摘要： 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.

摘要翻译： 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故障之前预定数量的最先前冷冻循环的平均冷冻时间。 在由于水位探头故障而处于安全模式的情况下，水阀准时基于在故障之前预定数量的最先前冻结循环的平均水阀。 如果在预定时间之后故障未固化，则控制器使制冰机进入待机模式或禁止制冰机制冰。
