What is still missing is the commissioning of the AMC boxes and aligning the WLAN antennas. This is not possible because the power distribution box still has no main power. Also no main fiber connection. That still needs to be done by the LAPP people. Most importantly at the moment, that Casana is realigning all the actuators. All actuators need to be straight aligned with the mirrors so that they can be put into operation. || https://nextcloud.mpp.mpg.de/nextcloud/index.php/s/PyLe9iHxteKYPiC || [[File:20180824_161921.jpg|200px|Image: 200 pixels]] || [[File:20180824_161810.jpg|200px|Image: 200 pixels]] ||[[File:20180823_101609.jpg|200px|Image: 200 pixels]]

General Remarks, Problems & Trouble Shooting[edit]

  • On Saturday August 4 Casana helped with the installation of AMC boxes instead of Dragados to finish the installation on time.
  • On Friday August 10 only one person was available to prepare the mirrors from 9 to 12, still it was possible to prepare 7 mirrors efficiently (only with help from Casana in carrying the mirrors out of the crates). The holder plates for one CMOS camera was missing, since the bottom of this mirror is accessible after installation the mirror was installed without CMOS camera.
  • The installation of tube holders on already installed IF plates is very cumbersome. Sometimes the tube is in the way to properly install the holders with all 4 screws, and even if it is possible the access is very hard. Catwalks are of little help since they are too far away from the mirrors. For the next telescopes the special tube holders must already be installed during the IF plate assembly!
