Wednesday, February 07, 2024, 12:04, Adam Newsome, Elevation Jack, Repair, Elevating system - brake master relay fuse issue
|
It was observed when attempting lid up operation on 2024-02-06 that the brakes for each of the jacks were not operating correctly. It appeared that power
was not being applied so the brakes were stuck in the engaged state. This ultimately resulted in issues with the lid up operation.
The issue was traced to relay A1 (the master brake power relay) not toggling as expected, despite the relevant control signals being present to |

|
It was observed during lid up operation on 2024-02-08, approximately halfway through raising the lid, that the motor contactor for station 10 located
within its small motor panel stopped functioning. The symptoms observed were: entire system stopped since station 10 lagged behind (approx. 150 counts
on counter), station 10 could not be jogged locally in either direction, the control signal to activate the motor was being sent to the contactor when |

Setup of the HE 1 probe is difficult has we have no mockup of it to properly setup cameras and equipment for it. This is problem for both extraction
and installation of the probe. Also with the setup some of the broken micro switch from the HE 1 was found on the HE 1 probe jig after the jig was deconned
and moved up the B2 level. Also for setup required camera adjustment to be made with the heavy contaminated probe being very close to the person setting |
