ERROR 443 - X-RAY ON did not become inactive when commanded off
Question
What does ERROR 443 mean on a GE AMX-Series mobile X-ray?
Short Answer
ERROR 443: X-RAY ON did not become inactive when commanded off.
Possible Causes
X-RAY ON remained active when exposure stop was commanded.
Troubleshooting Steps
Check X-RAY ON critical-status input and generator shutdown/control path.
Parts Areas to Check

Question
What should I check for error 443 on the AMX-4 Series?
Short Answer
1. If Power Module SCR Q3 block was replaced in the field, black/white leads to Q3 block on AMX1 A4 panel are reversed between G1/K1 and G2/K2 2. Check for miswired plug at J4 on 1 KHz Inverter Board 3. Check EXP STOP CMND circuit on 1 KHz Inverter Board. EXP STOP CMND and SCR Hi/Lo are single pulses 4. Defective 1 KHz Inverter Board 5. Defective Power Module SCR Q3 block on AMX1 A4 panel
