| 2018-08-24 | Toni, Dragados | AMC Box cabling | Today we finished to install the rest of the power cables and fibers to the AMC boxes. 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. | 200px|Image: 200 pixels |  |

| 2018-08-23 | Toni, Dragados | AMC Box cabling | Today we finished to install the power cables and fibers to the AMC boxes (1,0,4,3,2,9,8,6,5) . | |||||
| 2018-08-22 | Toni, Yusuke, Dragados | AMC Box cabling | We finished today internal cabling of the last 2 AMC boxes (1,0). See the first two pictures. We also broke all power cables into the structure and placed them in front of the respective AMC boxes. As an example for Dragados (Kaplan) I installed a power cable from AMC Box 5 to AMC Box 6. See the last two pictures. Unfortunately, our work was interrupted today because repairs were carried out on the concrete below the LST1 structure. |  |

| 2018-08-21 | Toni, Dragados | AMC Box cabling | We finished today internal cabling of 2 boxes (2,5). Also all actuators of AMC boxes 1 and 0 were wired but not yet connected to the AMC boxes. Till now we finished already 14 AMC Boxes. One of the Dragados workers still has failed due to illness today and one of the two other helpers arrived shortly after noon today. |  |

| 2018-08-20 | Toni, Dragados | AMC Box cabling | We finished today internal cabling of 3 boxes (6,4,3). One of the Dragados workers still has failed due to illness today. We are thus only three with me for the wiring. !!! Today I found an actuator (Mirror -7,+7) where one of its three springs does not fit snugly against the lid of the actuator. Please check the pictuare. !!! |  |

| 2018-08-07 | Martin, Casana | IF plates & mirror installation | 1 Special IF was installed, more were not possible due to wind. Installation of missing tube holders finished. | |||||
| Christopher, Satoshi, Yusuke, Dragados | AMC Box installation & cabling | Started cabling from internal cables (box - mirrors). Finished actuator cables for 1 group (E). | ||||||
| 2018-08-06 | Martin, Casana | IF plates & mirror installation | No installation of Special IF due to wind, installation of missing tube holders ongoing. | |||||
| Christopher, Dragados, Casana | AMC Box installation & cabling | Metal bars to fix AMC boxes lifted inside dish with cherry picker. Finished installation of all 16 boxes. | ||||||
| 2018-08-04 | Christopher, Toni, Yusuke, Satoshi, Casana | AMC Box installation & cabling | All remaining AMC boxes lifted inside dish with cherry picker, secured in front of correct positions. | |||||
| 2018-08-03 | Martin | IF plates & mirror installation | 7 missing tube spacers on 4 already installed IF plates installed. Rest will be done starting Monday by Casana. | |||||
| Christopher, Toni, Dragados | AMC Box installation & cabling | 5 AMC boxes in lower half (C,7,F,B,D) installed. | ||||||
| 2018-08-02 | Martin | IF plates & mirror installation | Tube spacers for Special IF plates and for already installed IF plates assembled. All 10 Special IF plates prepared and ready for installation. 5 Special IF plates for very top already prepared some months ago. | |||||
| Christopher, Martin, Toni, Yusuke, Satoshi, Dragados | AMC Box installation & cabling | Preparation of all 16 AMC boxes finished. Lowest AMC box (E) was installed and 6 boxes (C,7,A,F,B,D) lifted into the structure close to the correct positions inside the dish. | ||||||
| 2018-08-01 | Martin, Casana | IF plates & mirror installation | Inspection of mirrors potentially damaged by falling CSS rope. One spot found, unknown if actual damage. Mirror to be exchanged. | |||||
| 2018-07-31 | Martin, Satoshi | IF plates & mirror installation | Almost all of the 10 Special IF plates prepared: level actuators, attach tube holder. Still missing tube connector plates (available Thu), attaching actuator caps, leveling fixed points. |
General Remarks, Problems & Trouble Shooting
- 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!
