM array, and

SLC- 5 array that have failed their 337.5 degree test , (2)

To display the results of the zero degree BITE Line test,

(3) To provide the means for detecting at least three types of antenna faults :

6 (a)

Defective beam steering shift registers ( BSSR) module output buffers (24 per

(b)

Defective row /column driver ( RCDR) module input buffers (30 per module) ,

module),

RACK

VIA SSILE RRAY 50A2

(c) Defective beam steering control module ( BSCM ) ( 36 input line receivers per module), and (4)

To provide verification of failed battery replaceable units ( BRUS ) reported in

dynamic tests , such as :

VE) 150

c.

(a)

Output storage and timing module (OSTM) zero degree test BSP070 ,

(b)

OSTM 337.5 degree test BSP070,

(c)

Power supply failures BSP040-002 , and

(d)

RCDR failures BSP040-002 .

Antenna Map .

(1 )

Printout. The antenna map arrays use 133 character print positions to display

their data . The HCU can only print 80 character positions so the map is divided into sections . These sections must be assembled to create an entire antenna array. To assemble , the five sheets (fig . B) marked main array left side must be overlapped by the five sections marked main

al array right side . The columns will overlap near the center of the array . Rows do not overlap and

1 have to be positioned in proper order to present a correct map . The TVM and SLC (fig . C and D) arrays are each printed on two sheets which also have to be assembled . The referenced figures show how the completed maps should appear.

(2)

Antenna Quadrants .

The main array antenna map shows 5161 element locations .

It is divided into four sections ( fig . E ) ; Quad 1 ( upper left) , Quad 2 ( upper right) , Quad 3 (lower right), and Quad 4 (lower left) . (3)

Antenna Rows .

There are 149 element rows arranged horizontally and identified

by numbers to the left and right of the element locations . The rows in Quads 1 and 2 run from +74to 0. The rows in Quads 3 and 4 run from 1 to -74. (4)

Antenna Columns .

There are 85 element columns arranged vertically and

identified by numbers at the top and bottom of the element locations . The columns in Quads 1 and 4 run from -42 to 0. The columns in Quads 2 and 3 run from +1 to +42.

Diagnostic Delimiters . The antenna map can be used to fault isolate BRUS (7) including power supplies , BSSR , RCDR , and BSCM modules . This is done with diagnostic delimiters (fig . G ) , which are markings at the extreme left , right , top , and bottom of the map . The delimiters indicate which BRUS control a particular row or column of elements . By examining fault patterns , malfunctioning modules can be isolated . Note the area between delimiters for BSCM and RCDR modules .

Antenna Map Fault Patterns .

The antenna map printout is used for identifying diagnostic fault indications . Using (1 ) infor mation provided by the antenna map , you may localize the specific fault condition . By the matching the antenna map printout with the examples given in the following paragraphs , the fault can be classified . Once classified , proper corrective action may be taken . Fault patterns resulting from RCDR , BSCM , and BSSR module failures may consist (2 ) of strings of zeros appearing in any row , column , or zero degree test column controlled by that module . Row Buffer failure fault . The BSSRs generate phase setting control for the (a) elements and deliver the start column / stop row pulses to the RCDR modules . Those modules drive up to 75 elements per column and up to 43 elements per row . None of the dynamic BSP tests monitor the operation of the BSSR output buffers or the RCDR input buffers . Failure of one of these devices can be detected only by operator fault pattern recognition of the antenna map printout . An example of a faulty buffer is shown in figure J. Notice the series of 19 zeros across Row-68 of the main array.

Column Buffer failure fault (BSSR or RCDR) .

When a column buffer failure

occurs at BSSR or RCDR buffers , the antenna map will display one of two types of patterns. An example of the first type of pattern is shown in fig . K. Notice that column -42 contains all fail

9

indications (0) from row 20 to row -20 , (with the exception of the element in row 10; this will be discussed under multiple resetting elements) . This type of pattern occurs for a 337.5 degree test. (c)

Column Buffer failure fault (ZERO TEST) .

An example of the second type of

st pattern displaying a column buffer failure is shown on figure L. The string of fault indications (0) in the ZERO TEST column start at row 67 , quadrant 1 , and extends to row -68 in quadrant 4. The fault could be any of the column RCDR or BSSR modules that service quadrants 1 and 4. To isolate this problem , use table A along with the map . In the table under the heading of ZERO TEST FAULT PATTERN , find the condition or pattern that exists on the map . If a string of fail indications appeared in the ZERO TEST column for quadrants 2 and 4 , the same method would apply, using table B. Tables C and D are used for the TVM and SLC- 5 antenna arrays , respectively.

Multiple resetting element fault.

Leaky capacitors in the antenna elements

cause the elements to produce more than one BITE response pulse . There should be only one

429 BITE response pulse produced per element during the reset time period . This is known as a BITE response and should only be present at specific times in a certain time frame (window) . When a

87654320

BITE pulse is sensed within the window at the wrong time , as is the case with a multiple resetting element , it causes two consecutive fail indications (0) in the ZERO TEST column of the map. Figure F illustrates this condition to the two consecutive zeros in the top row of each array

tti

which will show only one zero . When any of the 43 elements in this BITE line becomes a multiple resetter, it causes its BITE line to fail the ZERO TEST as indicated by the zeros . Isolation to a

ttt!

ttt ttt tit tt ttt

faulty multiple resetter requires a special fault location procedure . This procedure is contained in para 3-13. (4)

Deenergized or faulty contactor or tripped circuit breaker fault.

This is

caused by either a deenergized antenna electronics contactor 2K2 or a tripped circuit breaker 2A30CB93 . The contactor and circuit breaker mutually supply the antenna 12.66 -Volt power supplies with three phase power. All element positions in the three arrays will show fault conditions (0). (5) (a)

Element input loading or backplane wiring fault. Whenever a single row or column exhibits a 337.5 degree failure pattern such as

illustrated in figure I , another failure , other than a buffer problem , has been experienced . The fault can be a backplane wiring short circuit or an element row or column loading problem . The backplane wiring problem is beyond the maintenance scope of the operator and organizational maintenance personnel . The element loading problem , however , can be detected by the divideby-two principle of unseating elements . This action should not be undertaken until the row or column buffer fault localization procedure has failed to solve the problem . TABLE A.

IX TION

(b) Because of a possible faulty logic IC on an element or a wiring resistive short on the backplane , the row or column reporting information can be distorted enough to fault a row or column without loading down the RCDR module . Ambient temperature effects on logic thresholds can sometimes change fault patterns . This condition is illustrated on figure M. The figure shows a segment of the map (rows - 27 through -34) run at different times of the day andillustrates the temperature variable . The actual problem here is a backplane wiring short . However , if the problem was caused by a faulty element, the method of fault locating is given in para 3-10.

(6)

5-Volt Power Supply Fault Verification . When a 5 - volt power supply fails in any

of the antenna arrays , the antenna map failure may be used to correlate the fault reported in BSP- 040-002 . The ZERO TEST column for the area of elements supplied five (5) volts by the particular power supply . Figure N illustrates this condition . In this case , Power Supply PS1 , controlled by circuit breaker CB 17 , is faulty . Notice the series of zeros (0) in the ZERO TEST column for the area of coverage of PS1 . The TVM array would show all 33 ZERO TEST positions as zeros (0) if power supply PS 19 failed since it is the only 5- volt power supply used for that array . Similarly , .if power supply PS 19 failed, the 17 ZERO TEST positions for SLC- 5 array would zero(0) al l show

BEAM STEERING PROCESSOR 070 OUTPUT STORAGE AND TIMING MODULE TEST

a.

When a beam steering processer (BSP) 070 test is run and the printout indicates an

output storage and timing module (OSTM) fault , make an additional verification before concluding the fault is the OSTM . It is unlikely that this module would be involved unless there was a total breakdown of this test. b.

Thirteen antenna elements and six BITE lines have been preselected to test the

functions of the OSTM not previously used . They also test the ability of the system to output row and column information and correctly report their status. c.

The BSP070 test has two parts . The first part tests the ability of the thirteen elements

to respond correctly to a 337.5 degree row and column command . The second part tests the ability of six BITE lines to report a fault . The data is compared to an expected return to determine a pass or fail condition . If a fail is indicated , procedure BPMP01 will be printed and the user will be directed to para 3-7 for fault isolation .
