20 Most Recent Eppendorf 5402 Refrigerated Centrifuge Questions & Answers


Make sure the unit is unplugged!!!
I believe it is the lid switch. You can remove the housing and the switch is located adjacent to the latch. Test it with a multi-meter.I do not recommend bypassing the switch except to test it's operation. Serious injury can occur!!!

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:

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.

Turn it on and bring up the temperature. The pressure inside will increase as the temperature increases.

Further support may be channeled through the distributor. As with many devices, it is suggested to have mainteance and repair done by personnel trained specifically in such for the devices. There is quite a bit of information in this manual one might wade through Page 28 lists error codes and error 2 listed refers to door open during cycle.

You have a microscope with a camera in or on it? And the cord goes to a tablet computer? And "pulled up codes to download" means whet? "Pulled up"? "codes"? Did you "download"?
Most operating systems will use a graphics program to accept an image from a TWAIN device like a camera or a scanner. Perhaps you could use something like that.
I have used some different programs with cameras and scanners under Windows long ago (XP and Vista).

Without a brand name and model number or any pictures, it is not possible to guess what you have, where the light is, what wires or switches might be on it.
Sometimes it is just a simple tightening of the bulb or cleaning of battery contacts to get it fixed.
