FUNCTION .BR ------------- .SKIP 2 THE PURPOSE OF THE REMOTE CONSOLE IS TO: .LIST .INDENT -2 *#HOUSE THE COUNTER/PRINTER SUBSYSTEM .SKIP .INDENT -2 *#PROVIDE THE ELECTRONIC CIRCUITY (DEC K SERIES) NECESSARY TO RECEIVE AND FORMAT DEFECTIVE FOOT ZONE FOR THE THREE LANE PRINTERS .SKIP .INDENT -2 *#RECEIVE WINDUP SIGNALS SUCH AS WEB FOOT PULSES AND DOFF-KNIFE RELAY CLOSURES; THEN TRANSMIT THEM TO OTHER LOCATIONS (E.G. MAIN CONSOLE OR ALARM LIGHTS). .SKIP .INDENT -2 *#PROVIDE THE OPERATOR WITH CERTAIN CONTROLS .SKIP .INDENT -2 *#PROVIDE AN INTERFACE FOR THE EDGE TEAR RELAYS .SKIP 2 .END LIST
.PAGE C. DESCRIPTION .BR ---------------- .SKIP 2 C.1 DEFECT LOGIC .BR --------------------- .SKIP 2 THE FUNCTION OF THE DEFECT LOGIC CIRCUITS IS TO: .SKIP .LIST .INDENT -2 *#CONVERT FOOT PULSES TO YARD PULSES .SKIP .INDENT -2 *#INCREMENT YARDAGE COUNTER .SKIP .INDENT -2 *#COUNT NUMBER OF DFZ'S IN EACH YARD .SKIP .INDENT -2 *#PROVIDE MEMORY TO STORE DFZ COUNTS FOR 8 YARDS. (DISTANCE FROM WINDUP TO SCANNER) .SKIP .INDENT -2 *#CONVERT DFZ COUNT FROM BINARY TO DECIMAL .SKIP .INDENT -2 *#ISSUE COMMANDS TO THE DIGITEC PRINTERS TO PRINT DFZ COUNT AND ASSOCIATED YARDAGE .SKIP 2 .END LIST FIGURE 36 SHOWS THE BASIC FLOW OF DEFECT INFORMATION FROM ONE LANE IN THE MAIN CONSOLE TO THE DATA AND PRINT COMMAND OF PRINTER NO. 1 IN THE REMOTE CONSOLE. FOOT PULSES, GENERATED BY THE WINDUP TACHOMETER GENERATOR, SYCHRONIZE ALL OF THIS DATA TRANSMISSION. .SKIP AT THE COMPLETION OF EACH FOOT PULSE THE DFZ BUFFER IS RESET, IF IT HAS BEEN SET, A 1 MSEC. STANDARDIZED PULSE IS SENT TO THE DFZ COUNTER IN THE REMOTE CONSOLE. AT THE COMPLETION OF THREE FOOT PULSES THE FOOT TO YARD (DIVIDE BY THREE) PULSE CONVERTER INITIATES A SERIES OF PULSES THAT: .LIST .INDENT -2 *#INCREMENT THE YARDAGE COUNTER .SKIP .INDENT -2 *#SHIFT THE COUNT IN THE DFZ COUNTER INTO THE 8 BIT DEFECTIVE YARD ZONE MEMORY .SKIP .INDENT -2 *#RESET THE DFZ COUNTER .SKIP .INDENT -2 *#READ THE MEMORY TO DETERMINE IF A DEFECTIVE YARD ZONE PULSE SHOULD BE GENERATED .SKIP .END LIST
.PAGE .CENTER FIGURE 36 LANE LOGIC AND REMOTE CONSOLE .BLANK .PAGE IF A DFZ COUNT WAS STORED IN MEMORY 8 YARDS EARLIER, THE DFZ COUNT IS CONVERTED FROM BINARY TO DECIMAL AND ALONG WITH A PRINT COMMAND PRESENTED TO THE DIGITEC PRINTERS. .SKIP 2
C.2 DOFF AND PRINTER LOGIC .BR --------------------------------- .SKIP 2 CERTAIN FUNCTIONS MUST BE SYNCHRONIZED WITH THE END OF ONE MILL ROLL AND THE BEGINNING OF THE NEXT. LOGIC WITHIN THE DEC RACK AND THE DIGITEC PRINTER SUBASSEMBLY ACCOMPLISH THIS. .SKIP REFERRING TO DRAWING M711, THE DOFF-KNIFE RELAY IS NORMALLY OPEN. ASSUMING THE DIGITEC PRINTER SYSTEM IS IN THE "AUTOMATIC" MODE (SEE SECTION C.3.2 OF THE DIGITEC MANUAL), THE FOLLOWING SEQUENCE OF EVENTS WILL OCCUR WHEN THE DOFF KNIFE FIRES: .LIST .INDENT -2 *#THE DOFF KNIFE RELAY WILL CLOSE FOR APPROXIMATELY 1/2 SEC. .SKIP .INDENT -2 *#DEC LOGIC MODULE A32 SENSES THIS CLOSURE AND MODULE A24 CONVERTS THE CLOSURE INTO A 1 MSEC. PULSE, WHICH IS SENT TO A STRING OF DELAYS ON MODULE A23 AND TO EACH OF THE THREE PRINT COMMAND ONE SHOTS ON MODULE A18 .SKIP .INDENT -2 *#THE THREE PRINTERS WILL IMMEDIATELY PRINT THE TOTAL NUMBER OF YARDS ON THE MILL ROLL JUST COMPLETED .SKIP .INDENT -2 *#AT 350 MSEC. AFTER THE DOFF SIGNAL IS RECEIVED, MODULE A23E TRIGGERS A23L, WHICH GOES ON FOR 1 SEC. .SKIP .INDENT -2 *#THIS 1 SEC. PULSE IS APPLIED TO THE DIGITEC PRINTER SYSTEM'S "HOLD OFF AND ADVANCE SPACE" TERMINAL TB1-15, WHICH PREVENTS ANY PRINTING AND CAUSES THE THREE PRINTERS TO ADVANCE THEIR PAPER BY 2 OR 3 SPACES .SKIP .INDENT -2 *#AT THE END OF THE 1 SEC. PERIOD, MODULE A23E GOES ON FOR 100 MSEC. AND CAUSES THE FOLLOWING SEQUENCE OF EVENTS TO OCCUR: .LIST .INDENT -2 *#THE MILL ROLL ID COUNTER IS INCREMENTED .SKIP .INDENT -2 *#THE NEW MILL ROLL NUMBER IS PRINTED ALONG WITH AN UP ARROW ON ALL PRINTERS. (THIS IS CALLED FORMAT A; THE SYMBOL ALERTS THE OPERATOR THAT THIS IS A MILL ROLL, NOT A DEFECTIVE YARD NUMBER .SKIP .INDENT -2 *#THE DIGITEC YARD COUNTER IS RESET TO ZERO .SKIP .INDENT -2 *#THE LOGIC TO ACCOMPLISH THIS SEQUENCE IS CONTAINED IN THE DIGITEC SUBASSEMBLY .END LIST .END LIST

CONTROLS NECESSARY TO OPERATE THE SYSTEM WILL BE COVERED NEXT. .SKIP 2 C.4 OPERATOR'S CONTROLS .BR -------------------------- .SKIP 2 IN ADDITION TO THE PRINTER SYSTEM CONTROLS, THE REMOTE CONSOLE HAS ILLUMINATED PUSHBUTTONS ON THE FRONT PANEL OF THE CONSOLE; 3 TOGGLE "DISABLE SWITCHES" MOUNTED ON AN INSIDE REAR PANEL AND 1 TOGGLE SWITCH FOR SIMULATED FOOT PULSES. .SKIP 2 C.5 FRONT PANEL PUSHBUTTONS .BR ---------------------------------- .SKIP 2 .LIST .INDENT -2 *#"CONSOLE" POWER: ALTERNATE ACTION, ON-OFF .SKIP .INDENT -2 *#"EDGE TEAR" POWER: ALTERNATE ACTION, ON-OFF .SKIP .INDENT -2 *#"ALARM ACKNOWLEDGE": LIGHTS WHEN DOFF ALARM OCCURS; PRESS TO SILENCE DOFF ALARM AND RESET MAIN CONSOLE ALARM DOFF INDICATORS .SKIP .INDENT -2 *#"AUTO DOFF RESET": LIGHTS TO INDICATE THAT ONE ALARM HAS OCCURED AND NO MORE WILL BE PERMITTED UNTIL THIS PUSHBUTTON IS DEPRESSED .SKIP .INDENT -2 *#"MEMORY CLEAR": PRESSING CLEARS ALL DEFECT INFORMATION STORED IN THE 8 YARD DEFECTIVE YARD ZONE MEMORY. SINCE ACCIDENTAL ACTUATION WOULD CLEAR OUT DEFECT DATA THAT MIGHT BE IMPORTANT THIS SWITCH IS PROTECTED BY A CLEAR HINGED COVER. THE SWITCH IS USEFUL DURING STARTUP OF THE REMOTE CONSOLE WHEN UNKNOWN OR UNWANTED DATA MAY BE IN MEMORY. .SKIP .END LIST
.PAGE C.6 COUNTER PRINTER SUBASSEMBLY CONTROLS .BR --------------------------------------------- .SKIP 2 REFERENCE: FIGURE 38 .SKIP 2 C.7 YARD AND ID COUNTER MODULE .BR ------------------------------------- .SKIP 2 THE PURPOSE OF THE FOUR ILLUMINATED PUSHBUTTONS ASSOCIATED WITH THE YARD AND COUNTER MODULE IS AS FOLLOWS: .LIST .INDENT -2 *#"POWER": ALTERNATE ACTION, CONTROLS AC POWER TO ALL UNITS, PROVIDED THE CONSOLE POWER SWITCH IS "ON" .SKIP .INDENT -2 *#"MANUAL": THE MANUAL MODE IS PROVIDED TO ENABLE FRONT PANEL OPERATION OF THE THREE PRINTERS AND THE MANUAL "RESET" OF THE YARD COUNTER. THIS MODE DISABLES ALL INPUTS FROM THE INSPECTOR LOGIC. .END LIST .NOTE NOTE THE PRINTER SYSTEM MUST NEVER BE IN THE MANUAL MODE WHEN INSPECTING PRODUCT, UNLESS NO RECORD OF THE INSPECTION IS DESIRED. .END NOTE .LIST .INDENT -2 *#"RESET": MOMENTARY PRESSING RESETS YARD COUNTER TO ZERO. (TO RESET THE ID COUNTER ONE MUST REPETITIVELY DEPRESS THE BAR UNDER EACH DIGIT OF THE COUNTER.) .SKIP .INDENT -2 *#"AUTO": PRESSING THIS PUSHBUTTON PUT THE SYSTEM IN THE AUTOMATIC MODE. EACH TIME THE SYSTEM IS CHANGED FROM MANUAL TO AUTOMATIC THE FOLLOWING SEQUENCE WILL OCCUR: .LIST .INDENT -2 1.THE MILL ROLL ID NUMBER WILL BE PRINTED ON ALL THREE PRINTERS ALONG WITH AN UP ARROW .SKIP .INDENT -2 2.THE YARDAGE COUNTER IS RESET TO ZERO .SKIP .INDENT -2 3.THE ID COUNTER WILL INCREMENT BY ONE .END LIST .END LIST
