IV-2-7. Water supply control mode
When several pumps supply water meanwhile, because of the different time(daytime and
night), different season(winter and summer), the variation of the water flow is great. To save energy
and protect the equipment, please run pumps as many as you need and stop pumps as many as you
do not need.
Inverter will confirm the number of the running pumps according to the requirement of the
pressure close loop control. In the set range, only one pump is controlled by the inverter at the same
time.
If the timing shift interval time is set 0.05~100.00, when the related running time is stable,
inverter inverter will shift up the pumps according to stop first or open first to ensure each pump
has the chance to run and avoid the pump rusted because of long time N use.
After the pumps run to the upper and lower, arrive the adding pumps or reducing pumps time,
inverter will add or redcue the pumps according to stop first or open first to ensure each pump can
run and avoid the pump rusted because of long time N use.
IV-2-8. Soft-start pump control mode
Set the soft start pump by E12 and through the input terminals o36 ~ o46, respectively
