Configuration which allows to manage a dosage system in unloading of a single product, useful for dividing the quantity of materials of equal weight or extract precise quantities from the silo, with management of the reloading.
Method UNLOAD: the weight in the silo decreases until the set target weight is reached.
Main features
- basic functions (clearing, tare, and weight printing);
- automatic dosage in unloading;
- automatic management of the reloading of the silo using a dedicated contact, with programmable filling start and end thresholds;
- database of 40 different formulas; target, speed change threshold, flight, +- tolerance, programmable for each formula;
- quick switch of the dosage target through a dedicated key.
- dual dosage speed (approximate and fine), managed through output active in constant mode or with bleeding function, with programmable on/off time.
- start / pause dosage from keyboard or through enabling of the inputs.
- automatic printing of the dosage data.
- storage and printing of the consumptions: consumption of each formula, formula consumption, general total dosed. printouts may be quickly recalled from the keyboard.
- automatic correction of the flight weight, with programmable incidence degree.
- number of programmable dosage cycle repetitions; enabling of the infinite dosage.
- tolerance test on the dosed weight, with guided correction through simple messages to the display.
- analogue output (optional) proportional to the weight or to the dosage speed.
- check of the maximum dosage time and alarm management
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
- once the speed switch threshold is reached, the dosage slows down through its dedicated output
- when the TARGET is reached, the configured flight weight is missing; it disables the dosage output, and then it waits (for the configured time) for dropping the material
- tolerance test on the dosed weight
- storage of the formula consumptions and increment of the dosed general total
- waits for the start of the new dosage or automatically restarts with the following cycle
