System Calibration

3.1 Set-up analyzer modules

Before we can run any system calibration features we have to include the different analyzer modules(AM) into system calibration by setup needed parameters. Only after correct setting up, an AM is included into system calibration and only then it makes sense to go into the other menus.

OVERVIEW

 

SCAMGAS SCVALVE SCPURGE

SCMODULE SCCONTROL

Setting up an AM for system calibration means assigning valves from system valve pool.

The Control Module provides support of up to 16 system-valvesV1....V16. We have to

decide which valves deliver which gases for an analyzer module. Also we have to know the purge time from a valve to the AM.

For each of the following types in the parameter „Gas type“ we have to assign a valve and the appropriate purge time :

∙SAMPLE-GAS

∙ZERO-GAS

∙SPANGAS-1 (spangas for range 1)

∙SPANGAS-2 (spangas for range 2)

∙SPANGAS-3 (spangas for range 3)

∙SPANGAS-4 (spangas for range 4)

Conditions for the assignment:

·Once a valve has been assigned to be a sample gas valve for any AM it must not be used for zero or span gases !

·The zero valve of an AM can not be a span valve of the same AM.

·All gas types have to be assigned to a system-valve.
