Type-A

  • Repaired the thermometer cable in IX.
  • Cleaned the cross tube of EXV with the vacuum cleaner.
  • Investigated the BF V2 LVDT in EX. The noise level may be increased due to the large DC position.
  • Repaired the LVDT driver for the GAS filters in IX. The original main card was noisy.
  • Recovered the yaw FR in F0. The helix-coil spring was too loose.
  • Investigated the actuator of the BF damper. The cable from the Dsub connector was touching the bracket for the secondary coil.
