System Design
Auto-Track
4.4
Auto-Track can be used during any of the mixing phases of the mix cycle to automatically adjust
the mix time depending on the homogeneity of the material in the mixer. There are four sets of
parameters in the System Parameters page which control when the Auto-Track will finish the
mix phases. These can be over-ridden in the Recipe Parameters if needed. In the recipe
settings it is possible to select which mixing phases use auto-track and which do not.
Moisture
Figure 46 shows a typical mix trace showing the Auto-Track timing. The Auto-Track monitors
the moisture and identifies the stable point for the Dry Mix and the Wet Mix times. It requires
the variation in the sensor value to be less than the Mix Deviation parameter for the period of
the Mix Time parameter before continuing to the next mixing phase. If the time reaches the
recipe Mix Time parameter then an alarm is activated.
