Time until relubrication of motor bearings<br />
(only 15-30 Hp)<br />
E-<strong>pumps</strong><br />
Tolerance: ± 5 %<br />
The actual pump speed will appear in this display.<br />
Power input and power consumption<br />
Tolerance: ± 10 %<br />
This display shows the actual pump input power from<br />
the power supply. The power is displayed in W or kW.<br />
The pump power consumption can also be read from<br />
this display. The value of power consumption is an<br />
accumulated value calculated from the pump’s birth<br />
and it cannot be reset.<br />
Operating hours<br />
This display shows when to relubricate the motor bearings.<br />
The controller monitors the operating pattern of<br />
the pump and calculates the period between bearing<br />
relubrications. If the operating pattern changes, the<br />
calculated time until relubrication may change as well.<br />
Displayable values:<br />

Time until replacement of motor bearings<br />
(only three-phase <strong>pumps</strong>)<br />
When the motor bearings have been relubricated a<br />
prescribed number of times stored in the controller, the<br />
display in the previous section will be replaced by the<br />
display below.<br />
Tolerance: ± 2 %<br />
The value of operating hours is an accumulated value<br />
and cannot be reset.<br />
Lubrication status of motor bearings<br />
(only 15-30 Hp)<br />
This display shows how many times the motor<br />
bearings have been relubricated and when to replace<br />
the motor bearings.<br />
When the motor bearings have been relubricated,<br />
confirm this action in the INSTALLATION menu.<br />
See Confirming relubrication/replacement of motor<br />
bearings (only three-phase <strong>pumps</strong>), page 37. When<br />
relubrication is confirmed, the figure in the above<br />
display will be increased by one.<br />
