Error Code System Message
ERROR 461 - 60 Hz inverter OK signal low during exposure interlock
Question
What does ERROR 461 mean on a GE AMX-Series mobile X-ray?
Short Answer
ERROR 461: 60 Hz inverter OK signal low during exposure interlock.
Possible Causes
60 Hz inverter OK status was not present.
Troubleshooting Steps
Check inverter OK/status line, CPU input and inverter/relay circuitry.
Parts Areas to Check
Generator control board; CPU board; inverter/rotor/filament/tap/HV subsystem indicated by the fault

462
Question
What should I check for error 462 on the AMX-4 Series?
Short Answer
1) Check wires to Power Module SCR Q3 block on AMX1A4 panel for loose connections. 2) Check mA metering circuit/calibration: AR125 Pin 1 or TP-3 (ref. TP-5) on Filament kVp Board = 4.7 V/100 mA. 3) Batteries may be soft; refer to Error 465; could be one bad cell up to full pack. 4) Check High Voltage Bleeder. 5) Check Battery Charger Board or open fuse F4. 6) Errors 462 and 466 with breaker tripping on exposures above 48 kVp: check/replace HV Transformer Tank. 7) Error 462 on exposures >70 kVp with Error 439 closed-loop resistance: recalibrate unit. 8) Error 462 during calibration with no exposure termination, but normal termination in Check-Sum Bypass mode: spark gap may be shorted. 9) Check Filament kVp Board J3 pins 3 and 4 for high-resistance jumper. 10) Check battery connections.
Possible Causes
1. Check Wires To Power Module SCR Q3 Block On AMX1A4 Panel For Loose Connections 2. Faulty MA Metering Circuit - Or Out Of Calibration– (AR125, Pin 1 Or TP-3 [Ref. TP-5] On Filament kVp Board = 4.7V/100MA) 3. Batteries May Be Soft - Refer To ERROR 465 - could be 1 Bad Cell Up To Full Pack 4. could be Faulty High Voltage Bleeder 5. Battery Charger Board Failure Or Fuse F4 Open 6. Errors 462 And 466 - Tripping Breaker With Exposures Above 48 kVp = Replace HV Transformer Tank 7. Error 462 On Exposures >70 kVp And Error 439 Closed Loop Resistance? = Re-Calibrate Unit 8. ERROR 462 During Calibration With NO Exposure Termination (Counts Actual Time)—In Check-Sum Bypass Mode, The Exposure Terminates Normally (Uses Time Selection only). Solution: SPARK GAP SHORTED. 9. Filament kVp Board J3 Pins 3 And 4 (Jumper Has High Resistance) 10. Check for loose battery connections.
