19.2.5 Power input and power consumption
Tolerance: ± 10 %
This display shows the actual pump input power from the power
supply. The power is displayed in W or kW.
The pump power consumption can also be read from this display.
The value of power consumption is an accumulated value
calculated from the pump's birth and it cannot be reset.
19.2.6 Operating hours
Tolerance: ± 2 %
The value of operating hours is an accumulated value and cannot
be reset.
19.2.7 Lubrication status of motor bearings (only 15-30 hp)
This display shows how many times the motor bearings have
been relubricated and when to replace the motor bearings.
When the motor bearings have been relubricated, confirm this
action in the INSTALLATION menu.
See section
19.3.14 Confirming relubrication/replacement of
motor bearings (only three-phase pumps)
on page
31
.
When relubrication is confirmed, the figure in the above display
will be increased by one.
19.2.8 Time till relubrication of motor bearings
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 displayable values are these:
• in 2 years
• in 1 year
• in 6 months
• in 3 months
• in 1 month
• in 1 week
• Now!
19.2.9 Time till replacement of motor bearings
When the motor bearings have been relubricated a prescribed
number of times stored in the controller, the display in section
19.2.8 Time till relubrication of motor bearings
on page
25
will be
replaced by the display below.
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 displayable values are these:
• in 2 years
• in 1 year
• in 6 months
• in 3 months
• in 1 month
• in 1 week
• Now!

19.3.2 Controller
E-pumps have a factory default setting of gain (K
p
) and integral
time (T
i
). However, if the factory setting is not the optimum
setting, the gain and the integral time can be changed in the
display below.
• The gain (K
p
) can be set within the range from 0.1 to 20.
• The integral time (T
i
) can be set within the range from 0.1 to
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
p
)
must be set within the range from -0.1 to -20.
