It was noted on Nov. 9 that a squeaking noise was present when the turntable was rotated CCW with a module present.

 

Upon inspection, it appears the issue could be due to drive chain misalignment and improper tension. Furthermore, it was noted that a shaft collar on one of the existing chain tensioners was broken (a replacement was ordered).

 

Repairs will be performed on Nov. 19 to resolve these issues by re-aligning the chain, and resetting the tensioners. The turntable will be tested. This e-log will be updated once the work is complete and the system is returned to a functioning state. See Work Permit I2021-11-09--3

 

Edit, Nov. 19: the aforementioned repairs were completed and the turntable has been tested and is operating correctly. No squeaking noise is present. It is suggested to increase the diameter of the two chain tensioner shafts (and thus modify related bearing and shaft collar components) in order to prevent bending of the shaft which was observed. This will be done in the near future.

 TM#2 with C#3 has been moved from the north hot cell to ITW. Also for the up coming site wide power outage, the ISAC Target Hall crane has been turned off and powered down, also the remote crane console has also been power down as well so that mean no ISAC TV for a few days.

  2250   Thursday, September 23, 2021, 19:04 Adam NewsomeSpent Target VaultDevelopment  Mini-Storage: Remote Capability

Remote capability was added for the mini-storage door control. The control signals originate from the Opto 22 Module box that is used for the SMP remote control (this is located just above the storage vault).
The controls signal assignment document has been updated and can be found in C:\PDM Vault\PDM_Vault\_models\isac\isac1\wpn-3919 - safe module parking\Electrical

In order to operate remotely:
- Plug the mini-storage control box power cable into a wall outlet (adjacent main storage vault, under stairs)
- Plug the motor output cable into the mini-storage door motor
- Unplug the local pendant from the box
- Plug the cable that comes from the remote module box into the connector that the pendant was plugged into (M12, 5 pole Murr connector)
- Using the remote control program from the ISAC RH control room, click on the Mini-Storage option and then click buttons for open and close to operate the door (note: it is important to verify both opening and closing functions work before attempting any remote operation).

Remote and local functionality have been tested and verified working.

It is recommended to mount the mini-storage control box in a convenient area near the mini-storage (possibly on the wall adjacent the main storage vault).

Please contact me if you have any further questions.
