1) CHECK PLASTIC COLLAR AND COUPLING BETWEEN GEAR BOX AND FEED MOTOR




PRINTER NOT PRINTING


1) NO AIR PRESSURE. CHECK FOR AIR LEAKS FROM REGULATOR TO BOTTLE. ( MD-0007 or MD-0018)
2) CHECK THROUGH BEAM SENSORS ARE WORKING, SAW WILL NOT CYCLE IF SENSORS ARE NOT WORKING.
3) PRESS FLUSH BUTTON, IF BUZZING SOUND OCCURS PRINT HEAD MAY HAVE DRY INK INSIDE. NEVER RUN PRINT HEAD OUT OF INK, EXPENSIVE CLEANING REQUIRED. TAGS: PRINTER PRINT HEAD




ELECTRIC DOOR LOCK NOT WORKING


EUCHNER LOCK (BLACK BOX) NEEDS REBUILD - SEE REPAIR SHEET HERE ACTUATOR IS WORN ( EK-0002) KLM LOCK (RED) DISASSEMBLE, CLEAN, USE WHITE LITHIUM GREASE, OTHERWISE ARE NON REPAIRABLE ( EK-0003) (KEEP DOOR LATCHED AT ALL TIMES, DO NOT PULL ON DOOR WHILE ELECTRIC LOCK IS ENGAGED, CAN CAUSE DAMAGE)




IRREGULAR LENGTHS +/- (SEEMS RANDOM)


WEBSAW:
1) CHECK THAT ROLLERS ARE CLEAN AND THE KNURLING COMES TO A SHARP POINT.
2) WEBSAW: CHECK THAT THE SPRING MOUNTING RODS ARE NOT BROKEN AND THE SPRING TENSION IS SET CORRECTLY CLICK HERE FOR TENSION INSTRUCTIONS 3) WEBSAW: CHECK THAT THERE IS NOT ANY PLAY IN THE FEED ROLLERS BY ROCKING IT LEFT TO RIGHT BY HAND. ROCKING MAY INDICATE BAD SPIDER COUPLINGS 4) WEBSAW: CHECK THAT THE CONVEYOR IDLE ROLLER BEARINGS ARE GOOD BY ROCKING THEM AGAINST THEIR BEARING AXIS. MAY BE REPLACED WITH ROLLERS FROM ELSEWHERE IN THE CONVEYOR. HEAVY DUTY LOWER ROLLERS ARE AVAILABLE XL-SAW: 1) CHECK THAT ROLLERS ARE CLEAN AND THE KNURLING COMES TO A SHARP POINT. 2) CHECK THAT UPPER ROLLER BEARINGS BY ROCKING THEM AGAINST THEIR BEARING AXIS 3) CHECK THAT FENCE BEARINGS ARE IN GOOD CONDITION, THAT THEY SPIN FREELY AND SMOOTHLY




ONLY MANUAL CUT WORKS


1) CHECK THAT THROUGH BEAM SENSORS ARE WORKING.




SCRAP CONVEYOR RUNS REVERSE (XL-SAW ONLY)


SEE PRINTABLE GUIDE HERE
1) CHECK CONNECTIONS AT VFD-2 (AC TECH) and WCR/ATR (SLIM LINE RELAYS) 2) CHECK VFD BY JUMPERING TERM 1 & 2, IF IT WORKS NORMALLY GOTO NEXT STEP. IF NOT, CALL FOR SUPPORT 3) REPLACE WCR & ATR RELAYS ( EF-0007)




MOTORS NOT RESPONDING (WEBSAW WITH PARKER AMPS ONLY)


1) CHECK THAT ALL AMPS HAVE LIGHT OF SOME SORT. IF THERE IS POWER GOING TO THE AMP AND THERE ARE NO LEDS, THE AMP IS DEAD. USING A HEAT GUN TO GENTLY APPLY HEAT CAN MAKE A FAULTY AMP COME ON. THIS IS A TEMPORARY WORK AROUND UNTIL THE AMP CAN BE REPAIRED OR REPLACED. 2) CHECK THAT POTS ON AMPS ARE PROPERLY SET. TURN THEM UP UNTIL YOU HEAR A BUZZING, THEN TURN THEM BACK JUST UNTIL THE BUZZING STOPS. 3) FOLLOW TROUBLESHOOTING GUIDE DOWNLOAD HERE




SAW HEAD WILL NOT HOME


1) CHECK IF THE SAW HEAD IS AGAINST THE HARDSTOP IF IT IS, ENSURE IT IS NOT WEDGED AND PHSYICALLY STUCK 2) ENSURE THE CORRESPONDING SERVO AMP IS POWERED ON AND DOES NOT HAVE ANY FAULT LIGHTS. SHOULD ONLY HAVE A RED RESET LIGHT AND A GREEN POWER LIGHT 3) VERIFY THE CABLES AT THE AMP AND MOTOR ARE NOT DAMAGED AND ARE CONNECTED PROPERLY AND TIGHT HAVE ANSWERS FOR THESE BEFORE CALLING: A) DOES THE SAW HEAD JERK WHEN COMMANDED? B) JOG A 2X4 CONTINUOUSLY THROUGH THE SAW. DOES IT STOP AND GO?




SAW HEAD SLAMS (BOTH WEBSAW OR XL-SAW)


AIR PRESSURE SHOULD BE NO MORE THAN 65PSI WEBSAW
1) A CARRIAGE DAMPER ( EG-0001 or MAKE YOUR OWN) MAY BE REQUIRED TO REPLACE FAULTY SHOCK ABSORBER. 2) CUSHION INSIDE 6" CARRIAGE CYLINDER MAY BE DAMAGED.

XL-SAW:
1) CHECK THAT THE FLOW RESTRICTOR ( PB-0006) TO THE CARRIAGE IS PROPERLY ADJUSTED.




MAKES ONE CUT AND STOPS (WEBSAW ONLY)


1) CHECK THAT AFTER THE FIRST CUT IS MADE THAT THE ON SCREEN INDICATOR SAYS "SAW CARRIAGE UP" IF IT DOES NOT SAY UP: A) CHECK THAT THE UPPER PROX SWITCH IS OPERATIONAL B) CHECK THE UPPER CARRIAGE IS MAKING IT UP HIGH ENOUGH FOR THE UPPER PROX SWITCH TO ACTIVATE C) CHECK THAT CARRIAGE DAMPER IS NOT CONTINUOUSLY BLOWING AIR. THIS INDICATES BAD SEALS IN THE CARRIAGE CYLINDER




SAW HEAD WILL NOT DROP (WEBSAW ONLY)


1) CHECK THAT CARRIAGE SAYS "UP" POSITION ON SCREEN. IF SAW HEAD IS UP AND THE SCREEN INDICATES ANYTHING BUT "UP", UPPER PROX OR CABLE IS BAD 2) CHECK THAT INFEED SENSORS ARE SEEING THE BOARD ENTER THE MACHINE. IF THERE IS NO SIGNAL THAT THE SAW SEES THE BOARD IT WILL NOT BEGIN CYCLE. INFEED SENSORS OR CABLES ARE BAD. 3) IF CARRIAGE SAYS UP AND CYCLE BEGINS WHEN THE BOARD ENTERS THE MACHINE, CHECK THE CERAM VALVE THAT CONTROLS THE CARRIAGE CYLINDER (CENTER VALVE IN BACK USUALLY) MECHANICALLY OPERATE THE CYLINDER BY TURNING THE RED SCREW ON THE SOLENOID.
A) IF IT DOESN'T OPERATE, THE CERAM IS BAD OR NEEDS OIL. B) IF IT DOES OPERATE, CHECK THAT IT IS RECEIVING SIGNAL. TURN ON M54 VALUE, CHECK FOR VOLTAGE AT THE SOLENOID PLUG. IF YOU'RE GETTING VOLTAGE AT THE PLUG, THE SOLENOID IS BAD. IF THERE IS NO VOLTAGE AT THE PLUG, CALL FOR FURTHER ASSISTANCE.




SAW HEAD WILL NOT RISE AFTER CUT IS MADE (WEBSAW ONLY)


1) CHECK THAT CARRIAGE DAMPER IS NOT CONTINUOUSLY BLOWING AIR. THIS INDICATES BAD SEALS IN THE CARRIAGE CYLINDER SEALS: ( PC-0001-1) BOTH ARE REQUIRED 2) CHECK LOWER PROX SWITCH ( EG-0004 & EC-0001) IS ACTIVATED AND OPERATIONAL 3) JTHW CABLE FROM 50TB PLUGGED INTO PARALLEL PRINTER PORT ON COMPUTER. SOLUTION: CONNECT JTHW CABLE TO CORRECT PORT ON COMPUTER. DO NOT CONNECT ANYTHING TO PARALLEL PRINTER PORT




SAW PANEL IS OVERHEATING


1) CHECK THAT AIR FILTER IS CLEAN REPLACE FILTER WITH PUROLATOR A40004 OR EQUIVALANT 2) ENSURE FAN IS NEAR THE TOP OF CABINET, AND IS SUCKING AIR "OUT" OF CABINET




NOT CUTTING THROUGH BOARD / OR CUPPING ON TOP


1) INCREASE YOUR DROP TIME. MEASURED IN MILLISECONDS. DO NOT GO OVER 700 2) CHECK FLOW CONTROL ISN'T CLOSED 3) CONFIRM CYLINDER AND RELATED CERAM ARE PROPERLY OILED. 4) CYLINDER AIR SEALS ARE FAILING SEE GUIDE HERE




IRREGULAR LENGTHS +/- (90 DEGREE IS ACCURATE, OVER 90 IS LONG, UNDER 90 IS SHORT)


90 DEGREE IS ACCURATE, OVER 90 IS LONG, UNDER 90 IS SHORT 1) CHECK BLADE CENTER LINE A) ( WEBSAW INSTRUCTIONS) IF CENTERLINE IS OFF, CHECK CARRIAGE BEARINGS B) ( XL-SAW INSTRUCTIONS) IF CENTERLINE IS OFF, REALIGN USING ATTACHED INSTRUCTIONS, CONFIRM BLADE CLEARS IN ALL DIRECTIONS BEFORE RUNNING
