Dear all,
The Motion loop would be updated now in order to fix names problems with PSLITs motors. In few minutes would be reachable again.
Than you! |

Status Interlock Tests Today, posted by Tobias Haas on 13 Apr 2017, 13:19
|
Radiation Interlock Tests are finished. Tunnels XTD9 and XTD10 up to the fence at the dump can be accessed right now. Magnet current interlock tests
still takes a bit of time (ca. 1h). Once this is also done, I shall post a note |

EtherCAT loop broken for Vacuum loop, posted by Alessandro Silenzi on 13 Apr 2017, 10:15
|
The EtherCAT loop for the vacuum PLC is interrupted at crate 1.6 (XTD2).
This triggered all Beckhoff Terminals default behaviour from this point on (i.e. Valves Closed, Digital Outputs low, etc.).

XGMs in loop, posted by Jan Grünert on 11 Apr 2017, 22:36
|
Both SASE1 XGMs (in XTD2 and XTD9) are now again in the Vacuum Control Loop, their vacuum being controlled by Beckhoff/karabo. This works fine.
Therefore: DO NOT FOOL AROUND WITH THE VACUUM LOOP !
Since we all cannot enter the tunnel XTD2 in the next two days, it's agreed that the Vacuum Loop is NOT going to be touched at all, since |

Beam Stopper and V0 valve test - SUCCESSFUL, posted by Raúl Villanueva-Guerrero on 11 Apr 2017, 18:38
|
The Interlock conditions for these two components has been positively tested but not exhaustively done:
The triggering of both via the actuation on the Fast Valve----------------->DONE and OK
Their triggering via HV down of each of the 6 ion pumps------------------>Partially DONE and OK: Partially means that only one of the pumps |

Fast Valve Test - SUCCESFUL, posted by Raúl Villanueva-Guerrero on 11 Apr 2017, 18:29
|
The Fast Valve test has been positively tested.
It has been consider that the signal on the EPS to open again, should be also available in the vacuum loop. Still this need to be further discussed.

XTD2 Complete Gas Section (DPS-XGM-DPS) Isolation Interlock tested - SUCCESSFUL, posted by Raúl Villanueva-Guerrero on 11 Apr 2017, 17:44
|
The interlock definition for complete isolation of the whole section based on high pressure signal has been successfully tested.
DPS (Upstream and Downstream) are now fully "controlled" by Karabo.
XGM has been reported by J. Grünert that it will be re-integrated during the evening. |

EPS loop, posted by NEREA JARDON on 11 Apr 2017, 15:38

Dear all,
The EPS loop would be stopped, in order to correct some issues with the hardware in Rack 1.1 and Rack 1.5 in XTD2. We will upload it as soon as
possible and I will post a new entry here when it is running again. |

Big issue with XGM vacuum in both XTD2 and XTD9 !, posted by Jan Grünert on 11 Apr 2017, 15:24
|
Both XGMs were and are on manual control (but the remote cables into the turbo pump controllers remained plugged in as usual) = both XGMs are "out
of the VAC loop".
In XTD2, I saw around 13h that both turbos were off (0 Hz) and the pressure was at 10E-4 mbar !
The
green light above the ON-button was flickering.
I switched parameter 023 (Motor TMP) to ON and restarted both pumps. The green light above the ON-button

Script to install the latest karabo, posted by Alessandro Silenzi on 11 Apr 2017, 13:48 
|
Please find in attachment the dowload bash script for the latest Karabo.
if your system has a "karabo" directory, this script will not overwrite it, but the update will fail.
In this case, remove or rename the karabo directory. |

Dear all,
Sorry for disturbing again, I will do a small update to put one missing coupler in the hardware configuration in rack 1.18, the loop would be running
again in few minutes. |
