20.7 Estimating Duration to Overflow
When the well level is rising (pumps on or not, the inflow may defeat the pumps) the MultiSmart can estimate
the duration to overflow and display it until the level reaches the overflow level. This calculation is dynamic
and based on the dynamic rate of level increase. This time estimation is available in the DNP and MODBUS
points list so that it can be sent to SCADA.
To be able to use this feature, the flow module must be enabled in the MultiSmart. (If not enabled, refer to
Section 28).
Navigate to:
Under the flow General Settings button, check the Flow Enabled and Overflow Enabled check boxes and
set the % Level for Overflow.
To display the Duration to Overflow in the main screen browse to:
Select the Line in which the data is to be displayed from the left column and then select Duration To
Overflow from the right column and press Save. This value now appears in the bottom section of the main
screen display.
NOTE: When a probe is selected as the level device the setpoints need to be at least 20 percent
wide so that the duration to overflow can be calculated.

Questions and answers
I have four pumps connected to my multi smart. One jockey and three that rotate with the jockey as needed. My problem is that the jockey pump always shows its running even when it isn't running. the other pumps show actuate run times and starts. only the main pump shows continuous run even when it is turned off. I was wondering if there any advice I could be given to resolve this issue.
The MultiTrode MultiSmart may show the jockey pump as continuously running even when it is turned off due to the "External Run" status. This occurs if the pump is started by an external control method, such as a manual override switch, where the contactor remains closed but no run command was sent by the controller. As a result, the system continues updating run time statistics and generating relevant faults or warnings. Checking for an external control signal or a stuck contactor may help resolve the issue.
