Turbocor Compressor Problems

[brownmichael]

I am trying to trouble shoot a danfoss turbocor compressor. I was lucky to be able to connect my laptop to the compressor.
The initial problem is that the compressors does not get away. After following the instructions in their manual. I was able to do a bearing calibration and they seemed to be ok. I was able to levitate the shaft and spin it at an RPM of around 2,500. As soon as i took the RPM up manually (higher than 2,500RPM) The compressor went into fault.

Whenever i get to the end of the book it tells me to contact turbocor in America. Has anyone else experienced this fault? Or can anyone else supply me a contact to talk to turbocor about the compressor. There website never has any contacts.

By the way the compressor is on a flooded system and i have also identified that it is not full of liquid.

Very little info here. I would be happy to help you but from your description it can be anything.

After looking through the alarm log it shows numerous bearing faults. I am able to do a bearing calibration on the computer and nothing is highlighted as being a problem. I was able to levitate the shaft and spin the the shaft to a speed of 2500 RPM. As soon as i took the shaft speed high manually it went into alarm.
