Troubleshoot X-ray tube flow and thermal faults
Work the Aquilion 16's two X-ray tube cooling-interlock faults — **X-ray tube flow fault** and **X-ray tube thermal fault** — using the OEM's own two decision-tree flowcharts (source §8.2.6-8.2.7, p.83-84).
Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume, source 2D201-064, sections 8.2.6-8.2.7 (X-ray tube flow fault / X-ray tube thermal fault)
Personnel
1 technician · Intermediate — electrical fault isolation on the tube-cooling interlock loop: monitoring the 200 VAC input, continuity/voltage checks at terminal board TB5, fuse checks (F4/F5) on the power supply unit, and jumpering TB5 pins as a bypass test — escalating to replacing the oil cooler, the X-ray tube, or the XC PWB when a check does not clear the fault (skill assessment derived from procedure content — not an OEM-stated skill level)
