Jason Kapalka | T-Hall Crane | Development | Installed surge protector |
Background: On 2019-06-25 a Pri VelFdbk Loss fault was discovered on the Main Hoist East Drum South Motor of the ARIEL Target Hall Crane. The crane was used previously on 2018-08-22 without incident. The main hoist of the crane was unavailable until the Hugo Lapointe (Automation Technician) from the crane manufacturer (REEL-COH) replaced the Allen-Bradley 20-750-ENC-1 Incremental Encoder board in the 800VFD with a new one, and replaced the Motrona cross switcher and splitter with a terminal block on 2018-08-22. The cause of the damage to the board and splitter could not be determined. Hugo Lapointe recommended that a DEHNguard DG MU 3PD 480 3W+G R (908355) pluggable surge arrester be installed in order to protect the system from voltage surges, which may of been the cause of the fault on 2019-06-25. Datasheet for surge arrester is attached. Sylvain Raymond said that the device should be installed downstream of the motor disconnect switch and fuse in the electrical enclosure.

chad fisher | T-Hall Crane | Development | Jason's Remote Crane Test Boxes |
On Tuesday, February 14th I finished modifying Jason's boxes for the remote crane tests by adding shelves to mount cameras... Apart from given the edges a quick sanding (so no one gets slivers)...which I will try and do tomorrow. |

chad fisher | Hot Cell 1 | Repair | Leak Rate Testing |
On August 1, 2023 HC1 was pumped down to -1200 Pa (gauge) and then valved off to test the leak rate after turntables had been sealed with backer rod in the gaps.
The sealing with backer rod allowed the cell to reach the test pressure of 1000 Pa. The cell pressure equalized within 30-40 seconds which is an improvement but still not sufficient to meet the goals we have set.
Next step is to pump down to -500 Pa and use smoke generator and perform thorough investigation to identify any leaks. |
