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.
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.
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.
