5402 error 2


Dear Sir,

In a 5402 Eppendorf Centrifuge, Error 1 states primarily for an EEPROM error. EEPROM is a tiny memory chip that stores individual details of the centrifuge, mainly the microprocessor time base (for correct time set operations), the mains voltage (115 or 230 V, to inform and set the motor current levels), and the imbalance level adjustment for the imbalance sensor. When the centrifuge powers up, these data are readen, and if all OK, the centrifuge is ready to go. If one of them corrupts, especially the 115 or 230 Volt information, we get error 1 and no start allowed.
To check and reprogram this EEPROM we have to acess the service routine. This is done by by jumping together pins 1 and 5 of X8 conector, on the base of the electronic board, located behind the power cable panel in the back of the centrifuge. There are about 20 setting or check parameters, but usually 1 or 2 of the described above need to be reprogrammed. Please e-mail me for details: phdeletr@gmail.com.

Error 2 is Motor Tach (Speed sensor) error, caused usually if the cable pops off the electronic board. But the tach sensor itself, who stays in the bottom of the motor drive, could be broken or defective.

What is a Centrifuge?


Wikipedia says: A centrifuge is a piece of equipment, generally driven by an electric motor (some older models were spun by hand), that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. A centrifuge is also used to separate the components of blood in blood banks.The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances to separate out along the radial direction (the bottom of the tube). By the same token lighter objects will tend to move to the top (of the tube; in the rotating picture, move to the centre).

My centrifuge 5702 rotor mentions error 3


The Eppendorf manual states that Error 3 means that there was an anomaly in the speed sensing system. The corrective action is to leave the power on with the centrifuge not spinning for several minutes and the error should clear itself.

If the error persists, then the speed sensor is probably damaged, and the unit will need to be serviced by a qualified technician.

S7 error message on Beckman Avanti J-E centrifuge


follow the instruction in the procedure in the last paragraph of thi link

http://www.labwrench.com/?community.posts/threadNo/962/subject/System-Error-S7/
but i think this will reset the rotor calibrtion or configuration. my system will stop the run on rotor ja-20 at 5000 rmp; and it change the rotor id set on ja-14 t 18 at 10000rpm.

How do you work the magnetic mixer base?


you place it where you place the centrifuge but you take the centrifuge off after that you use the magnetic capsule and put the beaker on it and then put the magnetic capsule in the beaker then lock the dome in place and turn it on
