Husky Altanium Delta5 - Art 2.0

v 2.0 — March 2023 Altanium Delta5
90 ART 2.0
To manually use ART on a zone, do the steps that follow:
NOTE: The system must be in RUN mode before the ART process can start.
1. On the ART Process screen, select the zone or zones on which the ART process will
manually be run.
2. Touch the Start ART Process button to start the ART analysis on the selected zone(s).
As each zone completes the ART process, a green check mark shows for that zone.
To cancel the ART process during its operation, touch the Cancel ART Process button.
7.9.2 ART 2.0
The use of the ART 2.0 tuning strategy gives added performance in comparison to ART
classic. With ART 2.0, the system is ready to mold much faster than before, with the
advantages that follow:
• Faster mold-tuning
• Reduced risk of tune-failure
• Reduced risk of mold-setup error
• Improved heating strategies
• Reduced dependence on local tuning skill
• Automatic zone classification
With ART 2.0, there is a shorter time to restart through improved heat-up strategies with the
potential to reduce resin degradation, which could save some material, time, and energy.
The system is able to automatically classify the type of heater that each zone controls with
the use of the ART 2.0 algorithms. In the System Setup screen, you can enter a Heater
Classification Gap that determines which zones are tips and which ones are manifolds.
A heat capacity value, measured as zone gain in decibels (dBG), is returned by the control
card that can be used for determining the heater type. Values for all the zones are sorted in
ascending order and then the widest gap found between zones is determined. If the widest
gap exceeds the Heater Classification Gap, then the zones on the lower side of the gap are
tips and the other zones are manifolds. If no gap is wide enough, then no action can be taken
because the system cannot determine a tip from a manifold.
For typical hot runners a value of 5 dBG or 6 dBG is ideal, but there could be specialized
molding applications where these defaults are not applicable.
Figure 7-17 shows examples of how the classifications (tip/manifolds) are determined. The
gains of five zones are measured. The gains are sorted from smallest to the largest with gaps
shown between the gains. With the use of the Heater Classification Gap value that you enter
in the Heats Setup (Control Page 3) of the System Setup page, ART 2.0 counts the gaps
between the measured gains and assigns each zone a tips or manifold classification. With a
Gap setting of 5, zones with lower gain measurements (and separated by 4 gaps or less) are
tips, while zones with higher gain measurements (and separated by 5 gaps or more) are
Manifolds. With a Gap setting of 6, zones with lower gain measurements (and separated by
5 gaps or less) are tips, while zones with higher gain measurements (and separated by 6 gaps
or more) are Manifolds.
