Operating the 5402—as outlined in its classic operating instructions—is a sequence of careful steps that every lab tech learns:
| Symptom / Error Code | Possible Cause(s) | Recommended Solution(s) | | :--- | :--- | :--- | | | Power outage, device not supplied with voltage | Check mains/power fuse of the lab and the mains/power cord. | | Cannot Open Lid | Rotor still running, mains/power outage | Wait for rotor to stop, then open. If power outage, use emergency release. | | Device Does Not Start | Centrifuge lid is open | Close centrifuge lid. | | Device Shakes on Start | Rotor is asymmetrically loaded / imbalanced | Stop centrifugation. Load rotor symmetrically, then restart. | | Temperature Display Flashes | Device hasn't reached set temperature (>3°C difference) | Wait for device to reach set point, or pre-temper with FastTemp function. | | Error 02 (Rotor Shuts Down) | Rotor imbalance, over-speed detection, or sensor issue | Check loading balance; contact technical support if issue persists. | | "balan." Error | Rotor imbalance or missing leveling foot | Check sample balance and inspect centrifuge feet for stability. | | Error Code A | Temperature sensor failure | Replace temperature sensor; contact Eppendorf for parts. |
