XC Maintenance Program: block test, exposure/running test, debug monitor and screens

Run the XC maintenance program's own block test, exposure test, running test, and cyclic debug-monitor read-out — the four built-in functional checks that confirm the SRU inverters, X-ray exposure path, and XC status reporting are all working, once the maintenance program is already connected and its test switch is set active.

Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume 2D201-064, section 8.4 "XC Maintenance Program," subsections 8.4.8 Block test, 8.4.9 Exposure test/running test, and 8.4.10 Debug monitor (source, p.103-104), plus the maintenance-program screen figures 8.4-1 through 8.4-9 printed immediately after (source, p.105-109). Assumes the PC-terminal connection, communication program, and test-SW Setting from subsections 8.4.1-8.4.3 are already in place — see [XC Maintenance Program: outline, connection and menu](toshiba-ct-aquilion16-xray-maint-program-setup.md) (Related).
Personnel
Intermediate — operate the maintenance program's Setting / Block test / Automatic test screens, iteratively trim the KL setting value while respecting the KL>=200 floor, set exposure conditions and rotor ON in the condition setting screen for the exposure/running tests, and hand-decode a captured cyclic debug-monitor status line (converting individual ASCII characters into an 8-bit binary code and reading the resulting 37-character string across its 10 named fields). (Skill assessment derived from procedure content — not an OEM-stated skill level.)

Safety

NOTICE

Hazard: Reducing the KL (inverter drive) setting value below 200 while running the block test, in an attempt to raise a 0 kV or out-of-range reading

Consequence: The SRU inverter rating may be exceeded and the inverter may be damaged (equipment damage only — source labels this callout "CAUTION"; reclassified here as NOTICE per FSELIB convention because the stated consequence is equipment damage, not personal injury)

Avoidance: Do not reduce the KL setting value below 200 during the block test. If the output is still out of range at KL 200, do not keep lowering it — check the main inverter clock signal on the SRU filter board instead (see XC PWB reference, Related, which documents the identical KL>=200 floor from the PWB side).
