X-ray tube malfunctions troubleshooting and malfunction-code reference
Work through five X-ray-tube-specific fault families — discharge during exposure, oil leakage, tube interlock trips, abnormal noise, and no tube current — using the OEM's own symptom-to-cause guidance, then classify or log any tube malfunction with the source's three-axis malfunction/error-code scheme.
Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume, source 2D201-064 §8.3 ("Troubleshooting for X-ray Tube"), p.94-96. Sits between the generator troubleshooting table (§8.2/Table 8.2-1, p.91-92) and the XC Maintenance Program setup section (§8.4, p.97). Covers symptom-to-cause guidance for the X-ray tube itself — discharge during exposure, oil leakage, tube interlock (flow/thermal), abnormal noise, and no tube current — plus a [REFERENCE] malfunction/error-code table (p.96) that closes the chapter.
Personnel
1 technician · Intermediate — matching an observed tube symptom (discharge, oil leak, an interlock trip, abnormal noise, or no tube current) to this section's probable-cause guidance, then judging whether to inspect/adjust (fit and clean a bushing, age a new tube with frequent operation) or escalate to replacing a suspected part (the X-ray tube, the high-voltage cable, the high-voltage transformer, the cable bushing, the oil pump/hose, the cooler/fan, or the XC PWB via the stator/rotor path). Also covers reading the source's own three-axis malfunction/error-code scheme (symptom letter A-H, a source-of-failure sub-code, and a frequency code) used to classify and log X-ray tube malfunctions.
