2. Product introduction
2.1 Product description
CUE is a series of external frequency converters especially
designed for pumps.
With the startup guide in CUE, the installer can quickly set central
parameters and put CUE into operation.
Connected to a sensor or an external control signal, CUE quickly
adapts the pump speed to the actual demand.
The operating panel displays any alarms or warnings.
If the pump speed exceeds the rated speed, the pump will
be overloaded.
2.2 Intended use
CUE frequency converters can be used in both new and existing
installations. Local operation is performed via the operating panel
which has a graphic display showing the menu structure. The menu
structure uses the same system as Grundfos E-pumps.
Remote operation is performed via external signals, for instance via
digital inputs or GENIbus.
2.3 Applications
The CUE series and Grundfos standard pumps are a supplement to
the Grundfos E-pumps range with an integrated frequency
converter.
A CUE solution offers the same E-pump functionality in these
cases:
•
in mains voltage or power ranges not covered by the E-pump
range
•
in applications where an integrated frequency converter is not
desirable or permissible.
