Husky Altanium Delta3 - Using the Manual ART Function

v 2.3 — September 2015 Altanium Delta3
82 Using the Manual ART Function
7.6.1.1 Using the Manual ART Function
Due to a change to a particular zone, such as the replacement of a heating element or
thermocouple, an operator may need to reset the ART parameters for that zone. Poor control
of the zone may also lead an 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.
Once the system is started, the ART process automatically begins on all zones that have not
yet undergone the ART process. If a particular zone is not controlling properly when it has
reached its setpoint, ART can manually be run on that zone.
When ART is run manually on a zone, Altanium deletes its knowledge base on that zone and
recalculates 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.
To manually run ART on a zone, do the following:
NOTE:The system must be in RUN mode before the ART process can start.
1. Select the zone or zones to manually ART.
2. Touch the Start ART Process button to begin the ART analysis on the selected zone(s).

box and view/change the ART parameters. ART values can be changed
one zone at a time, while the controller is running.
