Trip / Warning History
The E300 Electronic Overload Relay provides a trip and warning history in
which the last five trips and last five warnings are recorded into nonvolatile
storage. A mask is available to limit which trip and warning events are logged to
the history's memory.
Trip History
When the E300 Electronic Overload Relay issue a trip, the reason for the trip is
recorded into the Trip History. Table 476
lists the codes that are available for the
trip history records.
