10.3.7 Max. motor current (6/16)
Set the maximum motor current according to the motor
nameplate:
• 0-999 A.
The setting range depends on the CUE type, and the factory
setting corresponds to a typical motor current at the motor power
selected.
10.3.8 Speed (7/16)
Set the rated speed according to the pump nameplate:
• 0-9999 rpm.
The factory setting depends on previous selections. Based on the
set rated speed, the CUE will automatically set the motor
frequency to 50 or 60 Hz.
10.3.9 Frequency (7A/16)
This display appears only if manual entering of the frequency is
required.
Set the frequency according to the motor nameplate:
• 40-200 Hz.
The factory setting depends on previous selections.
10.3.10 Control mode (8/16)
Select the desired control mode. See section 10.7.1.
• Open loop
• Const. pressure
• Const. diff. pressure
• Prop. diff. pressure
• Const. flow rate
• Const. temperature
• Constant level
• Const. other value.
The possible settings and the factory setting depend on the pump
family.

The CUE will give an alarm if the control mode selected requires
a sensor and no sensor has been installed. To continue the
setting without a sensor, select "Open loop", and proceed. When
a sensor has been connected, set the sensor and control mode in
menu INSTALLATION.
10.3.11 Rated flow rate (8A/16)
This display appears only if the control mode selected is
proportional differential pressure.
Set the rated flow rate according to the pump nameplate:
3
• 1-28840 gpm (1-6550 m /h).
10.3.12 Rated head (8B/16)
This display only appears if the control mode selected is
proportional differential pressure.
Set the rated head according to the pump nameplate:
• 1-3277 ft (1-950 m).
10.3.13 Sensor connected to terminal 54 (9/16)
Set the measuring range of the connected sensor with a signal
range of 4-20 mA. The measuring range depends on the control
mode selected:
