Figure 3-16. Load Cell Frame Mounting Bolt Locations.

3.5.1 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 3-2.
1. At each Overload Stop Protection location, insert the proper feeler gauge as
specified in Table 3-2.
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.
