E0621 — Beam0 X signal path error
Philips CT error code, reported by the Ultrasound.
What E0621 means
On M2424A CT systems, status code E0621 indicates: Beam0 X signal path error. The code originates in the Scanner — Beam circuits (Beam0-Beam3) section of the Ultrasound. Severity level alarm (Alarm — scanner error code).
Reported action: The service note lists this code with data value 1000 as "[Beam0] X signal path error" and names no additional circuit to check, so troubleshooting starts on the Beam0 X signal path itself. Compare the log against the neighbouring beam codes (Beam0-Beam3, X and Y paths, codes E061A-E0628) to see whether a single beam circuit is failing or the whole group, then work through Section 5, Scanner Codes, of service manual M2424-90100-02..
Scanner error codes for the HP/Philips ultrasound system listed as "Model: M2424A" in the Hewlett-Packard Medical Products Group MPG Service Note M2424A-029 (Rev. C, 18 June 1999).
