We changed the HIGH/LOW values of the PMC_TRANS.
The edited file was updated on the svn.
Since the PMC_TRANSPD was replaced behind the pzt mirror (see the entry), its nominal value were reduced to something like ~1V from the previous value of ~2V.
In the medm screen C1PSL_PMC.adl the PMC_TRAN always indicated red because the value were low compared with the previous one.
We went to /cvs/cds/caltech/target/c1psl, then edited psl.db
- Here are the new parameters we set up in the file.
grecord(ai,"C1:PSL-PMC_PMCTRANSPD") {
field(LOW,"0.98")
field(LOLO,"0.93")
field(HIGH,"1.15")
field(HIHI,"1.3")
}
- - - -
These values are based on ~4days trend of the PMC_TRAN.
Then we manually updated those numbers by using ezcawrite in order not to reboot C1PSL.
So now it nicely indicates green in the medm screen. |
