BATCHING
Note: In case of alarm, the batching may be canceled by pressing the ESC button or by closing the
STOP input.
After having selected the formula and set the desired number of batching cycles, the first batching
cycle starts as follows:
1.
The instrument will ensure that:
-
the formula has been programmed, otherwise it will display the alarm  .
-
the amount set in the formula does not exceed the set maximum weight (

), otherwise
the message  is displayed.
-
the input IN3 (if it is set as Approval) is closed, otherwise the message

will be
displayed; close the input IN3 to start the batching.
-
Only if  is set: the gross weight is lower than the minimum weight (  ), otherwise the
alarm
 
is displayed (it is always possible to force the batching start by pressing the
ENTER key).
-
Only if

=

:
-
If the consumed amount exceeds 999000, the

message appears for a second.
-
If the consumed amount exceeds 999999, it is automatically set to zero.
2. Once the above listed conditions are met, the batching of first product programmed in formula is
started; if the
 time is set and the product is not loaded for at least 20 divisions during
this time interval, the relative alarm

is displayed.
3. The number of the product to be batched (e.g.

) is displayed for 1 second and then the net
weight; the product relay closes;
4. Only if  is set: once the value set for that product has been reached, minus the fall and
slow values, the SLOW contact closes (if foreseen); if tapping values have been set, the product
contact carries out opening and closing cycles according to

and

times;
5. Once the value set for that product has been reached, minus any fall value, the product contact
is opened interrupting product flow;
6. After the contact opening, the system shows the weight preceded by the letter

and waits:
-
Only if

=

: The waiting time has elapsed (

).
-
Only if  =  : The START input has been closed or the ENTER key has been
pressed.
-
Only if

=

: The weight is stable.
7. If the tolerance (

) is set and the batched quantity is lower than the set quantity minus this
value, is made only one attempt of finishing re-start, in order to improve the batching precision.
In such a case, the PRODUCT contact is closed and returns to step 5, otherwise the
 alarm
appears. If instead, the batched quantity is greater than the set amount plus this value, the

alarm appears. Press ENTER to cancel the alarm and go on with the batching.
8. Only if

=

: consumption of the product just batched is stored;
