6.40 List of displays

Pending errors are assigned priorities. From priority 6, alarm messages are delivered,
which are used by remote supervision (OCI). In addition, the alarm relay is set.

6.40.1 Error code list

The LMS14... supports a 16-bit error code. Older types of operator units might display
8-bit error codes. If different from the 16-bit error code, the corresponding 8-bit error
code is indicated in parentheses.
