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.
Tune the drive.
Enter a recipe.
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).
