1
Position the new load cell
[1] (both load cells in the
unit follow the same proce-
dure) so that the notch on
the load cell is facing
downward.
Place a small
amount of removable
strength Loc-tite
™
on the
two screws [8] and re-attach
the new load cell to the
mounting bracket [11].
Make sure that the load cell
is parallel with the chassis
wall and the load cell mount-
ing bracket. Tighten to
10Nm.
2
Re-attach the weigh bin hanger [6]
and install the two screws [5].
The
longer of the two screws should be clos-
est to the chassis wall. Only snug the
screw at this time - further adjustment
needs to be made before fully tightening
them.
3
Re-install the weigh bin into the
blender chassis and position hanger
[6] so weigh bin can be removed and installed easily.
The weigh bin should be
installed so it is centered in the chassis and does not contact the weigh bin when the
cylinder is at rest. Once satisfied with placement, tighten the two screws [5] to 10 Nm.
Make sure that nothing is twisted after installation and tightening.
4
Re-route and install the wiring from the load cell to the appropriate location in the
control box.
W A R N I N G : E l e c t r i c S h o c k
High voltages can cause life-threatening currents in the body and injury from elec-
tric shock. Allow only trained and qualified electrical technicians to work on the
electrical system. Before any electrical work, disconnect the unit from the power
supply and lock to prevent unauthorized persons switching it on.
Do NOT use excessive force. Forces that are exerted on the load cell from outside
when attaching and removing the weigh bin load cell may damage the very sensi-
tive load cell.
