Chapter 3 Plant Operator Controls
A plant operator will rarely need to adjust parameters, therefore no access is required to the main menu.
To access the plant operator controls press the Recipe / Mode button
on the Overview
screen. The following screen will be displayed.
Figure 6 - Recipe/Mode Screen
The recipe list (1) lists all the recipe of the system. It is possible to choose which recipe is selected by
pressing the line which displays the recipe you require.
The scroll buttons (2) can be used to move up and down the list.
If there are a lot of recipes the find recipe button (3) can be pressed. A recipe number can be entered
and the system will find the desired recipe.
In Preset mode it is not possible to adjust moisture targets as the system will add only fixed amounts of
water. In AUTO or CALC mode it is not possible to adjust the water values as the water addition is
controlled to the water target. See Chapter 5 for an explanation of the different water addition modes.
If it becomes necessary to adjust the water addition slightly to correct for workability it is advisable to
adjust the amount of admixture used. If this is not possible the Main water trim parameter can be used
to adjust the overall amount of water added to maintain workability. If it is found a certain amount of
trim is always required personnel with supervisor access should be notified to re-calibrate the mix. The
procedure for this is described in Chapter 8 section 2.8. For detailed descriptions of each parameter
see Chapter 6.
