Multi-Product Dosage Functioning

DATABASES

• Database of 16 selectable products/phases which may be:
  - Automatic dosage;
  - Manual dosage, with possibility of managing a control light;
  - Complete or partial unloading;
  - Fractioned unloading, for dividing all the dosed material in equal quantities;
  - Timer, for enabling mixers, burners, or stirrers for a preestablished time period;
  - Pause, for allowing the manual operations of the operator;
  - Manual weight, for adding pre-weighed quantities to the dosage.
• Database of 15 formulas, each one can contain:
  - up to 8 products/phases with target, speed change threshold, flight, +/- tolerance;
  - minimum tare and maximum tare values.

FUNCTIONING OF THE DOSAGE IN UNLOADING

• 1. Once the dosage start command is received, the instrument:
  - verifies that the quantity of material is sufficient to execute the programmed dosage cycle and that the weight is stable,
  - executes the automatic tare and the enabling of the automation through its dedicated outputs: the dosages start at maximum speed.
• 2. Once the speed switch threshold is reached, the dosage slows down through its dedicated output.
• 3. When the TARGET is reached and the configured flight weight is missing, it disables the dosage output, and then it waits (for the configured time) for dropping the material.
• 4. Tolerance test on the dosed weight.
• 5. Storage of the formula consumptions and increment of the dosed general total.
• 6. Waits for the start of the new dosage or automatically restarts with the following cycle.
