3-2 Initial Operation
The control system is factory-programmed. However, specific values need to be verified prior
to operation (basic parameter settings). The input values will be saved and still be available if
the feeder is switched off, or a power failure occurs. Please refer to Appendix B for these
values.
Extrusion operations require a “span factor” to be entered into the basic settings. These
are also explained in Appendix B.
Prior to putting your new Digital Dosing feeder on-line:
Configure the feeder control for motor speed, encoder pulses, sensors, and alarm options.
o
Tune the drive.
o
Enter a recipe.
o
Calibrate the additive weight for best accuracy.
NOTE: Recipe parameters are different for Injection Molding, Extrusion –
Constant, and Extrusion - Proportional operation. See each individual
section for details
Once the feeder is on-line, recipes can be saved for later recall
(up to 50 standard).
