JAM DETECTION SYSTEM FOR A WAREWASHER

摘要

A warewasher jam detection system includes a conveyor drive arrangement having a drive motor assembly including a drive motor and an output shaft, a nd a slip clutch including an input side moved via the output shaft and an output side operatively connected for driving a conveyor. At least one sensor is provided for producing an output indicative of movement/non-movement of the output side of the clutch. Preferably the sensor is a non-contact type sensor such as a magnetic sensor, optical senso r or proximity sensor. A controller may be provided for receiving the sensor output signals and identifying a jam condition based upon the same, such that the controller ca n responsively stop the drive motor.
