Data acquisition system checks: temperature, connectors, line-voltage pins, fuses, fan, window — 4.1-4.6
Run the Aquilion 16's six periodic checks on the data acquisition system — main-detector temperature, detector/DAS cable-connector security, DAS line voltage at four connectors, DAS fuses, DAS cooling fans, and the main detector's X-ray window — and use the DAS power supply's adjustment VR to bring an out-of-range voltage back into tolerance.
Applies to
Aquilion 16 (TSX-101A) — periodic inspection items 4.1 through 4.6, "4. Data Acquisition System" (source subsection 5.4) of the periodic-inspection table, source volume 2Y201-061 (Check and Maintenance Procedures). These six items are the whole DAS entry in the master schedule (see Related) and sit between the X-ray/HV item block (3.1-3.19) and the Data Transfer Unit block (5.1-5.2). The table's own column headers show four checking-period buckets, 3M / 6M / 1Y / 2Y, but the specific interval mark for each of 4.1-4.6 was not preserved by the text extraction of the table (the same limitation already noted on several neighboring items in this corpus) — confirm the checked period against the printed table in source 2Y201-061E*E p.116-118 before scheduling.
Personnel
1 technician · Basic — reading a temperature-controller display, visually confirming four named cables are seated, measuring six DC voltage pin-pairs against printed tolerances (adjusting an onboard VR if a reading is out of range), visually confirming eight fuses are not blown, confirming two fans rotate, and wiping a window with an alcohol-moistened cloth. No board-level rework or calibration beyond the single VR adjustment is called out in source. (Skill assessment derived from procedure content — not an OEM-stated skill level.)
