The instructions for replacing the motor start with "Remove the rotor assembly by unscrewing the thumbscrew (101088), set them aside as you will need to put them back." The picture included shows the rotor just lifting off. I'm pulling, hard, this rotor is not lifting off. Is there something I'm missing? The thumbscrew it refers to is part of the cover you place over the microhematocrit tubes once you're going to run the centrifuge.
We've got an old eppendorf 5810R that was manufactured in 1998. It looks like it has a slightly cooked Finder 65.31 relay. I'm trying to find more information about the relay as it is a 110V AC relay. I can't find any other numbers on it.
The centrifuge powers on but when the compressor kicks on it trips the internal breaker on the centrifuge.
I'm thinking it's potentially a relay or capacitor problem. When I opened it I noticed the Finder type 61.31 relay. Thought this might be a good place to start.
Anyone have any ideas. Do these cook themselves eventually. I didn't see anything about it in the Eppendorf 5810R service manual.
our 5810R, is working fine if we set it up to 3000rpm, but when we set it to 4000, it is reaching 3500 rpm and then giving imbalance error and stop, even if it works empty without any container.
