Troubleshooting AMX
Error Number
Error 45E
Error Code / System Message
45E
Error Question
What should I check for error 45E on the AMX-4 Series?
Short Answer
1) Check for 2 kHz Phase 1 & 2 signals at J2-17 & 19 of Filament kVp Board. 2) Check continuity between J5 plug on Filament kVp Board and filament terminals on HV Transformer Tank. 3) Check for open or shorted X-Ray Tube small filament; is the small spot lit during PREP? A 6 V battery can be applied directly to the filament to see if it will light even though a continuity check may indicate it is OK. 4) Check for defective HV cathode cable (internal short). 5) Replace/check Filament kVp Board and check +24 V to J1-2. 6) If X-Ray Tube is from another vendor, verify it has the required internal resistor in series with filament. 7) Check High Voltage Divider (High Voltage Bleeder). 8) Check FIL SHORTED at J2-25 on Filament kVp Board.
Possible Causes
1. Check for 2 kHz Phase 1 & 2 Signals At J2-17 & 19 Of Filament kVp Board 2. Check for Continuity Between J5 Plug On Filament kVp Board And Filament Terminals On HV Tank Transformer 3. Check for Open Or Shorted X-Ray Tube Small Filament – Is The Small Spot Lit During Prep? A 6V Battery Voltage Can Be Applied Directly To The Filament To See If It Will Lite — Even Though A Continuity Check Of The Filament Might Indicate its Ok 4. Check for Defective HV Cathode Cable (Internal Short) 5. Replace Filament kVp Board - Check the +24 Volts To J1-2 Of Filament kVp Board 6. Is The XRT From Another Vendor? (Must Have Internal Resistor In Series With Filament) 7. Bad High Voltage Divider (High Voltage Bleeder) 8. FIL SHORTED (Check J2-25 On Filament kVp Board)
