Hi Anna,
Quick one — our team at the Halden Seattle plant is running the Turbine X-90 units close to 6 mm/s RMS vibration and the new ISO threshold says we're still within spec. But these units are from 2005. I remember Karl Halberg said something about legacy limits being tighter.
Can you confirm what threshold we should hold on legacy X-90 units? Our vendor Kessler-Voight is pushing us to accept the newer 7.1 mm/s limit and I don't want to sign off if that's wrong.
