Resetting A Fault Indication; Reading Out Warning And Alarm Codes In Grundfos Go Remote - Grundfos MAGNA1 C Series Installation And Operating Instructions Manual

9.1.1 Multipump system operating indications
When connecting Grundfos GO Remote to a multipump setup
and choosing "system view", Grundfos GO Remote will indicate
the system's operating status and not the status of the pump
itself. Therefore the indicator light in Grundfos GO Remote might
differ from the indicator light shown on the pump's operating
panel. See the table below.

9.2 Resetting a fault indication

To reset a fault indication, eliminate the fault cause, see section
9.4 Fault finding table, and reset the pump by pressing the button
on the pump. If the pump does not revert to normal duty, the fault
cause is not eliminated.
If the fault disappears by itself, the fault indication is automatically
reset.
A fault can also be reset by using Grundfos GO Remote. See
section 9.3 Reading out warning and alarm codes in Grundfos
GO Remote.
