|
Some issues were encountered with the turntable controls on the west hot cell, as a result the festooning post for the turntable was damaged. While the
post was out of commission, the turntable was operated without actively monitoring the top of the hot cell and some cables ended up catching on the limit
sensors, causing some slight fraying. The cables were duct-taped to prevent shorting for now but should be inspected and replaced accordingly in the future. |

|
The four water connections on the front end plate of the APTW that will connect to the HTV were tested for replacement with the manipulators:
The pin on these connectors were fairly easy to remove and replace with the old pin detent tool.
The pin detent tool could
also be used to manipulate the water lines while protecting the sealing face.
The horizontal VCR joint on the DRIVE BEAM CONE (ATA3674) could |

|
After a recent power cycle, the y-axis referencing was lost for the 1000 kg crane. The position readout was also incorrect, somewhere on the order of
> 30,000 mm. On 2024-11-29, A. Newsome re-referenced the y-axis. The position readout correctly reset to zero, and both +y and -y motion is functioning
correctly, but the y-axis position readout on the HMI constantly displays 0 and does not change. To be investigated. |

Thursday, November 28, 2024, 09:04, Adam Newsome, Hot Cell 1, Repair, Hot Cell turntables not rotating, access hatch not moving
|
It was reported that the hot cell turntables would not rotate and the access hatch could not be operated. The turntables' elevation motion was working
normally, and other cell functions were working.
Upon investigation, after going online with the PLC and checking the interlocks for the turntable, it was determined that motion was being prevented |

|
The APTW front end was moved into the hot cell, on the lift table, following procedures outlined in Document-244862.
The mock-up frame was transferred from the east turntable to the west turntable above the front end. The east turntable is covered with the aluminum
plate. During covering we accidentally broke the o-ring for the turntable plate flange. The new o-ring seal should be made ~1" longer in circumference |

Two tarps were installed above the hot cell roof to protect against concrete dust while testing in the hot cell.
Zip ties were used to hook the tarp onto tubing brackets on the back wall. |

|
The spacer flanges were installed on both turntables today.
See photos and information in the following DocuShare Collection: Collection-39816
Important note: the fitment was quite tight due to interference with universal joints and grease nipples. The flanges were still able to be installed |

Wednesday, April 24, 2024, 09:17, Adam Newsome, T-Hall Crane, Repair, Target Hall Crane: VFD DC bus undervoltage fault [root cause: encoder board failure on 900VFD]
|
On 2024-04-22 around 3:30 pm it was discovered that the crane's main hoist was in a faulted state. The operator (Adam Newsome) experienced the fault
after performing a safety reset and attempting to lower the hoist. There were no visible signs of any issues, mechanically. This fault had not been previously
reported by any other crane operators. The crane was previously unused, sitting idle. Note: the auxiliary hoists appeared to function normally. |

|
On August 1, 2023 HC1 was pumped down to -1200 Pa (gauge) and then valved off to test the leak rate after turntables had been sealed with backer rod
in the gaps.
The sealing with backer rod allowed the cell to reach the test pressure of 1000 Pa. The cell pressure equalized within 30-40 seconds which is an |

Wednesday, April 26, 2023, 16:06, Adam Newsome, T-Hall Crane, Maintenance, Target Hall Crane - Hoist Wire Wrapping
|
It was observed recently that the main hoist's wires seemed skewed, and there was occasionally some noise heard when raising and lowering the hook block.
It was suspected that this was due to wires having jumped in their tracks at some point. This is typically caused by side loading. It is possible that
wire wrap skew occurred during the incident outlined in e-log 46. |

Tuesday, April 25, 2023, 12:28, Adam Newsome, T-Hall Crane, Standard Operation, ARIEL Target Hall Crane - Drives Fault
|
Today while operating the crane with load, the crane stopped moving. Upon investigating, all safety signals appeared to be OK. Fault messages regarding
drive faults for various VFDs were present, which seemed to stem from an ethernet adapter card fault (see attached photo). It is unknown how this occurred,
but suspected that it was due to a brief blip in network communications or the external drive power supply control signal. It is worth noting that the |
