It offers a choice of worktable capacities, each with buildingblock modularity that brings convenient scalability, proven liquid handling, easy-to-use robotics and advanced process control within reach of every laboratory scientist.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Sample-transport / track fault
HighSymptoms: Carriers / pucks jam, stall, or mis-route; track-error message; throughput drops.
Root cause: Worn track belts / drive, a diverter / gate fault, or a carrier-sensor fault.
Robotic gripper / pick-place fault
MediumSymptoms: Tubes dropped or mis-placed, gripper-position error, aliquotting mis-aligned.
Root cause: Worn gripper / robot drive or an encoder / home-sensor fault.
Centrifuge module fault
MediumSymptoms: Inline centrifuge imbalance, lid-lock error, will not spin.
Root cause: Drive / bearing wear, a lid-lock fault, or an imbalance-sensor fault.
Decapper / recapper / aliquotter fault
MediumSymptoms: Caps not removed / applied, aliquot volumes off, station jams.
Root cause: Worn decapper jaws, aliquot-probe / syringe wear, or a station-drive fault.
Middleware / connectivity fault
HighSymptoms: Analysers or the LIS drop off the line, rules not applying, samples stuck in a queue.
Root cause: The automation middleware / server or a network link.

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 controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing 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: QC / calibration failure across a channel or the whole system
- Run fresh controls at all levels and note which analytes fail.
- Confirm reagents are in date, correctly loaded, mixed and not bubbled.
- Run the photometer / lamp-energy check and replace the lamp if energy is low.
- Clean the sample and reagent probes, the mixers and the wash / cuvette-wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Sample or reagent probe clog / crash / short aspiration
- Inspect the probe for a bend or blockage and clear it (wire / sonicate per the manual).
- Run the fluidics prime and the probe-wash cycle.
- Check for a clot or fibrin in the sample and the liquid-level sensing.
- Verify probe positioning / alignment.
- Replace the probe if aspiration is still short.
Symptom: ISE electrolyte results biased or noisy / ISE calibration fails
- Run the ISE calibration and check the slope / drift against spec.
- Replace an ISE electrode or the reference that is at end of life.
- Check the ISE pinch valves and tubing for wear or air.
- Confirm the ISE standard packs are in date.
- Re-run ISE QC before releasing electrolyte results.
Symptom: High cuvette blanks / position-dependent results
- Run the cuvette blank / photometric check.
- Clean or replace worn / scratched cuvettes or the reaction segment.
- Check the cuvette-wash station nozzles and drying.
- Confirm the water / DI supply quality.
- Recalibrate and re-run QC.

There is a software issue that can potentially impact sample identification and traceability under specific conditions when using EVOware Add On Software: Sample Tracking -Multi Instrument V1.0 or higher, Part Number 30019971.
- RECALL
Distortion (noise interference) of the liquid level capacitance can result in air aspiration instead of liquid aspiration. This might cause a false signal (air detection) with possible dispense errors resulting in erroneous results.

WIth TouchTools 3.0 after the execution of a Rich User Prompt in Display and Wait mode, door lock errors are ignored. If an operator presses "Continue" following a Rich User Prompt and the door has been left open, the script will progress (continue without warning). This could lead to the instrument moving unexpectedly and potentially cause an injury to the operator if they are physically inside t
