example, if the main water addition is 70 litres and the Admix Enable is set to 50% the Admix
signal will be activated when the added water reaches 35 litres.
The
Admix Amount
parameter is used to set the amount of Admix used in a recipe. This is
only used to display in the Mix Log.

The temperature correction settings are designed to allow system designers to compensate for
the effects of hot or cold weather on the reactions in the concrete by changing the target
moisture depending on the temperature. To this end, the settings allow the Target to be
changed by the
Temperature Coefficient

The
Local Auto Control
parameter sets the recipe to use the local recipe values for the AUTO
Mode loop rather than the parameters entered in the System Parameters section.
The
Proportional, Integral
and
Derivative Gain
parameters control the water valves during
AUTO Mode. They compare the current sensor value with the target and generate a control
signal for the speed of water addition (during the process the speed of water addition is
controlled initially by opening the coarse and fine valve fully and, as the error is reduced, by
closing the coarse valve and varying the pulse rate of the fine valve). Optimising these
parameters is described in the Operators Guide in the chapter ‘Using Moisture Control’.
