Internal Messages
The menu [Operation / Self-Supervision / Messages] gives access to the list of internal
messages. In particular, it is recommended to check these in case of some problem
directly related to the functionality of the EMR-3MP0.
All messages that can potentially appear here are described in detail in a separate
document, the "E‑Series Troubleshooting Guide" (MN026003EN).
Device Taken out of Service ("Device Stopped")
The protection device will be taken out of service, if there is an undefined state that
cannot be escaped after three reboots.
In this state the system LED will be illuminated red or red flashing. The display will show
the message "Device Stopped" followed by a 6-digit error code, e.g. E01487.
In addition to the recorders, messages and display information that can be accessed by
the user, there may exist additional error information accessible by the Service Staff.
These offer further failure analysis and diagnosis opportunities to the Service Staff.
