The control panel on the pump comprises the following:
7.2 Grundfos Eye
The Grundfos Eye is on when the power supply has been
switched on. See fig. 17, pos. 1.
The Grundfos Eye is an indicator light providing information about
the actual pump status.
The indicator light will flash in different sequences and provide
information about the following:
• power on/off
• pump alarms.
The function of the Grundfos Eye is described in section
10.1 Grundfos Eye operating status.
If a fault is indicated, correct the fault and reset the pump by
switching the power supply off and on.
7.3 Light fields indicating the pump setting
The pump has nine optional performance settings which can be
selected with the push-button. See fig. 17, pos. 3.
The pump setting is indicated by eight light fields in the display.
