ends and it is not possible to end the cycle, once the set time has passed, the error is signalled; the
operator must manually fill the stockpile silo.
By pressing for an instant the external INPUT 1 or the START button, the cycle starts again in the condition
in which it was in before the error took place.

Formula execution modes
The instrument can execute the formula in 2 ways depending on how the system has been configured (see
the
BATCH Functions>> Formula>> Formula’s target setting mode
)
:
Formula weight
Setting of the total weight
First free component
6.12.1
Formula weighs
If the “Formula weight” functioning mode has been enabled in the set-up, the dosage is carried out as set in
the formula.
In other words the instrument executes the formula by dosing the programmed weights, without any
recalculation
6.12.2
Setting of the total weight
In the “
Setting of the total weight
” functioning mode one sets the total weight to dose, in the database
unit of measure, and, on the basis of this total, the instrument recalculates the weights to be dosed of all
the loading activities which make up the formula, proportionally to the target of the basic formula.
The recalculation of the weights has no effect on the partial unloading single component formulas and on
the single unloading activities.
In this mode one must enter a basic formula, in which each activity covers a certain percentage in respect
to the target.
It is advisable to enter, for each activity, a target equal to the percentage which that activity should have in
respect to 100%.
After this, one enters the total weight which one wants to dose.
EXAMPLE: 1000kg
The instrument automatically recalculates the weight to be dosed for each activity of the selected formula,
on the basis of the percentage which these have in respect to the formula’s target.

All the formula weights are converted into the database’s unit of measure and decimals, with all the
eventual roundings.
