Prosetter 102 -- Rotating mirror problems

[zaza826]

Hello!

I have a problem with mirror of Prosetter 102, one day it's goes to noisy.
And of caurse I stopped working...

Mirror is 750hz

1. _____
Compressor in diagnostics shows 3.5 bar (see atach)
1. This element is quit cool to touch it with finger;
2. In this tube some drops of water are appreciable;
3. In these tubes drop of water isn't present. When I turn on "test mirror" filter is opened 3 times to drop some liquids.
So, I think in this part of machine is OK.

2. _____
The temperature in room is normal. It's about 20 degree.

3. _____
Dust in room is not present.

4. _____
About my tests
I removed the Rotating mirror, put on a box and began tests.
Surprisingly but a voice wasn't.

So, when I remove mirror and turn on test, voice wasn't and when I put on its place and run test voice was.
I don't know what to think. Have you any idea about it?
