Applies to
Aquilion 16 (TSX-101A)
Personnel
1 technician · Intermediate — mechanical removal/replacement of the rotation-direction photo sensor behind the MUDAT external cover (cover access, 2 mounting screws for the cover, 2 for the sensor, plus a spacer and a shim that must be handled carefully and reused), followed by a rotation-speed check — and, if that check fails, the cross-referenced fine-adjustment or MR-sensor-adjustment procedure — to confirm the replacement didn't disturb rotation timing (skill assessment derived from procedure content — not an OEM-stated skill level).
