6.14.3 No test tolerance of weight
Once the dosage is ended, the instrument proceeds directly to the following formula or in WAIT START
condition.
For details depending on the activity type see section “Dosage procedure”.
6.15 Percentage correction of weight in flight
Premise: tolerance test must be enabled.
If the FLIGHT PERCENTAGE CORRECTION (BATCH1 FUNCTION >> Flight correction percentage step, )
has been enabled, the instrument, at the end of each dosage cycle within tolerance, calculates the
difference between the programmed flight weight value and the one actually dosed in the following dosage
cycle; the new flight weight to be taken into consideration will be the previous one plus or minus a fixed
percentage of the measured difference, depending on the programmed value. This new calculated value
will be the new reference for the following flight weight correction, and so on. The new value will
substitute the one stored while entering the formula in the database, and it is possible to see it by printing
the formula.
This functioning mode allows to obtain a progressive reduction of the correction value, and therefore a
greater accuracy of the actual flight weight; this action can be buffered more or less by changing the
programmed percentage value; by entering 100 there will be no buffering and the entire difference
between the foreseen flight weight and the measured one will be summed with the actual flight weight in
the following cycle.
A variable value from 1 to 100 represents the correction percentage which will be summed to the following
cycle (for example, 50 causes the adding or the subtraction to the current flight weight of 50% of the
previously calculated difference; in this way the correction will be buffered and less fast).
Higher is the set value, and quicker will be the flight weight correction in the following dosage; vice versa,
by putting low values it will gradually increase in the flight weight correction.
The use of the flight weight percentage correction is particularly useful in the dosage systems characterized
by not always constant flight quantities. In the case of silos, for example, the quantity of material in the silo
greatly influences the quantity of flight material to be taken into consideration.
6.16 Production programme
If this function is enabled, it allows to execute a production program cycle made up of up to 4 formulas that
will be executed automatically in sequence one after the other.
