CONTROLLER FOR A MOTOR AND A METHOD OF CONTROLLING THE MOTOR
First Claim
1. A pumping apparatus for a jetted-fluid system comprising a vessel for holding a fluid, a drain, and a return, the pumping apparatus being connectable to a power source and comprising:
- a pump comprising an inlet connectable to the drain, and an outlet connectable to the return, the pump adapted to receive the fluid from the drain and jet fluid through the return;
a motor coupled to the pump to operate the pump; and
a controller supported by the motor, the controller being configured to at least control the motor, the controller including a timer function configured to receive instructions indicating time periods related to at least one mode of operation of the controller.

Abstract
A method of controlling a motor operating a pumping apparatus of a system includes determining a trip value for a parameter, floating the trip value, and monitoring the operation of the pump. Monitoring the operation of the pump includes determining a value for the parameter, comparing the value to the trip value, and determining whether the comparison indicates a condition of the pump. The method of controlling the motor also includes controlling the motor to operate the pump based on the condition of the pump.

7. A method of controlling a motor operating a pumping apparatus of a jetted fluid system comprising a first vessel for holding a first fluid, a first drain supported by the first vessel, a first return supported by the first vessel, a second vessel for holding a second fluid, a second drain supported by the second vessel, and a second return supported by the second vessel, the pumping apparatus comprising
a pump having an inlet connectable to the first drain and the second drain, and an outlet connectable to the first return and the second return, the pump adapted to receive the first fluid and the second fluid from the first drain and the second drain, respectively, and jet fluid through the first return and the second return, and the motor coupled to the pump to operate the pump, the method comprising: -
operating the system in one of at least two states, the first state includes receiving the first fluid from the first drain, and the second state includes receiving the second fluid from the second drain; determining a first trip value; determining a second trip value; determining a value related to a parameter for the motor; comparing the value to the first trip value when in the first state; comparing the value to the second trip value when in the second state; determining whether at least one of the comparisons indicate a condition of the pump; and controlling the motor to operate the pump based on the condition of the pump. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A pumping apparatus for a jetted-fluid system comprising a first vessel for holding a first fluid, a first drain supported by the first vessel, a first return supported by the first vessel, a second vessel for holding a second fluid, a second drain supported by the second vessel, and a second return supported by the second vessel, the pumping apparatus being connectable to a power source and comprising:
-
a pump having an inlet connectable to the first drain and the second drain, and an outlet connectable to the first return and the second return, the pump adapted to receive the first fluid and the second fluid from the first drain and the second drain, respectively, and jet fluid through the first return and the second return; a motor coupled to the pump to operate the pump; a sensor configured to generate a signal having a relation to a parameter of the motor; a switch coupled to the motor and configured to control a characteristic of the motor; and a microcontroller coupled to the sensor and the switch, the microcontroller configured to operate the motor in one of at least two states, the first state including receiving the first fluid from the first drain, and the second state including receiving the second fluid from the second drain, generate a value based on the signal, compare the value to a first trip value when operating in the first state, and compare the value to a second trip value when operating in the second state. - View Dependent Claims (16, 17, 18, 19, 20, 21)
