4.31 Bearing Sensors
4.31.1 Bearing Sensor Function
Bearing sensors feed back real-time shaft orbit information to the bearing control loop. Refer to
"Figure 4-279 Bearing Control Signal Flow" on page 219.
4.31.2 Bearing Sensor Connection
The Bearing Sensors are connected internally to the Bearing Sensor feed throughs located above the
front and rear bearing power feed throughs. The bearing sensor feed throughs are connected to the
bearing sensor cables which connect to J9 and J10 on the Backplane. Refer to "Figure 4-290 Bearing
Sensor Feedthroughs".
