1st Stage + 2nd Stage = Injection Forward

Tip # 137 explained how to correctly name “First Stage” instead of Injection Forward because Injection Forward, in eDART land, is supposed to go off at the end of hold. Naming First Stage correctly lets the eDART create Machine Sequence / Injection Forward...

Sequencing Made Possible with Hydraulic Screw Motor Pressure

We find that many of are customers are getting charged dearly for adding sequence outputs to a machine for screw run, injection forward and so on. If you are using a machine with a hydraulic screw motor then there may be a way to detect the screw motor running using a...

Injection Forward ≠ First Stage

We have had some problems when hooking up to machines with the nomenclature for “Injection Forward”. Many times machines call the filling (speed) phase “Injection” so our customers get this signal wired in and call it “Injection...

V->P Transfer Ends Fill

Recently I got a call from a customer that had a fill volume set properly (auto or manual) in order to get good viscosity, fill time and other sequencing information. But Machine Sequence / Fill signal insisted on going off earlier than the fill volume he had set. All...

A Summary

Well, that about wraps it up for eDART Sequencing. For now, anyway. Let’s quickly review the important points. The eDART sequencer uses Seq. Module Inputs, stroke, injection pressure and others to create Machine Sequence signals. The sequencer creates Machine...

How Controls Depend on it

I hear after sending yesterday’s tip that I got a little carried away with too much information in one message. If so, you can just file it for later reference if you need it.Today, in more abbreviated form, we discuss how controls depend on sequencing. Pack to...
