What B7220004 means

On Aquilion RX / V4-62R004 and Aquilion ONE / V4.2 CT systems, status code B7220004 indicates: Data transfer system (3) abnormality (MUDAT). The code originates in the MUDAT (gantry-to-console data transfer) section of the MUDAT (Data Transfer). Severity level A1 (Alarm — high severity).

Reported action: Turn the gantry off for a few seconds and retry. If data transfer system (3) keeps faulting, check that transfer system's boards and connectors on both the rotation and stationary sides, note whether systems (1) and (2) are also reporting errors (a common fault upstream points at the shared link rather than one channel), and work through the MUDAT troubleshooting flow in the service manual..
