Component naming convention: R1 = Rig 1, P = Pump, V = Valve, G = Gauge, CH = Chamber, RP = Rotary Pump, ISO = Isolation, VENT = Vent, BX = Barometric. This naming follows the VacTech component ID standard.

System States

VENTED

R1-V-ISO OPEN

R1-V-VENT OPEN

R1-P-RP OFF

Chamber at atmospheric pressure. Safe to open.

ROUGHING

R1-V-ISO OPEN

R1-V-VENT CLOSED

R1-P-RP ON

Pump is evacuating the chamber. Pressure falling.

ISOLATED

R1-V-ISO CLOSED

R1-V-VENT CLOSED

R1-P-RP OFF

Chamber sealed. Pressure holds if leak-tight.
