The lid up operation took place on Jan. 30, 2023.

The system was not energized well ahead of time to allow to "warm up", as is usually done.

Starting Master Synchro value: 62

The Master Synchro was jogged to a value around 2 prior to starting, to allow it to lag behind the jacks.

When first starting: after a few attempts to raise, it was determined that the master synchro value needed to lag behind the other synchros more than initial suspected. This was changed, and the system operated smoothly for a short time.

During lid travel, station 5 and station 11 both caused trips and needed to be manually jogged to match the rest of the stations. The system was restarted, and more trips occurred. Stations 7 and 10 were adjusted as well. Eventually, after adjusting a few stations, the lid travel smoothed out and no more issues were observed for the remainder of the operation.

The system was stopped at approx. 3 inches of travel (synchro count 5255) to inspect the seal, etc. Everything OK.

No major issues with any jacks. No overheating observed.

Jack 11 showed occasional noise spikes on readback (this happened in 2021 and 2022 as well - suggest replacing this station's synchro next).

When finished, the limit switches toggled as expected, and the gap was measured at 46.5" (correct value).

Ending Master Synchro value: 47388

The attached spreadsheets show all synchro values before and after the operation, as well as jack station infrared heat measurements.

Start time: 9:23 am
End time: 10:53 am (includes gap measurement, etc. - actual lid travel finish was a bit earlier)
Total time to raise was approx. 1.5 hr.
