Last week we put in sevice the new ALS completly modified:
_ Main System with new reducer.
_ New Speed parameters for Main System (motor is at full speed but due to reducer the spped is slow). Decceleration sensors not installed since |

|
In the late afternoon shifters noticed the semi-expert drive GUI was not updating, several restarts did not help. Checking into the issue with the drive
team connecting from remote it was found that the MOS server is not running and cannot be restarted. This issue could not be solved and will be revisited
tomorrow, Jan 17, during the day. |

|
On Dec 6, Dario, Frederic and Yuji showed to Koji Noda and Daniel Mazin how to operate the new ALS. The idea was to do an unlock and lock again, as the
weather was still bad. The automatic part went more or less OK ending in error state (excpected). We then went to EAST ALS to open the main actuator manually.
After moving the actuator manually, the status of the ALS was either locked not unlocked. We realized that secondary sensor for South part was reacting |

The aim was to observe several stars with different magnitude and check the sensitivity of the CDM. We wanted to use a semi-automatic procedure with
command sent to the drive via a script to the Acs
After we realized that the telescope was not moving after a StarTracking command we try to use the drive system through the Acs server. StartTracking |

We tracked stars at various zenith angles and changed the Az and Zd offsets, taking images with the PSF camera for each position. After Armand's
changes during the day the offset is the same for all Zenith angles.

|
Drive GUI stacked due to a wrong shutdown procedure (Jul. 27th 01-02UTC). This was simply a human error.
First, we pushed ParkIn button as usual in the end of the night. We confirmed the telescope was in Locking Position in GUI, but most probably overlooked |

Regarding the problem on the Flywheel PLC (see here), we entered UC1 under the supervision of Daniel
M. and Koji (11:16 local time).
First we checked the LEDs of the black Ethernet cable. LINK in green was constantly ON and ACT in orange was blinking. |

After finishing the normal start-up procedure, we tried to park out by GUI, but got an error (22:30 local time): "MSG_WARNINGPark_Out_TimeOut"
The Drive, FSM and Command Statuses were "Parked", "in parking Area" and "No command in progress," respectively.
We closed&reopend the GUI and "Park Out" three times, but everytime got the same error. |

Tonight, we tracked Vega to test (a correction of) the pointing offset of the Drive.
Around 22:30UTC, we tried different Az offsets of the pointing in the Semi-expert GUI, followed by taking an image with the PSF camera to see
the effect of the offset choice. |

At parking in, the telescope got stuck at 94.254°. We checked in the container that fuse Q21 went off. We did not see any errors both in the Drive
cointainer and the GUI. We texted the experts. After 15 minutes, we pressed again "ParkIn" (without having touched the fuse). After nothing happend
in the GUI, we called the experts. They authorized us to switch back the fuse. After that, still heavy intervention by the experts was needed, who finally |

When parking in the telescope, accidently hit "Shutdown" button instead of "Parkin" in Drive Semi-epert GUI. Nothing seem to happen
for minutes despite telling command in progress "Shutdown"
Texted Drive experts, they told to just hit again the correct "Parkin" button. |

When checking the telescope visually outside, while it was in the "park-out" position, a car happened to pass by from the upper road (coming
from the other telescopes). Its lights flashed directly into the camera. It seems that the road is in direct prolongation of our current park-out position.
We saw the CAM HV going down several times in the park-out position (where the shutter is typically opened) during the last weeks. Can |

Then everything fine.

When parking in yesterday, the telescope drove to the nominal position (approx. 95° zenith angle and -1° azimuth), but then it took a long time
and never showed the "park out" button again.
In the driver container, we saw two alerts to acknowledge, then the GUI indicated "telescope parked". We confirmed visually that the |

The semi-expert drive control panel uses various terms for the zenith angle: "Altitude (zenith angle)", "Elevation", "Angle".
"Zenith Angle". |
