Abstract: An improved two feeder tray bulk weighment control system of the vernier operating type is disclosed. During an initial portion of the operating cycle of the device and while the weighment from the previous cycle is being dumped, a first feeder tray is driven to deliver a preliminary bulk target of 80-98% of the desired final weighment into a second feeder tray. During the conveying portion of the operating cycle both trays are driven at a rate inversely proportional to the difference between the actual weighment and a target weighment signal in an underdamped manner. As the final weighment is approached, improved circuitry prevents scale overshoot due to the underdamped rate controllers from causing premature dumping. A servo loop is also provided to cause the feed controller in operation during the dumping portion of the operating cycle to deliver the 80-98% of desired final weighment based on its actual delivery on the previous cycle of operation.
