4-7-2 Weigh Hopper Installation
Remove the weigh hopper from the shipping box and install it in the
blender on the load cell brackets. Connect the airline and close the
mixer door, securing the latch.
4-7-3 Load Cell Adjustment
The mechanical setup of the SGB blending system involves the
adjustment of the weigh hopper load cells (Please refer to the figure on
the next page). This figure illustrates the proper adjustment of the load
cell mechanical stop bolt. The setting for the positive stop is necessary
to prevent the load cell from being “over-ranged” by excessive loading
on the weigh hopper. The setting for the load cell stop is forty
thousandths of an inch maximum (.040”). A feeler thickness gauge, with
the weigh hopper empty, should be used to set this.
If a feeler gauge is not available, the weigh hopper should be filled with
the material that is to be blended, and the stop adjusted so there is just a
very small gap (a couple of sheets of notebook paper) between the load
cell, and the blender base stop. This will allow the load cell to operate
without mechanical restrictions and provide an overload safety. To adjust
the stop, adjust the screw located on the bottom of the load cell. Adjust
the screw up to increase the gap and down to decrease the gap.
Important! THE WEIGH HOPPER ASSEMBLY MUST HANG FREELY AND BE
FREE FROM FRICTION, WITH NO MECHANICAL OBSTRUCTIONS
OTHER THAN THE LOAD CELL ITSELF.
