A review of the Suspension DMS flags has been performed. Now the thresholds have been set in order to require an intervention, either by an operator or by an expert, only if a flag becomes red. A matrix with the actions will be also prepared for the operators.

A set of thresholds on the power of the optical lever SLEDs has been added in the PAY section for all long towers. A flag becoming red would suggest aging of the relevant SLED.

  • Optical lever SLED power thresholds have been added for both IB and MC
