S-Align - provides precise alignment for superior imaging SID (Source to Image Distance) Guide - supports multiple SSID settings to aid precise device positioning Multi-touch - allows users to control and adjust images easily and intuitively with fingers only Detector charging and storage - radiographers can charge detector and detector battery while traveling and Detector locking function secures detectors to prevent loss.

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 X-ray exposure
High
Symptoms: No exposure on the exposure switch, error / alarm message, exposure inhibited, images under- or over-exposed.
Root cause: HV generator fault, an exposure-switch / hand-switch fault, an HT-cable fault, or a system-battery fault.
Powered-drive / battery fault
High
Symptoms: Motorised drive weak or dead, few exposures per charge, low-battery / drive alarm.
Root cause: Aged battery pack or a drive-motor / charger fault.
Wireless DR detector / image fault
Medium
Symptoms: Detector not connecting, dropped images, poor image quality, calibration overdue.
Root cause: Detector battery / Wi-Fi link, detector damage, or a gain / offset calibration issue.
Column / arm / collimator fault
Medium
Symptoms: The arm drifts or will not hold position, the collimator light is out, tube-angle readout wrong.
Root cause: Worn arm counterbalance / brake, loose fasteners, or a collimator lamp / potentiometer fault.
Console / membrane-switch or cable damage
Low
Symptoms: Unresponsive console keys, intermittent operation.
Root cause: Damaged membrane switch assembly or the console-to-generator cable.

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

Error Codes

Extracted directly from this unit's own service manual.

8001Confirm system is stopped immediately after bumper sensor is activated and THU display error message

Refer to "Chapter 13.18 Bumper Sensor Replacement" in the Parts Replacement manual.

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

Confirm a charged system battery and the mains / charge connection.
Examine the exterior of the control console and the membrane switch assembly, and the console-to-generator cable, for visible damage.
Check the hand switch and its cables, and the HT cables, for damage.
Note the exact error message and look it up in the maintenance guide.
Escalate a confirmed generator / tube fault to Samsung; discharge capacitors before service.

Symptom: Detector / image fault

Confirm the detector battery and Wi-Fi link.
Run the detector calibration (gain / offset).
Inspect the detector for drop damage.
Compare against a phantom exposure.
Replace or refer the detector if calibration will not hold.
