A cable track was installed between the mini-storage vault and the silos, for the purpose of implementing a retractable cable chain (e-chain). This will allow for cables to be managed during door opening/closing, so that remote control operation of the door will be possible in the future. See Work Permit I2021-08-11-2 (Aug 11)

Holes were drilled into the motor mounting plate (IRH2089) to allow for mounting a limit switch on the plate. See Work Permit I2021-08-17-7 (Aug 17)

Preliminary testing was completed in which the e-chain was fixed to the door with a C-clamp. Local and remote functionality were checked, and limit switch functionality was verified. Everything is working as expected. A final test will be conducted once the e-chain is fixed to the door and cabling routed through it. See Work Permit I2021-08-19-1 (Aug 19)

The e-chain has not yet been fixed to the vault door - holes will be drilled in-situ after preliminary testing is complete to confirm positioning.

 Edit [2021-09-23]: the installation is complete and has been tested.

The West Entrance Module has been moved from the South Hot Cell to the West Target Station.

 The spent Ta#62 target along with 2A2M19 were placed in pail #256 and placed in spot 7A of the spent target vault. See attached PDF for vault details.

 The spent UC#34 target was moved from the north hot cell to the spent target vault. See attached PDF for details.

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.

ITE IG1S cable end connector replacement has been finished by Roy Huang.

 The spent SiC#41 target has been placed in pail #260 and placed in spot 5B of that spent target vault. See attached PDF for details. 

 Ta#56 in pail #169 was repacked and placed into #269 and was placed in the mini vault at the back. It was 3.86mSv/hr upon removal from the NHC. See attached files for details.

 The spent C#3 target has been moved from the south hot cell to the spent target vault it was placed in pail #270 and put in spot 2C of the vault. See attached PDF for more details.

 Ta#53 was repacked and placed in the mini vault it was changed from pail#164 to pail#262. See attached PDF for further details.

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.

 Ta#57 was repacked and placed in the mini vault. The pail was changed from #174 to #263. See attached PDF for more details.

 The spent targets SiC#38 and UC#29 have been removed from the spent target vault and placed into the mini storage. See attached PDF for details.

A rotary limit switch was installed, attached to the shaft adjacent to the drive motor for the vertical drive system. This limit switch is not yet wired to the control system and operational - this will be done at a future date and the e-log will be updated.

Edit (2022-03-02): see e-log https://elog.triumf.ca/TIS/RH-ISAC/2309

An issue was observed in which the target hall crane was not functioning: the N-E-S-W and up/down motions did not work, however the rotation motion did work. These symptoms were similar to what was observed in the past under https://elog.triumf.ca/TIS/RH-ISAC/2039 and https://elog.triumf.ca/TIS/RH-ISAC/1845

The crane control console was not powered (i.e. pressing the ON/OFF buttons when the selector switch was set to remote mode, even when safety conditions were met, did not enable/disable remote functionality). The power supplies were checked and everything appeared to be powered as would be expected, except for items which depended on the main contactor (O-K1) being energized. This contactor needs the PLC to be in an operational state, fault-free. The PLC was checked and the red fault light was flashing. The battery light was not on (i.e. battery was OK).

The program was re-downloaded to the PLC. During an attempt to go online with the PLC, error code 0004h appeared (see attached image for description). This is an unfamiliar error code - typically the aforementioned symptoms arise due to a battery failure and the program being lost. In this case it is uncertain at this time what the cause of this fault is. It will be monitored in the future to determine if it occurs again, and further investigation will be performed.

After re-downloading the program and placing the PLC in RUN mode, the crane was fully restored to its operating state - the main contactor was able to be energized once again. The crane was put into remote mode and a brief functionality test on the motion axes was performed: OK.

The spent UC#35 target has been moved from the south hot cell to the spent target vault. It was placed in pail #264 and put in spot 6A of the vault. See attached PDF for more details.

We loaded UCx #29 , SiC #38  , Ta#53, Ta#56 ,and Ta#57 from mini storage  into F308 flasks.  Later, the flasks are transferred from TH to B2 HC service area. In TH, Working area and Mini storage are cleaned and surveyed.  Tools are cleaned and surveyed as well. No contamination.   Mini- storage is empty now.

Frank and I replaced ITW Exit module 1 side square service panel o-ring seal. Also, The target module pit top flange o-ring seal in ITW pit is replaced.  

 The spent UC#36 target in the north hot cell has been removed and placed in the spent target vault. See attached PDF for detail note that the PDF does not show that spot 2B is occupied by the 2A3M20 pail.

Tom Gauss inspected  two target module lifting frames ITA0494-1997-01 and ITA0494-1997-02.. He certified the use of these two frames. Inspection tags have been issued and attached to frames. He has inspection record on them. See attachments.
