6.23 Configuration
Note!
During the reconfiguration of the LMS14..., following might occur:
 Errors that have already been identified continue to be present.
Such errors can be canceled via power OFF or by making a reset, depending on
the kind of response to the error.
Example:
A water pressure error is pending and, in this error state, the error is rectified
through parameterization
 Errors are identified and the LMS14... goes to lockout, depending on the type of
error.
Example:
A water pressure sensor is configured with Lockout as a response to the error,
but no sensor is connected, or the selection was not wanted.
In that case, the selected sensor is to be connected or the configuration must be
matched to the connected type of sensor.
Then, a reset must be made or power OFF is required.

The plant diagrams shown in chapter Applications can be preselected by entering the
diagram number. The plant diagram obtained is the result of preselection and
connected sensors.
Note!
The sensors shown on the desired plant diagram must be connected, thus ensuring
that automatic sensor identification does not detect some other plant diagram.
By making the preselection, the following parameter values are set:
