Alarm — high severityXC (X-ray Controller)

B2630000 — Exposure time exceeded — X-ray timing alarm from the XC

Canon Medical (Toshiba) CT error code, reported by the XC (X-ray Controller).

What B2630000 means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 and Aquilion S16 and Asteion Super4 and Aquilion 16 CT systems, status code B2630000 indicates: Exposure time exceeded — X-ray timing alarm from the XC. The code originates in the XC (X-ray Controller) section of the XC (X-ray Controller). Severity level A1 (Alarm — high severity).

Reported action: Record the protocol, rotation time and scan length that produced the fault, plus whether it happens on long helical acquisitions only. Then have the XC exposure timing and the generator's exposure control checked. Do not keep repeating the acquisition on the patient while this high-severity alarm is active..

Reported on Aquilion 16, Aquilion RX/V4-62R004, Aquilion ONE/V4.2, Aquilion S16, Asteion Super4 and V3.20R003. It comes from the 4:Device XC table, where the OEM text reads "Error in XC ( exposure time exceeded )."
