Priority Of Settings - Grundfos MAGNA 2000-Serie Montage- Und Betriebsanleitung

8.8 Priority of settings

The external forced-control signals will influence the
settings available on the pump control panel and with
the R100. However, the pump can always be set to
max. curve duty or to stop on the pump control panel
or with the R100.
If two or more functions are activated at the same
time, the pump will operate according to the setting
with the highest priority.
The priority of the settings is as shown in the table.
Example: If the pump has been forced to stop via an
external signal, the pump control panel or the R100
can only set the pump to max. curve.

Not active when the pump is controlled

Only active when the pump is
controlled via bus.
As illustrated in the table, the pump does not react to
external signals (max. curve and min. curve) when
the pump is controlled via bus.
If the pump is to react to external signals (max. curve
and min. curve), the system must be configured for
that function.
