DNA sample prep capability with up to 24 microplates with the AllSpin JS-5.3 Rotor. 3 liter and 4 liter swinging-bucket rotors Fast and Efficient. Fastest accel and decel times with exclusive SR Drive technology. Low heat output and low energy consumption.
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.
Will not start / error at start
HighSymptoms: Error code, run will not begin, or aborts.
Root cause: Set speed exceeds the rotor maximum, an imbalanced load, the lid / door not locked, an unapproved rotor, or a drive / control fault.
Will not reach speed / excessive noise or vibration
MediumSymptoms: Slow spin-up, rumble, or vibration.
Root cause: Load imbalance, worn drive / motor bearings, a worn drive coupling, or (older units) worn motor brushes.
Vacuum will not be achieved (ultracentrifuge)
HighSymptoms: Vacuum-fault alarm, long pump-down, run aborts.
Root cause: Vacuum-pump wear (low oil / worn vanes), a chamber / feed-through seal leak, or a valve fault.
Lid / door will not open / lock
MediumSymptoms: Lid-lock error, will not open after a run, or will not lock to start.
Root cause: Lid-lock solenoid / switch fault, or a run still in progress.
Speed / temperature inaccurate
MediumSymptoms: RCF / RPM or chamber temperature does not match the setting.
Root cause: Tacho / speed-sensor or temperature-sensor drift.

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
Error Codes
Extracted directly from this unit's own service manual.
FRSFRS integrity is not established within 10 seconds after the pump is turned on
Check and clean door sealing area and door gasket. Wipe excess moisture from chamber. Make sure that elutriator port stoppers are in place at left side of door seal.
IMBALRotor load is imbalanced
Make sure that the tubes are loaded symmetrically in the rotor. With swinging bucket rotors, lubricate the buckets according to the rotor manual instructions. Unlubricated pivot pins can prevent the buckets from reaching horizontal position, which can cause imbalance.
SPEEDSpeed control system is malfunctioning
Call Beckman Coulter Field Service.
DOORDoor is not latched properly or interlock is out of position
Open the door and close it firmly; press [CLEAR] to stop LED from flashing. Restart the run.
SYSThere is a problem with the system control software, EPROM, or RAM
Call Beckman Coulter Field Service.
POWERMomentary power failure; rotor does not come to a complete stop
Press [CLEAR] to stop LED from flashing.
DRIVEDrive system malfunctioning (for example, over current, over/under voltage, components over temperature)
Call Beckman Coulter Field Service. Before trying to open the door, listen carefully and make sure that no sound is coming from the chamber (indicating a spinning rotor). Follow the directions under ACCESSING THE ROTOR IN CASE OF POWER FAILURE.
REFRRefrigeration system malfunctioning
Call Beckman Coulter Field Service.
TEMPSystem temperature goes above +4°C or below –2°C of set temperature after set temperature is reached
If the rotor temperature does not affect your protocol, press [CLEAR] and let the run continue. Otherwise, press [STOP] and call Beckman Coulter Field Service.
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: Will not start / error at start
- Confirm the set speed does not exceed the fitted rotor's maximum and the rotor is approved and correctly seated.
- Rebalance the load - opposing positions evenly loaded.
- Confirm the lid / door latches and locks.
- Look the fault code up in the manual and follow the remedy.
- Functional-check after any repair.
Symptom: Vacuum will not be achieved
- Inspect the chamber / feed-through seal for damage.
- Check the vacuum-pump oil and change it / the O-rings per the schedule.
- Run a leak / vacuum-decay test.
- Rebuild or replace the pump if vacuum is still weak with a good seal.
- Confirm the rotor chamber is clean and dry.
