As it was requested by the Bos.

It would be nice to read from the epic screen C1:Vac-state_mon.......Current State: Vacuum Normal, valve configuration

Quote:

Channel	Function	Description	Interlock

C1:Vac-P1_pressure	Main volume of 40m interferro meter	P=Pirani gauge, Pressure range: ATM-760 to 1e-4 Torr	at 3 mT close V1 and PSL shutter
C1:Vac-P2_pressure	Maglev foreline pressure	Maglev is the main pump of our vacuum system below 500 mTorr It's long term pressure has to be <500 mTorr	at 6 Torr close V1
C1:Vac-P3_pressure	annuloses	Each chamber has it's own annulos. These small volumes are indipendent from main volume. Their pressure ranges are <5 mTorr at vac. normal valve configuration.
C1:Vac-CC1_pressure	IFO main volume	CC1=cold cathode gauge (low emmision), Pressure range: 1e-4 to 1e-10 Torr, In vac- normal configuration CC1= 2e-6 Torr	at 1e-5 Torr close VM1
C1:Vac-CC4_pressure	RGA pressure	In vac-normal configuration CC1=CC4
C1:Vac-N2pres	valve's drive pneumatic	The N2 supply is regulated to 60-80 PSI out put at the auto cylinder changer.	at 55 PSI close V1, at 45 PSI close all
It does not exist yet	2 N2 cylinder sum pressure	Each cylinder pressure will be measured before the regulator and summed for warning message to be send at 1000 PSI
