Terminals 10, 11 and 12 are not used.
A liquid level switch is to be connected to terminals 18 and 20.
The pump will turn on when the contact is closed.
Relay 1 is pump running: Terminals 1 and 2
Relay 2 is Alarm: Terminals 4 and 5
Outlet pressure sensor: Terminals 12 (brown wire) and 54 (black
wire) inlet pressure sensor: Terminals 1 (brown wire) and 2 (black
wire) of the MCB114. Terminal A54 set to I prior to power
connection to CUE. See power supply to CUE and motor above.
For further information, see the separate installation and
operating instructions supplied with the Grundfos CUE frequency
converter.
