If the stop bolt [4] and lock nut [5] were
loosened during removal or installation,
they will need to be reset.
The gap between
the upper load cell stop bold and the load cell
should be about .005” (use a feeler gauge for
value) when the weigh bin is in place and at
rest. Once set, tighten the lock nut.
6
Screw nut [1] and lock nut [2] onto hanger
mounting screw [8] but do not yet tighten.
The purpose of this bolt and nut is to prevent
over-travel of the load cell to prevent damage to
the cell.
7
Use a feeler gauge and make the gap between the load cell stop bracket and the bot-
tom of the nut .040”.
Once the distance is set, tighten the two nuts. Alternatively, this
can be set by either hanging a weight of 10 kg on each individual load cell hanger brack-
et, or reinstalling the weigh bin and loading it with a total weight of 20 kg. Once this
weight is installed set the gap between the nut and the load cell stop bracket to zero dis-
tance then tighten the two nuts.
8
To complete the installation of the load cell, it is necessary to pre-stress the load cells.
This can be preformed in two ways. Either by hanging a weight of 10 kg on each individ-
ual load cell hanger bracket, or reinstalling the weigh bin and placing a 20 kg weight into
the bin. This weight should stay in place for 10 seconds, then be removed. Repeat this
procedure three times.
9
Complete an empty and full calibration
(see the Operation section entitled, Menus-
Hopper Setup, Calibration)
,
then operate as normal.
