change in configuration and force you to resolve the differences.

Use the Edit parameters screen to review and update any
method setpoints.
Methods stored in GC
Methods stored in the GC that do not match the new
configuration must be updated. Make the necessary additions or
modifications. Store this method over the old method.
When you load a method, the GC compares the method against
the current hardware it detects (inlet types, detector types, PCM,
heaters, valves, and so forth). A method which does not match is
not loaded. Default setpoints for this configuration are loaded.
Before adding new hardware or changing the installed hardware
type, verify that any methods stored in the GC have been
documented.
When trying to change the GC configuration—as by adding,
removing, or changing an Inlet module—you may encounter this
or a similar message:

automatically set to On.
