Most DRGEM service manuals are organized into the following core chapters:
| Error Code | Description | Likely Root Cause | Service Action (per manual) | | :--- | :--- | :--- | :--- | | | Filament Preheating Fail | Broken filament or filament driver fault | Measure tube filament resistance. Check driver board F1 fuse. | | E-204 | Rotor Stalling | Damaged stator windings or bearing seizure | Run rotor test mode. Check stator continuity (approx 20-40 ohms). | | E-307 | AEC Ion Chamber Timeout | Defective chamber or exposure termination logic | Test with non-AEC technique. If resolved, replace AEC board. | | E-415 | Detector Communication Lost | WiFi interference or Ethernet cable failure | Ping detector IP (default 192.168.10.50). Re-pair wireless. | | W-501 | Tube Overload (Thermal) | Excessive heat unit accumulation | Allow cooling. Check anode thermal sensor calibration. | drgem x ray service manual
| Error Code | Description | Troubleshooting Steps (from manual) | |------------|-------------|---------------------------------------| | | Communication timeout between console and generator | Check RS-232 or Ethernet cable. Verify baud rate settings. Reboot both units. | | E-045 | Rotor not reaching target speed | Measure rotor drive voltage (80–110 VAC). Check stator winding resistance (~10–15 ohms). Replace tube if shorted. | | E-102 | Detector panel not detected | Re-seat detector cable. Verify USB or GigE connection. Reinstall detector driver via service utility. | | E-208 | Collimator leaf position error | Perform collimator homing routine. Clean optical encoder strip. Replace leaf motor if seized. | | E-317 | AEC chamber saturation | Reduce mAs or switch to manual mode. Test chamber ionization current with picoammeter. Replace chamber if leakage >1 nA. | Introduction Most DRGEM service manuals are organized into
