Error description and solution
PASS
Calibration was successful. No Errors found.
Er 1
Signal read by the amplifier is too large when maximum tension
is applied. This is caused by maximum tension being too large.
Reduce maximum tension.
Er 2
Signal read by the amplifier is too small. Too little of the load cell
range is being used, thus the gain is greater than 32:1. Use more
of the load cell range or set maximum tension higher.
Er 3
Roller weight too large. Roller weight exceeds 90% of the load
cell rating. Make roller weight smaller.
Er 4
Calibration tension is greater than maximum tension. Make
maximum tension larger than calibration tension.
Er 5
Maximum tension exceeds the load cell rating. Lower wrap angle,
make roll weight smaller, get higher rated load cells, or lower
maximum tension.
