PRODUCT DISPENSING DIAGNOSTIC SYSTEM
First Claim
1. A diagnostic system for a mobile product dispensing machine comprising:
- a plurality of nozzles;
a hydraulic pump;
a circuit coupled to the plurality of nozzles, the circuit comprising tubular members, a pump, a screen, and a plurality of first components coupled to the tubular members, the plurality of first components comprising;
a pump motor;
a pump pressure transducer;
a flowmeter; and
a nozzle pressure transducer; and
an electronic control unit coupled to the circuit, the electronic control unit configured to receive inputs associated with a motor of the hydraulic pump and each of the plurality of first components and based on a combination of all of the inputs, determine whether one or a combination of the pump, the pump motor, the hydraulic pump, the hydraulic pump motor, the screen, the flowmeter, the nozzle pressure transducer, or at least a portion of the tubular members is causing values associated with the inputs to have a threshold difference from respective predetermined values, and provide feedback of the determination.

Abstract
A diagnostic system for a product-dispensing machine includes a plurality of nozzles, a hydraulic pump and a circuit coupled to the nozzles. The circuit includes tubular members, a pump, a screen, and a plurality of first components coupled to the tubular members. The plurality of first components includes a pump motor, a pump pressure transducer, a flowmeter, and a nozzle pressure transducer. The system includes an electronic control unit coupled to the circuit configured to receive inputs associated with a motor of the hydraulic pump and each of the first components and based on a combination of the inputs, determine whether one or a combination of the pump, the pump motor, the hydraulic pump, the hydraulic pump motor, the screen, the flowmeter, the nozzle pressure transducer, or at least a portion of the tubular members is causing values associated with the inputs to have a threshold difference from predetermined values.
