Re-route and install the wiring from the load cell to the appropriate location in
the control box.
Î The load cell upward motion stop bolt (figure 22, item 4) and lock nut (figure
22, item 5) most likely were not loosened during removal of the load cell and
should not need reset. If they were loosened the gap between the upper load
cell stop bolt (figure 22, item 4) and the new load cell (figure 22, item 7) should
be set at approx. .005” (use a feeler gauge for value) when the weigh bin is in
place and at rest. Once set tighten the lock nut (figure 22, item 5) to hold the
bolt (figure 22, item 4) in place.
Î Screw nut (figure 22, item 1) and lock nut (figure 22, item 2) onto hanger
mounting screw (figure 22, item 8) but do not tighten yet. The purpose of this
bolt and nut is to prevent over travel of the load cell to prevent damage to the
cell.
Î The gap between the load cell stop bracket (figure 22, item 9) and the bottom
of the nut (figure 22, item 1) should be about .020” (use feeler gauge). Once
this distance is set tighten the two nuts (figure 22, item 1 and 2). Alternatively
this can be set by either hanging a weight of 10 kg on each individual load cell
hanger bracket (figure 22, item 6) or re-installing the weigh bin and loading it
with a total weight of 20 kg. Once this weight is installed set the gap between
the nut (figure 22, item 1) and load cell stop bracket (figure 22, item 9) to zero
distance then tighten the two nuts (figure 22, item 1 and 2).
