143  Start not possible 

since the loading 

quantity or the 

residual quantity is 

too small 

The defined loading quantity is too low or start is not possible 

because the residual quantity that is still to be loaded is too little. 

The quantity to be loaded in DR 21 is less than the defined

weighing range value in DR 3. Correct the values. 

A dosage in AWI totalizing loading operation cannot be started 

since the residual quantity is less than the defined minimum
