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 Sequence Signals, even with with very few inputs when necessary.
The eDART uses its internal Machine Sequence signals to compute summary values such as Effective Viscosity etc.
It also uses Machine Sequence signals to make decisions for control (V->P Transfer, Valve Gates, Alarms and Diverter Controls, Basic 3-Stage etc.)
The more inputs the customer wires up the fewer manual steps required to get good sequencing information. With few inputs he must set and adjust things to get good sequencing.
The names given to the various inputs are critical. The eDART is, after all, a computer and cannot guess at what you meant to say rather than what you did say. Incorrect names given on Sensor Locations will create incorrect data.
Operating Rules of Thumb – Memorize These
Wire up all possible sequence signals as soon as you can (especially in a permanent installation) to avoid the chance of forgetting those manual steps that are required without them. Demos require fewer or no sequence signals unless you want to show full capability and how the user does not need to set things if they are all wired up.
Carefully check the On/Off status in Sensor Locations before accepting. Operate the machine and watch at the little green lights.
Name the sequence inputs correctly.
If you don’t know what a signal is doing, call it Not Used (or Unknown for analysis purposes). If a signal does nothing, call it Not Used.
Always set the fill volume once the process has stabilized (until we incorporate Auto-Set Fill Volume into the sequencer).
