Siemens Multix Swing
Siemens Healthineers · Model Multix Swing
Ideally suited for the complete range of routine examinations. MULTIX Swing Fit for purpose. Easy to use. MULTIX Swing is a compact, cost-efficient radiography workplace based on a cassette catapult bucky. As a reliable, easy-to-use solution, MULTIX Swing is especially suited for all acquisitions of skeletal radiography of the recumbent and seated patient.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
No or inconsistent exposure / generator error
HighSymptoms: Exposure inhibited, generator error / fault code, images consistently under- or over-exposed.
Root cause: HV generator / inverter fault, an exposure-switch / contactor fault, an HT-cable fault, or a tube-load / thermal interlock.
kV / mA / mAs inaccuracy
HighSymptoms: Output does not match the console, techniques drift, generator calibration fails.
Root cause: Inverter / HV-tank fault, a filament-supply fault, or a calibration issue.
AEC (phototimer) fault
MediumSymptoms: Auto-exposure images consistently over- or under-exposed, chambers not tracking.
Root cause: AEC ion chamber(s) or the AEC calibration.
Tube-stand / table / bucky / collimator fault
MediumSymptoms: Column, wall stand, table or bucky will not track / detent; collimator light out; grid errors.
Root cause: Drive / brake / detent hardware, the collimator lamp / drive, or a bucky-motor fault.
Tube overload / cooling lockout
LowSymptoms: Exposures inhibited after a series, tube-heat alarm.
Root cause: Tube housing heat limit reached or a cooling-fan fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No exposure or kV / mA error
- Note the exact generator error code.
- Confirm the mains supply is within the generator's spec (line-voltage compensation).
- Check the HT cables and the exposure contactor.
- Confirm the tube is not in a thermal lockout.
- Escalate a confirmed inverter / HV-tank / filament fault; verify output with an X-ray analyser after repair.
Symptom: AEC images over/under-exposed
- Verify the AEC response with a phantom at two thicknesses.
- Check the AEC chamber connections and the selected chambers / density.
- Recalibrate the AEC per the service procedure.
- Compare to a manual technique.
- Replace the AEC chamber if it will not calibrate.
