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.

 by "enable staging" button. MP3 has to be turned off-on to open WPV1

 The cooling manifold for the conditioning station high power water cooled lines has been returned. The cooling package can once again be operated

Rob walker has flushed and refilled the primary side of the system (note the water still looks nasty). This morning the primary side of system needed to be bled as there were air pockets. Also TK2 had reached its low point and needed to be topped up.

 The cooling package and vacuum was stopped today at 9:26 so the module can be move.

 The cooling package was started at 10:00 today. See attached picture. There is another snap shot at 10:03.

 The conductivity of the cooling package is above 5Mohm which is the minimum limit for the PS. This was achieved at 11:55. See attached picture.

 Cooling Package was started at 9:25 this morning inlet conductivity is 0.08 Mohm at 22.9C. Resistance reached 5.33 Mohm by 11:30

 The electrical connection have been made and cooling package was started at ~10:50am today

 Some reboots will be done.

Containment box has been removed from TM2 in preparation for source tray removal. I will walk Aaron through removal of the optics tray today also.

the containment box has been reinstalled onto TM3. After electrical checks it is ready to move to the conditioning station...for electrical tests.

The containment box has been removed from TM4 in prep for the IGLIS wiring job.

First thing I entered into the NHC to install to the target kart mounting clip, and remove excess tools and materials from the hotcell

After the TM3 without a target was lowered into the NHC.

Once inside, with the use of the manipulators, I was able to remove the containment box door, place it on the swivel arm, move the arm out of the way, after the door was return to the containment box and reattached.

The containment box cover has had all  the bolts installed and all bolts were checked with a mirror. TM3 has been raised and is ready for the last electrical  test before  it goes to the conditioning station.

 The containment box has been removed. Tomorrow the wiring harness will be installed.

Containment box has been removed in preparation for wire replacement.

TM4 has been reconnected to ITE after the module moving. The roughing is started . The water will be supplied to ITE after  testing  the water  pumps . The water interlock check will be done on next week also.

When the Containment Box was opened today by Chad for a target change, we found the conductor insulator block B (ITD0054) to be broken close to the right TGHT terminal. Chad was nevertheless able to remove the target. See DocuShare and attached file for photos.

An attempt to replace the insulator will be made tomorrow with a spare.

A small sticky piece, likely off plastic material, was found next to the left main source tray insulator. The piece was removed from the Containment Box. See link above and attachment for photos.
