Abstract: A method for making clear ice comprising: filling a water sump to a predetermined level; contacting a refrigerant to an evaporator; circulating water from the sump over the evaporator to form ice on the evaporator; monitoring the water level in the sump; and monitoring the conductivity of the water in the sump to determine if the conductivity of the water is equal to or greater than a predetermined conductivity valve, (i) if the conductivity is not equal to or greater than the predetermined conductivity valve and if the water level reaches a predetermined lower water level, then complete the ice making cycle and initiate the harvest cycle; or (ii) if the conductivity is equal to or greater than the predetermined conductivity valve and if the water level has not reached a predetermined lower water level, then add additional water to the water sump.

Abstract: A controller continues to operate an ice making machine in a safe mode when a failure of a component is detected. While in the safe mode due to failure of an ice thickness probe, the freeze cycle freeze time is based on an average freeze time of a predetermined number of the most previous freeze cycles prior to the failure. While in the safe mode due to failure of a water level probe, the water valve on time is based on an average water valve on time of a predetermined number of the most previous freeze cycles prior to the failure. If the failure is uncured after a predetermined time, the controller causes the ice making machine to enter a standby mode or disables the ice making machine from making ice.

Abstract: A method of making ice in an ice making machine comprising a step producing ice within an ice making mold. Heating the ice making mold to release the ice while in a harvest mode by separating vaporous and liquid refrigerant within a receiver and feeding vapor from the receiver to the evaporator, wherein the ice-forming mold, evaporator and receiver are disposed in an ice machine unit. A final step of determining if the ice making machine is on comprising a ice bin switch measuring amount of ice in the ice bin, a pressure switch determining the pressure within the refrigeration system and by setting a time delay if the switches were not turned on to start another ice making round.

Abstract translation: 当检测到部件的故障时，控制器继续以安全模式操作制冰机。 在由于冰厚探测器的故障而处于安全模式的同时，冷冻循环冻结时间是基于在故障之前预先确定的先前冷冻循环的预定数量的平均冷冻时间。 在由于水位探针失效而处于安全模式的同时，水阀开启时间是基于在故障之前预定数量的最先前冷冻循环的平均水阀。 如果故障在预定时间后未固化，则控制器使制冰机进入待机模式或禁止制冰机制冰。
