VISIONTRAK Performance Monitor (General Information)VISIONTRAK is active when header is engaged and in some diagnostic modes. Determine grain size of crop being harvested. Seed size may be selected by pushing seed size button (B). Seed size indicator (G) is located in the center of the VISIONTRAK display. It will change to show the selected seed size. VISIONTRAK display (A) checks the grain loss by measuring a representative sample of losses over the cleaning shoe sensors and through the separator. A change in loss rate is indicated by the activity indicators. Four narrow activity indicators (D), (E), (I) and (J) show the activity on each of the four sensors. VISIONTRAK can be set to two modes: Standard mode averages the shoe sensors and averages the separator sensors. An optional mode shows the activity of each individual sensor. These activity indicators will not change the sensitivity with a change in the system calibration. Wide total activity indicator (H) shows the total seed hits from the four sensors. This total can be adjusted so that normal performance will show the bar mid point. To set VISIONTRAK, tune the combine's performance to an acceptable loss level. While operating at this desired combine performance, press calibration button (C). This will enter the current operating characteristics into memory and center the center bar graph (total activity indicator) display. The calibration reference number (F) will also be shown for future use. The system is now set up to help the operator maintain the combine performance. VISIONTRAK can also be used to detect plugged or closed sieves and chaffers. A sudden upward movement of bar graphs when field conditions are unchanged, can indicate that the sieve or chaffer is plugged or closed. When this happens, stop the combine and correct the problem. |
