BPL Medical Technologies DYNATRAC Ultra
Stress Test Automated Blood Pressure Monitoring: Sun Tech’s TANGO acquisition unit – leading edge technology in accurate motion tolerant BP monitoring for STS HES® HANNOVER ECG system for analysis and interpretation. Advanced Windows-based stress test software enables accurate recording and motion artefacts reduction in stress ECG. Bluetooth enabled wireless ECG transmitter device that provides for the added advantage of portability and reduces motion artefacts. Flexible treadmill protocols.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
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.
Belt slips, drifts or runs rough
HighSymptoms: Walking belt slips under load, tracks off-centre, jerky or noisy.
Root cause: Worn or stretched belt, a worn deck, loss of drive-belt tension, or worn rollers.
Will not start / no speed or incline response
HighSymptoms: Console dead, belt will not move, incline will not change, error code.
Root cause: Breaker / power, a drive-motor or controller fault, a lift-motor fault, or a console-cable fault.
Speed or incline inaccuracy
MediumSymptoms: Actual speed / grade does not match the display or protocol.
Root cause: Speed-sensor or incline-potentiometer / limit-switch fault - needs calibration.
Drive-motor / controller fault
MediumSymptoms: Motor cuts out under load, burning smell, controller error.
Root cause: Worn motor brushes / bearings or a drive-controller fault.
Emergency-stop / safety-key fault
HighSymptoms: E-stop or safety key does not stop the belt, or stops it unexpectedly.
Root cause: Failed e-stop switch / magnet or its wiring - a safety function.

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.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
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: Belt slips or tracks off
- Check and set the walking-belt tension and tracking per the manual.
- Inspect the deck and belt for wear (a worn deck kills belts).
- Check the drive-belt tension.
- Lubricate the deck if the design requires it.
- Replace the belt / deck as a set when worn.
Symptom: Will not start or speed/incline wrong
- Confirm mains, the breaker and the safety key.
- Read any console error code.
- Check the console cable and the drive / lift-motor connections.
- Verify belt speed with a tachometer and calibrate speed / incline.
- Replace the drive controller, motor or incline potentiometer as isolated; confirm the e-stop stops the belt.
