Dear Dave
Thanks for looking into the same and setting to new values.
We must look into and define the path forward moving ahead.

After resolving the Z support alarm I called the counting house. They told me that there were still alarms and gave me a signal name.
I found this to be the strain gage on one of the Upstream Hex Beam (sector 4) and the force was tickling the high limit of 5000 lbs.

I looked at the data logger and found that this too had been higher and had been alarming on and off Since Oct 2024 See plot
I increased the alarm setpoint value to 5300 lbs

This too should be further investigated...

Dave
