Replace the SRU (SRU-H / SRU-L / SRU-POWER)

Replace the SRU — the slip ring unit's SRU-H, SRU-L, or SRU-POWER assembly — by locking the gantry rotation, unbolting the assembly, carting it out on the SRU replacement jig, and fitting the new unit in reverse.

Applies to
Aquilion 16 (TSX-101A)
Personnel
2 technicians · Intermediate-to-advanced — five gantry covers (Mylar ring, front cover, side covers, front/rear base covers, upper cover) plus the right side projector come off just to reach the unit; the SRU replacement jig (CLX-21620-1) is used to support and cart a heavy rotating assembly out of the gantry; cable connectors and their metal covers are disconnected; and the whole job is bracketed by locking, unlocking, and re-locking the rotation section (steps 7 and 9) around the bolt-removal step — exactly the crush hazard the section's WARNING addresses. No torque value, electrical test, or calibration step is called out in this section. (Skill assessment derived from procedure content — not an OEM-stated skill level.)

Safety

WARNING

Hazard: Removing a heavy component from the gantry rotation section without first engaging the mechanical brake (rotation lock pin)

Consequence: The gantry rotation section may rotate due to the weight imbalance created by the part's removal, possibly resulting in personal injury

Avoidance: Engage the mechanical brake (rotation lock pin) before removing any heavy component from the rotation section
