CUE is a complete range of external frequency converters designed for speed control of a wide range of Grundfos pumps. CUE has a built-in PI controller and offers the same functionality and user-interface as Grundfos E-pumps. CUE solutions can thus be seen as an extension to the E-pump range. By choosing a CUE-solution, you will get the following benefits:

  • Grundfos E-pump functionality and user-interface
  • application- and pump-family-related functions
  • increased comfort compared to fixed-speed pumps
  • very easy installation and commissioning compared to standard frequency converters
  • speed control of pumps up to 250 kW
  • speed control of pumps installed in potentially explosive environments.

CUE offers the following inputs and output:

  • RS-485 GENIbus
  • an analog 0-10 V input for external setpoint
  • an analog 0/4-20 mA input for sensor
  • four digital inputs for various functions, for instance external start/stop
  • two signal relays (C/NO/NC).

Accessories:
Input/output add-on board Provides additional input:

  • one 0/4-20 mA analog input for an additional sensor
  • one 0-20 mA analog output
  • two inputs for Pt100/Pt1000 temperature sensors, for instance for bearing monitoring.

Motor filters:
For reduction of dU/dt and peak voltages to the motor windings and for reduction of the acoustic noise generated in the motor, a number of motor filters are offered:

  • dU/dt filters , 11-250 kW
  • Sine wave filters, 0.55-250 kW.
