7.4.3 Control Method

The use of Active Reasoning Technology for control eliminates the tasks of using self-tune or
"automatic" tune PID, PIDD or PPID algorithms. ART performs all of these tasks without the
need for manual intervention. ART is based on control algorithms which through the use of
fuzzy logic, perform all functions as a normal PID control would. ART however is far better
due to its ability to see the whole picture and automatically adapt to the individual
characteristics of each heater.

7.4.4 Changing the Control From PID To ART

Neo2 can automatically adjust the control algorithm to suit different heater requirements.
This control method is referred to as ART. ART is the default control method.

7.4.5 When to Use the Manual ART Function

Due to a change to a particular zone, such as the replacement of a heating element or
thermocouple, the ART parameters for that zone may need to be reset. Poor control of the
zone may also lead the operator to make this decision. For example, the temperatures may
be consistently swinging over and under setpoint, yet not triggering an alarm. This is not to
be confused with shear heat from the material, which appears as sudden increases in
temperature with no undershoot.
When ART is manually run on a zone, Neo2 deletes its knowledge base on that zone and "re-
thinks" the control process. It then stores this data and uses it to calculate the proper output
to control this zone best at setpoint. Use this function sparingly and only permit highly
qualified individuals to use it. The molding process may be interrupted if ART is run on
several zones at one time, but this is rare. It is best to run ART on a zone once it is at setpoint.

7.4.5.1 Running ART on a Zone

When Neo2 runs a mold for the first time it automatically performs the ART process on all
zones that have ART selected. If a particular zone is not controlling properly when it has
reached its setpoint, ART can be manually run on that zone. The system must be running and
ART must be selected for that zone on the PID/ART screen. If the zone had been previously
ARTed, ART will be displayed on the zone button. If it has never been ARTed, the zone button
will display NO ART.
