NOTES : 
PROBLEMS GETTING THE TOP DRY SERIES 2000 AUTOFLOW SYSTEM TO FUNCTION PROPERLY.  THE PROBLEMS ARE AS 
FOLLOWS, THE SYSTEM 
WILL FONCTION PROPERLY ON OCCASION, AFTER APPROXIMATELY AN HOUR OF FUNCTIONING THE INFORMATION ON THE 
LCD SCREEN WILL FREEZE AND NO 
LONGER CHANGE ITS VALUES, THE FAN AND BURNER OF THE MASTER WILL HAVE STOPPED FUNCTIONING AND THE SLAVE 
UNIT WILL BE ON FULL HEAT 
ON HIGH FIRE.  ONCE THE SYSTEM IS SHUT DOWN AND POWER CYCLED BACK ON, ALL THE TEMPERATURE VALUES ARE 
INDICATED AS HIGH GRAIN 
HI-LIMIT, PLENUM HI-LIMIT.  THE SERIES 2000 BOARD ON THE MASTER WILL ALSO BURN OUT PERMANENTLY ON 
OCCASION AND NEED TO BE 
REPLACED.  

AFTER A FEW EXCHANGES WITH OUR SALES REP AND BRIAN BROWN/GSI, IT WAS RECCOMENDED TO REPLACE ALL THE 
COMM WIRE FOR THE SYSTEM.  
WE PASSED A TEMPORARY WIRE FOR THE COMM AS WELL AS THE 120V FOR THE ENTIRE RUN BETWEEN THE AUTOFLOW 
PANNEL THE MASTER AND 
THE SLAVE AFTER EXTENSIVE TESTING THE ISSUE WAS STILL NOT RESOLVED, THE SYSTEM WOULD FREEZE AS WELL AS 
DESTROY SERIES 2000 
BOARDS.

WE THEN VERIFIED EXTENSIVELY THE WIREING ON THE AUTOFLOW PANNEL, THE MASTER AND THE SLAVE UNIT.  WE 
DISCOVERED AN IMPROPER 
JUMPER INSTALLED ON THE SLAVE UNIT ON TERMINAL 32 (J6-01) GOING TO THE TERMINAL 5 (COMM1-2) WHICH WAS 
CREATING A SHORT AND 
BURNING OUT OCCASIONALLY THE SERIES 2000 BOARD ON THE MASTER BURNER UNIT BY SENDING 120V DIRECTLY 
THROUGH THE 
COMMUNICATIONS LINE SHORTING OUT ONLY THAT BOARD.  THIS CORRECTED THAT ISSUE BUT DID NOT RESOLVE THE 
OCCASIONAL FREEZING OF THE 
SYSTEM.

AFTER MORE EXTENSIVE VERIFICATION.  IT WAS DETERMINED THAT THE SYSTEM WOULD FREEZE UPON IGNITION OF THE 
MASTER BURNER, IT WOULD 
\'\'FREEGAME\'\' STOP RESTART AND SOMETIMES IGNITE BUT ESSENTIALLY IT SEEMED AS IF THE BOARD WOULD HAVE 
SHORTED OUT, CAUSED SOME SORT 
OF ERROR BUT STAYED IN AN \'\'OK\'\' STATUS ALLOWED THE SLAVE UNIT TO FUNCTION NON-STOP AT FULL HEAT HI-FIRE, 
THE MAIN I/O AND DISPLAY 
ARE FUNCTIONING BUT NOTHING IS UPDATING ON THE SCREEN.

WE THEN DISCONNECTED THE IGNITION WIRES TO THE BURNER,  THE SYSTEM WOULD TRY TO FIRE BUT INSTEAD OF 
CAUSING THE SERIES 2000 BOARD 
TO \'\'FREE GAME\'\' IT WOULD SIMPLY LOCK OUT WITH LOSS FLAME ERROR CODE.  WE THEN CONNECTED THE B.GND 
TERMINAL ON THE FENWAL TO 
THE BURNER GROUND (***SEE EXPLAINATION BELOW)  WHICH WHEN RETESTED THE BURNER STILL WOULD NOT IGNITE 
BUT WOULD NOT CAUSE ISSUES 
WITH THE SERIES 2000 BOARD EITHER.  WE THEN VERIFIED THE IGNITION PROBES AND DETERMINED THAT THE PROBES 
MIGHT BE INSTALLED TOO 
CLOSE TO THE BRACKET THAT SUPPORTS THEM, AFTER AJUSTMENT THE SYSTEM WAS RESTESTED AND ALL THE ISSUES 
SEEMED TO BE RESOLVED.

***FENWAL RECCOMENDS TO NOT INSTALL THE B.GND TERMINAL TO THE BURNER GROUND AS THIS WILL PREVENT 
DAMAGE TO THE IGNITON BOARD AS 
WELL AS MAKE THEM \'\'LAST\'\' LONGER.  THE ISSUE WITH THIS IS IF THE IGNITION PROBE DOES SHORT TO THE BURNER 
GROUND AND B.GND IS NOT 
WIRED TO THE BURNER GROUND, THERE WILL BE 6000V FLOWING INTO THE CONTROL PORTION OF THE CIRCUIT 
CAUSING ALL SORTS OF ISSUES ON THE 
CONTROL CIRCUITRY (IN OUR EXAMPLE THE SERIES 2000 BOARD WOULD FREEZE UP AND FREEGAME, LEFT UNATTENDED 
THE SLAVE UNIT WILL HAVE 
CONTINUED TO RUN AND COULD HAVE BURNED DOWN THE ENTIRE DRYER).  BY INSTALLING THE B.GND TO THE BURNER 
GROUND THIS DOES TWO 
THINGS, THE IGNITION PROBES WILL FUNCTION IN THE SAME INTENDED WAY, HOWEVER IN THE EVENT OF A SHORT, THE 
REST OF THE SYSTEM IS 
PROTECTED, THE SECOND ADVANTAGE IS FOR THE FLAME DETECTION, AS THE FLAME SIGNAL HAS TO PASS THROUGH 
THE FLAME SENSOR IT CAN NOW 
RETURN ANWHERE THROUGH THE PATH OF THE BURNER GROUND.  (THIS SHOULD BE THE DEFAULT INSTALLATION 
METHOD)
