Recalibration Belt Speed Compensation In order to achieve optimum accuracy in the rate computation, the belt speed displayed must equal that of the actual belt speed. As the speeds are likely to differ, a belt speed compensation should be performed. Run the conveyor with the belt empty. View the belt speed run mode /speed display, e.g. 0.750 m/s 1 2 Stop the conveyor and measure a length of the belt; marking the forward end (start time) and the back end (stop time). Use the belt scale as the stationary reference. Run the belt and measure the time for the belt length to pass over the scale. speed = belt length m or ft. time s min.
Refer to Maneuvering on page 18 for parameter selection and value change. with conveyor running empty PROGRAM mode - assumed speede.g. 0.75 ms % enter calculated speed e.g. 0.8 m/s Start Up jumps to P014 or P015 showing new value If the BW100 constant speed input (TB1-5/6) is jumpered, the design speed (P014) is automatically adjusted. If a speed sensor is connected, the speed constant (P015) is automatically adjusted. The display speed (used in the rate computation) now equals the actual speed. Record the new value in Appendices/Program Record. 7ML19985DJ01 Milltronics BW100 - INSTRUCTION MANUAL Page 29
