B. 'EOS' AND 'LLE'
.BR
-----------------
.SKIP 2
REFERENCE: 2147M734
.SKIP 2
THE FUNCTION OF THE 'EOS' AND 'LLE' IS TO SYNCRONIZE THE TIMING
AND GATE GENERATION CIRCUITS IN THE CHANNEL DRAWER WITH THE 
SCANNER. THE 'LLE' SETS THE 'INSPECTION PERIOD ENABLE' (IPE)
FLIP-FLOP. THE 'EOS' STARTS A SEQUENCE OF EVENTS THAT GENERATE
THE 'PRODUCT GATE' AND RESET THE 'IPE' FLIP-FLOP. THE TIMING
RELATIONSHIP OF THESE PULSES TO THE 'TEST DEFECT' PORTION OF
THE 'COMPOSITE PA' IS ESTABLISHED BY ADJUSTING ONE SHOT C7T2
AND C8T2. WHEN SETTING UP THESE ONE SHOTS THE PEDESTAL PORTION
OF THE 'COMPOSITE PA' MUST BE APPROXIMATELY 455 USEC.
(MAXIMUN WIDTH PRODUCT). THE PROCEDURE FOR SETTING THESE TIMING
RELATIONSHIPS IS:
.SKIP
.NOTE
POTENTIOMETER LOCATION
THERE ARE TWO CIRCUITS ON THE M302 AND M3020 ONE SHOT MODULES.
LOOKING FROM THE COMPONENT SIDE OF THE MODULE THE LEFT
POTENTIOMETER CONTROLS THE T2 OUTPUT. THE RIGHT POTENTIOMETER
CONTROLS THE F2 OUTPUT.
.END NOTE
DISPLAY THE 'COMPOSITE PA' ON ONE TRACE OF A DUAL TRACE SCOPE
.SKIP
DISPLAY THE OUTPUT C6F2 AND ADJUST TO BE APPROXIMATELY 500 USEC.
THIS SIGNAL DISABLES NAND GATE D15V2 AND INHIBITS THE PEDESTAL 
COMPONENT OF THE 'COMPOSITE PA' FROM TRIGGERING ONE SHOTS
C7 AND C8
.SKIP
DISPLAY THE 'LLE' ON THE SCOPE AND ADJUST C8F2 TO BE APPROXIMATELY
1 USEC.
.SKIP
ADJUST C8T2 TO POSITION THE 'LLE' JUST BEFORE THE LEADING EDGE
OF THE PEDESTAL PORTION OF THE 'COMPOSITE PA'. APPROXIMATELY
11.5 USEC. FROM THE 'TEST DEFECT' PORTION OF THE 'COMPOSITE PA'
.SKIP
DISPLAY THE 'EOS' ON THE SCOPE AND ADJUST C7F2 TO BE APPROXIMATELY
1 USEC.
.SKIP
ADJUST C7T2 TO POSITION THE 'EOS' AFTER THE TRAILING EDGE OF THE
PEDESTAL PORTION OF THE 'COMPOSITE PA'
.PAGE
C. SYNC
.BR
-------
.SKIP 2
REFERENCE: 2147M734
.SKIP 2
THE SYNC TEST JACK PROVIDES A SIGNAL TO SYNCRONIZE AN OSCILOSCOPE
TO THE SCANNER. ONE PULSE IS GENERATED FOR EVERY EIGHT SCANS.
THIS PERMITS VEIWING THE SCANS ONE AT A TIME ON A SCOPE.
.SKIP
THE 'LLE' PULSES ARE USED TO DEVELOP THIS SIGNAL. THE OUTPUT OF 
A DIVIDE BY EIGHT COUNTER IS THE SYNC SIGNAL.
.SKIP 2
D. CLOCK/10
.BR
-----------
.SKIP 2
REFERENCE: 2147M734
.SKIP 2
FOR CONVENIENT REFERENCE DURING CHECK AND TESTING THE 3.346 MHZ
CLOCK SIGNAL IS DIVIDED BY 10. THIS SIGNAL IS ENABLED BY THE 'IPE'
AND AVAILABLE AT A TEST JACK ON THE FRONT PANEL.
.SKIP 2
E. TEST DEFECT GATE AND PRODUCT GATE
.BR
------------------------------------
.SKIP 2
REFERENCE: 2147M733, 2147M734
.SKIP 2
THE FUNCTION OF THESE CIRCUITS IS TO GENERATE THE 'TEST DEFECT GATE'
AND THE PRODUCT GATE'. BECAUSE THE 'PROCUCT GATE' CAN VARY DUE TO
PRODUCT WIDTH, THE PEDESTAL IS MEASURED EACH SCAN. THE FOLLOWING
SCANS 'PRODUCT GATE' IS BASED ON THAT MEASUREMENT. THE TECHNIQUE
FOR MEASURING THE PEDESTAL WIDTH IS TO COUNT CLOCK PULES DURING
THE PEDESTAL IN AN UP COUNTER. THIS COUNT REPRESENTS THE PEDESTAL
WIDTH AND IS USED TO GENERATE THE 'PRODUCT GATE'. THIS IS DONE BY
LOADING THE NUMBER IN THE UP COUNTER INTO A DOWN COUNTER AND
COUNTING DOWN DURING THE PEDESTAL. AS THE APPROPRIATE NUMBERS ARE 
DECODED THEY ARE USED TO GENERATE THE 'PRODUCT GATE'.
.SKIP
THE 'TEST DEFECT GATE' DOES NOT VARY AND CAN BE GENERATED WITH
JUST THE UP COUNTER AND APPROPRIATE DECODES. THE ACTIVITY OF THE 
UP AND DOWN COUNTERS IS SYNCRONIZED TO THE 'COMPOSITE PA' BY 
A FLIP-FLOP SEQUENCER.
.SKIP
THE FOLLING PROCEDURE IS USED TO VERIFY THESE CIRCUITS:
.SKIP
CONNECT THE 'COMPOSITE PA' TO ONE TRACE OF A DUAL TRACE SCOPE
.SKIP
CONNECT THE OTHER TRACE TO C18-H2, THE 'TEST DEFECT GATE'
.SKIP
THIS SIGNAL SHOULD BE WITHIN THE TEST DEFECT PORTION OF THE
'COMPOSITE PA'
.SKIP
DISPLAY THE SIGNAL FROM THE 'PRODUCT GATE' TEST JACK
.SKIP
THIS SIGNAL SHOULD BE WITHIN THE PEDESTAL PORTION OF THE
'COMPOSITE PA'
.SKIP
VARY THE WIDTH OF THE PEDESTAL AT THE SIMULATOR. THE 'PRODUCT GATE'
SHOULD FOLLOW THE PEDESTAL
.SKIP 2
F. ALARMS
.BR
---------
.SKIP 2
REFERENCE: 2147M736
.SKIP 2
THERE ARE SIX ALARM CIRCUITS IN THE TRANSMISSION CHANNEL DRAWER.
THESE CIRCUITS CONSIST OF AN R-S FLIP-FLOP AND FOUR LAMP DIRVERS.
SINCE THE INDICATORS FOR THESES CIRCUITS ARE NOT IN THE CHANNEL 
DRAWER, THE BEST TIME TO VERIFY THESE CIRCUITS IS WHEN THE 
CHANNEL DRAWER IS IN THE MAIN CONSOLE.
.SKIP
FORCING THE SET INPUT OF THE FLIP-FLOP TO GROUND CAUSES THE 
ASSOCIATED INDICATORS TO LIGHT. PRESSING ANY OF THE SIX
INDICATORS RESETS ALL FLIP-FLOPS.
.SKIP 2
G. LANE GATE CIRCUITS
.BR
----------------------
.SKIP 2
REFERENCE: 2147M735
.SKIP 2
THE LANE BOUNDRY SWITCHES SET UP ELECTRONIC LANES THAT CORRESPOND
TO THE SLIT WIDTH OF THE ACTUAL PRODUCT. THE SEQUENCE OF EVENTS
THAT GENERATE THE LANE GATES IS:
.SKIP 2
THE 'EOS' INITIATES THE CONVERT SIGNAL TO MODULES AB2 AND AB3.
THESE MODULES CONVERT THE BCD NUMBER IN THE LANE BOUNDRY
SWITCHES TO BINARY. THE 'EOS' ALSO RESETS THE 'IPE' AND ZEROES
THE LANE COUNTER.
.SKIP
THE 'LLE' SETS THE 'IPE' AND ENABLES THE LANE COUNTER TO START
COUNTING CLOCK PULSES.
.SKIP 
THE LEADING EDGE OF THE 'PRODUCT GATE' STARTS LANE 1.
.SKIP
WHEN THE COUNT IN THE LANE COUNTER EQUALS THE NUMBER SET IN THE
LANE 1-2 BOUNDRY SWITCH COMPARATOR 1 GENERATES A PULSE THAT RESETS
LANE 1 AND SETS LANE 2.
.SKIP
WHEN THE COUNT IN THE LANE COUNTER EQUALS THE NUMBER SET IN THE
LANE 2-3 BOUNDRY SWITCH COMPARATOR 2 GENERATES A PULSE THAT RESETS
LANE 2 AND SETS LANE 3.
.SKIP
THIS SEQUENCE IS REPEATED FOR EACH 'EOS' PULSE.
.SKIP 2
THE PROCEDURE FOR VERIFYING THESE CIRCUITS IS:
.SKIP 2
CONNECT SCOPE TO B14U2 AND SET THE LANE 2-3 BOUNDRY AS CLOSE AS
POSSIBLE TO THE TRAILING EDGE OF THE 'PRODUCT GATE'.
.SKIP
CONNECT THE SCOPE TO B14J2 AND SET THE LANE 1-2 BOUNDRY AS CLOSE
AS POSSIBLE TO THE LEADING EDGE OF THE 'PRODUCT GATE'.
.SKIP
INCREMENT THE LANE 1-2 BOUNDRY SWITCH AND OBSERVE THAT THE SIGNAL
MOVES THE APPROPRIATE NUMBER OF CLOCK PULSES.
.SKIP
RETURN THE LANE 1-2 BOUNDRY AS CLOSE AS POSSIBLE TO THE LEADING
EDGE OF THE 'PRODUCT GATE'.
.SKIP
CONNECT THE SCOPE TO B14U2 AND DECREMENT THE LANE 2-3 BOUNDRY
SWITCH AND OBSERVE THAT THE SIGNAL MOVES THE APPROPRIATE NUMBER 
OF CLOCK PULSES.
.SKIP
SET THE LANE BOUNDRY SWITCHES TO DIVIDE THE PEDESTAL INTO APPROXIMATE
THIRDS FOR REMAINING CHECKOUT.
.SKIP
CONNECT THE SCOPE TO B14P2 AND CHECK FOR PRESENCE OF LANE 2 GATE.
.SKIP

H. PRODUCT SELECT SWITCH
.BR
------------------------
.SKIP 2
REFERENCE: 2147M735
.SKIP 2
THE PRODUCT SELECT SWITCH IS A FIVE POSITION PUSHBUTTON SWITCH
EACH POSITION CONSIST OF FOUR SPST SWITCHES. FOUR OF THESE POSITIONS
PROVIDE LOGIC LEVELS FOR THE CLASSIFICATION OF DEFECTS INTO EITHER
THE MAJOR OR CRITICAL CATEGORY. THE REMAINING POSITION PERMITS THE
COMPUTER TO PROVIDE THE SIGNALS FOR CLASSIFICATION. THE SYSTEM
HAS THE ABILITY TO CLASSIFY FOUR TYPES OF DEFECTS INTO EITHER THE
MAJOR OR CRITICAL CATEGORY. SINCE ALL FOUR CIRCUITS ARE SIMILIAR
IN OPERATION ONLY THE + TRANSMISSION DEFECT SIGNALS WILL BE 
DESCRIBED IN DETAIL.
.SKIP
THE + TRANSMISSION DEFECTS ARE FED TO  NAND GATES A5C1 AND A5F1.
IF A5C1 IS ENABLED THE DEFECT IS CLASSIFIED AS MAJOR AND "ORED"
TOGETHER IN NOR GATE A6E1 WITH ANY OTHER MAJOR DEFECTS. NAND GATE
A5C1 CAN BE ENABLED BY EITHER THE PRODUCT SELECT SWITCH OR THE 
COMPUTER. WHEN THE "PE" PUSHBUTTON IS DEPRESSED A GROUND LEVEL IS
APPLIED TO ONE INPUT OF NOR GATE A4K2, THIS ENABLES NAND GATE A5C1.
WHEN THE COMPUTER PUSHBUTTON IS DEPRESSED THE OPTICAL ISOLATOR
B23U1 IS ENABLED. IF THE MERGE CURRENTLY SELECTED BY THE COMPUTER
IS ONE OF THE "PE" MERGES THEN A LOW LOGIC LEVEL WILL BE ON THE 
OTHER INPUT OF NOR GATE A4K2. THIS PERMITS THE COMPUTER TO ENABLE
A5C1.
.SKIP
ALL OPTICAL ISOLATOR OUTPUTS ARE DISABLED IF NOT IN THE COMPUTER
MODE. WHEN THESE OUTPUTS ARE DISABLED THEY ARE AT A LOGIC HIGH.
.SKIP
VERIFY THE OPERATION OF THE PRODUCT SELECT SWITCH BY DEPRESSING
EACH POSITION AND CHECKING FOR PROPER LEVELS IN THE ASSOCIATED 
CIRCUITRY. THE FOLLOWING CHART SHOWS WHICH DEFECTS ARE CLASSIFIED
AS MAJOR AND CRITICAL FOR EACH PRODUCT TYPE.
