190 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
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 automati-
cally 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 func-
tion block configuration of the old system module.
In order to retain the parameter settings and function block configuration
of the old system module when replacing a system module, the function
"Change" must be used.
NOTES
The type and configuration of the new system module must match the con-
figuration 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 ana-
lyzer and its configuration is not necessary.
Replacing an existing system module (analyzer module or I/O device) with
another system module
1 Select the Set Up System Modules menu item.
The list of the system modules existing in the system is displayed.
2 Select the system module (analyzer module or I/O device) to be replaced
and reconfigured.
In the list this system module will be shown with an Unknown or Error
status.
3 Press the CHANGE softkey.
Do not press the DELETE softkey! This would irretrievably remove the
system module’s parameter settings and function block configuration!
4 Enter the 14-digit serial number for the new system module.
5 In the list the new system module will now be shown with the Replaced
status.
6 Save the configuration change by pressing ENTER or discard it by
pressing Back.
