Setting instructions

Note
Even flow through the modules in parallel operation
Make sure that there is an even flow of sample gas through the connected modules. To do
this, measure the flow rate. Set the same flow rate for each connected analyzer module.
Information on module-specific values is available in the technical specifications of the
Operating Instructions/Compact Operating Instructions: → References (Page 115).
Serial/parallel operation
Note
Parameter assignment of the gas path depending on the operating mode
Analyzer modules can be operated in series or in parallel.
● If you are only using one analyzer module or want to operate two analyzer modules in
series, set the value "Shared" in the "Gas path" parameter field.
● If you are operating two analyzer modules in parallel, however, select the setting "Separate".
You can find the corresponding setting options in the menu → [2.12].
Serial/parallel operation
If you are using two analyzer modules in a rack-mounted or wall-mounted device, the analyzer
modules can be operated in series or in parallel:
● In serial operation, the analyzer modules are connected to the sample gas line in such a
way that the sample gas flows through the analyzer modules one after the other. For this
purpose, you have to connect the sample gas outlet of the primarily supplied analyzer
module to the sample gas inlet of the second analyzer module operated in series.
● In parallel operation, the analyzer modules of the device are connected in such a way that
the analyzer modules are supplied independently with sample gas.
Pressure operation/Suction operation
The analyzer modules can also be operated in pressure operation and in suction operation:
● Pressure operation: For sample gas supply, only the overpressure of the sample gas from
the gas line or gas cylinder is used.
● Suction operation: The sample gas is sucked away by a downstream pump.
