Please check your vibration probe loop. On which particular vibration it is tripping? Usually they don't configure trips on radial vibration in the bearings. Can you confirm which one is this one? Sometimes, the extension cable between probe and the proximitor can get burnt or damaged due to exhaust temperature exposure resulting in high/erratic vibrations.
