INTRODUCTION TO THE OPERATION
The batching programs for 3/6/14 products are used to realize a mixture of different products, which
are loaded on a single weighing structure.
The instrument is able to load automatically a settable amount for each product, driving the relative
batching organ (even two-speed) through the dedicated contact.
The instrument has the following features:
-
Maximum 99 settable formulas (see section FORMULAS PROGRAMMING);
-
Formulas programming in fixed or variable steps (see section FORMULAS
PROGRAMMING);
-
Batching resume after blackout (see section RESUME BATCHING AFTER A POWER CUT);
-
Automatic fall calculation (see section FALL);
-
Autotare at batching start (see section AUTOTARE);
-
Tolerance error control (see section TOLERANCE);
-
Precision batching through slow function (see section SLOW);
-
Precision batching through tapping function (see section TAPPING FUNCTION);
-
Consumption storage (see section CONSUMPTION);
-
Print of batching data (see section PRINT AT CYCLE END);
-
Alarm contact (see section ALARM RELAY CLOSURE);
BATCHING START:
-
via keypad, setting formula and cycle number to be performed;
-
via external contact (see section BATCHING START FROM EXTERNAL CONTACT).
For further information on the batching sequence, see section BATCHING.
FORMULAS PROGRAMMING IN STEPS:
The programming products order in formulas is, by default, fixed and ascending (FIXED STEPS);
however it is still possible to program the products order, even repeating several times the same
product (VARIABLE STEPS).
CONSUMPTION STORAGE:
The instrument, at the end of every batching, stores the consumed amount for each product.
Consumption value can be viewed directly on instrument display in standby mode.
INSTRUMENT CALIBRATION:
The instrument calibration can be performed both with THEORETICAL CALIBRATION, setting the
instrument full scale and the load cells sensitivity (see section THEORETICAL CALIBRATION), and
with REAL CALIBRATION through SAMPLE WEIGHT (see section REAL CALIBRATION (WITH
SAMPLE WEIGHTS)).
ALARM MANAGEMENT:
If an alarm occurs during the batching, the instrument shows the alarm on the display, closes the
related contact (if enable) and waits for operator intervention to abort or continue the batching.
