5.2.1 Operating mode
Possible operating modes:
• Max.
Pump operation has been set to maximum speed,
e.g. 10,700 min
-1
.
• Normal.
Normal operating mode, i.e. pump operation is
based on the pressure setting made in display
5.1.1 Pressure setting.
• Min.
Pump operation has been set to minimum speed,
3,000 min
-1
.
• Stop.
The pump has stopped.
The operating mode was selected from one of the
following:
• CU 301 (on/off button on the CU 301).
• R100.
• Sensor (signals received via the sensor input).
5.2.2 Actual pressure
The actual system pressure measured by the pres-
sure sensor.
Tolerance: ±1%.
5.2.3 Speed
The actual speed stated in min
-1
(rpm).
Tolerance: ±1%.
5.2.4 Temperature
The actual temperature of the motor electronics
stated in “°C” or “F”.
Tolerance: ±5%.
Relation to other displays:
To select “F”, choose the language “US English”.
5.2.5 Power input and power consumption
Power input:
The actual motor power from the electricity supply.
The power input is displayed in W (watt).
Note: This value is used for the calculation of mini-
mum power limit (dry-running stop).
Power consumption:
The accumulated motor power consumption in kWh.
The value of power consumption is accumulated
from the pump’s birth and it cannot be reset.
The value
• is stored in the motor electronics, and it is kept
even if the CU 301 is replaced.
• is updated in the software every 2 minutes of con-
tinuous operation. The displayed value is updated
every two hours.
Tolerance: ±5%.
