Patent ID: 7151459

Claim:
A control panel apparatus for a wastewater system comprising: a housing; at least one processor mounted within the housing, wherein the at least one processor is adapted to receive at least one condition signal representative of a condition associated with a reservoir comprising a fluid; at least one alarm output device in operative connection with the at least one processor, wherein the at least one processor is operative responsive to the at least one condition signal to cause the at least one alarm output device to output an alarm signal; and at least one contact relay mounted within the housing, wherein the at least one contact relay is operative to open and close at least one AC circuit which is operative to power run windings of at least one motor of at least one pump, wherein the at least one pump is operative to change a depth level of the fluid level in the reservoir responsive to the at least one condition signal, wherein the at least one processor is operative to cause the at least one contact relay to at least one of open and close the at least one AC circuit responsive to the at least one condition signal and responsive to at least one of current and voltage of the at least one AC circuit being within a predetermined amount of time of a cross-over point.
