185553 — HEMRC drive detected a Line Loss (input power below 85% of bus voltage)
GE Healthcare CT error code, reported by the GE LightSpeed CT platform.
What 185553 means
On LightSpeed Plus and LightSpeed Ultra and LightSpeed QX/i CT systems, status code 185553 indicates: HEMRC drive detected a Line Loss (input power below 85% of bus voltage). The code originates in the Gantry High Voltage Generator section of the GE LightSpeed CT platform. Severity level error (Error condition).
Reported action: Correlate this with any accompanying 183318/183319 rotor-current warnings before condemning the HEMRC power supply — the manual details the log-grep procedure and the tube-service-life thresholds used to isolate stator, HEM-IT or power-supply causes..
Raised on LSPlus/LSUltra/QXi systems (2.x-3.x hardware) when the HEMRC (gantry high-voltage generator) drive detects a Line Loss — input power to the drive has fallen below 85% of the nominal bus voltage, often tied to the X-ray tube rotor drawing excess current.
