At the completion of the wet mix period and if the mix moisture content is within the set tolerance limits, the external batch control system will be signalled that the mix is ready for discharge. Alternatively, if the moisture content is outside the pre-defined limits an alarm is activated and the mix is held in the mixer until corrective action has been taken and the alarm accepted. This feature not only provides a self-checking facility to verify that the calibration is correct, but in the event of any error, enables corrective action to be taken.

The system can operate using a number of different sequences to meet all operational requirements, including the pre-wetting of aggregates, control of admixture addition, etc.
All parameters are configurable through the front panel.
