  2158   Tuesday, October 27, 2020, 11:46 Matthew GareauNorth Hot-CellRepair  Ratcheting repair issues with both left and right master

 

The were issues with both left and right master ratcheting;

- the left handle was getting stuck in a close position when there was a higher ratcheting tension added

- the right ratcheting was not tightening preventing proper use of the manipulator


Chad and myself were able to identify a missing set screw for the tong cable.

Once this was added the issue with the left master ratcheting seems to be solved.


Lubricant was added to the left master ratchet and this seems to solve this problem as well.


There was also an observation of missing set screws on the spare manipulator for attaching the wrist to the ratcheting handle, which will need to be ordered and attached.

  2149   Tuesday, September 29, 2020, 12:12 David WangITERepairTM4 TM4 steerers staus after" left " grounding issue, and first stage investigation

Left (short) is switched with bottom. So on module:

"Top" is still top.

"Left" is bottom in module actually

"Bottom and Right" is Left and right in module actually.

 For the connection in ITE:

Left  cable is connected to "left" ( bottom  in module actually)

Top cable is connected to " Bottom and Right"( left and right in module actually)

Bottom and Right cable is connected to "Top" which is top in module.

Frank and I removed the panel, disconnected the "Left"cable  inside panel,  and checked  cable to ground resistance. "Left "is dead short to ground on ohmmeter check still. So the short could be on cable or inside source tray.  Further investigation is planned to confirm the short  location.
