Abstract
A grain dryer for providing a controlled drying process through a housing. The housing has a path for grain to be dried such that the grain is dried as the grain moves along the path. The grain dryer also has a fan and heater assembly for supplying heated air to the path for drying grain in the path. The grain dryer can control the flow of grain along said path and has sensors disposed in predetermined positions so as to detect different fault conditions. The sensors generating corresponding fault signals in response to the detection of fault conditions. The grain dryer also has a controller operatively connected to the sensors, the controller is responsive to fault signals to initiate a predetermined shutdown procedure upon receipt of any one of the fault signals. A memory is operatively connected to the controller for electronically recording and identifying information concerning shutdown procedures initiated by the controller. The grain dryer controller controls the start-up of in a predetermined manner. The grain dryer includes a memory to store identifying information in memory for a predetermined number of shutdowns initiated by the controller.
