We are operating LM6000PC SPRINT with Bently Nevada Vibration Monitor. For sometime now we keep receiving wideband vibration alarm on the TRF and CRF. I understand LP vibration as the consequence of LP shaft either at the TRF or CRF end same for HP. I want details on the wideband.

I assume you have a Bently 86517 accelerometer interface module. If so, Bently manual # 83301-01 gives some detail on wideband and troubleshooting the charge amp. We recently had a problem with spurious wideband alarms, found a ground fault on the extension cable from the accelerometer interface to the package cannon plug.
