Please share your experience regarding the Axial position of 9E machine, if value is in minus figure what does it mean and if value in positive figure what does it denote? Where do the thrust act?

We do have 9E machines.In our unit one machine axial position remains in minus figure, and other machine shows reading in positive and when that (positive reading) machine is shutdown and cooled down and T/G is stopped, one of axial position goes under alarm and other one goes to danger value. Earlier there was no such issue, reading did not gone under alarm or limit.

reading is in 0.18 or 0.2 on B.N system

Your guideline will be highly appreciated
