10.6 Menu STATUS

The displays appearing in this menu are status displays only. It is
not possible to change or set values.
The tolerance of the displayed value is stated under each display.
The tolerances are stated as a guide in % of the maximum values
of the parameters.
10.6.1 Actual setpoint (2.1)
This display shows the actual setpoint and the external setpoint.
The actual setpoint is shown in units of feedback sensor.
The external setpoint is shown in a range of 0-100 %. If the
external setpoint influence is disactivated, the value 100 % is
shown. See section 13.2 External setpoint.
10.6.2 Operating mode (2.2)
This display shows the actual operating mode (Normal, Stop, Min.
or Max.). Furthermore, it shows where this operating mode was
selected (CUE menu, Bus, External or On/off button).
10.6.3 Actual value (2.3)
This display shows the actual value controlled.
If no sensor is connected to the CUE, "–" will appear in the
display.
10.6.4 Measured value, sensor 1 (2.4)
This display shows the actual value measured by sensor 1
connected to terminal 54.
If no sensor is connected to the CUE, "–" will appear in the
display.
10.6.5 Measured value, sensor 2 (2.5)
This display is only shown if an MCB 114 sensor input module
has been installed.
This display shows the actual value measured by sensor 2
connected to an MCB 114.
If no sensor is connected to the CUE, "–" will appear in the
display.

10.6.6 Speed (2.6)
Tolerance: ± 5 %
This display shows the actual pump speed.
10.6.7 Input power and motor current (2.7)
Tolerance: ± 10 %
This display shows the actual pump input power in W or kW and
the actual motor current in Ampere [A].
10.6.8 Operating hours and power consumption (2.8)
Tolerance: ± 2 %
This display shows the number of operating hours and the power
consumption. The value of operating hours is an accumulated
value and cannot be reset. The value of power consumption is an
accumulated value calculated from the unit's birth, and it cannot
be reset.
10.6.9 Lubrication status of motor bearings (2.9)
This display shows how many times the user has given the
lubricated information and when to replace the motor bearings.
When the motor bearings have been relubricated, confirm this
action in the INSTALLATION menu. See section
10.7.17 Confirming relubrication/replacement of motor bearings
(3.20). When relubrication is confirmed, the figure in the above
display will be increased by one.
10.6.10 Time until relubrication of motor bearings (2.10)
This display is only shown if display 2.11 is not shown.
This display shows when to relubricate the motor bearings. The
controller monitors the operating pattern of the pump and
calculates the period between bearing relubrications. If the
operating pattern changes, the calculated time till relubrication
may change as well.
The estimated time until relubrication 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).
