Removal.
Î Removal of one load cell (both load cells in the unit follow the same procedure)
Î Remove the weigh bin
Î The load cells are very sensitive and must be handled with care. Make sure
that when the load cell is being removed or installed that there is no torque
affects applied to the load cell.
Î Disconnect the wiring that extends into the control box (see wiring diagram)
Î Before removing the load cell look at the general location of all the items to see
how the items are installed before removing.
Î Remove the load cell cover plate (figure 20, item 7) by loosening the load cell
cover plate holding nuts (figure 20, item 4) and sliding the cover upward off of
the studs.
Î Unscrew the two hex nuts (figure 20, item 2 and 3) and remove the two hex
bolts (figure20, item 5) from the load cell and remove the weigh bin hanger
(figure 20, item 6).
Î Remove the two screws (figure 20, item 8) that mount the load cell to the load
cell-mounting bracket (figure 20, item 11) and remove the old load cell.
Î There is not need to remove the stop screw (figure 20, item 9) and lock nut
(figure 20, item 10) during removal of the load cell. It should remain in place so
no adjustment is needed during installation.
