We went to the offloading of F0. Though we tried to move the keystone with the FR from 8400 to 4500(setpoint) in count, the keystone stopped at 7200. The keystone was oscillating and can move with the actuator.
[Takahashi, Sato]
We checked the F0 FR opening the chamber. The F0 FR has been stuck at 7200 in count (-13.5mm in keystone heigh). The upper limit switch was reset to 7560 (-13.6mm). The previous upper limit was 3910 (-12.2mm). It is necessary to shift the working point up by reducing the ballast weight on the F0.
[Takahashi, Sato]
We adjusted the working range of F0.
- Removed the ballast weight of 0.7kg from the keystone. The keystone height was changed from -13mm to -11.5mm.
- Checked the range of FR. The FR was stuck near the lower limit. Reset the lower position of limit SW at 6950 in count (-13.4mm in keystone height). The upper position of limit SW was at 3160 (-11.9mm).
- Set the keystone height to 3500 (-12.0mm).
