5.5 Configuration Error Messages
If HCD-E1 detects a configuration mismatch, it displays an appropriate
configuration error message. These messages appear both on the LCD and
on the supervision terminal. Some of the messages are not available on the
LCD. There is also one unavailable on the supervision terminal.
On the control terminal, configuration error messages have the format
ERROR, followed by a two-digit code and a short description of the error
message after the error code. The LCD displays CONFIG ERROR followed
by the error two-digit code, without description. Table 5-5 lists the
configuration error messages in order of their codes and explains each of
them. Messages not available on the LCD are marked with an asterisk (*).
