View valve cycles
This mode displays the ACM 150 monitor flow schematic with the current activation
state of each Cycle Valve, as shown in
As the ACM 150 monitor progresses through its sampling sequence, you can
observe the changing activate states. The standard activation sequence is explained
in ACM 150 flow cycles
Table 1.
2-way valves shown blank, i.e. with no color fill, are not activated. In this state
they are closed and block the flow path.
2-way valves shown with green color fill are activated and open. Sample flow
passes through these open valves.
Figure
and the standard cycle timing and pressures are given in
The three graphs indicate the current absolute pressure and the
recent trend over time for Sample Cell Vacuum, Bypass Vacuum
and Sample Vacuum.
