| [IYV] 1.Assembling Pre-isolator We prepared for pre-isolator installation. - Magnetic damper ring was placed on F1. - EQ-Stop structure was extended to the top ring. - We installed bridge frame on the scaffoldings. - We combined IP and TF. We replaced the top filter blades. - In order to replace the blades,we removed all blades from TF. - We bent 6 new blades and attached it to the Top Filter. We attached the following equipment to the PI. - Connectors, Auxiliary blade (for F1 FR), Fishing Rod for TF. But FR was not completed due to lack of parts. 2.Installing Pre-isolator - We put the pre-isolator on the bridge frame and hanged F1 or less. Result of hanging F1 or less Height of TF keystone: 1mm Height of F1 from EQ-plate: 67.5, 79, 80 Distance between bottom of IP and Top-ring: 5mm (initial 8mm) TF was able to lift F1 or less. 3.Calibration of the LVDTs for BF damper. --- |
