Hi any help on this would be awesome!
Bently Nevada Card 3 is dropping out causing the 4 radial probes on the gas turbine generator to go into “Not OK” state which the PLC then see’s and issues first out 108117 – “Not safe to run to turbine with no vibration protection”
“Not Ok” clears within 30S (BN Timed OK Defeat) and unit can be put into a spin and restarted
what we have done so far:
Nuisance trips are still persisting :'(

“Not Ok” clears within 30S (BN Timed OK Defeat) and unit can be put into a spin and restarted
what we have done so far:
- Trip 1 – No change, reset restart
- Trip 2 – Reseat Slot 3 card
- Trip 3 – Replace Slot 3 blue card
- Trip 4 – Replace Slot 3 IO card below
- Trip 5 – Replace full backplane and a number of IS barriers
- Trip 6 – Replacing a common cable from the BN rack to the isolators, replaced pepper fuchs power supply on the rail powering the isolators. Checked inside JB 6 and the junction boxes at the GG and looked fine.
Nuisance trips are still persisting :'(
