The conveyor is rated at 100 pounds per linear foot when used on a level surface. The capacity will decrease when the conveyor is used on an incline. Do not allow boxes to accumulate on the conveyor because it will cause premature failure of the belts. Zero Pressure Accumulation is available for that type of application. B/FP 1.5 B/FP 1.9

o On center-drive conveyors, there will be a takeup pulley on each end. In this case, start with either end of the conveyor. • Take the other end of the belt and route it through the entire conveyor, taking care to follow the path laid out in the drawing. • This should result in the two belt ends meeting on top of the conveyor (see figure 4).

For example, an encoder attached to a conveyor belt can provide information about the position and speed of the belt, allowing the PLC to control the movement of the conveyor system. Overall, input devices play a crucial role in PLC circuit diagrams as they enable the PLC to receive and process signals from the field.
