SECTION 3
Pr.9.6 RunOnIntervl Pump Run-on Interval (D = 0.00)
When submersible pumps are used, it may be necessary to pump down occasionally to
clear the sludge from the bottom of the well. This feature is controlled by Pr.9.6 and
Pr.9.7. Once in every interval defined by Pr.9.6, the pump will run-on for the time
period defined by Pr.9.7.
Enter the time interval in hours between each run-on cycle.
Pr.9.7
Pump Run-on Time (D = 0)
Enter the pump running time in seconds. Maximum 120 seconds.
Only one run-on cycle occurs per interval as set by Pr.9.6.
NOTE: a. Caution is required when choosing a value for pump run-on time,
as extended pump run-on can lead to cavitation, causing air locks or
pump damage.
b. As overflow can occur, do not use pump run-on for pump up
operation, set Pr.9.6 and Pr.9.7 to zero.
c. Care should be taken if pump sequence and pump run-on are defined
together, as pump run-on will be assigned to the last pump to turn
off, which could be any of those in the sequence.
