Chapter 7: Gas Analyzer Configuration

Replacing a System Module
Removing and
Reinstalling an
Existing System
Module
As a rule, when an existing system module is removed and reinstalled (e.g. after a
repair) it does not require any setup.
When the system module is reconnected to the system bus it is automatically
recognized and its configuration is automatically stored. For automatic recognition
to take place the gas analyzer must be in measurement mode.
CAUTION!
When an existing system module is replaced with another system module the
function “DELETE” should not be used to delete the old system module. This
function would irretrievably delete the parameter settings and function block
configuration of the old system module!
In order to preserve the parameter settings and function block configuration
of the old system module when replacing a system module, the function
“CHANGE” must be used.
•
The type and configuration of the new system module must match the charac-
teristics of the old system module.
•
When an existing I/O module has been replaced with an I/O module of the same
type, the new I/O module is automatically recognized by the gas analyzer and its
configuration is not necessary.
