183319 — HEMRC drive output current exceeds the 55% MAXIMUM tolerance, stops the scan
GE Healthcare CT error code, reported by the GE LightSpeed CT platform.
What 183319 means
On LightSpeed Plus and LightSpeed Ultra and LightSpeed QX/i CT systems, status code 183319 indicates: HEMRC drive output current exceeds the 55% MAXIMUM tolerance, stops the scan. The code originates in the Gantry High Voltage Generator section of the GE LightSpeed CT platform. Severity level error (Error condition).
Reported action: Treat this as the scan-stopping counterpart of the 183318 rotor-current warning — check the X-ray tube stator, HEM-IT and HEMRC power supply per the manual's diagnostic sequence, and confirm tube service life/mAs before replacing parts..
Raised on LSPlus/LSUltra/QXi systems (2.x-3.x hardware) when the HEMRC (gantry high-voltage generator) drive's output current exceeds 55% of its maximum rotor-current tolerance; unlike the related 183318 warning, this condition stops the scan.
