Abstract:
1. A control system for an ice-making machine, wherein the ice-making machine comprises an evaporator and a sump, wherein fluid flows through said evaporator and into said sump, the control system comprising: a controller; at least one flow sensor to detect a flow of fluid exiting said evaporator; and a sump sensor to detect a level of fluid disposed in said sump, wherein said at least one flow sensor and said sump sensor are in electrical communication with said controller, wherein said controller controls said ice-making machine to enter a freezing cycle to freeze said fluid, or a harvest cycle to harvest said frozen fluid, based upon inputs from said at least one flow sensor and said sump sensor, and wherein said controller controls said ice-making machine to enter said freezing cycle if said at least one flow sensor detects that said flow of fluid is above a first amount, and said sump sensor detects that said level of fluid is above a second amount.
