  • Patent number: 4686439
    Abstract: An electronic control system for a multiple speed fluid pump and motor. A parameter of the motor, the pump, or the fluid which is expelled from the pump is measured by a sensor. When a predetermined value of the parameter is reached, the sensor provides a trip signal to a timer circuit. The timer circuit provides a drive signal to a switch while the trip signal is present and for a specified period of time after the trip signal is removed. The switch, while it is receiving the drive signal, connects the motor driving the pump into a high speed configuration. After the specified period of time, the switch will cause the motor to change to low speed operation.
