METHOD AND APPARATUS FOR CONTROLLING A PUMP

摘要

A pump control apparatus includes a pump (13) coupled at an inlet to a water source (14) and at an outlet to a first dispensing valve (18) and a carbonator (15) via a check valve (16). A power source (12) is coupled to the pump (13), and a controller (11) regulates the delivery of power from the power source (12) to the pump (13). Responsive to a fill signal received from the carbonator (15), the controller (11) activates the power source (12) to deliver power to the pump (13) at a first predetermined level. Alternatively, the controller (11) activates the power source (12) to deliver power to the pump (13) at a second predetermined power level in response to a dispense signal received from the dispensing valve (18).
