Identify the defective inverter before replacement
Before swapping any inverter in the Aquilion 16's SRU generator, use the Maintenance Tool's Status 2 and Status 1 codes (source §8.5.1, p.113-114) to pin the fault to one specific inverter position and tell a blown fuse from an overheat/regenerative-signal condition — so the replacement (and any required XC adjustment) lands on the right board the first time.
Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume, source 2D201-064, section 8.5 / 8.5.1 ("Inverter Replacement" / "Checking whether the inverter in the SRU generator should be replaced or not", p.113-114).
Personnel
1 technician · Intermediate — using the Maintenance Tool to read the Status 2 code and group it into 4-bit blocks against the inverter-number key to find the defective inverter, then reading the same inverter's Status 1 bit to tell a blown fuse from an overheat/regenerative-signal condition, and following the OLP%-based branch (fan check vs. slight degradation/ventilation vs. cooled-and-persists) to the right corrective action (skill assessment derived from procedure content — not an OEM-stated skill level).
