Question
What should I check for error 45C on the AMX-4 Series?
Short Answer
1. Check for 80 VAC At CR4 Black Leads On AMX1A4 Panel With PREP Pressed 2. Check for About 75 VDC Across AMX1A4 C2/C12 With PREP Pressed 3. Check for Correct Polarity Of CR1 & CR2 (CR7/CR13) On AMX1A4 Panel 4. Bad 1 kHz inverter Driver Board 5. Are The Tap Relays Energizing? 6. Is “Stop Cap” At J4-11 (1 kHz Inverter Driver Board) Approximately 80 VDC?

ERROR 45C - 1 kHz inverter ready missing after 60 Hz inverter start
Question
What does ERROR 45C mean on a GE AMX-Series mobile X-ray?
Short Answer
ERROR 45C: 1 kHz inverter ready missing after 60 Hz inverter start.
Possible Causes
The 1 kHz inverter-ready signal did not assert.
Troubleshooting Steps
Check inverter-ready signal, inverter control and CPU critical-status input.
Parts Areas to Check
Generator control board; CPU board; inverter/rotor/filament/tap/HV subsystem indicated by the fault

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.
