The original manual had a basic error table. The updated Eppendorf 5402 manual includes a comprehensive diagnostic matrix. Here are the most relevant updates: eppendorf 5402 manual updated
| Error Display | Original Explanation | Updated Explanation & Fix | | :--- | :--- | :--- | | Error 01 | Lid not closed | Lid latch microswitch corrosion. Spray with contact cleaner (DeoxIT). Replace switch if recurring. | | Error 05 | Rotor imbalance | Also indicates worn motor bushings. Spinning with no rotor? If error persists, replace bushings (Part 5402-321). | | Error 14 | Compressor overheat | Condenser coils are dust-clogged. Updated manual provides cleaning protocol: vacuum from rear, not top. | | Error 22 | EEPROM failure | Main board battery (CR2032) is dead. Replace battery, then perform "Factory Reset" (Hold Stop + Start for 15 sec). | | No Error, but not cooling | "Normal variance" | Known issue: Relay K1 on power board fails. Updated manual includes soldering repair guide. | | Parameter | Value | |-----------|-------| | Max
If you are using the original 1990s or early 2000s instruction booklet, you are likely missing critical updates. Since the centrifuge’s production ceased, Eppendorf has released several technical information sheets (TI sheets) and safety updates that supersede the original manual. RCF | 16,000 × g | | Time
If your lab has been using an old paper manual or a first-generation PDF, here is a checklist of updates to implement immediately:
| Topic | Original Instruction | Updated Instruction (Rev. 5+) | |-----------|--------------------------|------------------------------------| | Rotor inspection | Visual check monthly | Visual + dye penetrant test every 6 months | | Lid lock test | Not mentioned | Perform microswitch continuity test before each use | | Temperature calibration | User not advised | Use external Pt100 sensor quarterly; offset adjustable via rear panel | | Emergency lid release | Mechanical pull cord | Mechanical pull cord + magnetic override code (in addendum) |
