TROUBLESHOOTING
Common problems, causes and fixes
Imbalance alarm or vibration
Likely causes
- • Unequal tube masses
- • Tubes not placed opposite each other
- • Missing bucket
What to do
- • Re-balance tubes by mass
- • Load symmetrically
- • Fit all buckets, even if empty
Supernatant still cloudy
Likely causes
- • RCF too low
- • Time too short
- • Fine colloidal particles
What to do
- • Check the method RCF and radius
- • Increase time within method limits
- • Use a higher-speed rotor or filtration as allowed
Lid will not open
Likely causes
- • Rotor still turning
- • Power failure
What to do
- • Wait for the rotor to stop
- • Use the manual emergency release only after confirming the rotor has stopped
Does not reach set speed
Likely causes
- • Worn motor brushes or drive fault
- • Rotor not recognised
What to do
- • Call service
- • Check rotor seating and identification
Tubes cracked
Likely causes
- • Tube RCF rating exceeded
- • Old or solvent-damaged tubes
What to do
- • Use tubes rated for the RCF
- • Use solvent-compatible tubes and replace old stock
