The Belt Flip is an assembly which detects over tension on a low tension spiral belt and typically consists of the following parts, belt flip, sensor and belt flip bracket:



The Belt Flip assembly is mounted to a spiral leg under the outside edge of the spiral belt. The belt rides along the top of the belt flip (UHMW). When belt tension is good the belt weight keeps the belt flip engaged with the belt flip sensor. When belt tension becomes too great, the outside edge of the belt which rests on the belt flip will lift up disengaging the belt flip from the belt flip sensor and sending a fault signal to the HMI screen, shutting the system off. Prior to a reset of the fault, inspect system for what caused the system fault.
