[X-front] * Suspended the filter chain from the TF. * Attached two cross tubes and four feedthroughs onto the top chamber. * Cabled from the upper small hexagon to the feedthroughs. * Replaced the guide clamps for two blades with thin guards. Compressed the blades by 3~8mm respectively. * Released the keystone of TF. The height of keystone was too low without additional load. Frequency was 1.4Hz (too high). * Repaired the thread hole for the hook screw for the SF damper. * Attached the EQ stop anchor. Adjusted the horizontal position of the EQ stop. * Checked the LVDT signals. Found the F1 keystone touching to the secondary coil. When the F1 sit on the release sensor, it was free. * Set the LVDT drivers to the rack. Calibrating the LVDTs for the BF damper. |
