50 Program features
• The following triggers are used for parameter
:
• Manually (With DI4, DI5 or DI6 defined by parameter
)
• Through fieldbus or from control panel, with parameter
. To start a cleaning cycle, set the parameter to a value of 1 or
from the fieldbus.
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
, supervision is not
executed. If you change the parameter
, 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.
