Tuesday, February 08, 2022, 11:39, Adam Newsome, Cyclotron, Development, Radiation Survey - sampling rate error
|
When attempting to perform the radiation survey, the program displayed an error at startup stating that the software was not able to keep up with the
incoming hardware samples, and suggested to increase sampling rate or buffer size. The default sampling rate of 500 ms was not used - rather, 100 ms was
used. No issues were observed with this rate. As far as I am aware, this issue had not occurred in the past, and the cause is unknown. |

was due to the "OP LIMIT" interlock - the "OP LIMIT" pushbutton on the console was illuminated in red, and needed to be continuously
held down in order to operate the radial in/out motion buttons. |

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 |
Thursday, February 08, 2024, 08:50, Adam Newsome, Elevation Jack, Maintenance, Elevating system - station 10 motor contactor issue
|
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 |
