Hi Vincent,
I'm working on adding some additional controls to GunAlign so you can "turn on" your high voltage, but I just realized that if you have a column condition file (*.PCC) saved from one of your runs (usually saved to the C:\UserData\ColumnPCCData folder), you can use the Conditions menu in GunAlign to load it to the instrument.
I think that the ACCS command (which turns on the HV) will get sent in that case.
The values for sending the ACCS command are: 0 = off, 1 = on
By the way, one can read the gun status using the Monitor.exe utility as seen here:

Try and see see what state the gun is in first.
