CHAPTER 4 REPAIR PROCEDURES
4.5 REPLACING THE LOAD CELL COMPONENT (Cont.)
7. Position the Load Cell and Frame in the Bottom Housing and install the four retaining screws
through the Frame into the Bottom Housing. See Figure 4-17.
4.5.1 Overload Protection Stop Adjustment
When a Load Cell has been replaced in the existing Load Cell frame, the Overload Protection Stops must
be set before calibrating or testing the scale. This will require the use of mm feeler gauges ranging from
0.6 to 1.6 mm and masses. See Table 4-2.
1. At each Overload Stop Protection location, insert the proper feeler gauge as specified in Table 4-2.
2. With the correct feeler gauge positioned in the first Overload Protection Stop, press down on the
Frame and see if there is movement of the frame. Adjust the Overload Protection Stop until there
is no movement with the feeler gauge inserted. The resulting gap should be the thickness of the
feeler gauge. Do all four stops and recheck until settings are correct.
