Material Tests - Siemens Milltronics BW100 Instruction Manual

Material Tests

Perform material tests to verify the accuracy of the of the span calibration. If the material
tests indicate a repeatable deviation exists, a manual span adjust (P019) is then
performed. This procedure automatically alters the span calibration and adjusts the test
load (P017) value, yielding more accurate span recalibrations.
Note:
Test weights are NOT used during material tests.
1. Run the belt empty.
2. Perform a zero calibration.
3. Put the BW100 into RUN mode
4. Record the BW100 total as the start value
5. Run material at a minimum of 50% of design rate over the belt scale for a minimum
of 5 minutes.
6. Stop the material feed and run the conveyor empty.
7. Record the BW100 total as the stop value
8. Subtract the start value from the stop value to determine the BW100 total
9. Weigh the material sample if not already known.
BW100 total = _ _ _ _ _ _
