183318 — HEMRC drive output current exceeds the 45% WARNING rotor-current tolerance
GE Healthcare CT error code, reported by the GE LightSpeed CT platform.
What 183318 means
On LightSpeed Plus and LightSpeed Ultra and LightSpeed QX/i CT systems, status code 183318 indicates: HEMRC drive output current exceeds the 45% WARNING rotor-current tolerance. The code originates in the Gantry High Voltage Generator section of the GE LightSpeed CT platform. Severity level warning (Warning condition).
Reported action: Correlate this warning with the X-ray tube's accumulated mAs/service life and any use of 0.5-second scan protocols before condemning the HEMRC — the manual walks through the log-grep procedure and the tube-related root causes engineering identified for this error..
Raised on LSPlus/LSUltra/QXi systems (2.x-3.x hardware) when the HEMRC (gantry high-voltage generator) drive's output current exceeds 45% of its warning rotor-current tolerance — a condition that does not by itself stop scanning.
