The system has been designed to control basic bacthing with two or three scales with one litre-counter (max 20Hz); suitable in particular for concrete asphalt plant. The DOS2005 system allows to control up to 3 scales. The system is composed of:

• Main unit: weight indicator series DOS2005
• from one to two weight indicators model RIPE
• one 6-output relay module

Key Features:

• Programming up to 20 formulas.
• Zero-setting and calibration are performed from front panel keys.
• Checking of the load cells connection.
• Batching start via keyboard by setting desired cycles (max 9999).
• Batching start from external contact for only one cycle.
• Option to execute autotare on first component.
• “Tapping” function: It is possible to select the slow-on and slow-off times.
• Automatic fall calculation for each product.
• Consumption memorization x 10, x 100, x 1000.
• Possibility of resuming batching cycle from point of interruption following a blackout.
• The litre-counter quantity can be modified also during the batching phase.
• Possibility of manual batching by keyboard.
• Regarding the display of the scales “B” and “C”, is able to read up to 4 digit; after exceeding the value 9999 the display shows the value with movable point (for example 11.50 means 11500).
• PASSWORD: It is possible to enable a password to protect the access to the constants programming.

Operation:

The operator (or external logic) starts batching, DOS2005 closes the litre-counter contact and verifies that the approval contact is closed and the weight is below the minimum weight on each weighing scale. It then executes the autotare (if enabled) and closes the contact of the first product of each scale. When the programmed value minus the slow value is reached the product contact can be opened and closed according to the programmed work and pause times (“tapping” phase). Once the programmed product value minus the fall value is reached, DOS2005 opens the product contact and when the waiting time has elapsed, memorises consumption and closes the contact of the next product, and so on through to the last product. Following this, DOS2005 sends data for printing and closes the cycle-end contact of the scale which has finished the batching. The cycle-end contact will remain closed until the unloading phase; when the weight has reached the minimum weight and after the safe emptying time has elapsed, the instrument opens the cycle-end contact. If more than one cycle has been programmed (or the operator sends a new start by means external button), the scale that has finished the unloading and close the approval contact can start a new cycle even if the other scales have not finished the batching cycle (max one cycle of displacement).
