17.7.15 Operating range (3.18)

How to set the operating range:

Set the min. speed within the range from a pump-dependent
min. speed to the adjusted max. speed. The factory setting 
depends on the pump family. 

Set the max. speed within the range from adjusted min. speed
to the pump-dependent maximum speed. The factory setting 
will be equal to 100 %, i.e. the speed stated on the pump 
nameplate.

The area between the min. and max. speed is the actual 
operating range of the pump.

The operating range can be changed by the user within the 
pump-dependent speed range.

For some pump families, oversynchronous operation (max. speed 
above 100 %) will be possible. This requires an oversize motor to 
deliver the shaft power required by the pump during 
oversynchronous operation.

10.7.16 Motor bearing monitoring (3.19)

The motor bearing monitoring function can be set to these values:

Active

Not active.

When the function is set to 

Active

, the CUE will give a warning 

when the motor bearings are due to be relubricated or replaced.

Description

The motor bearing monitoring function is used to give an 
indication when it is time to relubricate or replace the motor 
bearings. See display 2.10 and 2.11.

The warning indication and the estimated time take into account if 
the pump has been running with reduced speed. Furthermore, the 
bearing temperature is included in the calculation if temperature 
sensors are installed and connected to an MCB 114 sensor input 
module.

10.7.17 Confirming relubrication/replacement of motor 

bearings (3.20)

This function can be set to these values:

Relubricated

Replaced

Nothing done

.

When the motor bearings have been relubricated or replaced, 
confirm this action in the above display by pressing "OK".

Relubricated

When the warning 

Relubricate motor bearings

 has been 

confirmed, 

the counter is set to 0.

the number of relubrications is increased by 1.

When the number of relubrications has reached the permissible 
number, the warning 

Replace motor bearings

 appears in the 

display.

Note

The counter will continue counting even if the 
function is switched to Not active, but a warning 
will not be given when it is time for relubrication. 

Note

Relubricated cannot be selected for a period of 
time after confirming relubrication.
