7.3.10 Changing the Power Output Control Method Setting

In hot runner process control systems there are two schools of thought in regards to how the
power output should be switched to the heaters. The choices are Zero Cross Control or Phase
Angle Control. Each method has its own set of pros and cons, but in all practicality they offer
very similar results. Only you can decide which method is right for your application.
Neo2 has the flexibility to run each individual zone in either mode, Zero Cross Control or
Phase Angle Control. The default setting is Z/C (zero cross) for all zones.
NOTE:
To change a zone's output control:

7.3.11 PID Control

Neo2 gives the operator the choice of using ART (automatic tuning), or a PID program
(manual tuning). The default setting is ART on all zones.
