 Thu Jan 16 22:06:39 2020, tions applied to solve this issue :Martin Will, Thierry Le Flour, Telescope Operations, Software, Semi-Expert Drive GUI not connecting / MOS server not working, Fixed 
|
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. |

|
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. |

|
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. |

|
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 |

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. |

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.

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 |

|
After pointing Polaris yesterday, it seems that the zero position of the telescope was incorrect but It's never had been calibrated (zero was equals
to parking position towards center of tower).
So I shift the zero position of telescope by 0.869°. |

During this weeks we solve this problems:
_ Park In: Sometimes the final locking position was too limit and the "In Position" sensor was lost during the locking witch put the
sytems in bad state vs safety constaint (we can't unlock if the sensor In Position is not active). So now the final poition is now adjusted dynamically |

new session of high speed drive tests after issues with Power Supply.
Tests of emergency stop (with a speed at 25% and 43 % GRB speed) with a modification of the jerk value from 0.08 to 0.2 ==> OK
Tests
of azimuth movements : (-90 to 270 degres)
at 60% of GRB speed. ==> Ok for 6 movements
at 80% of GRB speed
Ok |
