43B
Question
What should I check for error 43b on the AMX-4 Series?
Short Answer
1) Check CPU Board. 2) Check cables from CPU Board to 1 kHz Inverter Driver Board and CPU Board to Filament kVp Board. 3) Check HV cable(s). 4) Check HV Transformer Tank; a bad tank may also trip the breaker. 5) Check for bad or old-style 1 kHz Inverter Driver Board; replace with newer style orderable part #46-288764G1 or later, which has more noise immunity. 6) Replace/check Filament kVp Board. 7) Check tap relay contact(s). 8) Check X-Ray Control Module Assembly.
Possible Causes
1) Defective CPU Board 2) Bad cables from CPU Board to 1 KHz Inverter Board and CPU Board to Filament kVp Board 3) HV Cable(s) bad 4) HV Transformer Tank bad (Also breaker trips) 5) Bad or Old Style 1 KHz Inverter Board - replace with newer style orderable part # 46-288764G1 Board or later (has more noise immunity) 6) Replace Filament kVp Board 7) Check tap relay(s)’s contacts, clean with 90% alcohol fast evaporating solvent if there is oxidation 8) X-Ray Control Module Assembly is bad
