Alarms And Warnings; Operating The Product; Starting And Stopping The Product; Emergency Stop - Grundfos BACMON Installation And Operating Instructions Manual

8.2 Alarms and warnings

The product has two ways of notifying the user of an error, alarms
and warnings.
Both alarms and warnings have error codes that will be shown in
the display and reported to the water quality server.
A warning does not affect the operation of the product, it just
notifies the user that an error has occurred.
If a hardware fault is critical so that it is impossible to continue
normal operation, an alarm is triggered. This can happen if a
hardware warning keeps reoccurring or if a critical fault occurs.
The user is notified and the product stops operating and goes into
alarm state.
The product will stay in alarm state until the user manually clears
the alarm via the operating panel after correcting the fault that
caused the alarm.
In case of alarms related to the water quality, the product will
continue operating.
