Troubleshoot kV/mA output faults (Over mA, Under mA, HV overcurrent, Under kV)
Work the Aquilion 16's four X-ray generator output-fault decision trees — **Over mA**, **Under mA**, **HV overcurrent**, and **Under kV** — using the OEM's own flowcharts for the SRU generator's kV/mA output path (source §8.2.1-8.2.4, p.77-80).
Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume, source 2D201-064, sections 8.2.1-8.2.4 (Over mA / Under mA / HV overcurrent / Under kV output faults), p.77-80.
Personnel
1 technician · Intermediate — electrical fault isolation on the SRU generator's kV/mA output path: reading the XC error log for FOC/FO4 codes, checking the If adjustment waveform and readjusting the If value, running a heat test and measuring X-ray tube return-cable/filament resistance, checking the mA and HV waveform (Signal Show) and the kV detection cable, and performing a block test with Nos. 11 to 19 set to ON — escalating to replacing the XC, the XC PWB, the SRU-H, the SRU-L, or the X-ray tube (skill assessment derived from procedure content — not an OEM-stated skill level).
