Note * In the case of built-in-automatic program mode weighing, the set point data is held until batch finish since batch start. Therefore, a set point altered during batching takes effect after “batch finish” is output. * “Within limit” is on in the chart above.
6-6 CALF-14=“3” Weighing Mode (with Supplementary Flow) (Normal batching with supplementary flow in built-in automatic program mode) Supplementary flow automatically turns on the dribble flow for the specified time when the loaded weight is not sufficient. To make supplementary flow, set the “maximum supplementary flow times, SQF-08,” to other than 0, and the “supplementary flow open timer, SQF-16,” and “supplementary flow close timer, SQF-17,” to their respective times.
Note * In the case of built-in-automatic program mode weighing, the set point data is held until batch finish since start of batching. Therefore, a set point altered during batching takes effect after “batch finish” is output. * The chart above is the case that a judgement result becomes “Within limit” at the third judgement after supplementary flow action has been made twice.
6-7 CALF-14=“4” Weighing Mode (Loss-In-weigh in built-in automatic program mode) Output signal Output condition Zero band Full Full-flow Medium-flow Dribble-flow Over limit Under limit Final Final Final Final Full - Optional preliminary Preliminary Free fall + Over limit ≤ ≤ ≤ ≤ < Gross weight Gross weight Net weight Net weight Net weight Net weight Net weight ≤ Zero band < Final - Under limit • When an output condition is established, full flow, medium flow, and dribble flow outputs are turned off
Note * * SQF-21/ SQF-22 setting enables to add automatically the Final weight to Zero band or Full. Therefore there is always enough ingredient left in the hopper for a measurement. In the case of built-in-automatic program mode weighing, the set point data is held until batch finish since start of batching. Therefore, a set point altered during batching takes effect after “batch finish” is output.
6-8 CALF-14=“5” Weighing Mode (Nozzle controlled weighing mode) Output signal Zero band Full-flow Medium-flow Dribble-flow Over limit Under limit Final Final Final Final Output condition - Optional preliminary Preliminary Free fall + Over limit ≤ ≤ ≤ < Gross weight Net weight Net weight Net weight Net weight Net weight ≤ Zero band < Final - Under limit • When an output condition is established, a relevant output terminal is turned on or off.
Note * * * In the case of built-in-automatic program mode weighing, the set point data is held until batch finish since start of batching. Therefore, a set point altered during batching takes effect after “batch finish” is output. Chart above is of the case; • “Acceptable weight” is on. • A judgement result becomes “Acceptable weight” at the third judgement after supplementary flow action has been made twice.
