Hi Tyler,
I collect below few things would be nice to clarify
on the slow control monitors:
- is the "Sensor Location" map updated for RICH2 ?
we do find sensors present both in the EPanel and
N2 volume (i.e. H4, H6, H13), and labels and values
different from "Sensor and limit monitoring" list.
We would need to know the location to trace the
possible difference in the trends during the test.
- in strip charts INTLK temperature shows often
overflow values that appear to be fake (we do
not see in "Sensor and limit monitoring" and no
interlock shutdown occurs). Still they are annoying
while comparing the trends and in some cases (T3)
they hampers any visualization. Do you know the
origin ?
- in strip charts there is a mismatch in time between
the SSP and INTLK temperature measurement: the INTLK
appears with a 10 minutes delay. Not a big issue,
but still surprising.
Thanks, Marco.
