This batching system has been designed to solve weighing problems linked to the preparation of the concrete and to control batching of aggregate materials, cement, additives by weight/pulses and water by weight/pulses (max 20 Hz). It is possible to measure the humidity of two aggregates with the automatic correction of water and aggregate quantities depending on the humidity acquired. The WRMDB system allows to control up to 4 scales.

The WRMDB system has been designed to solve weighing problems linked to the preparation of the concrete and to control batching (max 50 FORMULAS) of aggregate materials, cement, additives by weight/pulses and water by weight/ pulses (max 20 Hz). An important characteristic is that aggregates batching can be started even if the other scales (cement, aggreg., water) have not finished the batching cycle. The system allows the connection to PC by Supervisory Software PROGWRMDB (optional) or printer to print formulas, stocks, and batching data.

Operation: The operator (or external logic) starts batching and the WR verifies that the approval contact is closed and the weight is below the minimum weight on each weighing scale, then checks the stocks. It then executes the autotare and closes the contact of the first aggregate, cement, additive, water set in the formula. When the programmed value minus the slow and fall values 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, the microprocessor opens the product contact and when the waiting time has elapsed, memorises consumption and stocks, then closes the contact of the next product, and so on through to the last product. If at the end of baching the dosed quantity is higher that the quantity set as Tolerance, WR shows the out of tolerance alarm. Following WR closes the cycle end contact for that scale, which remains closed until the minimum weight is reached and after the safe emptying time has elapsed. The mixing time contact will remain closed for the time set until the unloading phase is finished for all the scales. In case of printer connection, WR sends data for printing. In case of PC connection, WR sends data to be stored.

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 Freatures:

• 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.
• 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).

This system has been designed to solve weighing problems of batching systems up to 3 scales on the same production line. The system allows the connection to PC with Supervisory Software PROGWRBIL (optional) to store every batching and trace the raw materials used.

Key Features:

• Constants Menu: product name; maximum weight; minimum weight; automatic or manual fall; slow value; tapping phase; tolerance value; association between product and desired relay; pause time and safe emptying time for each scale; consumption and stock for each product; production for formula. Constants Menu protected by password: idioma setting; setting the times for alarms “no entry product” and “no unload product”; association between product and scale; emergency scale.
• Formulas Menu: up to 50 formulas, can be stored in the permanent memory. Programming can be carried out according to the sequence desired. The following steps can also be programmed: waiting time before passing to next batching; partial or total unload of the dosed quantity before fi nishing the formula batching; free relay opening and closing; products for manual additions.
• Batching Menu: keyboard automatic batching as well as desired cycle setup and the formula’s percentage; batching start by external contact of the last formula for one cycle only.
• Total Menu: each product consumption, each product stock calculation, executed cycles memorization and dosed Kg per each formula.

Operation:
The operator starts batching via keyboard or PC by selecting the formula and setting the desired percentage, otherwise by closing the start external contact starts the batching of the last formula previously memorized. The WRBIL verifies that the approval contact is closed and the weight is below the minimum weight on each loading scale, for the unloading scales WRBIL verifies that the products and stock are enough for all batchings, then closes contemporarly the contact of first product for each scale. Once the value programmed in formula minus the slow and fall values is reached, the system closes the slow contact and the product contact can be opened and closed according to the programmed work and pause times (“tapping” phase). When the programmed product value minus the Fall value is reached, the microprocessor opens the product contact and when the waiting time has elapsed, memorises consumption and stocks, then closes the contact of the next product, and so on through to the last product. If during the batching the weight doesn’t increase (loading scale) or decrease (unloading scale) like the value of the setup divisions in the setup time, the system will go under the alarm condition. If at the end of baching the dosed quantity is higher that the quantity set as tolerance, WRBIL shows the out of tolerance alarm. As soon as the batchings of a loading scale are finished, the cycle-end contact will be closed, and it will be open again when the scale unloading is finished, as soon as the programmed minimum weight has been reached and the safe emptying time has elapsed; for the unloading scale the cycle-end contact will be open as soon as the the safe emptying time has elapsed, after that the following batching will start. If during the unloading phase (cycle end closed) the weight doesn’t decrease like the value of the setup divisions in the setup time, the system will go under the alarm condition.

It is possible to select two different operating modes:

• The second batching cycle can be started even if the other scales are at first batching cycle(max 1 cycle of displacement).
• The second batching cycle can be started only if the other scales have finished the first batching cycle.
