SQZ FC ASC trigger channel changed

Daniel, Nutsinee

Both SQZ FC ASC and SQZ ASC IFO were triggered and engaged during the maintenance period when everyhting was clearly down. There was a change to FC ASC trigger point yesterday that probably was the cause of the problem but we thought it'd make more sense for the SQZ FC ASC to trigger on the FC transmission. So, we made the FC ASC triggered on FC-IR TRANS_D instead. FC-IR TRANS_D gain is set to 10, trigger thresholds on is set to 0.6, trigger thesholds off set to 0.4. The changes have been accepted in the SDF.

 

There is no good/better trigger value for the SQZ ASC IFO so we left that alone.

 

We gracefully cleared history on both ASC loop.
