relubrication/replacement of motor bearings (only three-phase
pumps)
. When relubrication is confirmed, the figure in the above
display will be increased by one.
9.2.8 Time till relubrication of motor bearings (only 11-22 kW)
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!
