Siemens Maxum II Manual

Manual Operations
Manually controlled functions can be initiated through the color touchscreen. A manually-
controlled event can occur asynchronously with any event and control some of the analyzer
operations. Controlled items include:
● Activation of solenoid valves
● Balancing detectors
● Changing a pressure or temperature set
point
● Initiating a calculation
● Report logging event
● Change the cycle time of an event
● Initiate a calibration
3.3 Analyzer Operation
This section provides an overview of the operation of the Maxum II analyzer. The examples
show a Maxum II Airless/Airbath model in order to include many optional features. Most
analyzers will have only some of these features; for example, the Modular Oven model has
no detector compartment.
The operational block diagram shows how a sample is processed within the analyzer. The
SNE functions are performed in software in new systems; older systems still have hardware
versions.
