6.3 Balancing
For applications where the conveyor loading does not repeat in locations across the width of the
belt, such as side-to-side loading, electronic balancing of the two load cells is recommended.
Balancing is completed during the initial start-up, but should be repeated if either load cell is
reinstalled or replaced. Refer to the associated integrator manual to complete the balancing
procedure.
When balancing load cells, apply a test weight to the extreme sides (side A or B), as required.
①
Test weight bracket
②
Test weight (calibration flat bar)
Note
Position the test weight flush with the sides of the brackets when balancing load cells.
Reverse position of bar to balance other load cell.
6.4 Final calibration
Program the belt scale integrator as suggested in its operating instructions and with parameters
suitable for the application. With programming complete, the system is ready for calibration.
A zero calibration can be performed after sufficient running of the conveyor allows the belt to
limber up and take its natural formation. A zero calibration is performed in accordance to the belt
scale integrator operating instructions with the conveyor running empty.
