Float Switch Conguration:
Pump-Up Mode
In a pump-up mode, the R2 relay will initiate by switching the pump when the uid level in the tank falls below the lower
tank level switch point. The R2 relay will remain energized (latched) and the pump will continue to operate until uid lls
the tank up to the high level switch point. When the uid reaches the high level switch point, the control relay will deenergize and shut off the pump. The R2 relay will remain de-energized until the uid falls below the tank’s low level switch
point.
Pump-Down Mode
In a pump-down mode, the R2 relay will initiate by switching on the pump when the uid level in the tank reaches the upper
tank level switch point. The R2 relay will remain energized (latched) and the pump will continue to operate until uid in
the tank empties down to the low level switch point. When the uid falls below the low level switch point the R2 relay will
de-energize and shut off the pump. The R2 relay will remain de-energized until the uid reaches the tank’s high level switch
point.
