3.2 Initial Operation
The control system is factory-programmed. Nevertheless, specific values need to be
predefined or checked prior to operation (basic parameter settings). The input values will be
saved and will still be available if the unit 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. Please refer to Appendix B.
Prior to putting your new Digital Dosing Additive Feeder on-line:
• You must enter a recipe and calibrate the feeder.
• Recipe parameters are different for Injection Molding, Extrusion - Constant,
and Extrusion - Proportional operation. See each individual section for
details.
• The calibration method is the same for all processes.
• Once the unit is online, recipes can be saved for later recall (10 maximum).
