Progress report
General
[Miyo] As you all know, we have had trouble starting a measurement with a DGS error. In order to eliminate this confusion during the work, I make the following rules;
- First, make sure that the VIS_OVERVIEW screen is all green before you start working.
- And after working, be sure to make everything green and finish your work. This is a kindness for the next operator.
- The SDF will probably turn red as you work. This means that SDF has detected channel differences during your work. If you accept these differences, please be sure to take a screenshot and post it in klog, but you don't have to post it to revert.
That's all.
Type-A
Type-B
Type-Bp
Type-C
- Set up the old OSTM suspension in the OMC both.
[Miyo] We (mainly Ikeda-san) made Type-C guardian. Now we can use ALIGN state. In this state, we only engage the APTICALIGN with ramp time not engage the OpLev DC control according to Nakano-san's advices. klog#15578
