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.
-
IN3 input (if it is set as Approval) is closed, otherwise the message

will be displayed;
close the IN3 input to start the batching.
-
the gross weight is lower than the minimum weight (  ), otherwise the alarm   is
displayed (however it is possible to force batching start by pressing ENTER).
-
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 is started and the SET and PRESET
contacts switch depending on the

parameter (see section OPERATION SETTINGS ). From
now on, we assume the parameter  = 2 (default); so that, SET and PRESET are closed.
3. If during the batching, after setting the time

, the product is not loaded by at least 20
divisions within this interval of time, the

alarm message will be displayed.
4. The PRESET contact will be opened, as soon as one of the following conditions is reached:
-
Only if  is set : once reached the set value minus the slow value;
-
Once reached the preset value set in formula;
5. If a tapping value has been set, the SET contact will be opened and closed according to the

and

times;
6. Only if

is set : the instrument does not verify the reaching of Set value until the
COMPARISON TIME has elapsed.
7. As soon as the SET value in the formula minus the possible fall value is reached, the SET
contact will be opened and the product flow will be interrupted;
8. After the opening of the SET contact, 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.
9. 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 SET contact is closed and returns to step 7, 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.
10. The system enters the cycle end phase:
