IFO pressure was 2.3 mTorr this morning,
The Maglev's foreline valve V4 was closed so P2 rose to 4 Torr. The Maglev was running fine with V1 open.
This is a good example for V1 to be closed by interlock, because at 4 Torr foreline pressure the compression ratio for hydrocarbones goes down.
V4 was closed by interlock when TP2 lost it's drypump. The drypump's AC plug was lose.
To DO: set up interlock to close V1 if P2 exceeds 1 Torr
We added C1:Vac-CC1_pressure to the alarm handler, with the minor alarm at 5e-6 torr and the major alarm at 1e-5 torr.
