10.6.13 Temperature sensor 2 (2.13)
This display is only shown if an MCB 114 sensor input module
has been installed.
This display shows the measuring point and the actual value
measured by Pt100/Pt1000 temperature sensor 2 connected to
the MCB 114. The measuring point is selected in display 3.22.
If no sensor is connected to the CUE, "–" will appear in the display.
10.6.14 Flow rate (2.14)
This display is only shown if a flowmeter has been configured.
This display shows the actual value measured by a flowmeter
connected to the digital pulse input (terminal 33) or the analog
input (terminal 54).
10.6.15 Accumulated flow (2.15)
This display is only shown if a flowmeter has been configured.
This display shows the value of the accumulated flow and the
specific energy for the transfer of the pumped liquid.
The flow measurement can be connected to the digital pulse input
(terminal 33) or the analog input (terminal 54).
10.6.16 Firmware version (2.16)
This display shows the version of the software.
10.6.17 Configuration file (2.17)
This display shows the configuration file.

10.7 Menu INSTALLATION

10.7.1 Control mode (3.1)
Select one of the following control modes:
• Open loop
• Const. pressure
• Const. diff. pressure
• Prop. diff. pressure
• Const. flow rate
• Const. temperature
• Constant level
• Const. other value.
If the pump is connected to a bus, the control
mode cannot be selected via the CUE.
Note
See section 13.3 GENIbus signal.
10.7.2 Controller (3.2)
The CUE has a factory setting of gain (K
However, if the factory setting is not the optimum setting, the gain
and the integral time can be changed in the display.
• The gain (K ) can be set within the range from 0.1 to 20.
p
• The integral time (T ) can be set within the range from 0.1 to
i
3600 s. If 3600 s is selected, the controller will function as
a P controller.
• Furthermore, it is possible to set the controller to inverse
control, meaning that if the setpoint is increased, the speed
will be reduced. In the case of inverse control, the gain (K
must be set within the range from –0.1 to –20.
