7.6.1 Grundfos Eye
Grundfos Eye is on when you switch on the power supply. See
fig. 25, pos. 1.
Grundfos Eye is an indicator light providing information about the
actual pump status.
The indicator light flashes in different sequences and provides
information about the following:
• power on and off
• pump running or stopped
• pump alarms and warnings
• twin-head connection.
The function of Grundfos Eye is described in section
8.1 Grundfos Eye operating status.
Faults preventing the pump from operating properly, for example
a blocked rotor, are indicated by Grundfos Eye. See section
8.1 Grundfos Eye operating status.
If a fault is indicated, correct the fault and reset the pump by
switching the power supply off and on.
If the pump impeller is rotated, for example when filling the pump
with water, sufficient energy may be generated to light up the
control panel even if the power supply has been switched off.
7.6.2 Light fields indicating the pump setting
The pump has nine performance settings which you can select
with the push-button. See fig. 25, pos. 3.
The pump setting is indicated by eight light fields in the display.
See fig. 25, pos. 2.
