7.5 Warnings and alarms
A supervision function monitors the system and detects failures.
The failures are categorised into warnings and alarms. See also
section:
7.4.3 Grundfos

Type
Indication
The Grundfos Eye in the
Warning
display turns yellow
The Grundfos Eye in the
Alarm

The supervision function is always active when the system is in
automatic mode. When the system is in semi-automatic mode,
the supervision function is only active while manual control is
disabled. In manual control, the supervision only covers the
alarms 105, 106, 107, 108, because they are the most important
alarms for the protection of the UF membrane.
