Tuesday, October 27, 2020, 11:46, Matthew Gareau, North Hot-Cell, Repair, , , 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.

Tuesday, September 29, 2020, 12:12, David Wang, ITE, Repair, TM4, , TM4 steerers staus after" left " grounding issue, and first stage investigation
|
Left (short) is switched with bottom. So on module:
"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. |
