ABSTRACT:
A bulk material handling system includes a bulk material handling apparatus to convey bulk material and a bulk material handling accessory to aid the bulk material handling apparatus in conveying the bulk material. The bulk material handling accessory includes a controller having one or more sensors. The controller generates a control signal to adjust operation of the bulk material handling accessory based upon at least one status signal of the one or more sensors. The controller also generates the control signal in accordance with a status signal to control signal response pattern defined by system parameter values. The system parameters include a minimum value to define a minimum level of the control signal associated with fail-safe operation and a maximum value to define a maximum level of the control signal associated with stable operation the bulk material handling accessory.
