This system has been designed to solve weighing problems of batching systems up to 3 scales on the same production line. The system can control up to 3 scales simultaneously with management of 22 to 31 different products, plus 6 products for manual additions. The WRBIL 26/50/1+1SCA and 22/50/2+1SCA can also control an unloading scale. The system allows the connection to PC with Supervisory Software PROGWRBIL (optional) to store every batching and trace the raw materials used.

The system is composed of:

• WR main unit in DIN box (96x192x150 mm, drilling template 92×186 mm) for panel mounting. 18-key polycarbonate keyboard. One 6-digit numeric display (14mm high), 7 segment LED. One semialphanumeric LCD display with two lines x 16-digit (5mm high). IP54 front panel protection.
• Three/four 8-output relay modules, dimensions 93x126x h 60 mm, contacts rating 115VAC 0.5A; suitable for Omega-DIN rail.
• From one to three W100 weight transmitters  – 230 VAC / 24 VDC power supply 2 A.

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. In case manual additions, the ‘manual additions’ contact will be closed at the batching start of any product, it will open again at the ‘manul additions’ input closing. In case of printer connection, WRBIL sends data for printing at the end of batching.

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.
