Check the base frame for damage or incorrect assembly
Search for damaged isolation of the cabel and repair it. ( If
appropriated use multimeter.)
Replace the electronics
The electronics have detected an error.

module number
n No: error number
Check connection cables, check sensor and replace as required (if
parts a replaced, a corner override is necessary)
If several load cell are used, check the allocation (colour codes)
Sensor defective, replace it possibly (a corner override is
necessary)
Load the scale at work with >50g/s
while the start process beware the scale for agitation
Recalibrate the scale
Replace the electronics
Check the plug-in connections; check the cables for interruption and
