B7100008 — Error in OPCONT2 (DAS CLOCK count) — DAS data-set count wrong, often a stopped DAS fan

What B7100008 means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B7100008 indicates: Error in OPCONT2 (DAS CLOCK count) — DAS data-set count wrong, often a stopped DAS fan. The code originates in the MUDAT (data transfer system) section of the MUDAT (Multi-Data Transmitting System) — optical data-transfer link. Severity level A1 (Alarm — high severity).

Reported action: Confirm first whether the DAS fan has stopped, which is what the manual instructs for this message. Check LED5 on the Control-16 PWB — it indicates a DAS fan malfunction — and check the Control-16 interface cabling at connector CNN4 and the cable to the DAS power supply at CNN5. Expect the message "Error in offset data Acquisition. Retry Acquisition." alongside it in the same fan-stop scenario. Restore fan operation and DAS power before retrying acquisition; a DAS clock error is latched at the GCIFA only until the next acquisition and also clears using the GCIFA SW4..

Toshiba / Canon Medical CT systems whose DAS feeds the MUDAT link through the Control-16 PWB and the OPCONTA (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). A DAS clock error means the number of data sets transferred from the DAS to the OPCONTA is incorrect. The service manual names this exact console message as one of the two messages produced when the DAS fan stops: the Control-16 PWB monitors fan rotation, and on a stopped fan it shuts down the DAS power-supply output and reports the error to the system.
