M13 — Rotor Control Board ARM processor warning
Philips CT error code, reported by the Rotor Control Board.
What M13 means
On Access Series CT (6/16/Dual) CT systems, status code M13 indicates: Rotor Control Board ARM processor warning. The code originates in the Rotor Control Board section of the Rotor Control Board. Severity level warning (Warning — recoverable condition).
Reported action: Check the Rotor Control Board ARM/Spartan communication LEDs (Table 1-1) for an intermittent condition; monitor for recurrence and replace the Rotor Control Board if the warning becomes persistent..
Listed in Table 1-3 'Stator Control Board Error Code vs System Error Code' of the Philips Access CT Service Trouble Shooting Guide (459800863401 Rev. C), between codes n12 and n14 in the 'nxx' warning range. The source text prints this code as 'm13' (likely a print/OCR artifact for 'n13'); reproduced verbatim as it appears in the document.
