10.6.11 Time until replacement of motor bearings (2.11)
This display is only shown if display 2.10 is not shown.
This display shows when to replace the motor bearings. The
controller monitors the operating pattern of the pump and
calculates the period between bearing replacements.
The estimated time until replacement of motor bearings takes into
account if the pump has been running with reduced speed.
See section 10.7.17 Confirming relubrication/replacement of
motor bearings (3.20).
10.6.12 Temperature sensor 1 (2.12)
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 1 connected to
the MCB 114. The measuring point is selected in display 3.21.
If no sensor is connected to the CUE, "–" will appear in the
display.
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

• Open loop
• Constant pressure
• Constant differential pressure
• Proportional differential pressure
• Constant flow rate
• Constant temperature
• Constant level
• Constant other value.
If the pump is connected to a bus, the control
mode cannot be selected via the CUE. See
Note
section 13.3 GENIbus signal.
