ProcedureDetector/DASReplace
Replace the REF detector
Replace the REF detector by unplugging its connector, removing the wedge/slit section with the tube parked at 180°, and unbolting the detector from the collimator — then remount it clean and fully insulated from the gantry, and confirm the REF channel's output before closing the job out.
Applies to
Aquilion 16 (TSX-101A) — data acquisition section volume 2D201-065, subsection 6.2.4 "Replacement of the REF detector." Printed directly after the calibration data acquisition subsection (6.2.3, p.96) and the main detector replacement subsection (6.2.2, p.89-95) inside the Repair chapter's "Before Repair" section (6.2), which states that the DAS PWB, main detector array, and REF detector are the three replacement jobs it covers.
Personnel
Intermediate — source itself flags the REF detector as "a high-precision part" to "handle... with care." The job unplugs the REF connector and its cable, removes the wedge/slit section (with the tube parked at the 180° position to ease access), and unbolts the detector's M4 screw and insulating washer from the collimator; remounting requires cleaning the inspection window and confirming the whole detector body is fully insulated from the gantry before the DCA/NRA checks are trusted. No torque value or multi-person lift is stated for this item (skill assessment derived from procedure content — not an OEM-stated skill level).
