Inaccurate Weight Readings
Inaccurate weight readings, large fluctuations in readings, weight not changing, or error messages can be caused by
obstructions and binding, incorrect user programmed settings, a problem within the Smart Summing Box, or a
problem with a load cell.
1. Check for binding and/or obstructions
Slow weight shifts or not returning to zero are frequently symptoms of a binding or obstruction problem.
a.
Check for binding of brackets and/or bin legs. Ensure there is approximately ¼” clearance between the
leg and the bracket.
b. Check for loose bolts. Inspect bolts connecting bracket to bin leg and C-Channel to load cell.
c. Check for material under the bin leg. Small rocks between the bin leg and the concrete can cause
inaccurate readings.
2. Check the Indicator settings
Incorrect weight readings when the system is otherwise functioning normally can be due to incorrect settings.
a. Confirm Rated Output
– should match the average output recorded on each load cell (3.000 for HerdStar-
supplied load cells)
b. Confirm Capacity
– equals the total capacity of all load cells summed together.
c. Confirm Zero
– bin may have been zeroed when not empty.
3. Inspect the Smart Summing Box
Small fluctuations in weight can be caused by a problem with the Smart Summing Box.
a. Inspect for moisture and/or foreign material.
b. Inspect for loose wires and connections.
4. Inspect Load Cells
Wild fluctuating weights, a weight that does not change, a negative weight reading, or
on the Indicator
display are common indications of a load cell problem.
a. Inspect load cell connections within the Smart Summing Box. A wire that is not seated properly within the
load cell connector can cause inaccurate readings.
b. Check for cut or pinched load cell wires.
c. See
Load Cell Troubleshooting Procedures
Error Messages
There are a few types of errors that can be encountered during operation of the BinTrac system. The following should
give you some insight into the cause of the error should one occur. Errors displayed are specific to the selected bin.
If this is displayed on the screen, the BinTrac Indicator is unable to display the current value, or the value is outside of
the displayable range.
1. Verify programmed settings are correct
a. Verify Zero calibration is valid and in range
b. Verify load cell capacity (L.C.Cap) has been correctly programmed
2. Open Smart Summing Box and inspect load cell connections
a. Verify connector is properly aligned with its associated header
b. Verify wires are properly seated in each connector
3. Check for faulty load cell (See Load Cell Troubleshooting Procedures )
