Simple operation. Speed, g-force and radius correction values can be entered. Values can be changed during centrifugation. Temperature range from –9 °C to 40°C, with Fast Temp function for rapid cooling of the centrifuge chamber. Standby cooling maintains temperature when not in use. Speed can be set from 200 rpm to maximum speed in increments of 10 rpm. Short Spin button. Selectable program memory for up to 34 individual user programs. Ten acceleration and deceleration rates for sensitive sample material.
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 shortly after start.
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 during a run.
Root cause: Load imbalance, worn drive / motor bearings, a worn drive coupling, or (older units) worn motor brushes.
Chamber will not cool to setpoint
MediumSymptoms: Temperature high during a run, or slow to pre-cool.
Root cause: Compressor, condenser fan, low refrigerant, or a temperature-sensor fault.
Lid / door will not open or 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 winding down.
Rotor / bucket wear or corrosion
MediumSymptoms: Visible corrosion, cracks, or a bucket that will not swing; imbalance trips.
Root cause: Rotor / bucket ageing - a safety-critical wear item with a use-life limit.

Error Codes
Extracted directly from this unit's own service manual.
No rotorMissing rotor. Insert the rotor.
Missing rotor. Insert the rotor.
Close lidCentrifuge lid not closed properly.
Close the centrifuge lid firmly.
Lift lidThe centrifuge lid cannot open automatically.
Lift the centrifuge lid manually.
IMBALThe rotor is asymmetrically loaded.
Load the rotor symmetrically (see p. 26).
ROTORThe rotor is not fastened sufficiently tight.
1. Tighten the rotor nut (see p. 26). 2. Check the rotor cone and motor shaft for grooves and damage.
SPEEDNominal speed too high for rotor.
Enter the appropriate nominal speed (see p. 65).
change rotorThe maximum service life of the rotor has been reached.
Contact Technical Service.
Temperature display flashesTemperature deviation from set value: ±3 °C.
Check the settings. Wait until the set temperature has been reached. Check unhindered air circulation through the air slots. Thaw ice or switch off the centrifuge and allow it to cool down.
OvertempTemperature deviation from set value in the rotor chamber: ±5 °C.
Check the settings. Check unhindered air circulation through the air slots. Thaw ice or switch off the centrifuge and allow it to cool down.

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 mains power, the mains switch, and check the instrument fuse / circuit breaker - replace a blown fuse (a second blown fuse means an internal fault).
- Confirm the lid is fully closed and the lid interlock is engaging.
- Confirm a speed and time (and an approved rotor) are set.
- Note any displayed error code and look it up in the manual's error table.
- Re-balance the load if an imbalance is indicated.
Symptom: Lid will not open
- Confirm the rotor has fully stopped and mains power is present.
- Press down on the front of the lid while pressing the release button.
- If a power failure, use the mechanical emergency lid release per the manual.
- Inspect the lid-lock solenoid / latch and its micro-switch.
- Replace a jammed or faulty lid-lock assembly.
Symptom: Excess vibration / will not reach speed / noise
- Stop and re-load the rotor symmetrically - opposing positions equally loaded, all carriers fitted.
- Inspect the rotor pockets and chamber for debris or a broken tube.
- Confirm the rotor is fully seated and not corroded or cracked (retire per its use-life log).
- Turn the rotor by hand and feel the drive bearing; on belt-drive units check belt tension and, on older units, the motor brushes.
- Verify speed with a tachometer after any drive work.
