Cleaning count monitoring
The cleaning count monitoring function calculates the number of cleaning cycles
inside a user-defined monitoring window. Too frequent cleaning attempts may
indicate a pump problem (such as blockage) that the pump cleaning function cannot
solve alone but it requires manual inspection and cleaning. The following figures
describes the operation of cleaning count monitoring.
For example, set the cleaning count time to one hour. The pump cleaning function
trips on a fault if it detects too frequent cleaning cycles. The drive completes three
pump cleaning cycles. The drive continuous its operation as long as the time interval
between three cleanings are over the user defined value (one hour).
The third pump cleaning cycle starts within the preset count time (one hour) and the
pump cleaning function trips on a fault and the pump is stopped without performing
the third cleaning cycle. After reseting fault, the drive starts with the third pump
cleaning cycle.
If the parameter 83.35 Cleaning count fault is set to No action , supervision is not
executed. If you change the parameter 83.35 Cleaning count fault to Warning or
Fault , the pump cleaning count starts from zero.
When the pump cleaning function is active and maximum number of cycles per time
unit is reached, the drive displays a warning which appears in the event log.
