Vacuum Pumps
Two field-replaceable pumps provide a redundant vacuum source for the transport and sample
flow system. One pump in the system draws vacuum while the other is idle. The pump exhaust
connects to the manufacturing facility central toxic exhaust system.
Note: The exhaust line from the Vertex Edge should not exceed 50 feet.
The pumps are located in the bottom of the Vertex Edge System cabinet on a sliding plate to
help disconnect the tubing for ease of maintenance. Three cooling fans circulate air over the
pumps.
The Vertex Edge System draws cooling air in through a filter mounted on the pump module
access door.
Multiple Gas Monitoring
A Vertex Edge System equipped with Analyzers can monitor more than one gas (or groups of
gases such as hydrides or mineral acids) at a location.
Each Vertex Edge Analyzer module can monitor only one gas family (such as hydrides or
mineral acids).
Control Systems
The Vertex Edge control system consists of a central data acquisition computer (DAq), and one
or more analyzer modules.
Following is a simplified block diagram of the communications path of the control system. The
analyzer modules are microprocessor controlled and contain non-volatile memory.
